Currents MCP Server

This is a MCP server that allows you to provide test results context to your AI agents by connecting them to Currents. Useful for asking AI to fix or optimize tests failing in CI.

⚠️ Notice

By connecting AI tools (e.g., via MCP) to Currents, you are granting them access to your API key, test results and CI metadata. It is your responsibility to vet any AI agents or services you use, and to ensure they handle your data securely.

How to Contribute

We welcome contributions of all kinds—bug fixes, features, and documentation updates!

Quick Start

1. Fork this repository and clone your fork:

   git clone https://github.com/<your-username>/currents-mcp.git
   cd currents-mcp
   

2. Install dependencies:

   cd mcp-server
   npm install
   

3. Build the project:

   npm run build
   

4. Run tests:

   npm test
   

   See TESTING.md for more details on testing.
5. Run locally (stdio):

   npm start
   

   You should see: Currents MCP Server running on stdio.

Local Development with a Client (optional)

To test with a local MCP client (e.g., Cursor or Claude Desktop), point the client to your built server:

• Command: node
• Args: ./mcp-server/build/index.js
• Env: set CURRENTS_API_KEY to a valid key

Example snippet for a client config:

{
  "mcpServers": {
    "currents": {
      "command": "node",
      "args": ["./mcp-server/build/index.js"],
      "env": {
        "CURRENTS_API_KEY": "your-api-key"
      }
    }
  }
}

Test tools locally

To test the tools locally without any LLM, you can use the following command:

 npm run build

then run the tools script:

 node scripts/call-tools.js

Making Changes

• Create a feature branch:

  git checkout -b feat/short-description
  

• Make changes under mcp-server/src/, then rebuild and re-run:

  npm run build && npm start
  

• Write tests for your changes in *.test.ts files alongside your code
• Run tests to ensure everything works:

  npm test
  

• Keep changes focused and documented (add comments/types where helpful).

Commit and PR Guidelines

• Write clear commit messages (e.g., “fix: handle missing env vars” or “feat: add get-run tool filters”).
• Push your branch and open a Pull Request:

  git push origin feat/short-description
  

• In your PR, describe the motivation, approach, and any trade-offs. Link related issues if applicable.

Reporting Issues

• Before creating a new issue, please search existing issues to avoid duplicates.
