# contract-testing_matrix Retrieve the comprehensive contract verification matrix that shows the relationship between consumer and provider versions, their associated pact files, and verification results stored in the Pact Broker or Pactflow. The matrix provides detailed visibility into which consumer and provider versions have been successfully verified against each other, and highlights failures with detailed information about the cause. Parameters: - latestby (string): This property removes the rows for the overridden pacts/verifications from the results. The options are cvp (show only the latest row for each consumer version and provider) and cvpv (show only the latest row each consumer version and provider version). For a can-i-deploy query with one selector, it should be set to cvp. For a can-i-deploy query with two selectors, it should be set to cvpv. - limit (number): The limit on the number of results to return (1-1000, default: 100) (default: 100) - q (array) *required* Use Cases: 1. Quickly identify which consumer and provider version combinations have passed or failed verification. 2. Diagnose and investigate why a particular consumer-provider verification failed. 3. Visualize the overall contract compatibility across two pacticipants / services. 4. Perform advanced queries using selectors to understand compatibility within specific branches, environments, or version ranges. 5. Support informed deployment decisions by answering 'can I deploy version X of this service to production?' 6. Expose contract verification details to non-frequent API users in a more accessible format. Agent View of the PolicyLayer registry record for `contract-testing_matrix`.

It has no side effects—it only reads existing verification data and relationship matrices. The parameter 'latestby' filters results but does not modify underlying data. This is a pure Read operation: no data is created, modified, deleted, or financial operations are performed. From the tool's own definition: "Tool name contains 'matrix' and description states 'Retrieve the comprehensive contract verification matrix' and 'provides detailed visibility into which consumer and provider versions have been successfully verified.' The action is retrieval of verification…" Risk signals: High parameter count (10 properties) ## Use case AI agents call contract-testing_matrix to retrieve information from SmartBear MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
