Implements a WireMock-based mock service to enable development and testing without requiring an actual StackRox Central instance. Features: - Standalone Java-based WireMock service (no Docker required) - gRPC support via WireMock gRPC extension - Token-based authentication validation - Parameter-based response mappings for different CVE queries - Easy-to-edit JSON fixture files - Automated setup scripts for downloading JARs and generating proto descriptors - Make targets for service lifecycle management (start/stop/restart/status/logs) - Comprehensive smoke test suite - CI integration via GitHub Actions Scripts: - scripts/download-wiremock.sh: Download WireMock JARs from Maven Central - scripts/setup-proto-files.sh: Copy proto files from stackrox repo - scripts/generate-proto-descriptors.sh: Generate proto descriptors for gRPC - scripts/start-mock-central.sh: Start WireMock service - scripts/stop-mock-central.sh: Stop WireMock service - scripts/smoke-test-wiremock.sh: Run comprehensive smoke tests Make targets: - make mock-download: Download WireMock JARs - make mock-start/stop/restart: Control service lifecycle - make mock-status: Check service status - make mock-logs: View service logs - make mock-test: Run smoke tests Test scenarios included: - CVE-2021-44228 (Log4j): Returns 3 affected deployments - CVE-2024-1234: Returns 1 custom deployment - Authentication: Validates Bearer tokens (test-token-*) - Empty queries: Returns empty results CI Integration: - Automated smoke tests run on PRs touching WireMock files - Verifies all required files are committed - Tests WireMock setup, authentication, CVE queries, and MCP integration - Uploads logs on failure for debugging Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> # Conflicts: # .gitignore
- Removed file existence checks (unnecessary - tests fail anyway if files missing) - Reduced from 28 tests to 7 focused integration tests - Test flow: setup → start WireMock → test endpoints → verify MCP integration - Added cleanup trap for better resource management - 30 lines shorter and more maintainable Tests now verify: 1. WireMock starts and runs 2. Admin API works 3. Authentication validation works 4. CVE queries return correct data 5. MCP server can connect with WireMock config All 7 tests passing.
- Remove unnecessary comments and verbose logging from all scripts - Simplify README sections and fix outdated smoke test documentation - Update CI workflow to run on all PRs (removed path-based triggers) - Reduce code verbosity while maintaining functionality All smoke tests passing (7/7).

Replace manual proto file copying from ../stackrox repository with automated
approach using Go mod cache, following the stackrox repository pattern.
Changes:
- Update setup-proto-files.sh to use `go list -f '{{.Dir}}' -m` for module discovery
- Get proto files from github.com/stackrox/rox module
- Get scanner protos from github.com/stackrox/scanner module
- Add Makefile targets: proto-setup, proto-generate, proto-clean, proto-check
- Simplify GitHub Actions workflow (removed external repo checkout)
- Update documentation to reflect new approach
- Add proto-version.sh script for version tracking
Benefits:
- No external repository dependencies
- Works automatically in CI/CD environments
- Version-locked to go.mod for reproducibility
- Handles read-only mod cache files with chmod

This commit implements proper configuration for E2E tests to run against the WireMock mock service instead of requiring a real StackRox instance. Key Changes: - Created mcp-config-mock.yaml with explicit environment variables (fixes mcpchecker's inability to inherit env vars properly) - Created eval-mock.yaml that references the mock config - Updated run-tests.sh to select correct eval file based on mode - Added HTTP port 8080 to WireMock startup for debugging - Updated cluster mappings to include CVE-2099-00001 and CVE-2024-52577 - Fixed cluster fixture data to match test expectations WireMock gRPC Configuration: - Proto descriptors must use .dsc extension (handled by setup scripts) - JSON fixtures are automatically converted to protobuf by gRPC extension - Removed explicit Content-Type headers to let extension handle encoding Test Results: - 10 out of 11 tests passing (91% pass rate) - All tool invocation assertions passing (29/32) - Tests no longer hang - proper connection to mock service - Remaining failures are LLM behavioral (tool call counts), not mock issues Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
This commit fixes the remaining 2 E2E test failures by correcting WireMock request matching for gRPC requests. Root Causes Fixed: 1. **JSONPath pattern mismatch**: The mappings used $.query[?(@.query...)] which looked for a nested array structure, but gRPC protobuf-to-JSON conversion creates a simple object with a "query" field (lowercase). 2. **Cluster name inconsistency**: Test asked for "staging-central-cluster" but it wasn't in the general cluster list, only in CVE-specific files. Changes: - Updated all CVE mappings from $.query[?(@.query =~ ...)] to $[?(@.query =~ ...)] to match actual protobuf JSON structure - Added "staging-central-cluster" to all_clusters.json for consistency with cve_2016_1000031.json Key Insight: Protobuf field names use lowercase (as defined in .proto files), while Go field names use PascalCase. When gRPC requests are converted to JSON by WireMock's gRPC extension, they use the protobuf field name "query", not the Go field name "Query". Test Results: - All 11/11 tests passing (100% pass rate) ✅ - All 32/32 assertions passing ✅ - cve-nonexistent: Now correctly returns empty cluster list - cve-cluster-does-exist: Now finds cluster and checks CVE Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Fix protocol mismatch: Update curl commands from HTTP to HTTPS to match WireMock's TLS configuration - Fix test data: Change CVE-2021-44228 test to check for 'dep-004' instead of non-existent 'dep-123-log4j' - Add grpcurl as tool dependency for Dependabot tracking in e2e-tests/tools - Fix grpcurl usage in smoke-test-mock.sh to use -insecure flag and correct query format All smoke tests now pass (7/7).

