Return current GreyMatter API rate-limit usage (limit is 5000 points/hour per company account). Example variables: {}
AI agents call rate_limit to retrieve information from ReliaQuest GreyMatter MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and returns current rate-limit usage statistics. It has no side effects, does not modify any data, and cannot be misused to cause harm. It is a pure read/query operation with minimal blast radius.

Return current GreyMatter API rate-limit usage (limit is 5000 points/hour per company account). Example variables: {}. It is categorised as a Read tool in the ReliaQuest GreyMatter MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ReliaQuest GreyMatter MCP Server MCP server in PolicyLayer and add a rule for 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 ReliaQuest GreyMatter MCP Server. Nothing to install.
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 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 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.
rate_limit is provided by the ReliaQuest GreyMatter MCP Server MCP server (space-c0wboy/reliaquest-greymatter-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
