RoboPartPicker MCP server

Remote Model Context Protocol server forRoboPartPicker — a catalog of source-linked roboticsprojects, bills of materials and components.

Endpoint: https://robopartpicker.com/mcp (Streamable HTTP, no auth for public reads)
Registry name: com.robopartpicker/robopartpicker
Product repository: brainbook0/robopartpicker
Discovery: https://robopartpicker.com/.well-known/mcp.json
Server card: https://robopartpicker.com/.well-known/mcp/server-card.json
OpenAPI: https://robopartpicker.com/openapi.json

This repository holds the registry manifest and client configuration for the hosted server.The server itself runs on Cloudflare Workers at robopartpicker.com.

Tools

Tool	What it does
`search_projects`	Search open robotics projects by keyword, category or kind.
`get_project`	Fetch one project with its source repo, license, files and BOM summary.
`search_components`	Search the technical component catalog by name, category or maker.
`compare_components`	Compare two to four components. Same category never implies verified drop-in compatibility.
`validate_rpps`	Validate a Robotics Project Package Specification (RPPS) document.

A healthy response reports serverInfo.name = RoboPartPicker and a tools capability.

Example

Ask an agent: "Find an open 6-axis robot arm project with a bill of materials, and tell mewhich BOM lines are still unresolved." A search_projects call with q=rover returnsentries such as:

{
  "slug": "nasa-jpl-open-source-rover",
  "name": "NASA JPL Open Source Rover",
  "license": "Apache-2.0"
}

What the data is, honestly

BOM lines are derived from explicit BOM files, documentation, CAD metadata andURDF/robot-description files in each upstream repository. Every line keeps its evidencestate — verified, probable, unresolved, unpriced — instead of being silently dropped.
Prices are observed catalog data, not quotes. Supplier coverage is partial and pricesdrift.
Upstream projects keep their own licenses. This server reads and links; it does notrelicense anyone's design.
Software projects, commercial models without manufacturer BOMs, and physical projectswithout an explicit BOM report distinct honest states rather than guessed parts.

License

The contents of this repository (manifest, documentation, configuration) are MIT licensed.Robotics project data returned by the API remains subject to each upstream project's ownlicense.
