Get statuses for a commit
AI agents call get_commit_statuses to retrieve information from Mcp Github without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries commit status data from GitHub with no side effects. It performs a GET-like operation that does not create, modify, delete, or execute any code. The blast radius of misuse is minimal—an attacker could only access commit status information that would likely already be visible through normal repository access.
From the tool's definition Tool name 'get_commit_statuses' and description 'Get statuses for a commit' indicate a read-only query operation that retrieves status information without modifying any data.
Attacks that exploit this kind of access
Get statuses for a commit. It is categorised as a Read tool in the Mcp Github MCP Server, which means it retrieves data without modifying state.
Register the Mcp Github MCP server in PolicyLayer and add a rule for get_commit_statuses: 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 Mcp Github. Nothing to install.
get_commit_statuses 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 get_commit_statuses 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 get_commit_statuses. 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.
get_commit_statuses is provided by the Mcp Github MCP server (@missionsquad/mcp-github). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
