Appendix: Testing MCP Integrations
MCP turns tools, files, and services into model-accessible capabilities. That makes it a quality and security boundary.

What to do
- Start with contract testing.
- Test permission boundaries.
- Test prompt injection through resources.
- Treat MCP definitions as versioned release artifacts.
Evidence to preserve
- Preserve the inputs, versions, configurations, raw outcomes, and results for integration, MCP integration, mcp integrations needed to reproduce work on Appendix: Testing MCP Integrations.
- Report results for integration, MCP integration, mcp integrations by relevant slice, separate blocker failures from averages, state uncertainty and blind spots, and connect the result to a release decision.
Expert note
MCP testing combines API contract tests, authorization tests, prompt-injection tests, trace validation, schema fuzzing, tool-selection evals, and production monitoring. The MCP layer should be boring, observable, and constrained.
