ijuka-mcp (Python shim for uvx)

This is a tiny Python wrapper that makes the Ijuka MCP server runnable via uvx — the pattern many MCP clients expect:

Command: uvx
Parameters: ijuka-mcp

The Swift helper is still the real server; this package just finds the bundled binary at /Applications/<app>.app/Contents/Helpers/ijuka-mcp (or the dev helpers in ~/bin, /usr/local/bin, DerivedData) and execs it, forwarding stdio.

uvx (uv tool run) holds the uv cache lock for the lifetime of the server (astral-sh/uv#15990). With several clients all using uvx the spawns serialize and can hit the 10 s handshake timeout. For multi-client / daily use install once persistently.

Install / run

# One-off / trial — no install, uses cached env after first run:
uvx ijuka-mcp --help
# Pin for reproducibility:
uvx ijuka-mcp==1.2.0 --help

# Daily / multi-client — persistent, fastest, no cache-lock contention:
uv tool install ijuka-mcp
ijuka-mcp --help

# Update the persistent install:
uv tool upgrade ijuka-mcp

Local development (no PyPI):

uvx --from ./python ijuka-mcp --help
uv tool install --from ./python ijuka-mcp

All arguments are passed through, so tier/profile flags still work:

ijuka-mcp --help
ijuka-mcp --profile work

Troubleshooting: uvx timeout or Waiting to acquire lock

If several AI clients launch uvx ijuka-mcp at once and one times out, either switch that client to the persistent ijuka-mcp command or re-run the failing uvx once - uv cache is shared and uvx retains a shared lock for the server lifetime. uv tool install avoids the lock entirely.
