What github_list_repos does on Github
AI agents call github_list_repos to retrieve information from Github without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why github_list_repos is rated Low
The 'list' operation is a retrieval pattern that queries and returns data without creating, modifying, or deleting resources. Even though the description is empty, the tool name itself is sufficiently informative—'list' operations universally perform read-only queries. This carries low risk as it only exposes existing repository metadata.
From the tool's definition Tool name 'github_list_repos' indicates retrieval of repository information. No description provided, but the name pattern and sibling tools (github_clone_repo, github_archive_repo, etc.) confirm this is a read operation that queries GitHub repositories…
Attacks that exploit this kind of access
The rule that runs github_list_repos safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Github, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For github_list_repos, this is the rule to start with:
github_list_repos is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Github, apply this rule, and every github_list_repos call is checked against it from then on.

github_list_repos is a read tool on the Github MCP server. It is categorised as a Read tool in the Github MCP Server, which means it retrieves data without modifying state.
Register the Github MCP server in PolicyLayer and add a rule for github_list_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 Github. Nothing to install.
github_list_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 github_list_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 github_list_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.
github_list_repos is provided by the Github MCP server (dkeeno/github-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
