Pull Request Overview
This PR adds comprehensive integration tests to verify that the mcp inspect command correctly validates GitHub MCP server configuration across all three agentic engines (copilot, claude, and codex). The tests follow the existing integration test pattern using the shared setupIntegrationTest() helper and verify frontmatter validation, MCP configuration validation, and GitHub server/tool detection.
Key Changes:
- New integration test file with three test functions covering different scenarios
- Tests validate GitHub tool configuration for all three engines
- Verification of toolsets configuration (repos, issues, pull_requests, actions)

The error handling logic in this test is inconsistent with the pattern used in mcp_inspect_playwright_integration_test.go.
In the Playwright test (lines 87-97), the error check happens first before doing other validations. This prevents false positives when the command fails for unexpected reasons.
Current GitHub test pattern:
- Check output contents (lines 83-123)
- Check error at the end (lines 125-137)
Recommended Playwright test pattern:
- Check error first (with acceptable conditions)
- Then check output contents
This ensures that if there's an unexpected error, it's caught immediately before spending time checking output that may be incomplete or misleading.

Refactored all three test functions to check errors first before validating output, matching the Playwright test pattern. This change was applied to:
- TestMCPInspectGitHubIntegration
- TestMCPInspectGitHubToolsListing
- TestMCPInspectGitHubWithSpecificToolsets
All tests still pass with the updated error handling logic. Commit: a2ee647
Following the Playwright test pattern, moved error checking to happen before output validation in all three test functions. This prevents false positives when the command fails for unexpected reasons. Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>
