Check the current rate limit status
AI agents call get_rate_limit 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 only queries the GitHub API's rate limit status, returning informational data about request quotas. It has no side effects, cannot modify or delete data, and poses minimal security risk even if misused by an AI agent.
From the tool's definition Tool name is 'get_rate_limit' and description states it 'Check the current rate limit status' — a read-only operation that retrieves information without modifying any data.
Attacks that exploit this kind of access
Check the current rate limit status. 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_rate_limit: 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_rate_limit 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_rate_limit 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_rate_limit. 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_rate_limit 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.
