Grafana MCP server (Loki tools)

Grafana Loki does not itself ship an MCP server. The Loki query surface reaches MCP clients through the Grafana Labs MCP servers, which expose Loki as a datasource: the open-source grafana/mcp-grafana server (local stdio / SSE / streamable-http) and the fully hosted Grafana Cloud MCP server at https://mcp.grafana.com/mcp (OAuth 2.1, streamable HTTP only). Both are first-party Grafana Labs software; the Loki tool family below is registered by tools/loki.go in grafana/mcp-grafana.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