Implements all 14 code review comments on PR #32: **Script Improvements:** - Use mktemp -d instead of hardcoded /tmp paths (prevents collisions) - Add SCRIPT_DIR pattern to scripts (can run from any directory) - Replace sleep with curl health check for WireMock startup - Unify nc/curl usage (consistently use curl) - Move trap to top level in run-tests.sh - Simplify smoke test results output **WireMock Infrastructure:** - Change proto descriptor extension from .pb to .dsc - Move __files symlink creation to start-mock-central.sh - Commit pre-generated 100-year TLS certificate (valid until 2126) - Eliminates keytool/openssl dependency - Simpler user experience - works immediately after clone - Update README to distinguish committed vs generated directories - Remove chmod from setup-proto-files.sh (not needed) **Test Configuration:** - Consolidate eval-mock.yaml into eval.yaml (single config) - Make CVE verification stricter for mock mode (expect specific deployment names) - Delete unused all_deployments.json fixture All changes verified with: - make mock-test (7/7 smoke tests passing) - e2e-tests (7/11 tasks passing, 32/32 assertions passing) Co-authored-by: Mladen Todorovic <mtodor@gmail.com>
- Remove unused fixtures: orchestrator_cve.json, rhsa_2024_5137.json - Remove unused scripts: proto-version.sh, generate-cert.sh - Remove empty extensions/ directory - Compact wiremock/README.md and link to upstream docs Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Changed all deployment CVE mappings from: $.query[?(@.query =~ /.*CVE-XXX.*/)] to: $[?(@.query =~ /.*CVE-XXX.*/)] The original mappings used $.query which looked for a nested array structure, but gRPC protobuf-to-JSON conversion creates a simple object with a 'query' field (lowercase). This fix ensures WireMock can properly match gRPC requests for CVE queries. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Implements automatic protoc download and installation similar to the main stackrox repo, eliminating the need for manual protoc installation. Changes: - Add protoc auto-download logic to Makefile with OS/arch detection - Downloads protoc 32.1 from GitHub releases to .proto/ directory - Update proto-generate target to depend on local protoc installation - Update generate-proto-descriptors.sh to use PROTOC_BIN env var - Add .proto/ to .gitignore - Add .proto/ cleanup to clean target - Remove manual protoc installation from wiremock-test.yml workflow Benefits: - Developers no longer need to manually install protoc - Consistent protoc version across all developers and CI - Works offline after first download - Simplified CI workflows Usage: make proto-install # Install protoc (automatic on proto-generate) make proto-generate # Generate descriptors (auto-installs protoc) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

The smoke test was failing because protoc wasn't in PATH when the script tried to generate proto descriptors. Updated the workflow to use make mock-test instead of calling the script directly, and made mock-test depend on proto-generate and mock-download to ensure all dependencies are properly handled. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The smoke test was sending an incorrect nested JSON structure:
{"query":{"query":"CVE:\"CVE-2021-44228\""}}
The correct structure per the RawQuery protobuf message is:
{"query":"CVE:\"CVE-2021-44228\""}
This matches what the actual MCP gRPC client sends and fixes the
failing CVE-2021-44228 test.

Awesome work! This is a big step for this project!
I have executed and tested it locally. It works. I would prefer that we merge this PR and then improve things in a follow-up(s). We have several things that are waiting on this functionality.
