AI agents call list_pyroscope_profile_types to retrieve information from Mcp Grafana Npx without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though list_pyroscope_profile_types only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access list_pyroscope_profile_types gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Lists all available profile types available in a specified Pyroscope datasource and time range. Returns a list of all available profile types (example profile type: "process_cpu:cpu:nanoseconds:cpu:nanoseconds"). A profile type has the following structure: <name>:<sample type>:<sample unit>:<period type>:<period unit>. Not all profile types are available for every service. If the time range is not provided, it defaults to the last hour.. It is categorised as a Read tool in the Mcp Grafana Npx MCP Server, which means it retrieves data without modifying state.
Register the Mcp Grafana Npx MCP server in PolicyLayer and add a rule for list_pyroscope_profile_types: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Grafana Npx. Nothing to install.
list_pyroscope_profile_types is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_pyroscope_profile_types rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for list_pyroscope_profile_types. 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.
list_pyroscope_profile_types is provided by the Mcp Grafana Npx MCP server (mcp-grafana-npx). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
