Question 640
At the Pinecrest housing nonprofit after a wider deployment, a custom Foundry agent can access a Power Platform MCP server with a broad service credential rather than delegated permissions. The operations team needs a supportable remediation with evidence for the handover. Which ongoing engineering control would most directly reduce recurrence?
Explanation
Correct Answer
The most relevant long-term safeguard is to reassess MCP permissions and tool schemas when adding operations. It preserves the remediation to configure least-privilege MCP tool access and validate identity and authorization at the server as operating conditions change. In the Pinecrest housing nonprofit, assess this against the documented mcp server trust boundary scenario.
Incorrect Answers
“Review identity assignments and least-privilege permissions during rollout” checks a different ongoing risk rather than the reported failure: at the Pinecrest housing nonprofit after a wider deployment, a custom Foundry agent can access a Power Platform MCP server with a broad service credential rather than delegated permissions. The operations team needs a supportable remediation with evidence for the handover. The relevant mechanism is tool connectivity does not bypass permissions or justify unrestricted service identity. The directly matched preventive control is “Reassess MCP permissions and tool schemas when adding operations”.
That safeguard is appropriate for maintaining work iq user context. It would not primarily prevent the reported failure, for which the relevant control is to reassess MCP permissions and tool schemas when adding operations. For case R082-PL400-CASE-0160, the decisive context is the 2 deployment setting at the Pinecrest housing nonprofit.
“Test cross-agent identity boundaries and failures after updates” checks a different ongoing risk rather than the reported failure: at the Pinecrest housing nonprofit after a wider deployment, a custom Foundry agent can access a Power Platform MCP server with a broad service credential rather than delegated permissions. The operations team needs a supportable remediation with evidence for the handover. The relevant mechanism is tool connectivity does not bypass permissions or justify unrestricted service identity. The directly matched preventive control is “Reassess MCP permissions and tool schemas when adding operations”.
