Read Matrix entries for a date range. Returns all entries for specified topics and dates.
AI agents call read_matrix_snapshot 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 queries and retrieves historical data from a matrix/spreadsheet without creating, modifying, or deleting any entries. It is a pure read operation with no side effects. The low severity reflects minimal blast radius—misuse would only expose data already accessible to the AI agent, not cause irreversible harm or financial impact.
From the tool's definition Tool name 'read_matrix_snapshot' and description 'Read Matrix entries for a date range. Returns all entries for specified topics and dates.' explicitly indicates a retrieval operation with no modification or deletion of data.

Register the Revenue Engine MCP server in PolicyLayer and add a rule for read_matrix_snapshot: 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.
read_matrix_snapshot 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 read_matrix_snapshot 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 read_matrix_snapshot. 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.
read_matrix_snapshot 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.
