README
pixi-task
A secure MCP server providing controlled access to pixi tasks and commands, eliminating agent bash circumvention.
Overview
Exposes 11 pixi tools through 4 lean meta-tools (discover_tools, get_tool_spec, execute_tool, server_info) for ~95% context savings compared to a traditional MCP server that advertises every tool individually.
Two transports are supported:
- stdio — exposes the full registry (11 tools).
- HTTP — gates the surface to
core+extendedcomplexity (7 tools); use this for daemonised deployments. Default port:4101.
Both transports surface a server_info meta-tool for self-identification (name, version, transport label, live tool counts, source URLs).
Development
pixi install -e quality
pixi run test
pixi run lint
pixi run format
pixi run typecheck
The HTTP server can be run directly:
pixi run http-server --port 4101
For background operation, the repo ships a systemd user unit at ~/.config/systemd/user/pixi-task.service.
Available Tasks
The canonical task list lives in [tool.pixi.tasks] in pyproject.toml. Key tasks:
| Task | Purpose |
