## Connect

- MCP: `claude mcp add --transport http thirdfy https://mcp.thirdfy.com/mcp` (docs: https://docs.thirdfy.com/documentation/mcp)
- CLI: `npx @thirdfy/agent-cli@latest login` (add `--trade` to allow writes), then `npx @thirdfy/agent-cli@latest whoami`
- The owner allows Vaults.fyi for the agent: https://v2.thirdfy.com/integrations/vaults-fyi

## Actions

- `get-vaults-fyi-vaults` (read): Discover Vaults.fyi vault opportunities through the shared Earn registry and secret-backed Vaults.fyi adapter.

## Rules

- Call these actions through Thirdfy, not with your own keys: Thirdfy builds each transaction and the owner's policy checks it before it signs.
- A write that the owner has not allowed, or that breaks a limit, is refused before signing and costs nothing.
