SigNoz MCP server: access metrics, traces, logs, alerts, and dashboards via AI assistants
A Model Context Protocol (MCP) server that provides seamless access to SigNoz observability data through AI assistants and LLMs. Query metrics, traces, logs, alerts, dashboards, and services using natural language.
signoz_check_metric_usage (it reads v2/Perses dashboards for dashboard usage; on older versions the dashboard half is silently empty, though alert usage alone works from v0.131.0) -Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
