rookery-mcp
A free, fully-offline MCP (Model Context Protocol) server that exposes utility tools to any MCP client — Claude, Cursor, Cline, and other coding agents. Written in Python, runs over stdio, zero dependencies, no API keys, no tracking, works offline.
Tools
Tool | What it does |
| UTF-8-safe Base64 encode |
| Base64 decode back to text |
| Generate 1–100 random UUID v4 |
| Validate JSON, pretty-print or minify |
| SHA-256/384/512 hash of text |
| Unix seconds/ms → ISO-8601 UTC |
| Percent-encode / decode |
| snake / kebab / camel / pascal / upper / lower |
| Cryptographically secure random password |
All tools are exposed via the standard MCP methods: tools/list and
tools/call (JSON-RPC 2.0 over stdio).

Requirements
Python 3.9+
Run
python server.pyInstall as a Python package:
uvx --from git+https://github.com/vikash-b5/rookery-mcp -- rookery-mcpAdd to an MCP client
Register python /path/to/server.py (or rookery-mcp) as a stdio MCP
server in your client's config (e.g. Claude Desktop, Cursor, Cline).
Docker
A Dockerfile is included for containerized / registry introspection:
FROM python:3.11-slim
WORKDIR /app
COPY pyproject.toml server.py README.md ./
CMD ["python", "-u", "server.py"]Test
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}' | python server.py
python server.py --list-toolsThe server starts instantly and answers initialize + tools/list
requests, so it passes MCP registry checks (Glama, mcp.so, official
registry).
