mcp-grafana-npx Write Risk 2/5

// WHEN AI AGENTS USE THIS TOOL

AI agents use update_annotation to create or modify resources in Mcp Grafana Npx. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON UPDATE_ANNOTATION

Without a policy, an AI agent could call update_annotation repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Grafana Npx.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the update_annotation tool do? +

Updates the provided properties of an annotation by ID. Only fields included in the request are modified; omitted fields are left unchanged.. It is categorised as a Write tool in the Mcp Grafana Npx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on update_annotation? +

Add a rule in your Intercept YAML policy under the tools section for update_annotation. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Grafana Npx MCP server.

What risk level is update_annotation? +

update_annotation is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit update_annotation? +

Yes. Add a rate_limit block to the update_annotation rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block update_annotation completely? +

Set action: deny in the Intercept policy for update_annotation. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides update_annotation? +

update_annotation is provided by the Mcp Grafana Npx MCP server (mcp-grafana-npx). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
