Skills Are Powerful, But Useless Without the Right Tools

Tool management for agents gets messy fast: dozens of tools per server, skills copied between projects, and CLI commands that each need wiring up. CAPA handles all of it from one file.

Quick Installation

curl -LsSf https://capa.infragate.ai/install.sh | sh
powershell -ExecutionPolicy ByPass -c "irm https://capa.infragate.ai/install.ps1 | iex"

One Server, Only the Tools You Need

MCP servers often bundle dozens of tools, but you only need a few. CAPA creates one server that exposes only the tools your skills actually use.

Reusable Skills

Stop duplicating skills across projects. Reference them from GitHub, GitLab, or local repos in your capabilities file.

Any MCP, Instantly a CLI

CAPA turns every configured MCP tool into a command you can run on the fly. Call any server with capa sh <server> <tool>, without writing wrappers or glue code.

Tools Load On Demand

Agents start with a minimal tool set and pull in the rest by name when a task needs them. Profiles switch automatically based on what you're working on.

Self-Improving Agents

The capabilities file lives in your project, so the agent can edit it to add new skills as it works.

Security

Block dangerous phrases and sanitize skill content before installation. Configure allowed character sets and blocked phrase lists.
