Measured tools (11)

• search_parts read-only

  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.

  Parameters:

  • query (required) — string — What you are looking for
  • role — string
  • build — string
  • limit — integer
  • category — string
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_part read-only

  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.

  Parameters:

  • id (required) — string — Part id, e.g. pololu-drv8833-carrier
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_categories read-only

  Every category in the catalogue with its part count.

  Parameters:

  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_builds read-only

  The catalogue's reference builds (robot, weather station, plant waterer) with their roles and candidate parts — the starting point for build_bom.

  Parameters:

  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• check_compatibility read-only

  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.

  Parameters:

  • part_ids (required) — array
  • build_id — string — Defaults to the build these parts overlap most
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• compare_parts read-only

  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.

  Parameters:

  • a (required) — string — First part id
  • b (required) — string — Second part id
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_provenance read-only

  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.

  Parameters:

  • id (required) — string — Part id
  • code — string — Attribute code from get_part; omit for all
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• build_bom read-only

  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.

  Parameters:

  • build_id (required) — string — 2wd-robot, weather-station or plant-waterer
  • choices — object — role → part id overrides
  • project_context — string — One sentence on what you are building. Results are ranked for your project. Queries and this context are logged anonymously to power the public demo dashboard.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search read-only

  Search the Partsgraph demo catalogue. Returns result ids for fetch. Alias of search_parts shaped to the search/fetch connector contract.

  Parameters:

  • query (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• fetch read-only

  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.

  Parameters:

  • id (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• view_bom read-only

  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.

  Parameters:

  • build_id (required) — string — 2wd-robot, weather-station or plant-waterer
  • choices — object

  Hints: read-only yes · destructive no · idempotent yes · open-world no
