AI agents call discover_tasks 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 is a task discovery/enumeration tool that queries existing tasks without modifying, deleting, or executing any operations. It retrieves information from the ReliaQuest GreyMatter platform, fitting the Read category. The low severity reflects minimal blast radius—unauthorized task discovery is an informational risk rather than operational damage.
From the tool's definition Tool name 'discover_tasks' with 'query discoverTasks' indicates a GraphQL query operation. The variables (after, filter, first, order) are typical pagination and filtering parameters for data retrieval with no mutation operations.

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 discover_tasks: 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.
discover_tasks 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 discover_tasks 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 discover_tasks. 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.
discover_tasks 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.
