Manage meters with Mediation MCP

Use this reference to discover, validate, create, update, import, export, and duplicate Mediation meters.

The manage_meters tool manages meter definitions and configuration. It provides 19 operations for event schemas, event stores, connections, task graphs, validation, and meter lifecycle actions.

Start with meter_guidance to retrieve workflows and tips. Do not invent operation parameters. Use the guidance operation or the tool schema to determine the supported parameters.
