AI agents call teammate_discover_teams 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 performs a read-only discovery operation on the local filesystem to enumerate teams. There are no side effects, no data modification, no code execution, and no destructive operations. The blast radius of misuse is minimal—an AI agent could at worst learn about existing teams, which poses no security risk beyond potential information disclosure of team names/metadata.
From the tool's definition Tool name 'discover_teams' and description 'Discover existing teams in ~/.claude/teams/' indicate a query/list operation that retrieves information about existing teams from the filesystem without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
Discover existing teams in ~/.claude/teams/. 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 teammate_discover_teams: 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.
teammate_discover_teams 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 teammate_discover_teams 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 teammate_discover_teams. 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.
teammate_discover_teams 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.
teammate_discover_teams 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.
