18-18: Update GitHub Actions to v4 for better compatibility.The static analysis correctly identifies that several actions are using outdated v3 versions. Update to v4 for improved security and compatibility.
-- uses: actions/checkout@v3 +- uses: actions/checkout@v4 -- uses: actions/setup-node@v3 +- uses: actions/setup-node@v4 -- uses: actions/upload-artifact@v3 +- uses: actions/upload-artifact@v4 -- uses: actions/download-artifact@v3 +- uses: actions/download-artifact@v4Also applies to: 21-21, 60-60, 63-63, 95-95, 98-98, 110-110, 121-121, 124-124, 129-129, 133-133, 140-140, 150-150
🧹 Nitpick comments (17)
.env.test (1)
1-18: LGTM: Well-structured test environment configuration.The test environment configuration properly isolates test settings from production, uses appropriate test ports, and includes all necessary configuration for the test infrastructure.
Consider adding a comment about the test API key being safe for testing environments:
# Test MCP Configuration +# Safe test API key - not for production use TEST_MCP_API_KEY=test-api-key-12345src/tests/fixtures/test-data.cypher (1)
1-29: LGTM! Well-structured test data with good coverage.The Cypher test data provides a comprehensive foundation for integration tests with proper entity relationships and realistic data patterns. The use of
datetime()anddate()functions ensures dynamic timestamps for testing.Consider adding test data with edge cases (e.g., users with special characters in names, projects with null/empty fields) to improve test coverage robustness.
src/config/index.ts (1)
20-30: Consider adding configuration validation.The multi-tenancy configuration structure is well-organized and follows the existing pattern. However, consider adding validation for critical configuration values to prevent runtime errors.
For example, validate that required fields are present when multi-tenancy is enabled:
multiTenancy: { enabled: process.env.ENABLE_MULTI_TENANCY === 'true', authMode: process.env.MULTI_TENANT_AUTH_MODE || 'api-key', bearer: { jwksUri: process.env.BEARER_JWKS_URI || '', issuer: process.env.BEARER_ISSUER || '', algorithm: process.env.BEARER_ALGORITHM || 'RS256', audience: process.env.BEARER_AUDIENCE || '', }, tenantGraphPrefix: process.env.TENANT_GRAPH_PREFIX === 'true', + // Validate configuration when multi-tenancy is enabled + get isValid() { + if (!this.enabled) return true; + if (this.authMode === 'bearer') { + return this.bearer.jwksUri && this.bearer.issuer; + } + return true; + } },docker-compose.test.yml (1)
22-28: Complete infrastructure setup with missing newline.The volume and network configuration provide proper isolation for test environments. However, the file is missing a newline at the end.
networks: test-network: driver: bridge +src/middleware/bearer.middleware.ts (1)
38-38: Consider usingundefinedinstead ofvoidin the return type.The static analysis tool correctly identifies that
voidcan be confusing in a union type. While this is a common pattern in Express middleware, usingundefinedwould be clearer.-public async validateJWT(req: TenantRequest, res: Response, next: NextFunction): Promise<Response<any, Record<string, any>> | void> { +public async validateJWT(req: TenantRequest, res: Response, next: NextFunction): Promise<Response<any, Record<string, any>> | undefined> {src/services/tenant-graph.service.ts (1)
3-91: Consider refactoring to plain functions instead of a static class.Since this class contains only static methods, it would be simpler to export plain functions. This aligns with functional programming practices and addresses the static analysis warning.
-export class TenantGraphService { - static resolveGraphName(graphName: string, tenantId?: string): string { +export function resolveGraphName(graphName: string, tenantId?: string): string {And update the internal call:
-const resolvedGraphName = this.resolveGraphName(graphName, tenantId); +const resolvedGraphName = resolveGraphName(graphName, tenantId);.github/workflows/node.yml (1)
42-42: Fix YAML formatting issues.Remove trailing spaces and fix indentation for better consistency.
Line 51 should have 8 spaces instead of 10 for proper indentation:
- - 6380:6379 + - 6380:6379Also applies to: 51-51, 61-61, 67-67, 70-70, 73-73, 78-78, 96-96, 102-102, 105-105, 108-108, 128-128
src/tests/integration/falkordb.integration.test.ts (2)
33-34: Avoid hardcoded test configuration values.The test assumes specific values for the test configuration. Consider making the test more flexible by not asserting exact values.
-// Verify we're connected to the test database -expect(testConfig.falkorDB.port).toBe(6380); -expect(testConfig.falkorDB.host).toBe('localhost'); +// Verify we have valid test configuration +expect(testConfig.falkorDB.port).toBeDefined(); +expect(testConfig.falkorDB.host).toBeDefined();
156-158: Improve test cleanup handling.Setting
testGraphNameto an empty string is a workaround. Consider a cleaner approach using a flag or try-catch in afterEach.-// Clear testGraphName to avoid double cleanup -testGraphName = ''; +// Mark as already cleaned up +const alreadyDeleted = testGraphName; +testGraphName = ''; +// afterEach will now skip deletion since testGraphName is emptyOr modify afterEach to handle this gracefully:
afterEach(async () => { - if (testGraphName) { + if (testGraphName) { + try { await testDbHelper.deleteTestGraph(testGraphName); + } catch (error) { + // Graph may have been deleted in test + } } });src/tests/integration/feature-comparison.integration.test.ts (1)
322-322: Consider removing or conditionalizing the console.log statement.Test output should generally be controlled by the test runner. Consider removing this line or making it conditional on a debug flag.
