api record

The Partsgraph demo catalogue: 35 provenance-backed part records and three reference builds. Search parts, read full records with datasheet provenance, check compatibility, and compose validated BOMs. Prices are indicative and dated; availability is never claimed. Filling project_context ranks results for your build. Tool calls are logged anonymously (salted-hash network address, no identity) to power the public demo dashboard.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_builds open 4h ago

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

  • get_part unknown never probed

    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.

    mcp-tool

  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",

    }
  }
}
    arguments 18 lines
  • check_compatibility unknown never probed

    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.

    }
  }
}
    arguments 25 lines
  • compare_parts unknown never probed

    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.

    }
  }
}
    arguments 23 lines
  • get_provenance unknown never probed

    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.

  • view_bom unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
