Search Matrix for keyword across topics and dates
AI agents call query_matrix to retrieve information from Revenue Engine MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search operation across a matrix (likely a data structure storing revenue/business information) using keywords and date filters. It is a read-only retrieval function with no capability to modify, delete, or execute external operations. The search/query nature and lack of any modification or execution semantics clearly place it in the Read category.

Register the Revenue Engine MCP server in PolicyLayer and add a rule for query_matrix: 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 Revenue Engine MCP. Nothing to install.
query_matrix 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 query_matrix 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 query_matrix. 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.
query_matrix is provided by the Revenue Engine MCP server (promptishoperations/mcpspec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
