description	Manages and retrieves Sovereign system configuration parameters and operational constants.

Config Registry MCP

The Config Registry is a specialized Sovereign system service responsible for the centralized management and retrieval of configuration parameters. It ensures that all other MCP services have a single source of truth for thresholds, modes, and constants.

Identity

The Config Registry acts as the Sovereign Epistemic Anchor for system settings. It provides a read-only (primarily) interface to the core configuration file, ensuring that operational parameters are consistent across the distributed architecture.

Commands

/config_get

• Behavior: Retrieves a specific configuration value using dot-notation (e.g., Soter.RiskThreshold).
• Input: path (string)
• Output: JSON object containing the value and path.

/config_get_all

• Behavior: Returns the entire system configuration.
• Security: Automatically masks secrets (passwords, keys) using the SecretMasker logic.
• Output: Masked configuration JSON including version and last load timestamp.

/config_get_section

• Behavior: Retrieves a specific top-level configuration block (e.g., "Soter", "Ethos").
• Input: section (string)
• Output: Masked JSON object for the requested section.

/config_reload

• Behavior: Forces the service to re-read the SOVEREIGN_CONFIG.yaml from the workspace.
• Input: None
• Output: Success/Failure status and new configuration version.

Operational Constraints

• Read-Only by Default: The registry primarily serves as a provider. Configuration changes are typically made to the file on disk by an authorized agent and then reloaded.
• Secret Masking: No raw secrets are ever emitted via MCP tools.
• Path Validation: Invalid dot-notation paths result in a specific error message rather than a system crash.

Implementation Details

• Storage: Backed by SOVEREIGN_CONFIG.yaml.
• Architecture: Implemented as a Python FastMCP server with a decoupled logic layer for configuration loading and secret masking.
