AI agents use create_case to create or update resources in ReliaQuest GreyMatter MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ReliaQuest GreyMatter MCP Server environment.
This tool creates and stores new case objects with state, type, and severity attributes. Creation of cases is a reversible write operation (cases can typically be deleted or modified later), not a read, destructive, financial, or executable operation. Severity is high because malicious case creation could flood the incident response system, obscure legitimate cases, or disrupt security operations workflows.
From the tool's definition Tool name 'create_case' and description explicitly states 'Create a case' — creates new case records in the GreyMatter platform. Requires state and type parameters that structure new persistent data.

Create a case. NOTE: state is effectively REQUIRED despite being schema-optional \u2014 omitting it makes the GreyMatter API return success=false with no error. Always pass state (e.g. NEW). type is required (GENERAL, DISCOVER_EXPOSURE, TEAMMATE); severity optional (INFORMATIONAL..CRITICAL). Variables: input. Example variables: {\. It is categorised as a Write tool in the ReliaQuest GreyMatter MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ReliaQuest GreyMatter MCP Server MCP server in PolicyLayer and add a rule for create_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.
create_case is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_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 create_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.
create_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.
