AI agents call me 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 retrieves information about the current user without modifying, executing, or destroying data. It is a simple read operation typical of identity/profile queries. The low severity reflects minimal blast radius—an agent querying user information poses minimal risk.
From the tool's definition Tool name 'me' with description 'User · query me' indicates a user profile/identity query operation. The variables (after, filter, first, order) are pagination and filtering parameters consistent with a read-only GraphQL query pattern.

Register the ReliaQuest GreyMatter MCP Server MCP server in PolicyLayer and add a rule for me: 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.
me 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 me 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 me. 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.
me 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.
