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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "catalog": {
      "type": "http",
      "url": "https://partsgraph.ai/api/mcp"
    }
  }
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
