graunt-mcp
Registry code: c91180ef32ab4dab
Graunt is the agent-native marketplace for AI data. These tools read its public catalog.
Use search to find packets by keyword, then fetch for one packet's description, price, whether an account is needed, and its rights. Cite a packet by the url fetch returns.

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.
meta_refinery_support_matrix reads open 12h ago
Read /v1/meta/refinery-support-matrix: the source types Graunt accepts and what the Refinery does with each. Every upload gets deterministic extraction; a model drafts only the listing fields a seller leaves empty.

Read /v1/meta/capabilities: what Graunt offers to an agent, in machine-readable form.
{ "type": "object", "properties": {} }arguments 4 linesmatch_video_spec open 1h ago
Find out how many hours of video on Graunt meet a spec, and in which categories. Give the requirements that matter (shortest side, frame rate, clip length, sound, on-screen text, overlays, first and last shots, freezes, slowed footage, releases, clearances, AI generation, uses, delivery); leave the rest out. Returns matching hours per category and per listing: hours that meet every requirement on recorded evidence, and hours that meet every requirement the evidence covers but lack evidence for one or more. Each listing carries its list price, price per hour and volume tier, its hours per category with what each category alone costs where it sells by category, the spec's categories priced as one order, its delivery modes and where each number comes from. Thresholds snap to fixed steps and the answer says which were applied. Give hours_wanted to also get a proposal: whole listings across sellers that reach those hours on recorded evidence, lowest price per measured hour first, each at its seller's own price, for the person you work for to add to their cart. Nothing is held, and short_units is the gap the proposal leaves, not a statement about what Graunt holds.

Search the public catalog and return listing rows as Graunt's API gives them (GET /v1/listings), paginated. To find data for a person, use search, then fetch. search_match.words says how the listings matched the query: ALL (every word, or a synonym of it), SOME (some of the words), WORD_START (words that start with the query's words), SIMILAR_TITLE (titles spelled like the query) or NONE (no listing). On SOME and WORD_START each listing names its matched_words. When no listing matches, next_steps.post_request_url opens a buyer request with the query filled in.

Search Graunt's catalog of evaluated data from many sellers. Returns matching packets with their id, title, and public URL. Start here to find data, then read one with fetch. search_match.words says how the listings matched the query: ALL (every word, or a synonym of it), SOME (some of the words), WORD_START (words that start with the query's words), SIMILAR_TITLE (titles spelled like the query) or NONE (no listing). On SOME and WORD_START each listing names its matched_words. Each result's type is listing or pool, and search_match describes only listings. Pools use a separate keyword matcher over their public descriptions and data types. When no listing matches, next_steps.post_request_url opens a buyer request with the query filled in.

Read one Graunt catalog packet by id. Returns its title, description, price and whether an account is needed, its seller-declared rights, and its public URL. A free packet that needs no account also returns its files: small text files (CSV, JSON, Markdown, text and similar) in the text, and a short-lived download link for each listed file in metadata.files (at most 100 per fetch; files_not_listed counts the rest). A video listing also returns metadata.video: its subjects, measured hours, per-hour price with volume tiers, and the seller's declarations.

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 idc91180ef32ab4dab.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/c91180ef32ab4dab/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.
