claude mcp: Integrating Model Context Protocol Servers

The Model Context Protocol (MCP) allows Claude Code to securely query databases, run custom APIs, read enterprise context, and interface with developer tools seamlessly.

Subcommands Overview

1. Add an MCP Server

# Add a local stdio MCP server
claude mcp add postgresql npx -y @modelcontextprotocol/server-postgres postgresql://localhost/mydb

# Add an HTTP / SSE MCP server
claude mcp add search-server https://mcp.example.com/sse

2. List Installed Servers

claude mcp list

3. Remove an MCP Server

claude mcp remove postgresql

Practical Applications

• Database Queries: Enable Claude to inspect database schemas and run debug queries safely.
• API Testing: Let Claude invoke REST/GraphQL endpoints directly from the terminal.
• Custom Enterprise Tools: Wire up internal ticketing or documentation search tools to your interactive CLI session.
