Claude Desktop MCP Server for LLM Observability

You can pull exact conversational node topologies directly into your chat interface using `get_thread`. Claude reads the raw programmatic interaction steps defining prompts and generations inside a single thread via `list_steps`. PMs and developers skip jumping between dashboards. Your agent grabs the exact payload for a specific thread, letting you inspect exactly what the model generated.

Track Project Usage and Metrics

Calling `list_projects` returns your globally configured Chainlit Cloud projects and their independent tracking spaces. Once connected, your MCP agent uses `get_stats` to pull traffic boundaries and resource consumption. Analyzing application usage happens right inside the chat window. You just ask for the numbers, and it fetches explicit analytics statistics without requiring you to open a separate browser tab.

Review User Feedback and Ratings

Fetching absolute user review ratings across deployments takes one command with `list_feedbacks`. The agent reads conversational accuracy and value scores assigned by actual users. Product teams need to know how users react to model outputs. Running `list_threads` identifies user interaction boundaries inside a specific deployed project, giving you the full context behind every positive or negative rating.