- console.log(`Performance comparison: Legacy=${legacyAvg.toFixed(2)}ms, Multi-tenant=${multiTenantAvg.toFixed(2)}ms, Ratio=${performanceRatio.toFixed(3)}`); + // Uncomment for debugging performance comparisons + // console.log(`Performance comparison: Legacy=${legacyAvg.toFixed(2)}ms, Multi-tenant=${multiTenantAvg.toFixed(2)}ms, Ratio=${performanceRatio.toFixed(3)}`);src/services/falkordb.service.ts (1)
33-60: Consider edge cases in array and object handling.The
escapeValuemethod converts objects within arrays and standalone objects to JSON strings. This might not always match user expectations for Cypher queries, as some users might expect property maps instead of JSON strings.Consider documenting this behavior clearly or providing an option to handle objects differently:
if (Array.isArray(value)) { - // FalkorDB only supports arrays of primitives + // FalkorDB only supports arrays of primitives - objects are converted to JSON strings const primitiveValues = value.map(v => { if (typeof v === 'object' && v !== null) { + // Consider warning users about this conversion return JSON.stringify(v); // Convert objects to JSON strings } return v; });src/tests/integration/api.integration.test.ts (1)
258-276: Consider making the non-existent graph test more deterministic.The test expects either 200 or 500 status codes when querying a non-existent graph, which could lead to flaky tests if FalkorDB's behavior changes between versions.
Consider using a more deterministic approach:
test('should handle non-existent graph', async () => { + // Ensure the graph doesn't exist before testing + const nonExistentGraph = 'non_existent_graph_12345'; + await testDbHelper.deleteTestGraph(nonExistentGraph).catch(() => {}); + const response = await request(app) .post('/api/mcp/context') .set('x-api-key', testConfig.apiKey) .send({ - graphName: 'non_existent_graph_12345', + graphName: nonExistentGraph, query: 'MATCH (n) RETURN n' }); - // FalkorDB creates graphs on first access, so this might succeed with empty results - // or fail depending on the implementation - expect([200, 500]).toContain(response.status); + // With auto-creation, expect 200 with empty results + expect(response.status).toBe(200); if (response.status === 200) { expect(response.body.data.data).toHaveLength(0); - } else { - expect(response.body).toHaveProperty('error'); } + + // Clean up if graph was created + await testDbHelper.deleteTestGraph(nonExistentGraph).catch(() => {}); });src/tests/integration/tenant-isolation.integration.test.ts (1)
163-167: Simplify the empty results assertion for better readability.The multi-condition check for empty results is thorough but could be more readable.
Consider extracting to a helper or simplifying:
- // Should return empty results because tenant2's data doesn't exist in tenant1's graph - const resultData = crossTenantAttempt.body.data; - expect(!resultData || !resultData.records || resultData.records.length === 0).toBe(true); + // Should return empty results because tenant2's data doesn't exist in tenant1's graph + const resultData = crossTenantAttempt.body.data; + const records = resultData?.records || []; + expect(records).toHaveLength(0);src/tests/integration/configuration-edge-cases.integration.test.ts (1)
27-39: Replace delete operators with undefined assignments for better performance.Static analysis correctly identified that using
deletecan impact performance. In test cleanup, setting toundefinedis more efficient.Apply this pattern throughout the file:
afterEach(async () => { await testDbHelper.clearAllTestGraphs(); // Clean up environment variables - delete process.env.ENABLE_MULTI_TENANCY; - delete process.env.MULTI_TENANT_AUTH_MODE; - delete process.env.TENANT_GRAPH_PREFIX; - delete process.env.BEARER_JWKS_URI; - delete process.env.BEARER_ISSUER; - delete process.env.BEARER_ALGORITHM; - delete process.env.BEARER_AUDIENCE; + process.env.ENABLE_MULTI_TENANCY = undefined; + process.env.MULTI_TENANT_AUTH_MODE = undefined; + process.env.TENANT_GRAPH_PREFIX = undefined; + process.env.BEARER_JWKS_URI = undefined; + process.env.BEARER_ISSUER = undefined; + process.env.BEARER_ALGORITHM = undefined; + process.env.BEARER_AUDIENCE = undefined; process.env.MCP_API_KEY = 'test-api-key'; jest.resetModules(); });Apply the same pattern to lines 44-50.
src/tests/utils/test-helpers.ts (1)
89-93: Use specific error type instead ofany.Using
anytype reduces type safety. Consider usingunknownand proper type guards.- } catch (error: any) { + } catch (error: unknown) { // Graph might not exist or be empty, that's okay for cleanup - console.log(`Graph ${graphName} deletion skipped:`, error?.message || error); + const errorMessage = error instanceof Error ? error.message : String(error); + console.log(`Graph ${graphName} deletion skipped:`, errorMessage); }src/tests/integration/api-contract-validation.integration.test.ts (2)
460-463: Remove or document the undefined parameter test case.In JSON serialization,
undefinedvalues are typically omitted from the payload. This test case might not test what's intended.Either remove the undefined test or add a comment explaining the expected behavior:
{ name: 'Null and undefined parameters', - params: { nullParam: null, undefinedParam: undefined } + params: { nullParam: null } + // Note: undefined values are omitted in JSON serialization },
537-607: Excellent backward compatibility validation approach.The test effectively validates API contract consistency across different configuration scenarios. Consider adding an
afterAllhook for final cleanup if needed.

