MCP Integration

Connect Claude Code agents to external services via Model Context Protocol.

Adding MCP Servers

In your agent's .claude/settings.json:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-filesystem", "/path/to/dir"]
    },
    "github": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-github"],
      "env": { "GITHUB_TOKEN": "ghp_..." }
    }
  }
}

Popular MCP Servers

• filesystem - Read/write local files
• github - Issues, PRs, repos
• postgres - Database queries
• slack - Send/read messages
• brave-search - Web search

Building Custom Servers

import { McpServer } from "@anthropic-ai/mcp";

const server = new McpServer({ name: "my-server" });

server.tool("my_tool", { description: "Does something" }, async (input) => {
  return { result: "done" };
});

server.run();

Best Practices

• Use environment variables for secrets, never hardcode
• Test servers independently before connecting to agents
• Set timeouts on server connections
• Log all MCP calls for debugging
