List recent commits in a GitHub repository
AI agents call list_repo_commits to retrieve information from GitHub MCP TypeScript SDK 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 retrieves commit history from a repository, which is a read-only data access operation. Listing commits does not create, modify, delete, or execute any actions—it only fetches historical information that is already public or accessible to the authenticated user. The low severity reflects minimal blast radius; misuse would only expose existing commit metadata.
From the tool's definition Tool name 'list_repo_commits' and description 'List recent commits in a GitHub repository' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List recent commits in a GitHub repository. It is categorised as a Read tool in the GitHub MCP TypeScript SDK Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub MCP TypeScript SDK Server MCP server in PolicyLayer and add a rule for list_repo_commits: 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 MCP TypeScript SDK Server. Nothing to install.
list_repo_commits 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_repo_commits 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_repo_commits. 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_repo_commits is provided by the GitHub MCP TypeScript SDK Server MCP server (om-shree-0709/github-mcp-ts-sdk). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
