Tools
| Tool | Description | Behaviour |
|---|---|---|
| apps_build | Queue a durable app build and immediately return its ID and status URL. Use BuildStatus to retrieve progress and the completed app. Reuse request_key on retries. Builds survive server restarts | Not declared |
| apps_builds | List your app build jobs and outcomes | Not declared |
| apps_buildstatus | Read your saved app build status by ID. Poll until complete or failed; the same ID survives restarts. | Not declared |
| apps_collection | List your saved apps and their source references | Not declared |
| apps_create | Create an app — a small, self-contained HTML tool hosted here. Takes the HTML; apps_build writes it for you from a description Apps run in a sandbox. Use fetch('/api/v1/<service>/<method>') or mu.service(name, method, args); mu.api does not exist. Direct external fetch is blocked. Inspect real service schemas and data before coding; never invent fields, rankings or claim runtime verification from static checks. | Not declared |
| apps_edit | Edit an app you own — its name, description, tags, icon, HTML or price. Fields left out keep their value Apps run in a sandbox. Use fetch('/api/v1/<service>/<method>') or mu.service(name, method, args); mu.api does not exist. Direct external fetch is blocked. Inspect real service schemas and data before coding; never invent fields, rankings or claim runtime verification from static checks. | Not declared |
| apps_embed | Show a saved micro app in the conversation. Embedding preserves access permissions and does not publish the app | Not declared |
| apps_fork | Fork an app into your own account, to change independently of the original | Not declared |
| apps_read | Read an app or build status by slug, including source HTML for apps you own | Read-only |
| apps_search | Find your saved private micro apps by name, description or tag | Read-only |
| apps_test | Test an app by checking its HTML and checking supported SDK calls; this is not browser execution, so an author finds out what is broken without opening it | Not declared |
| archive_list | With a kind, the most recent entries of it. Without one, what kinds are archived and how much of each | Read-only |
| archive_search | Search everything this instance has collected, across news, video, markets and posts at once. Use it when the question crosses a service, or when you do not know which service would hold the answer; news_search is narrower and better when you know it is news | Read-only |
| blog_create | Publish a post to the caller's blog. For anything meant to be read later by other people — notes, write-ups, announcements. For a private note to yourself, prefer files or memory | Not declared |
| blog_delete | Delete one of the caller's own blog posts, by id or title. Refuses posts written by anyone else, and refuses an ambiguous title rather than guessing. Irreversible, so confirm with the user first | Destructive |
| blog_list | Read recent blog posts — titles, snippets and ids | Read-only |
| blog_read | Read one blog post in full, by id or by title. Use after blog_list has found a candidate and the summary is not enough | Read-only |
| blog_update | Edit one of the caller's own posts. Fields left out keep their current value | Not declared |
| bookmarks_add | Save an article, video, blog post or link privately. Re-saving preserves its note | Not declared |
| bookmarks_annotate | Set or clear a private note on one saved item | Not declared |
| bookmarks_delete | Remove one of your saved items | Destructive |
| bookmarks_get | Read one saved item and its private note, with available archived text. Videos have descriptions, not transcripts | Read-only |
| bookmarks_list | Find your saved reading by text or kind, newest first. Private notes are searched too | Read-only |
| browser_read | Open a page in a real browser and read it after its JavaScript has run. Use it when web_fetch comes back empty or with only a nav bar, which is what a page that builds itself in the browser looks like to a plain fetch. web_fetch is free and is the right first try; this costs, because it runs a browser | Read-only |
| browser_shot | Photograph a page and get back a URL for the picture. What it looks like, rather than what it says — a chart, a layout, a page whose content is an image. Ask for full to capture past the first screenful | Not declared |
| chat_messages | Read the recent conversation in a discussion room | Not declared |
| chat_rooms | List discussion rooms that currently have activity | Not declared |
| chat_send | Say something in a discussion room, as the caller. Use chat_rooms to find the room id | Not declared |
| chat_source | Read one stored message owned by the caller, by id | Not declared |
| chat_sources | List stored message ids owned by the caller | Not declared |
| contacts_add | Save someone to the address book. Adding a name already there updates it rather than making a second card | Not declared |
| contacts_delete | Remove someone from the address book | Destructive |
| contacts_find | Look someone up in the address book by name, part of a name, or address. Use this before sending mail to a person named rather than addressed | Read-only |

