Tools
| Tool | Description | Behaviour |
|---|---|---|
| fetch | 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). Images, audio and video carry no link and download from the packet's public URL. | Read-only |
| get_agent_commerce_manifest | Read the agent commerce manifest for a listing: price, rights, and how to buy it. | Read-only |
| get_asset | Read a single listing by id. Public projection. | Read-only |
| get_asset_manifest | Read the canonical asset manifest (sha256-stamped). | Read-only |
| get_bundle_manifest | Read the per-asset bundle inventory: every delivered file with role, format, size and content hash, plus counts that name the population each one counted. | Read-only |
| meta_capabilities | Read /v1/meta/capabilities — the authoritative capability state map. | Read-only |
| meta_refinery_support_matrix | 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-only |
| search | Search the Graunt catalog of evaluated data packets. Returns matching packets with their id, title, and public URL. | Read-only |
| search_assets | Search the public catalog of evaluated packets and listings. Returns paginated matches. | Read-only |

- server instructions changed (+"Graunt is the marketplace for agent-ready 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. Check a packet's seller-declared rights (training, redistribution, citation) before you rely on it. This connection does not return a packet's files. The person you work for gets or buys a packet at its url on graunt.com, and the packets their account owns are read through the library connector at https://api.graunt.com/v1/mcp/library: one sign-in with their Graunt account, read-only.")
