dauphin-notion-mcp: Command for Claude Code

Sync notion_mcp.py from the upstream repo at ../dauphin into this project.

Background

This repo is a standalone Notion MCP server extracted from the ../dauphin monorepo. The only functional difference is secrets management: upstream discovers a secrets/notion_token file by walking directories, while this project takes --token-file <path> as a required CLI argument. Everything else should match upstream.

Steps

1. Copy source and test files

Copy both files from upstream, overwriting the local versions:

• ../dauphin/src/notion_mcp.py → src/notion_mcp.py
• ../dauphin/tests/test_notion_mcp.py → tests/test_notion_mcp.py

2. Restore --token-file secrets management

After copying, the file will have upstream's secrets-dir approach. Replace it with this project's --token-file approach. There are four specific changes:

a) Module docstring — Change:

Credentials: Reads token from secrets/notion_token file.

to:

Token: Passed via --token-file <path> CLI argument at startup.

b) Replace _SERVER_VERSION block — The upstream version uses subprocess + git rev-parse to get a git hash. Replace the entire _SERVER_VERSION block (and remove the import subprocess line) with:

# Server version from package metadata (set in pyproject.toml)
try:
    from importlib.metadata import version as _pkg_version
    _SERVER_VERSION = f"v{_pkg_version('dauphin-notion-mcp')}"
except Exception:
    _SERVER_VERSION = "unknown"

c) Remove _find_secrets_dir() and _load_notion_token() — Delete both functions entirely (they're between the _notion_token global and _get_token()).

d) Replace _get_token() — Replace the upstream version (which calls _load_notion_token()) with:

def _get_token() -> str:
    """Get the Notion token (set via --token-file CLI arg)."""
    if _notion_token is None:
        raise RuntimeError(
            "No Notion token. Pass --token-file <path> on the command line."
        )
    return _notion_token