| docs_list | List your documents, most recently changed first, with an optional search over titles and bodies. Use this to find an id | Read-only |
| docs_read | Read one of your documents in full, by id or by exact title | Read-only |
| docs_write | Write a document — a title and a markdown body. Pass an id to replace one you already have. Private unless you set public. For something long enough to re-read; for a short thing to remember, use notes | Not declared |
| events_create | Schedule a reminder or event at a given time; optionally repeating, and optionally running a prompt through the agent when it fires | Not declared |
| events_delete | Cancel an event by id | Destructive |
| events_free | Find when the caller has nothing booked — open slots of a given length, within working hours | Read-only |
| events_list | List the caller's upcoming events and reminders, each with its id | Read-only |
| events_read | Read one schedule owned by the caller | Read-only |
| events_update | Update one of your scheduled events without changing its id. Omitted fields stay unchanged; empty notes, prompts or recurrence clear them | Not declared |
| files_delete | Delete a file you own | Destructive |
| files_driveread | Read the caller's connected Google Drive. Read-only; connect in Account first. | Not declared |

| files_share | Make a file readable by anyone with its URL, or private again | Not declared |
| flights_airport | Report what is happening at an airport right now: what is on the ground, what is on approach and what is climbing out. Live positions, not the timetable, so it says nothing about scheduled or delayed departures | Not declared |
| flights_overhead | List the aircraft flying near a location right now, nearest first, with altitude, speed, heading and distance. Live positions broadcast by the aircraft themselves, not a schedule | Not declared |
| flights_status | Scheduled, estimated and actual flight arrival/departure times from Aviationstack. Requires a configured provider. | Not declared |
| flights_track | Find where an aircraft is right now by flight number ('BA117'), radio callsign ('BAW117') or registration ('G-ZBKL'). Only sees aeroplanes that are airborne and in range of a receiver — not finding one does not mean the flight was cancelled | Not declared |
| food_hygiene | Food hygiene ratings for UK businesses, from the Food Standards Agency inspections. Takes a business name, a town or postcode, or a lat/lon to look around | Not declared |
| food_product | Look up a packaged food by its barcode — name, brand, ingredients, allergens, nutrition per 100g, Nutri-Score and how processed it is | Not declared |
| food_search | Find packaged foods by name or brand, with the barcode of each so one can then be looked up in full | Read-only |
| groups_create | Create a private group | Not declared |
| groups_list | List your groups and pending invitations | Read-only |
| groups_read | Read a group you belong to and open its chat | Read-only |
| groups_update | Manage invitations, membership and roles. Accept invitations before accessing a group. Removing yourself leaves; owners must transfer ownership first. Delete closes the group for everyone. | Destructive |
| hazards_alerts | Current disasters worldwide from GDACS — cyclones, floods, volcanoes, wildfires and earthquakes — with an alert level of green, orange or red. Pass lat/lon to ask about somewhere in particular | Not declared |
| hazards_floods | Flood warnings and alerts in force in England, most severe first, from the Environment Agency. The one hazard here that is a forecast rather than a record — a warning says flooding is expected, which is something you can act on. Optionally near a point. England only, and the answer says so | Not declared |
| hazards_quakes | Recent earthquakes worldwide from the USGS, with magnitude, place and how long ago. Pass lat/lon to ask about somewhere in particular, min for a magnitude floor, and period for hour, day, week or month | Not declared |
| images_daily | Retrieve the current daily image or a date | Not declared |

| images_update | Edit metadata on an image you own | Not declared |

| islam_read | Read the full Islamic source passage from an islam_search result, with its source and reference. Preserve distinctions between original text, translation and commentary. | Read-only |
| islam_search | Search Aslam.org's Quran, hadith, names of Allah, Seerah, Ghazali, IslamQA, adhkar and Riyad us-Salihin. Returns reference excerpts, not generated answers. Distinguish Quran and hadith from biography and scholarly interpretation; cite the source. | Read-only |
| mail_gmailread | Read the caller's connected Gmail. Read-only; connect in Account first. | Not declared |
| mail_gmailsearch | Search the caller's connected Gmail. Read-only; connect in Account first. | Not declared |
| mail_inbox | List the account's most recent messages — read my mail, check my inbox | Read-only |
| mail_info | How to reach the caller here: the handle, the email address if this instance has a mail domain, and whether mail from outside can arrive at all. Pass a tag for a separate one (you+tag) — give that out, then read only its messages with mail_inbox(tag) | Not declared |
| mail_markread | Mark specified inbox message IDs, or explicitly all current inbox messages, as read. Changes read status only; does not read, summarize or triage the content. | Not declared |
| mail_read | Read your correspondence by id in bounded body-character pages, including attachment names. Follow the returned next offset for the rest. Omitting id retains the legacy inbox summary | Read-only |
| mail_search | Search the account's mail and return matching messages | Read-only |
| mail_send | Write to somebody, as you. A username reaches them on this instance and is free; a full email address leaves over SMTP under this instance's domain, so a reply comes back to your inbox, and is charged. Resolve a name with contacts_find first. Mail that leaves needs MAIL_DOMAIN configured on the instance | Destructive |
| mail_source | Read one stored message owned by the caller, by id | Not declared |
| mail_sources | List stored message ids owned by the caller | Not declared |
| maps_area | Every tile covering a bounding box at a zoom level, as URLs, row by row from the north-west, and how many are already held. What to ask for when you want the map around a place rather than one numbered tile | Not declared |
| maps_tile | The URL for one map tile, by zoom, column and row. Styles: road, outdoor (rights of way and contours), light (a quiet basemap to draw on). Free. Britain only | Not declared |
| markets_convert | Convert an amount from one currency to another — 250 GBP in JPY. Uses European Central Bank reference rates, and takes a past date back to 1999. Crypto converts at the live price through the dollar | Not declared |
| markets_history | Read daily closing prices for a supported instrument over a range of up to 366 days. Missing trading days are omitted. Uses Yahoo Finance | Not declared |

