## Use cases
Ravn is 25 contact and company data tools behind one key. You can reach them from Claude through the [MCP server](https://askravn.com/mcp-server), from a terminal with the CLI, or from your own code over REST. Every route returns the same answer shape, so a playbook written for one works in the others.These playbooks are written so a person can follow them, or hand them to an agent and let it run. Each one says which tools it uses, in what order, what to do with each answer and what it will cost on each [plan](https://askravn.com/pricing). A miss is always free.
