maxAtoms

MCP tool from Pubchem MCP Server by cyanheads

/maxBonds bound the atom/bond preview and includeRawSdf opts into a large raw SDF past the safe line cap; atomCount/bondCount always report the totals and any capping is disclosed

How to use it

Project documentation lists maxAtoms for the Pubchem MCP Server MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Install Pubchem MCP Server

$docker run -p 3010:3010 pubchem-mcp-server
