RoboPartPicker MCP server

Remote Model Context Protocol server for RoboPartPicker — a catalog of source-linked robotics projects, bills of materials and components.

• Endpoint: https://robopartpicker.com/mcp (Streamable HTTP, no auth for public reads)
• Registry name: com.robopartpicker/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 me which BOM lines are still unresolved." A search_projects call with q=rover returns entries 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 and URDF/robot-description files in each upstream repository. Every line keeps its evidence state — verified, probable, unresolved, unpriced — instead of being silently dropped.
• Prices are observed catalog data, not quotes. Supplier coverage is partial and prices drift.
• Upstream projects keep their own licenses. This server reads and links; it does not relicense anyone's design.
• Software projects, commercial models without manufacturer BOMs, and physical projects without an explicit BOM report distinct honest states rather than guessed parts.
