## MCP Proxy

The MCP Proxy is the primary configurable component. See the dedicated [MCP Proxy Configuration](/mcp-proxy/configuration/) page for:

- CLI flags (database paths, signing keys, DIDs)
- Policy rules (YAML format, actions, matching)
- Risk scoring and operation classification
- Approval workflows
- Data redaction and encryption at rest

## Taxonomy mappings

All SDKs and the MCP Proxy accept a taxonomy mappings file that maps tool names to action types:

```json
{
  "mappings": [
    { "tool_name": "read_file", "action_type": "filesystem.file.read" },
    { "tool_name": "write_file", "action_type": "filesystem.file.modify" },
    { "tool_name": "exec_command", "action_type": "system.command.execute" }
  ]
}
```

See the [Action Taxonomy](/specification/action-taxonomy/) specification for the full list of built-in action types.