138-140: LGTM: Proper exclusion of tool-specific configuration files.Adding Claude Code configuration files to
.gitignoreis a good practice to prevent environment-specific and potentially sensitive configuration from being tracked in version control.src/models/mcp.types.ts (1)
5-9: LGTM: Well-designed interface extension for multi-tenancy support.The
TenantRequestinterface cleanly extends Express'sRequestwith an optionaltenantIdproperty, supporting tenant-aware request handling while maintaining backward compatibility.src/services/falkordb.service.test.ts (1)
70-71: LGTM: FalkorDBService parameter substitution logic confirmedI’ve verified that
FalkorDBServiceimplements bothescapeValueandsubstituteParameters, and thatexecuteQueryuses this substitution before invokinggraph.query. The updated test correctly reflects this behavior and covers the Unicode handling fix.src/controllers/mcp.controller.test.ts (2)
94-95: LGTM: Test expectation updated to match new method signature.The test correctly expects the new signature of
executeQuerywith the tenant ID parameter (undefined for non-tenant scenarios).
120-120: LGTM: Test expectation updated for listGraphs signature.The test correctly expects the new signature of
listGraphswith the tenant ID parameter.src/tests/integration/jest.env.js (2)
10-17: Good multi-tenancy test configuration.The environment variables are properly configured for bearer token authentication testing. The hardcoded values are appropriate for test environments and won't pose security risks.
19-24: Useful optional logging control.The conditional console logging disabling is a good feature for cleaner test output while maintaining the ability to enable logging when needed for debugging.
jest.config.js (3)
6-6: Good addition of display name for clarity.The display name helps distinguish between unit and integration test runs, especially useful in CI/CD environments.
15-19: Proper test isolation configuration.The exclusion of integration tests from unit test runs ensures proper test separation and faster unit test execution.
32-33: Enhanced coverage reporting configuration.The dedicated coverage directory and multiple reporters provide better visibility into test coverage for unit tests specifically.

