+## Verification Methodology
+
+### 1. Source of Truth Analysis
+
+The verification was performed against the OpenAPI specification:
+- **URL**: `https://api.currents.dev/v1/docs/openapi.json`
+- **Date Retrieved**: 2026-02-12
+- **Total Endpoints**: 27 unique endpoint+method combinations
+
+### 2. Parameter Verification
+
+For each endpoint, the following were verified:
+- ✅ Path parameters (names, types, required/optional status)
+- ✅ Query parameters (names, types, array handling with `[]` syntax)
+- ✅ Request body schemas (for POST/PUT operations)
+- ✅ Parameter defaults and constraints (min/max values, enums)
+
+### 3. Key Findings
+
+#### Arrays and Pagination
+- All array parameters correctly use `[]` suffix syntax (e.g., `tags[]`, `branches[]`, `authors[]`)
+- Cursor-based pagination properly implemented with `starting_after` and `ending_before`
+- Page-based pagination correctly used for test/spec performance endpoints
+- `fetchAll` convenience parameter added for projects endpoint (MCP enhancement)
+
+#### Request Bodies
+All POST/PUT operations verified:
+- ✅ Actions: Complex schemas with `RuleAction`, `RuleMatcher`, `ConditionType`, and `ConditionOperator` enums
+- ✅ Webhooks: url, headers (JSON string), hookEvents array, label
+- ✅ Runs: machineId array (1-63), isBatchedOr8n boolean
+- ✅ Test Signature: projectId, specFilePath, testTitle (string or array)
+
+#### Filtering and Search
+All filtering capabilities verified:
+- Status filters (actions, runs, tests)
+- Date range filters (ISO 8601)
+- Tag operators (AND/OR)
+- Search by ciBuildId and commit message
+- Git metadata filtering (branches, authors, remote origin)
+- Test state filtering (passed/failed/pending/skipped)
+
+#### Ordering and Sorting
+Correct ordering parameters for:
+- Spec files: avgDuration, failureRate, flakeRate, timeoutRate, etc.
+- Tests: failures, passes, flakiness, duration, executions, deltas
+- Direction: asc/desc
+
+---
+
+## Test Results
+
+```bash
+npm test
+```
+
+**Results**:
+- ✅ 3 test files passed
+- ✅ 35 tests passed
+- ✅ 0 tests failed
+
+Test coverage includes:
+- Request library with API error handling
+- Projects endpoint with pagination
+- Webhooks CRUD operations
+
+---
+
+## Build Verification
+
+```bash
+npm run build
+```
+
+**Results**:
+- ✅ TypeScript compilation successful
+- ✅ No type errors
+- ✅ Build artifacts generated in `build/` directory
+
+---
+
+## Implementation Quality Assessment
+
+### Strengths
+
+1. **Type Safety**: All tools use Zod schemas for runtime validation
+2. **Consistent Error Handling**: Uniform error responses across all tools
+3. **Logging**: Comprehensive logging for debugging
+4. **Documentation**: Clear descriptions for all parameters
+5. **Pagination**: Both cursor-based and page-based properly implemented
+6. **Array Handling**: Correct use of `forEach` to append array parameters
+7. **Optional Parameters**: Proper handling of undefined/optional values
+
+### MCP Enhancements (Non-Breaking)
+
+The following enhancements were added to improve MCP usability without breaking API parity:
+
+1. **`fetchAll` parameter** on `currents-get-projects`: Automatically paginates to retrieve all projects
+2. **Enhanced descriptions**: More detailed parameter descriptions for LLM consumption
+3. **Consistent naming**: All tools use `currents-*` prefix for clarity

+
+## Conclusion
+
+The `currents-mcp` server demonstrates **complete API parity** with the Currents REST API. All 27 endpoints are correctly implemented with accurate parameter schemas, request bodies, and response handling. The implementation follows best practices for type safety, error handling, and documentation.
+
+**Recommendation**: No changes required. The MCP server is production-ready and maintains full parity with the REST API.
