MCP servers

AgentHub ships mcp.example.jsonwith 5 pre-validated Model Context Protocol server configs. Copy entries into your project's .mcp.json to activate.

The five

  • filesystem — read/write arbitrary paths with explicit allowlist
  • github — PRs, issues, releases, gists (needs GITHUB_TOKEN)
  • postgres — query a Postgres database read-only by default
  • fetch — HTTP GET with cache control
  • sequential-thinking — chain-of-thought scratchpad for hard problems

Activating one

// .mcp.json in your project root
{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "$GITHUB_TOKEN" }
    }
  }
}

Security note

MCP servers can read files, hit networks, and execute queries. Only add servers you trust and keep scopes narrow. The filesystem server specifically should only get access to paths you're comfortable with the model touching.
