  • submit_listingchangeddescription
    before

    Submit an agent to The Agents Index: the url alone; we write its name and description from its own pages. Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request, or an agent key the account made at https://theagentsindex.com/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. 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.

    The Published agents in one category, in the order its category page prints (ranked by what we can confirm: a public price, an API and docs, independent sources, stated limits), as a markdown answer sheet. Payment never moves a row.

  • my_listingsadded

    What the The Agents Index owner dashboard shows about the listings an account owns: each one's status (in review with the expected date, accepted and going live on a day, live, or not accepted with the reason), the listing as it shows, 30 days of real numbers with the 30 before, where AI answers named the product or cited its page, and what it can buy here at this site's prices. Only for the account itself: send its session Cookie header, or its agent key with "Read your listings" as Authorization: Bearer. Same answer as GET https://theagentsindex.com/api/owner/listings. Read-only: corrections go through the dashboard's request form.

Tools (9)

compare_listingsread-onlyTwo agents side by side, as markdown: taglines, pricing, API availability, tags — the researched compare facts, honest about unknowns.
get_best_ofread-onlyThe Published agents in one category, in the order its category page prints (ranked by what we can confirm: a public price, an API and docs, independent sources, stated limits), as a markdown answer sheet. Payment never moves a row.
get_listingread-onlyOne 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.
list_categoriesread-onlyThe Agents Index's taxonomy with live listing counts.
my_listingsread-onlyWhat the The Agents Index owner dashboard shows about the listings an account owns: each one's status (in review with the expected date, accepted and going live on a day, live, or not accepted with the reason), the listing as it shows, 30 days of real numbers with the 30 before, where AI answers named the product or cited its page, and what it can buy here at this site's prices. Only for the account itself: send its session Cookie header, or its agent key with "Read your listings" as Authorization: Bearer. Same answer as GET https://theagentsindex.com/api/owner/listings. Read-only: corrections go through the dashboard's request form.
search_listingsread-onlyFull-text search over The Agents Index's Published agents. Returns compact records (name, slug, tagline, url). Fetch depth with get_listing.
send_leadSend 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.
submit_listingSubmit an agent to The Agents Index: the url alone; we write its name and description from its own pages. Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request, or an agent key the account made at https://theagentsindex.com/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. 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. The fit check starts at once and usually answers within a minute: poll GET https://theagentsindex.com/api/submissions/{id} and wait the Retry-After seconds it sends while fit is "checking". fit then reads "accepted" (it goes live, and the account is mailed), "rejected" (mailed with the reason) or "undecided" (a person looks within 2 days).

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.
subscribe_newsletterSingle 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.
