Claude Code plugin

The fastest path in Claude Code — installs the MCP server plus a retirement-planning skill that sequences the tools:

/plugin marketplace add cinderfi/cinderfi-mcp
/plugin install cinderfi@cinderfi

Then set your key so the server authenticates:

export CINDERFI_MCP_KEY=your_api_key   # from https://cinder.fi/mcp

Agents that support the auth.md protocol can also register for their own credential through a user-approved claim ceremony — no pasted key required.