| news_read | Read one news article in full by its id or URL | Read-only |
| news_search | Search indexed and live news for a topic | Read-only |

| notes_delete | Delete one note by title | Destructive |
| notes_get | Read one note by title. Use it when you know the title; notes_list when you do not | Read-only |
| notes_list | List every note the caller has written, with its text | Read-only |
| notify_devices | Whether this account can be reached by notification at all, and on which devices. Worth asking before promising to tell somebody something | Not declared |
| notify_send | Interrupt yourself on your own devices — a phone, a laptop — with the page closed. For the thing that cannot wait until the next time somebody looks. An answer to a question belongs in the thread it was asked in, not here | Not declared |
| places_address | Name the place at a latitude and longitude — the reverse of places_geocode. Use it whenever you have coordinates and need to say where that is | Read-only |
| places_elevation | How high a place is above sea level, in metres and feet. Sampled from a 90-metre global elevation model, so a summit reads a little under its surveyed height | Not declared |
| places_geocode | Resolve a place name or address to coordinates | Not declared |
| places_nearby | List points of interest near a location. Each one says whether it is open right now where that is known, so "is anything open near me" is one call | Read-only |
| places_search | Find places by name or category, optionally near a location. Each one says whether it is open right now where that is known, rather than raw opening-hours text to interpret | Read-only |
| prayer_qibla | Get the qibla — the compass bearing to face for Islamic prayer from a location | Read-only |
| prayer_reflection | Get today's Islamic reflection — a verse of the Quran with its surah, a saying of the Prophet, and a name of Allah | Read-only |
| prayer_saying | Look up a hadith from Sahih al-Bukhari, optionally from a given book | Read-only |
| prayer_search | Search the Quran, the hadith and the names of Allah by meaning — ask a question in plain language rather than naming a reference | Read-only |
| prayer_times | Get today's Islamic prayer times (salah) for a location, and which prayer is next | Read-only |
| prayer_verse | Look up a chapter of the Quran, or one verse within it, by number. Use prayer_search to ask a question instead of naming a reference | Read-only |

