Get all topics for a specific date. Returns complete row from Matrix.
AI agents call get_matrix_row 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 retrieves data from a matrix/spreadsheet based on a date parameter and returns the results without side effects. It is a read operation with minimal blast radius—misuse would only expose data the agent can already access, not modify external systems or cause irreversible changes.
From the tool's definition Tool name 'get_matrix_row' and description 'Get all topics for a specific date. Returns complete row from Matrix' indicate data retrieval with no modification or deletion. The verb 'Get' and 'Returns' confirm query-only semantics.

Get all topics for a specific date. Returns complete row from Matrix. It is categorised as a Read tool in the Revenue Engine MCP MCP Server, which means it retrieves data without modifying state.
Register the Revenue Engine MCP server in PolicyLayer and add a rule for get_matrix_row: 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.
get_matrix_row 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 get_matrix_row 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 get_matrix_row. 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.
get_matrix_row 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.
