Pubchem Mcp Server

Pubchem MCP Server is an open-source MCP (Model Context Protocol) server designed to make the PubChem chemical database accessible to AI assistants like Claude, Cursor, and other MCP-compatible clients. It exposes eight ready-to-use tools for searching and managing chemical data—let users search for compounds, retrieve detailed molecular properties, fetch chemical images, obtain safety/hazard data, bioactivity results, cross-references (xrefs), and summarized entity information for compounds, proteins, genes, and assays. Ideal for researchers, bioinformaticians, cheminformaticians, LLM-powered assistants, and scientific developers needing chemical data programmatically or conversationally.
