UK Parliament NOW Annunciator MCP Server

Summary

This MCP server provides structured access to UK Parliament NOW Annunciator data using the Model Context Protocol. It enables AI agents to retrieve current and historical annunciator messages through API-backed tools and data access. Developers can integrate the MCP server via stdio transport to query message feeds for Commons and Lords. The server exposes tools that map directly to the NOW Annunciator API for automation and AI agents workflows.

Features

• Retrieve the current annunciator message for Commons or Lords.
• Fetch the latest message after a specific date and time.
• Enforce annunciator enum constraints for reliable queries.
• Preserve upstream payloads in a standardized envelope for downstream tools.
