AI agents call case 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 case information from the GreyMatter platform through parameterized queries. It accepts filtering, ordering, and pagination arguments but performs no write, delete, or execution operations. The 'query' keyword and parameter structure (filter, order, after) are characteristic of read-only data retrieval operations. No side effects or data modifications are indicated.
From the tool's definition Tool name and description indicate 'query case' operation with filtering and ordering parameters (after, filter, first, order, etc.).

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