Detects unauthenticated attempts to invoke Grafana API tools via the Model Context Protocol (MCP) by utilizing spoofed Mcp-Session-Id headers while bypassing bearer token authentication requirements. This primarily targets unauthorized access to API functionality on Grafana instances configured with bearer-token authentication (v1.1.0+).

Detects potential Server-Side Request Forgery (SSRF) attacks targeting Grafana instances. The rule identifies suspicious 'grafana_api_request' calls that occur shortly after an unauthenticated discovery call ('tools/call') within the same session, where the target URL in the request header is not included in a defined allowlist of known internal Grafana hosts.

Detects instances where unauthenticated users or sessions execute privileged 'tools/call' operations within the Grafana MCP dispatcher. This behavior is indicative of potential session spoofing attacks, specifically targeting vulnerabilities similar to CVE-2026-19516, where lack of an Authorization header allows unauthorized access to privileged tool functions.

Detects instances of an mcp-grafana server responding with an HTTP 200 status code to a 'tools/call' request without an Authorization header, indicating potential unauthenticated remote tool execution on a vulnerable or misconfigured server.

Detects anomalous outbound network connections from the Grafana MCP (Model Context Protocol) server process to internal private IP address ranges. The rule compares current network activity against a 14-day baseline to filter out known data sources, identifying potentially unauthorized lateral movement or internal network probing via server-side request forgery (SSRF) vulnerabilities.

Detects invocations of the 'grafana_api_request' tool that lack a preceding valid bearer-token authentication event for the same session. This indicates a potential scenario where a server or service account token is being used on behalf of an unauthenticated caller, bypassing normal authentication requirements for the Grafana API.
