Enumerate every cross-repo group defined under ~/.codehub/groups. Groups bundle already-indexed repos so an agent can run one query across a whole stack (web-client + api-server + shared libs). Returns each group
AI agents call group_list to retrieve information from OpenCodeHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and lists pre-defined group configurations from the user's local filesystem (~/.codehub/groups). It has no side effects, does not execute code or commands, does not modify data, and does not commit any operations. It is a straightforward inventory/discovery operation with minimal blast radius if misused by an agent.
From the tool's definition Tool description states it 'Enumerate[s] every cross-repo group' and 'Returns each group' — pure enumeration/retrieval with no modification, deletion, or execution. The verb 'Enumerate' and 'Returns' indicate read-only query semantics.

Attacks that exploit this kind of access
Enumerate every cross-repo group defined under ~/.codehub/groups. Groups bundle already-indexed repos so an agent can run one query across a whole stack (web-client + api-server + shared libs). Returns each group. It is categorised as a Read tool in the OpenCodeHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenCodeHub MCP Server MCP server in PolicyLayer and add a rule for group_list: 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 OpenCodeHub MCP Server. Nothing to install.
group_list 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 group_list 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 group_list. 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.
group_list is provided by the OpenCodeHub MCP Server MCP server (theagenticguy/opencodehub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
