AI agents call guidance_discover to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists available agents and skills from a directory structure—a data discovery/introspection operation. It queries the filesystem state without creating, modifying, deleting, or executing arbitrary code. The verb 'discover' and 'returns live filesystem data' confirm it is a read operation. No reversible writes, destructive actions, code execution, or financial implications are present.
From the tool's definition Tool name 'guidance_discover' and description 'Discover all available agents and skills from the .claude/ directory. Returns live filesystem data.' indicate read-only filesystem querying with no side effects.
Attacks that exploit this kind of access
Discover all available agents and skills from the .claude/ directory. Returns live filesystem data. Use when generic. It is categorised as a Read tool in the Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo MCP server in PolicyLayer and add a rule for guidance_discover: 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 Ruflo. Nothing to install.
guidance_discover 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 guidance_discover 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 guidance_discover. 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.
guidance_discover is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
guidance_discover is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
