Getting Started

Install or upgrade

uv tool install -U fast-agent-mcp

If you have multiple Python versions installed, pin the one required by fast-agent:

uv tool install -U fast-agent-mcp --python 3.13.5

Run

fast-agent go

Run a card pack

fast-agent go --pack analyst --model haiku
fast-agent go --pack analyst --pack-registry ./marketplace.json --agent planner --model haiku

--pack installs the pack into the selected fast-agent environment if needed, then launches go normally. --model is a fallback for cards without an explicit model setting.

fast-agent go -i prompt.md
fast-agent go -i https://gist.github.com/....

Model override

fast-agent go --model sonnet
