Docs MCP server

https://documentation.mailgun.com

Registry code: a4fadb16afdfd5ad

api record

This server exposes documentation tools (API discovery, endpoint details, security schemes, full-text search) through `describe-tools` and `execute`:

- `describe-tools` returns the exact TypeScript signatures of the sandbox tools.

_ is it live, free and safe measured by this hub
Is Docs MCP server live?
Yes — it answered the hub's last check (checked 26m ago). It answered 99% of checks over the last 30 days.
Is Docs MCP server free to use?
Yes — the hub reached it with no key and no payment.
What tools does Docs MCP server have?
3 tools: execute, submit-feedback, describe-tools.
Is Docs MCP server 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.

_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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.

    Get the exact TypeScript signatures of the sandbox tools available to `execute`. Analyze the user request first, then pass `tools` with only the tool names the request needs (every name is listed in this input schema / description); omit `tools` only when you cannot tell which tools apply. Always call this before your first `execute` and never guess signatures. Request every tool the task may need in ONE call instead of calling this repeatedly.

  • execute reads unknown never probed

    Run JavaScript in a sandbox against the tools for the documentation at https://documentation.mailgun.com. The tools are on the global `tools` object. The only extra global is `tools` - there is no `fetch`, `console`, `setTimeout`, `require`, or Node.js API; all I/O goes through `tools`. Workflow - minimize round-trips; one `describe-tools` call plus one `execute` call covers most requests: 1. Analyze the request and decide which sandbox tools it needs. 2. Call `describe-tools` with those names to get their exact TypeScript signatures - inputs, result shapes, and a worked example. NEVER call `execute` with guessed method names, parameter names, enum values, or result field names: read fields off the declared return types, not from assumptions. 3. Batch everything into a SINGLE script: chain tool calls, pass one call's output into the next, process results in plain JavaScript, and `return` only what the request needs. Available tools (exact signatures come from `describe-tools`): - listApis — Lists the APIs documented in this project - getEndpoints — Get all endpoints for a specific API.

_ try it over mcp 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 a4fadb16afdfd5ad.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a4fadb16afdfd5ad/claim. Over MCP: the claim_endpoint tool.

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 knowoff the mcp door
card completeness
70%

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.
