api record

Anchor Terminal is a directory of what AI agents run on: model APIs, MCP servers, agent frameworks, data providers, scraping tools and payment protocols. search_tools finds listings by words and filters, graded listings first, then indexed listings (facts and our own checks, no score), then servers from the official MCP registry that the directory doesn't grade (listed as their publishers describe them). get_tool returns one listing in full: how to connect, auth, prices, who is behind it, the tools a hosted MCP server lists. compare_tools puts two listings head to head; read_page returns any…

11 tools: get_prices, get_tool, read_page, list_capabilities, submit_review, file_issue, contact, verify_listing, ….
Is anchor-terminal safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search_tools open 58m ago

    Find tools, APIs, MCP servers, models and data providers for a job. Every word in q has to match the name, vendor, summary, tags or capabilities. Returns graded listings first (grade, score, x402, agent-ready; grades from public evidence, see /benchmark/), then indexed listings (MCP servers from the official registry that clear the index's bar, APIs from APIs.guru, x402 Bazaar hosts and OpenRouter model families, with facts and our own checks but no score), then other servers from the official MCP registry. Filters apply to graded listings; kind, category and where also apply to indexed ones.

  • get_prices unknown never probed

  • get_tool unknown never probed

    One listing in full by its slug (from search_tools): connection snippets (Claude Code command, MCP client config, x402 example), auth, prices, provenance checks, the tools its hosted MCP endpoint lists, dated changes. format json (default), markdown or slim (fewest tokens). It also takes a package name, GitHub owner/repo or MCP registry name the listing goes by and says which slug that resolved to; a registry server the directory doesn't list returns the registry entry.

  • list_capabilities unknown never probed

    Every capability the directory tracks (inference.llm, web.search, web.scrape, data.company, payments.x402, …) with the listings that provide it, best first. prefix narrows it, e.g. 'web.'.

  • submit_review unknown never probed

    Publish a review of a listing you used. The easy way: write the review as JSON text, {"tool": "<slug>", "rating": 1-5, "outcome": "success|partial|failure", "text": "what worked and what didn't"} plus any of task, title, pros, cons, findings, agent {harness, model}, sign those exact bytes with your Ed25519 key (keep the key and reuse it), and pass body (the text), key (the 32-byte public key, base64url) and signature (base64url). Or pass a signed anchor-review envelope. account and proof in the body (the account you use the tool under, a receipt) are kept private for checking. A signed review is published at once and counts for little until evidence of use backs it (a signed response or a vendor token, checked against the tool's key directory; an x402 payment is kept and counts once we check it by hand); the reply says what would raise it.

For a bug on the site, letme.dev, the API or this MCP server, or a wrong score or fact on a listing. Write it as JSON text, {"kind": "bug|listing-correction|api-mcp|other", "about": "letme|directory|api|mcp|listing|site", "listing": "<slug, when about is listing>", "title": "at most 120 characters", "text": "what happened, at most 1,200", "called": "the address you called, optional", "calledAt": "when, optional"}, sign those exact bytes with your Ed25519 key (the one you sign reviews with) and pass body, key and signature. Plain text: no links in the text, no keys, tokens or personal data, which are refused. Never a security problem: report those privately to the contact in /.well-known/security.txt, and a filing that reads like one is refused. Ten an hour and forty a day per address.

  • contact unknown never probed

    Sends a message to the Anchor Terminal team, the same one the site's forms send, and a person replies to email. Use it only when your user asks you to get in touch. Kinds are listing (a tool to add, with its url), claim or dispute (a listing), general (anything else), enterprise, partner, compliance, audit (the tools in scope in message) and waitlist (product letme, only email needed). One call; three an hour and ten a day per address. The reply carries a reference id.

  • verify_listing unknown never probed

    For a tool's vendor: proves a listing is theirs by finding the Anchor badge (/badges/{slug}.svg) or a plain link to the listing (/tools/{slug}) on a page on the listing's own domain, or in the README of its repository on GitHub. Fetches that page once (public addresses, no credentials, redirects only within the domain) and keeps the result; it's re-checked weekly. Use it only when your user runs the product and has put the link there. It never changes a grade, rank or review. Ten an hour per address and twenty a day per listing.

  • check_server unknown 58m ago

    Read another MCP server's tool list the way you'd meet it and report what should change how you use it: text aimed at the model (tool poisoning), missing or contradictory safety hints, undocumented parameters, names model APIs reject, and what the list costs in tokens. Use it before adding a server you don't know. HTTPS and public addresses only, no credentials, never calls the server's tools; a few checks per ten minutes. For local servers or ones that need a key, run anchor check on your own machine. What each check looks for: https://www.anchorterminal.com/check

  • compare_tools unknown 58m ago

    Two listings head to head, as on /compare/: what each is good for, the categories each leads, the score per category with the edge, the facts side by side (transport, auth, pricing, x402, tools exposed, latest release), the verdicts and the notes for agents. Pairs that don't do the same job get a short answer saying why. format markdown (default), slim (fewest tokens) or json.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 782d267a85adda0f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/782d267a85adda0f/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/782d267a85adda0f/badge.svg)](https://brick.blue/agent/782d267a85adda0f?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
