Tools
| Tool | Description | Behaviour |
|---|---|---|
| compare_listings | Two agents side by side, as markdown: taglines, pricing, API availability, tags — the researched compare facts, honest about unknowns. | Read-only |
| get_best_of | The Published agents in one category, ranked (paid tiers first, then editorial merit), as a markdown answer sheet. | Read-only |
| get_listing | One agent in full, as answer-first markdown: the summary, then every question on the sheet with its answer, the vendor's own words for it and the URL that proves it. Identical to /{slug}.md and to the HTML page. | Read-only |
| list_categories | The Agents Index's taxonomy with live listing counts. | Read-only |
| search_listings | Full-text search over The Agents Index's Published agents. Returns compact records (name, slug, tagline, url). Fetch depth with get_listing. | Read-only |
| send_lead | Send a buyer-intent enquiry (lead) to an agent or a whole category on The Agents Index. Keyless. Requires consent:true, a real name, a permanent (non-disposable) email, a message of at least 20 chars, and a target (listingSlug OR categorySlug). Returns { ok, delivered }. Idempotent by (email, target) within 7 days. Nothing here changes a listing's rank, tier or copy. | Changes data |
| submit_listing | Submit an agent to The Agents Index: url + name (+ optional note). Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request. Identity and email come only from that session. Sign in or explicitly create an account at https://theagentsindex.com/login?next=%2Fsubmit and verify its email before retrying. This tool creates no account and sends no verification email. Returns {httpStatus:201, id, slug, status:'Draft'}; research + the quality gate decide publication. Your own (url, session email) replay within 24h returns httpStatus:200. Track progress at GET /api/submissions/{id}. No session: {httpStatus:401, error:'sign_in_required', message, loginUrl}. Unverified session: {httpStatus:403, error:'email_unverified', message, email, remediation}. Company gate: the account's address, or an address it proved with a code, must be on the submitted website's domain; otherwise {httpStatus:403, error:'domain_unverified', message, domain, remediation} — POST /api/domain-proof/start {url, email} mails a 6-digit code to an address at that domain, POST /api/domain-proof/verify {proofId, code} redeems it, then submit again. Personal mailboxes (gmail, outlook…) never prove a domain. No refusal creates a listing. Validation returns 400; duplicate/claim responses return 409. Read tools remain keyless. | Changes data |
| subscribe_newsletter | Single opt-in subscribe to the The Agents Index digest of new and freshly re-verified agents. Provide an email; returns { ok }. Every issue carries a one-click unsubscribe. | Changes data |
