SheetsData

octoco-ltd/sheetsdata-mcp

Gives Claude structured access to electronic component datasheets without touching PDFs. You can search parts, pull pinouts and electrical specs on demand, validate design parameters against abs max ratings, compare alternatives, and even upload private datasheets for extraction. The compare_parts and check_design_fit tools are especially useful during component selection when you need to verify operating conditions or find drop-in replacements. Ships with prompts for common workflows like BOM review and thermal analysis. Supports OAuth and API key auth, works over stdio or HTTP. Built for hardware engineers who want agents to reason about real component data instead of hallucinating specs or choking on 200-page PDFs.

Install

From registry metadata

$ npx add-mcp https://mcp.sheetsdata.com/mcp --name sheetsdata-mcp

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http sheetsdata-mcp https://mcp.sheetsdata.com/mcp

Readme

SheetsData MCP

Electronic component datasheets for AI agents — pinouts, specs, package info and design checks from manufacturer PDFs.

SheetsData is a hosted MCP server. Your agent finds parts across JLCPCB, Mouser and DigiKey, reads any section of a part's datasheet as text and tables, compares parts, checks a BOM, and checks your operating conditions against the datasheet's ratings. The agent never sees a PDF, and you don't have to find or paste one.