| recall_list | List the caller's conversations, most recently active first, with what each is about and where it happened | Read-only |
| recall_search | Search everything the caller has said to an agent and been told, wherever they said it — the browser, email, or the command line. Use it when something was mentioned and you need to find where; notes_get is for a fact somebody wrote down on purpose | Read-only |
| routes_directions | The turn-by-turn route between two places, with the distance for each instruction. Use ETA instead when only the travel time is wanted — this asks the provider for more and costs more | Not declared |
| routes_eta | How long it takes to travel between two places, by road rather than as the crow flies. Can be asked about a future departure, or told when you need to arrive and answer when to leave | Read-only |
| routes_nearest | Given a starting point and several destinations, say which is quickest to reach and put them in order. Each destination is a separate routing lookup, so ask about the places you are actually choosing between rather than a long list | Not declared |
| shell_run | Run a shell command in your account's container sandbox and get back what it wrote. A real shell in a container: pipes, redirection and && all work, the working directory is /work and files there persist between calls. Use it to build, test, run scripts and move files about. A non-zero exit code comes back in the response rather than as an error, so read the output — a failing build is an answer | Not declared |
| shell_write | Put a file in your account's container sandbox, creating any missing directories. The only file operation that is not a shell command, because it is the one a shell is bad at: source is full of quotes and backticks and a heredoc will mangle it. The content arrives as a string and reaches the file without a shell seeing it. To read, list, search or change a file, use the shell — cat, ls, grep and sed are right there | Not declared |
| sms_history | Read the texts this account has sent and received, newest first. Both directions, which is why it is not called an inbox | Not declared |
| sms_number | The number texts are sent from, which numbers are verified as yours, and how many messages are left today | Not declared |
| sms_send | Message somebody from this instance's number, by text or on WhatsApp. A text is charged per 160-character segment; WhatsApp is charged per 24-hour conversation and only reaches somebody who wrote in within the last day. Capped per day either way, and the recipient can stop it with STOP | Destructive |
| sms_source | Read one stored message owned by the caller, by id | Not declared |
| sms_sources | List stored message ids owned by the caller | Not declared |
| sms_verify | Claim a number as your own, so texts arriving from it reach this account. Call it with just the number to have a code texted there, then again with the code | Not declared |
| social_list | Read the latest social posts from the network | Read-only |
| social_search | Search public posts on this instance by keyword. This is the instance's own feed, not the wider internet — use web_search for that | Read-only |
| stream_list | Read what has happened here recently | Read-only |
| tasks_create | Add a task. Assign it to the agent and it can pick the task up itself | Not declared |
| tasks_delete | Remove a task | Destructive |
| tasks_list | List the caller's tasks, open ones first; optionally filtered by state | Read-only |
| tasks_next | The next task assigned to the agent — what to work on now | Not declared |
| tasks_read | Read one task owned by the caller | Read-only |
| tasks_update | Change a task: its state, or the result of doing it | Not declared |
| text_classify | Sort text into one of the labels you give, with a confidence. For routing, triage and moderation. Capped at 30,000 characters | Not declared |
| text_extract | Turn text into JSON matching a schema you give. Pass the fields you want as a JSON schema or a plain description; returns JSON only. Capped at 30,000 characters | Not declared |
| text_summarise | Summarise text into a few sentences. Pass style=bullets for a list, or a sentence count. Capped at 30,000 characters | Not declared |
| text_translate | Translate text into another language, preserving formatting. Capped at 30,000 characters | Not declared |
| transit_arrivals | What is due at a stop and when. Takes a stop name or an id. In London this is live from TfL — buses, tube, DLR, Overground and Elizabeth line. Elsewhere it is the published timetable, and says so | Not declared |
| transit_buses | Where the buses actually are near a point right now — line, where each is heading and how far away, nearest first. England, from the Bus Open Data Service. This is position rather than prediction: it says what is moving, not when it reaches you | Not declared |
| transit_feeds | Which published timetables this instance carries, and which others it could — with the size of each, so an operator can see what switching one on costs. Also names the feeds that look right but whose timetables have run out | Not declared |
| transit_nearby | Bus stops and stations near a point, nearest first, with the id each one is called by. London live from TfL; elsewhere from whichever published timetables this instance has loaded | Read-only |
| transit_status | Which lines are delayed, part-suspended or closed right now, and why. London only | Not declared |
| transit_trains | The live departure or arrival board at a British station, by its three-letter code — KGX, MAN, EDB. Scheduled and expected time, platform, operator and where it is going, plus any disruption notice. From National Rail | Not declared |
| users_find | Look somebody up by username or display name. Use this to turn a name somebody mentioned into an address you can write to | Read-only |
| users_get | One user, by username | Read-only |
| users_list | Everyone on this instance, online first and then newest. Agents are included and marked; an agent account is a user here like any other | Read-only |
| video_list | Read the latest videos from curated channels | Read-only |
| video_read | Read the metadata and description of one video already discovered by this instance. No transcript is available | Read-only |
| video_search | Search YouTube by keyword using this instance's search quota. Results are not restricted to the curated channels | Read-only |
| wallet_address | Your own address on Base, to receive USDC. Created the first time you ask. Funds sent on any other chain land at the same address there and cannot be reached from here | Read-only |
| wallet_balance | What your wallet holds in USDC on Base. Says so plainly when the chain could not be reached, because that is not the same as holding nothing | Read-only |
| weather_air | Air quality at a location right now — AQI, PM2.5, PM10, ozone, nitrogen dioxide, UV index, and pollen where it is counted | Not declared |
| weather_forecast | Get the weather forecast for a location — current conditions, the days ahead, and today's sunrise, sunset and how much daylight is left, which is the fact that decides an afternoon outdoors | Read-only |
| weather_history | What the weather actually was at a location between two dates — average high and low, total rainfall and the extremes. Records run a few days behind today | Not declared |
| weather_lookup | Look up the weather by town or city name | Not declared |
| weather_marine | Sea state at a coastal or offshore point — wave height, period and direction now and for the days ahead, with sea temperature | Not declared |
