50 tools. 9 can modify or destroy data without limits.
9 write tools that can modify data. Rate limits recommended.
Last updated:
Write operations (add_activity_to_incident, alerting_manage_routing, alerting_manage_rules) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Intercept sits between your agent and Mcp Grafana Npx. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @mcp-grafana-npx add_activity_to_incident:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
find_error_pattern_logs:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Mcp Grafana Npx server has 9 write tools including add_activity_to_incident, alerting_manage_routing, alerting_manage_rules. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
50 tools across 2 categories: Read, Write. 41 are read-only. 9 can modify, create, or delete data.
One line change. Instead of running the Mcp Grafana Npx server directly, prefix it with Intercept: intercept -c mcp-grafana-npx.yaml -- npx -y @mcp-grafana-npx. Download a pre-built policy from policylayer.com/policies/mcp-grafana-npx and adjust the limits to match your use case.
Set budgets, approvals, and hard limits across MCP servers.
