# FilingCabinet > MCP-native secrets, API-token, and Terraform/OpenTofu state vault. A > human manages credentials through a web UI; an authenticated agent > manages the same data through MCP. Nothing is ever hard-deleted — > every write is a new version, and any version can be rolled back to. ## Docs - [MCP integration guide](http://filing-cabinet-file-cabinet.someones.computer/docs/mcp): what this tool surface does and how to connect. - [Machine-readable manifest](http://filing-cabinet-file-cabinet.someones.computer/.well-known/mcp.json): MCP endpoint, docs, and connect URLs as JSON. - [Connect an agent](http://filing-cabinet-file-cabinet.someones.computer/connect): sign in and mint a scoped API token (requires a human to log in first).
