AI agents call role 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 queries role data within Access Groups without modifying, deleting, or executing any operations. It retrieves information about roles, making it a Read operation with low blast radius if misused, as it only exposes existing role data. Confidence is slightly reduced (0.85) due to incomplete description formatting, but the 'query' verb and parameter structure clearly indicate read-only intent.
From the tool's definition Tool name 'role' with description 'query role' indicates a read-only query operation for retrieving role information.

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