my-portfolio-mcp

A FastMCP server packaged so it installs into a Dataiku code env's site-packages, which is both readable by the impersonated run-as user and on PYTHONPATH.

Install into the Dataiku code env

1. Push this folder to a git repo your Dataiku instance can reach.

2. In Dataiku: Administration → Code envs → DJH_Local_MCP → Packages to install, add one line:

   git+https://YOUR-GIT-HOST/you/my-portfolio-mcp.git

   (Or build a wheel — python -m build — and reference that instead.)

3. Update / rebuild the code env.

Configure the Dataiku agent tool

• command: python

• args (two separate entries):

  • -m

  • mcpsrv.mcp_portfolio_server

That's it. Because the package is now in site-packages, -m resolves it and the file is readable — clearing both the ModuleNotFoundError and the Errno 13 permission error.

Local sanity check (optional)

pip install -e .
python -m mcpsrv.mcp_portfolio_server   # should start and wait on stdin; Ctrl-C to exit

Adding more tools

Add more @mcp.tool()-decorated functions in mcp_portfolio_server.py. Use absolute paths or package-relative imports inside them — the tool subprocess runs from a throwaway temp working directory, so bare relative paths will break.
