agents.txt
Registry code: 49203a3a8e9286b1
This server exposes the agents.txt v1.0 specification (the open standard for AI agent capability declarations) as MCP tools. Use it when you need to:

- Is agents.txt live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
- Is agents.txt free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does agents.txt have?
- 6 tools: parse_agents_txt, validate_agents_json, validate_agents_txt, audit_site, get_skill, get_spec.
- Is agents.txt 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.
get_spec reads open 1h ago
Get the agents.txt standard spec (v1.0) from the live site. Use "all" for the full spec or a section name to filter: overview, format, discovery, payments, authorization, mcp, skills, json, examples, versioning, security.

Parse the text content of an agents.txt file into a structured JSON object matching the agents.json schema shape.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "content" ], "properties": { "content": { "type": "string", "description": "Raw text content of an agents.txt file" } } }arguments 13 linesvalidate_agents_json reads unknown 15h ago
Validate an agents.json object against the spec schema. Returns errors (schema violations) and warnings.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "content" ], "properties": { "content": { "type": "string", "description": "Raw JSON string content of an agents.json file" } } }arguments 13 linesvalidate_agents_txt reads unknown 15h ago
Validate the text content of an agents.txt file against the spec rules. Returns errors (spec violations) and warnings (unknown identifiers).
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "content" ], "properties": { "content": { "type": "string", "description": "Raw text content of an agents.txt file" } } }arguments 13 linesaudit_site reads unknown 1h ago
Fetch and audit a live site for agents.txt spec compliance. Validates agents.txt and agents.json against the directives in §3, §6–§11, the JSON schema in §5, and the §4.5 HTTP serving requirements; cross-checks the two files for consistency. Scope is the agents.txt spec only — robots.txt, sitemap.xml, and llms.txt are governed by other specs and are not audited here.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "url" ], "properties": { "url": { "type": "string", "description": "Site origin or URL to audit (e.g. \"https://example.com\" or \"example.com\")" } } }arguments 13 linesget_skill reads unknown 1h ago
Fetch a skill package by name. Returns the full SKILL.md markdown content. Skill names come from the agents.json skills list; use "list" to see available skills. Companion files (REFERENCE.md, scripts) inside the same skill folder are not fetched here. The agent loads them on demand via the links inside SKILL.md.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id49203a3a8e9286b1.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/49203a3a8e9286b1/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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
