FAQ from Mcpn

What dependencies does Mcpn require?

Mcpn is an npm package run via npx, so Node.js must be installed on your system.

How can I share workflows with my team?

Store your YAML files in a .workflows or .mcp-workflows directory and commit them to a git repository. Team members then point to the same config folder using --config.

Which presets are included out of the box?

Three presets are available: thinking (reasoning modes), coding (debugging, architecture, planning, PRD), and github (PR review, PR creation, branch creation, save changes).

How do I define custom workflows with parameters?

Create a YAML file with a workflow name, description, prompt containing {{ parameter_name }}, and a parameters block specifying each parameter’s type, description, and required flag.

Can I control the order tools are used in a workflow?

Yes. Set toolMode: sequential to execute tools in the exact order listed; omit it (or set situational) to let the AI decide which tools to use as needed.
