Overview

AI-generated overview

Lets an assistant search electronic components, compare distributor prices, check stock, and process BOMs from KiCad, Altium and other EDA tools.

What you can do
  • Search parts and read details, pricing across distributors, and real-time availability
  • Find alternative or drop-in replacement parts for obsolete components
  • Process BOM files from KiCad, Altium, Fusion 360, Eagle, PADS and Protel 99, and match components to parts with confidence scoring
  • Discover local KiCad projects and generate a BOM from a KiCad schematic via the KiCad CLI
  • Cache responses locally for faster repeat lookups
When to use it
Useful when sourcing components for a PCB design, costing a BOM for a production quantity, checking stock before ordering, or finding substitutes for parts that are obsolete or unavailable.
Requirements
Either the remote endpoint with OAuth sign-in, or a local run via uvx or pip on Python 3.10+ with a Source Parts API key in SOURCE_PARTS_API_KEY. Optional settings cover the API URL, KiCad search paths and cache directory. Network access to the Source Parts API is needed; KiCad CLI features require KiCad installed locally.
Before you install
The local package requires a Source Parts API key, which is stored in the client configuration. BOM files and part queries are sent to the Source Parts API for matching, pricing and inventory checks. KiCad tools read local project files and schematics. Pricing and stock figures come from third-party distributors and may be stale or incomplete.

Installation

In SourceWeft

  1. Open Source Parts in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.SourceParts%2Fparts-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Parts MCP

A Model Context Protocol (MCP) server for sourcing electronic parts with multi-EDA integration.

Overview

Parts MCP enables AI assistants to search for electronic components, compare prices, check availability, and process BOMs from popular EDA tools. It provides a unified interface for component sourcing workflows powered by the Source Parts API.

Supported EDA Tools

ToolBOM FormatStatus
KiCadCSV, XMLFull support + CLI integration
Altium DesignerCSV, XLSFull support
Autodesk Fusion 360CSVFull support
EagleCSV, BRDFull support
PADSCSV, ASCFull support
Protel 99CSVFull support

Features

  • Universal Parts Search: Search millions of parts via Source Parts API
  • Multi-EDA BOM Processing: Import BOMs from KiCad, Altium, Fusion360, Eagle, PADS, Protel99
  • Component Matching: AI-powered matching with confidence scoring
  • Price Comparison: Compare prices across distributors
  • Availability Check: Real-time inventory levels
  • Alternative Parts: Find drop-in replacements and functional equivalents
  • KiCad CLI Integration: Generate BOMs directly from schematics
  • Local Caching: Fast responses with intelligent caching

Installation

Quick Start (Recommended)

bash
uvx parts-mcp

No install needed -- uvx runs it directly from PyPI in an isolated environment.

With pip

bash
pip install parts-mcp

From Source

bash
git clone https://github.com/SourceParts/parts-mcp.gitcd parts-mcppip install -e .

Requirements

Configuration

Create a .env file or set environment variables:

bash
# RequiredSOURCE_PARTS_API_KEY=your_api_key_here
# OptionalSOURCE_PARTS_API_URL=https://api.source.parts/v1KICAD_SEARCH_PATHS=/path/to/kicad/projectsPARTS_CACHE_DIR=~/.cache/parts-mcpCACHE_EXPIRY_HOURS=24

Claude Desktop Integration

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

json
{  "mcpServers": {    "parts": {      "command": "uvx",      "args": ["parts-mcp"],      "env": {        "SOURCE_PARTS_API_KEY": "your_api_key_here"      }    }  }}

If installed from source:

json
{  "mcpServers": {    "parts": {      "command": "/path/to/python",      "args": ["/path/to/parts-mcp/main.py"],      "env": {        "SOURCE_PARTS_API_KEY": "your_api_key_here"      }    }  }}

After adding the configuration, restart Claude Desktop.

Claude.ai Integration (Remote)

Connect directly from claude.ai without any local installation:

  1. Open claude.ai in your browser
  2. Go to Settings > Connectors
  3. Click Add custom connector
  4. Enter the URL: https://mcp.source.parts/
  5. Complete the OAuth sign-in when prompted
  6. Start using Parts tools in any conversation

No API key needed -- authentication is handled via OAuth.

Claude Code Integration

Add to your Claude Code MCP settings (~/.claude/settings.json):

json
{  "mcpServers": {    "parts": {      "command": "uvx",      "args": ["parts-mcp"],      "env": {        "SOURCE_PARTS_API_KEY": "your_api_key_here"      }    }  }}

Or run directly:

bash
claude --mcp-server "python -m parts_mcp"

Architecture

Parts MCP follows a thin client architecture:

Local (MCP):

  • KiCad CLI operations
  • Project discovery
  • Response caching
  • BOM file parsing

Server (Source Parts API):

  • Component matching
  • Price aggregation
  • Inventory checking
  • Alternative search

Development

bash
# Install dev dependenciespip install -e ".[dev]"
# Run testspytest
# Run with debug loggingDEBUG=1 python main.py
