MCP

Connect Claude, Codex, Gemini, and other MCP-aware assistants to the Source Parts component graph — search parts, price BOMs, and drive PCB workflows.

Getting started

Install locally with uvx/pip or connect the hosted server from claude.ai.

Install Parts MCPRun the Source Parts MCP server locally so any MCP-aware assistant can search parts, price BOMs, and drive PCB workflows.Connect from claude.ai (hosted)Use the hosted Parts MCP server at mcp.source.parts directly from claude.ai — no local install and no API key.

AI assistant setup

Wire Parts MCP into Claude, Claude Code, Cursor, Cline, OpenCode, OpenAI Codex, and Google Gemini.

Claude DesktopRegister Parts MCP with Claude Desktop so you can search components and price BOMs without leaving the conversation.Claude CodeAdd Parts MCP to Claude Code so terminal and IDE sessions can reason over live component data.CursorConnect Parts MCP to Cursor so the editor's AI can search components, price BOMs, and pull datasheets inline.Cline (VS Code)Add Parts MCP to Cline so the VS Code agent can source components and price BOMs from the editor.OpenCodeRegister the hosted Parts MCP server with OpenCode using its remote MCP schema.OpenAI CodexExpose Parts MCP to OpenAI Codex or other MCP-compatible tools so copilots can source validated component data.Google GeminiUse Parts MCP with the Gemini CLI or other Google AI tooling that supports the Model Context Protocol.

Tools

Search and sourcing, datasheets, and BOM matching tools.

Available toolsA map of the Parts MCP tools, grouped by what they do. Tool names use snake_case and return structured JSON.Search & sourcingSearch millions of components, compare distributor pricing, check stock, and find alternates.DatasheetsRead and navigate datasheets without leaving your assistant — chunked reading and section discovery.BOM & matchingUpload BOMs from any supported EDA tool, match lines to catalog parts, and roll up cost and availability.

Manufacturing & design

Fab quotes, DFM, CAD inspection, and schematic repair.

Manufacturing & DFMGet cross-vendor fab quotes and design-for-manufacturing feedback from your assistant.CAD & schematicInspect and edit parametric STEP models and validate KiCad schematics.Schematic repairTriage and repair KiCad schematics — categorize ERC violations and consolidate libraries.

KiCad & local

Local tools for KiCad project discovery and BOM generation.

KiCad integrationLocal tools that discover KiCad projects and generate BOMs directly from schematics.

Security

Authentication, caching, and rate limits.

AuthenticationTwo ways to authenticate: an API key for local use, or OAuth for the hosted connector.CachingParts MCP caches responses locally to keep repeat lookups fast and reduce API calls.Rate limitsParts MCP calls the Source Parts API, which applies per-plan rate limits.
