Tools: search_parts get_part list_categories list_builds check_compatibility compare_parts get_provenance build_bom search fetch view_bom
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. params: query*, category, build, role, limit, project_context |
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. params: id*, project_context |
list_categories | Every category in the catalogue with its part count. params: project_context |
list_builds | The catalogue's reference builds (robot, weather station, plant waterer) with their roles and candidate parts — the starting point for build_bom. params: project_context |
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. params: part_ids*, build_id, project_context |
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. params: a*, b*, project_context |
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. params: id*, code, project_context |
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. params: build_id*, choices, project_context |
search | Search the Partsgraph demo catalogue. Returns result ids for fetch. Alias of search_parts shaped to the search/fetch connector contract. params: query* |
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. params: id* |
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. params: build_id*, choices |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
