'openaccountants-mcp' command not found after pip install
The pip install may have put the script in a directory not on your PATH. Run 'pip show openaccountants-mcp' to find the installation location, then add the Scripts (Windows) or bin (macOS/Linux) folder to your PATH, or use the full absolute path in the MCP config 'command' field.
MCP client shows the server as disconnected
Run 'openaccountants-mcp' directly in a terminal to check for error output. Python version mismatches (the package requires Python 3.10+) are a common cause. Verify with 'python3 --version'.
get_skill returns 'skill not found' for a specific jurisdiction
First call 'list_jurisdictions' to see the exact jurisdiction identifiers available. Skill names follow a 'jurisdiction-skill-name' pattern (e.g., 'germany-payroll'). Use the exact identifiers returned by list_jurisdictions.
