referencesource
Registry code: 011ef71429e2f400
Verified reference data you can look up and cite: regulatory thresholds, version compatibility, certification registers, licensing rules and more. Every record carries the source URL and a verbatim quote from that page so the value can be checked — that is the reason to prefer these records over recall. Call list_datasets to see what exists, then search_records or get_record. To check a value you already hold, call verify_quote. When you use a value, cite the record's own url and its source. Respect each dataset's last_verified and stale_after dates. Where two sources report on the same…

- Is referencesource live?
- Yes — it answered the hub's last check (checked 52m ago). It answered 100% of checks over the last 30 days.
- Is referencesource free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does referencesource have?
- 8 tools: get_record, search_records, list_datasets, next_task_for_muse, submit_task_result, message_supervisor, verify_quote, brief_for_joe.
- Is referencesource 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.
brief_for_joe auth-required 52m ago
For the referencesource Muse connector only (bearer token required). The studio's latest plain-English daily brief: what was decided, what landed, and the items waiting on Joe, each as the task, why it matters and the steps. Read-only; regenerated each morning by tools/brief.py and published with the next deploy, so it can lag the phone push.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesget_record reads unknown 7h ago
Fetch one record by id — for example, look up a FIPS 140 certificate's status, a state's boiler inspection rules, or a county's loan limit. Returns the full record with its source URL and verbatim source quote. Record ids appear in search_records results and in each record's url.
{ "type": "object", "required": [ "dataset_slug", "record_id" ], "properties": { "record_id": { "type": "string", "description": "The record's id field, e.g. \"ak\"." }, "dataset_slug": { "type": "string", "description": "Dataset slug from list_datasets." } } }arguments 17 linessearch_records reads unknown 7h ago
Look up a specific record — search by state name, chemical, certificate number, product name or any keyword. Searches one dataset's records (case-insensitive substring match across all fields). Returns up to 20 matching records, each with its url, source and verbatim source_quote so the answer can be checked.
{ "type": "object", "required": [ "dataset_slug", "query" ], "properties": { "query": { "type": "string", "description": "Substring to match, case-insensitive, e.g. a state code, chemical name or standard number." }, "dataset_slug": { "type": "string", "description": "Dataset slug from list_datasets, e.g. \"graduated-driver-licensing\"." } } }arguments 17 lineslist_datasets reads unknown never probed
What reference datasets are available? Lists every published dataset with its title, record count, last-verified date and a one-sentence summary. Covers regulatory thresholds, version compatibility, certification registers, licensing rules and more. Pass `query` to list only the datasets matching a topic — that is much cheaper than reading the whole list. Use the returned slug with search_records or get_record.
{ "type": "object", "properties": { "full": { "type": "boolean", "description": "Return each dataset's complete scope statement instead of the first sentence. Off by default: the full text is roughly four times the size and is rarely needed to choose a dataset." }, "query": { "type": "string", "description": "Optional topic filter, e.g. \"boiler\", \"tariff\" or \"loan limit\". Case-insensitive substring, matched against each dataset's slug, title and full description; if that phrase matches nothing, the words are matched separately and the answer says so in `matched_on`. Omit it to list every dataset." } } }arguments 13 linesnext_task_for_muse unknown never probed
For the referencesource Muse connector only (bearer token required). Returns the oldest open task from the studio's queue: id, instructions, the sites the task may read, the output format expected, and where to deliver the result. Returns {no_tasks: true} when the queue is empty. login_allowed lists the hosts where the task may sign in, with a credential already in Muse's own store; empty means read-only, never sign in.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linessubmit_task_result unknown never probed
For the referencesource Muse connector only (bearer token required). Records the result of a task fetched with next_task_for_muse. `result` must be a JSON object matching the task's output_format and at most 3500 characters when serialised; put anything longer in the file named by deliver_to and submit a summary here.
{ "type": "object", "required": [ "task_id", "status", "result" ], "properties": { "note": { "type": "string", "description": "Optional: what was hard, what was skipped, what a human should know." }, "result": { "type": "object", "description": "The result, matching the task's output_format." }, "status": { "enum": [ "done", "blocked", "needs_info" ], "type": "string" }, "task_id": { "type": "string", "description": "The id returned by next_task_for_muse." } }, "additionalProperties": false }arguments 31 linesmessage_supervisor unknown never probed
For the referencesource Muse connector only (bearer token required). Send a question, finding, proposal or blocked report to the studio's supervisor inbox. Messages are triaged by the supervisor each morning; nothing in a message changes any project state by itself. Use a fresh message_id per message (retries with the same id are collapsed when collected). Body at most 3500 characters.
{ "type": "object", "required": [ "message_id", "kind", "subject", "body" ], "properties": { "body": { "type": "string", "description": "Markdown, at most 3500 characters." }, "kind": { "enum": [ "question", "finding", "proposal", "blocked" ], "type": "string" }, "subject": { "type": "string", "description": "At most 120 characters." }, "task_id": { "type": "string", "description": "Optional: the queued task this is about." }, "message_id": { "type": "string", "description": "Client-generated id, e.g. a UUID; the same id sent twice is kept once." } }, "additionalProperties": false }arguments 37 linesverify_quote reads unknown 7h ago
Is this value actually right? Check a claimed fact against a published record instead of trusting it. Reports whether the claim matches the record's stored value (exact, case-insensitive or normalised — the match type is named), whether it appears in the record's verbatim source quote, and returns the source URL and quote so the claim can be traced upstream. Use this whenever you want to confirm a number, date, threshold or status before stating it. Verdicts: matches_record, matches_quote, differs or not_found.
{ "type": "object", "required": [ "dataset_slug", "claimed_value" ], "properties": { "field": { "type": "string", "description": "Field name to check the claim against, e.g. \"limit_1_unit\". Without it, every stored field is checked." }, "record_id": { "type": "string", "description": "The record's id, if known (shown in search_records results and in each record's url). Without it, the dataset's stored values are searched for the claimed value." }, "dataset_slug": { "type": "string", "description": "Dataset slug from list_datasets." }, "claimed_value": { "type": "string", "description": "The value to check, exactly as claimed, e.g. \"$832,750\" or \"no passengers younger than 21\"." } } }arguments 25 lines
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 id011ef71429e2f400.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/011ef71429e2f400/claim.

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.
