How to install aegisdb

aegisdb is published on PyPI as aegisdb-mcp, and it depends on mcp. These steps assume it runs as a local stdio server, which is the usual setup.

Check the README. Confirm the start command and note any API keys or environment variables it needs (pass them with -e KEY=value or an env block). You need uv for uvx.

Add it to Claude Code from a terminal:

claude mcp add aegisdb -- uvx aegisdb-mcp

Or add it to Cursor or Claude Desktop in .cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "aegisdb": {
      "command": "uvx",
      "args": [
        "aegisdb-mcp"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm aegisdb and its tools are listed. The install guide covers VS Code and Codex.
