Perplexity

Search and identify issuers instantly

You use `search_entities` to find specific organizations and map them to their official Moody's identifiers. Your agent runs this search directly inside Claude Desktop, pulling up-to-date entity matching without forcing you to open a browser tab or run manual script queries. Once your agent locates the correct organization, it extracts the exact entity ID you need for deeper risk analysis. You get clean, structured results returned directly to your chat window, making it easy to pivot immediately to rating lookups.

Audit debt credit ratings in Claude Desktop

You call `list_issue_ratings` and `get_issue_details` to pull current credit ratings and structures for specific debt instruments directly inside Claude Desktop. This lets your agent inspect individual bond issuances and compare their risk profiles against your internal compliance thresholds. The tool feeds raw rating data straight to your desktop chat, allowing you to quickly spot downgrades or credit shifts. Your agent can then cross-reference these ratings against the scale definitions using `get_rating_reference` to translate complex codes into clear risk tiers.

Track rating actions inside this MCP Server

You track credit events using `list_rating_actions` to watch for recent upgrades, downgrades, or outlook changes across your coverage list. Running this MCP Server through Claude Desktop gives your agent a direct feed to monitor market movements and flag sudden credit shifts. Your agent processes these real-time rating updates and maps them directly to specific business sectors using `get_market_segments`. This setup means you notice credit deterioration before it impacts your portfolio balance.
