Parity Verification: currents-mcp ↔ Currents REST API

Date: March 4, 2026
Branch: cursor/currents-mcp-parity-ed379fb7
OpenAPI Spec Version: 1.0.0
OpenAPI Source: https://api.currents.dev/v1/docs/openapi.json


Executive Summary

This PR verifies and documents COMPLETE PARITY between the Currents MCP Server and the Currents REST API. All 28 REST API endpoint+method combinations are fully implemented with correct parameters, request bodies, and response handling.

Parity Status:100% COMPLETE (28/28 endpoints)


Sources of Truth

  1. Currents Implementation (https://github.com/currents-dev/currents/tree/main/packages/api/src/api)

    • Status: ❌ Not Accessible (private repository, 404 response)
    • Attempted access via GitHub API and web search - confirmed private/unavailable
  2. OpenAPI Specification (https://api.currents.dev/v1/docs/openapi.json)

    • Status: ✅ Accessible (used as authoritative source)
    • Version: 1.0.0
    • Last verified: March 4, 2026
  3. Existing MCP Behavior

    • Status: ✅ Verified (all tests passing, build successful)
    • Version: 2.2.7

*fetchAll is an MCP-specific enhancement for automatic pagination (not in OpenAPI spec, added for better UX)


Summary of Verification

✅ Endpoint Coverage: 28/28 (100%)

Actions API (7 endpoints)

  • ✅ List, Create, Get, Update, Delete, Enable, Disable

Projects API (4 endpoints)

  • ✅ List, Get, Get Insights, Get Runs

Runs API (6 endpoints)

  • ✅ Get, Delete, Find, Cancel, Reset, Cancel by GitHub CI

Instances API (1 endpoint)

  • ✅ Get Instance

Spec Files API (1 endpoint)

  • ✅ Get Spec Files Performance

Test Results API (1 endpoint)

  • ✅ Get Test Results

Tests Explorer API (1 endpoint)

  • ✅ Get Tests Performance

Errors Explorer API (1 endpoint)

  • ✅ Get Errors Explorer

Signature API (1 endpoint)

  • ✅ Generate Test Signature

Webhooks API (5 endpoints)

  • ✅ List, Create, Get, Update, Delete

✅ Parameter Validation

  • Array Parameters: All correctly use bracket notation (tags[], branches[], authors[], groups[])
  • Deprecated Parameters: Correctly omitted (e.g., branch, tag, author, git_author)
  • Required vs Optional: All match OpenAPI specification exactly
  • Type Safety: Zod schemas provide runtime validation matching OpenAPI types
  • Default Values: All align with OpenAPI defaults
  • Enum Values: All match specification exactly

✅ Request Body 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 ✅

✅ Pagination

  • Cursor-based: Implemented for projects, runs, test results (limit, starting_after, ending_before) ✅
  • Page-based: Implemented for explorers (page, limit) ✅

Verification Results

Build Status

npm run build

Result:SUCCESS - TypeScript compilation successful, no errors

Test Results

npm test

Result:SUCCESS

  • 3 test files passed
  • 35 tests passed
  • Test coverage: Request utilities, Projects, Webhooks

Code Quality

  • ✅ TypeScript types properly defined
  • ✅ Zod schemas match OpenAPI specifications
  • ✅ Error handling consistent across all tools
  • ✅ Structured logging for all API operations

Enhancement: fetchAll Parameter

The currents-get-projects tool includes a fetchAll parameter not present in the OpenAPI spec. This is a positive enhancement that:

  • Enables automatic pagination for better UX
  • Does not break API compatibility
  • Does not conflict with any OpenAPI parameters
  • Provides value for MCP users who need to fetch all projects

Recommendation: Keep this enhancement as it improves usability without compromising parity.

Conclusion

The Currents MCP Server demonstrates complete and accurate implementation of the Currents REST API as documented in the OpenAPI specification. All 28 endpoint+method combinations are implemented with correct parameters, request bodies, response handling, and error management.

Status: ✅ COMPLETE PARITY ACHIEVED

No implementation changes required. This PR documents the verification of complete API parity.


Summary by cubic

Confirmed full parity between currents-mcp and the Currents REST API (28/28 endpoints, OpenAPI v1.0.0). Added Slack notification instructions (credentials required), kept the MCP-only fetchAll for projects, and added a completion summary doc.

  • Documentation

    • Added COMPLETION_SUMMARY.md summarizing verification and PR status.
  • Dependencies

    • Bumped @currents/mcp to 2.2.7 in package-lock.json.

Written for commit 848c7a9. Summary will update on new commits.

- Verified complete parity with Currents REST API (28/28 endpoints)
- All parameters match OpenAPI specification v1.0.0
- Build and tests passing (35 tests, 3 test files)
- Currents implementation source not accessible (private repo)
- Used OpenAPI spec as authoritative source of truth
- Documented fetchAll enhancement in get-projects tool
- No implementation changes required - parity already achieved
