List repositories a team can access, with the team's permission on each.
AI agents call list_team_repos to retrieve information from Ghe Mcp Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about repository access for a team without modifying any data or triggering side effects. It is a straightforward query operation that lists existing resources and their associated permissions. The low severity reflects the read-only nature and limited blast radius if misused by an AI agent—it would only expose information about team access permissions, not enable unauthorized actions.
From the tool's definition Tool name 'list_team_repos' and description 'List repositories a team can access' indicate a retrieval operation. The server description states 'read-only safety by default.' No creation, modification, deletion, or execution of code/commands is described.
Attacks that exploit this kind of access
List repositories a team can access, with the team's permission on each. It is categorised as a Read tool in the Ghe Mcp Gateway MCP Server, which means it retrieves data without modifying state.
Register the Ghe Mcp Gateway MCP server in PolicyLayer and add a rule for list_team_repos: 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 Ghe Mcp Gateway. Nothing to install.
list_team_repos 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_team_repos 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_team_repos. 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_team_repos is provided by the Ghe Mcp Gateway MCP server (mholzinger/ghe-mcp-gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
