info · Rr MCP: Risk & Policy

WHAT IT DOES

What info does on Rr

AI agents invoke info to trigger actions in Rr. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why info needs a policy

GDB execution allows arbitrary debugging commands that can inspect memory, modify program state, and trigger execution paths. While not directly destructive without explicit delete commands, this is an Execute-category tool because it runs external operations (GDB commands) whose effects depend on what arguments are passed.

From the tool's definition Tool description states 'Run a GDB' - GDB is a debugger that executes commands to inspect and control program execution.

Verdict

info Rate-limited

info stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Rr, so you can run agents against it safely.

FAQ

Questions about info

What does the info tool do? +

Run a GDB. It is categorised as a Execute tool in the Rr MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on info? +

Register the Rr MCP server in PolicyLayer and add a rule for info: 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 Rr. Nothing to install.

What risk level is info? +

info is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit info? +

Yes. Add a rate_limit block to the info 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.

How do I block info completely? +

Set action: deny in the PolicyLayer policy for info. 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 info? +

info is provided by the Rr MCP server (jnjaeschke/rr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
