## Tools (as reported by the server, not verified)

- `search\_parts`: Full-text search over the demo catalogue's provenance-backed part records. Filter by category, build or role. Every attribute returned was corroborated against the manufacturer datasheet or vendor page.
- `get\_part`: The complete canonical record for one part: every attribute with its provenance \(source, page, verbatim quote, file hash\), vendors with dated indicative prices, and datasheet links.
- `list\_categories`: Every category in the catalogue with its part count.
- `list\_builds`: The catalogue's reference builds \(robot, weather station, plant waterer\) with their roles and candidate parts — the starting point for build\_bom.
- `check\_compatibility`: Evaluates a part set against the build's engineering constraints — supply windows, stall vs peak current, shaft/wheel fit, interfaces, solar chain — with a reasoned verdict per check. Every number cited is a corroborated attribute.
- `compare\_parts`: Aligned attribute-by-attribute comparison of two catalogue parts. Absence means the sources did not state a value — never that the part lacks the property.
- `get\_provenance`: The receipt behind a stated value: the verbatim source quote, the page, the extraction method, and the sha-256 of the exact file it was read from — plus a ready-made citation line. Omit code for every attribute's receipt.
- `build\_bom`: Composes a complete BOM for a reference build — quantities, dated indicative prices, per-line rationale, a compatibility verdict for the chosen set, and a CSV export. Override any role with choices.
- `search`: Search the Partsgraph demo catalogue. Returns result ids for fetch. Alias of search\_parts shaped to the search/fetch connector contract.
- `fetch`: Fetch the full provenance-backed record for a search result id as a citable document. Alias of get\_part shaped to the search/fetch connector contract.
- `view\_bom`: Composes the BOM for a reference build and renders it as an interactive view in clients that support MCP Apps. Same data as build\_bom.
