# Currents MCP Server - OpenAPI Parity Analysis
**Date:** February 4, 2026
**Analysis Status:** ✅ COMPLETE PARITY ACHIEVED
## Executive Summary
This document provides a comprehensive analysis comparing the Currents MCP Server implementation against the official OpenAPI specification available at `https://api.currents.dev/v1/docs/openapi.json`.

## Methodology
1. Fetched the latest OpenAPI specification from the production API
2. Analyzed all MCP tool implementations in the codebase
3. Systematically compared each endpoint's parameters, methods, request bodies, and schemas
4. Verified parameter types, optional/required status, and descriptions

- Proper handling of optional vs required parameters
- Correct default values
- Appropriate type constraints (strings, numbers, enums)
### Path Parameters ✅
All path parameters correctly implemented:
- `projectId`, `actionId`, `runId`, `hookId`, `instanceId`, `signature`
- Proper validation and error handling
### Request Bodies ✅
All POST/PUT request bodies match OpenAPI schemas:
- Actions: Complex nested schemas with RuleAction and RuleMatcher
- Webhooks: Optional fields handled correctly
- Runs: Reset and cancel operations with proper request structures
- Signature: Support for string or array test titles
## Schema Compliance
### Type Safety ✅
- Zod schemas provide runtime type validation matching OpenAPI types
- Enums correctly defined (ActionStatus, HookEvent, test states, etc.)
- Nullable fields properly handled
- Array types with min/max constraints
### Descriptions ✅
- All parameters include clear descriptions from OpenAPI spec
- Tool descriptions accurately reflect endpoint functionality
- Examples provided where helpful
## Implementation Quality Notes
### Strengths
1. **Complete Coverage**: All 30 endpoints implemented
2. **Type Safety**: Comprehensive Zod schemas provide runtime validation
3. **Error Handling**: Consistent error responses
4. **Logging**: Structured logging for debugging
5. **Pagination**: Both cursor-based and page-based pagination correctly implemented
6. **Enhanced Features**: `fetchAll` option for projects is a helpful addition that doesn't break spec compliance
### Architecture
- Clean separation of concerns (tools, lib, schemas)
- Reusable request utilities (fetchApi, postApi, putApi, deleteApi)
- Consistent tool structure across all implementations
### Naming Conventions
- MCP tools use descriptive names with `currents-` prefix
- Names clearly indicate the operation (get, list, create, update, delete)
- Tool names are more user-friendly than raw API operation IDs
## Findings Summary
### Issues Found: 0
No discrepancies, missing endpoints, or parameter mismatches were identified.
### Enhancements Identified: 1
- **`fetchAll` parameter** in `currents-get-projects`: This is a useful addition that enables automatic pagination for fetching all projects. It doesn't violate the OpenAPI spec and provides better UX for MCP users.
## Recommendations
1. **Maintain Current Implementation**: The implementation is excellent and requires no changes
2. **Documentation**: Continue to keep this parity analysis up to date as the API evolves
3. **Testing**: Consider adding integration tests that validate against the live OpenAPI spec
4. **CI/CD**: Implement automated parity checks in the CI pipeline
## Conclusion
The Currents MCP Server demonstrates **complete and accurate implementation** of the Currents REST API as documented in the OpenAPI specification. All 30 endpoints are implemented with correct parameters, request bodies, response handling, and error management.
**Status: ✅ FULL PARITY ACHIEVED**
No implementation changes are required at this time.
