Tools
| Tool | Description | Behaviour |
|---|---|---|
| billing.plans | The plan catalog (price and quotas per plan) and whether Stripe billing is configured on this host. Anonymous callers get the same answer as tenants. | Not declared |
| host.quickstart | Return the shortest ordered sequence of calls to a working tool of `kind`, with your namespace and a filled-in example already substituted in, plus the current limits and a try_before_call table naming the one dry-run tool for each case. Read-only. Call this before host.tool_publish if you're not sure what a spec should look like. Unauthenticated callers get the signup step first. | Not declared |
| host.redeem | Exchange a signup(handoff: true) handoff_token for the tenant key it was issued for. Single-use: a second redemption fails with handoff_token_redeemed; past its expiry it fails with handoff_token_expired. Unauthenticated -- the token itself is the proof. | Not declared |
| host.state.get | Read one key from this tenant's key-value state namespace. Returns found: false (not an error) if the key was never set. | Not declared |
| host.state.list | List keys (with their current values) in this tenant's key-value state namespace, optionally filtered by prefix. | Not declared |
| host.state.set | Write one key in this tenant's key-value state namespace; value may be any JSON value. Overrun of the plan's state_bytes_max quota fails with state_quota_exceeded and writes nothing. | Not declared |
| host.tool_call | Invoke a tool this tenant has already published, by its local name -- the same real, metered call as calling it directly by its namespaced name (<namespace>.<name>), for a session that has no way to see its own namespaced tool name yet. Unlike host.tool_test, this counts toward host.usage and appears in host.tool_logs. Pass async: true for a tool that needs more than the call deadline: returns {run_id, status: "queued"} immediately instead of running inline -- see host.runs.get/wait. Pass version to pin the call to one of host.tool_history's versions instead of whichever is current. | Not declared |
| host.tool_publish | Publish a tool of a registered kind (chain, echo, http, python, wasm) under this tenant's namespace. Call host.quickstart(kind) first for a filled-in example spec and the full publish-to-call sequence. Python's sandbox API: import mcphost (mcphost.table, mcphost.state, mcphost.docs). Name must match ^[a-z][a-z0-9_]{1,40}$; a rejection names the failing field and a corrected example. Try host.tool_test before a real call. | Not declared |
| host.tool_share | Share one of this tenant's published tools with everyone (visibility: "public") or with a named group this tenant owns (visibility: "group", group: <name>). The tool keeps running in this tenant's own sandbox with this tenant's own secrets; a caller reaches it as <this tenant's namespace>.<name>. | Not declared |
| host.tool_test | Dry-run a published tool by name: writes are rolled back and reported under dry_run, nothing delivered; for the other cases see host.quickstart. | Not declared |
| host.whoami | Return the calling tenant's identity, including key_age_s and key_rotated_at for auditing credential hygiene. | Not declared |
| signup | Create a tenant and receive a bearer key and namespace. Unauthenticated. Recommended: pass handoff: true to receive a short-lived, single-use handoff_token instead of the raw key -- redeem it once with host.redeem to get the key, so a transcript of this call and the redeem call, if it leaks, carries a dead credential. The raw-key path (handoff omitted) stays fully supported. | Not declared |