•validateJWTfound insrc/middleware/bearer.middleware.ts(line 38) andbearerMiddlewareexported on line 86.src/tests/utils/mock-falkordb-service.ts (5)
4-10: Good test service initialization pattern.The class structure with private client and constructor-based initialization is well-designed for test utilities.
11-31: Robust connection handling with retry logic.The async initialization with retry mechanism (5-second delay) is appropriate for test environments where services might not be immediately available. The ping test confirms connection health.
33-47: Comprehensive query execution with security consideration.The query execution method includes proper error handling and graph name sanitization to prevent log injection attacks. The parameter support aligns with the main service.
49-68: Complete service interface coverage.The
listGraphsandclosemethods provide full coverage of the FalkorDB service interface needed for testing, with consistent error handling patterns.
70-70: Singleton pattern appropriate for test utility.Exporting a single instance is appropriate for test utilities, ensuring consistent state across test files.

Filtering logic makes assumptions about underscore usage.
The current implementation assumes any graph containing an underscore is tenant-prefixed, which could incorrectly filter legitimate non-tenant graphs with underscores in their names.
Consider using a more specific pattern check:
-return allGraphs.filter(graphName => !graphName.includes('_'));
+// Only filter graphs that match tenant prefix pattern (e.g., "tenantId_graphName")
+return allGraphs.filter(graphName => {

In src/services/tenant-graph.service.ts around lines 69 to 71, the filtering
logic incorrectly assumes any graph name containing an underscore is
tenant-prefixed, which may exclude valid non-tenant graphs. Update the filter to
use a more specific pattern that accurately identifies tenant-prefixed graphs,
such as checking if the graph name starts with the tenantId followed by an
underscore, instead of just checking for any underscore.

Add parameter name validation to prevent regex issues.
The substituteParameters method uses parameter names directly in regex patterns without escaping special characters. This could cause issues if parameter names contain regex metacharacters.
Add validation or escaping for parameter names:
private substituteParameters(query: string, params?: Record<string, any>): string {
if (!params) {
return query;
}
let substitutedQuery = query;
for (const [key, value] of Object.entries(params)) {

Consider the implications of singleton pattern for parallel test execution.
The singleton testDbHelper instance could cause issues if tests run in parallel, as they would share the same database connection. This might lead to race conditions or test interference.
Verify if tests are configured to run sequentially:
Consider either ensuring tests run sequentially or creating separate helper instances per test suite if parallel execution is needed.
🏁 Script executed:
#!/bin/bash
# Description: Check Jest configuration for parallel execution settings
# Look for Jest configuration files
fd -e js -e json "jest.config" | head -10
# Check for maxWorkers or runInBand settings
rg "maxWorkers|runInBand" --glob "jest.config*" --glob "package.json"Length of output: 153
Ensure test helper isolation or enforce sequential test execution
Our inspection found two Jest configuration files (jest.config.js, jest.config.integration.js) with no runInBand or maxWorkers overrides, so Jest will run tests in parallel by default. The exported singleton testDbHelper will be shared across concurrent test suites, risking race conditions or graph‐naming collisions.
Recommended actions:
- Either enforce sequential test runs by adding
runInBand: true(or settingmaxWorkers: 1) in your Jest config or test scripts. - Or refactor
TestDatabaseHelperso each test suite gets its own instance (e.g. export a factory function instead of a singleton). - Additionally, consider namespacing test graphs (e.g. include a unique test ID) to avoid cross‐suite interference.

In src/tests/utils/test-helpers.ts around lines 31 to 118, the exported
singleton instance testDbHelper is shared across parallel Jest test suites,
causing potential race conditions and graph name collisions. To fix this,
refactor the code to export a factory function that creates a new
TestDatabaseHelper instance for each test suite instead of a singleton.
Additionally, modify graph naming in methods like createTestGraph and
deleteTestGraph to include a unique identifier (e.g., a test-specific ID or
timestamp) to namespace test graphs and prevent cross-suite interference.
Alternatively, update Jest configuration to enforce sequential test execution by
setting runInBand: true or maxWorkers: 1.

🛠️ Refactor suggestion
Make tenant ID expectations explicit in the test.
The test expects tenant ID 'test-tenant-123' but it's not clear where this value comes from. This creates a fragile test that relies on implicit mock behavior.
Consider making the expected behavior more explicit:
+ // Set up explicit mock behavior for this test
+ const mockValidateJWT = require('../../middleware/bearer.middleware').bearerMiddleware.validateJWT;
+ mockValidateJWT.mockImplementationOnce((req) => {
+ req.user = { tenantId: 'test-tenant-123' };
+ return true;
+ });
+
// Test graphs endpoint response includes tenant information
const graphsResponse = await request(app)
.get('/api/mcp/graphs')
.set('Authorization', 'Bearer test-jwt');📝 Committable suggestion

Configure the bearer middleware mock with expected behavior.
The mock is created but not configured with any return values or behavior. Tests relying on bearer token validation might pass even if the real implementation is broken.

By default validateJWT: jest.fn() neither calls next() nor populates req.tenantId, so any tests that run under
config.multiTenancy.enabled === true && authMode === 'bearer' will either hang or run with an undefined tenant.

Apply a mock implementation that:
- Checks for a Bearer header (or skips if you prefer a “happy-path” stub)

req.tenantIdto a fixed test value - Calls
next()to continue the chain
