MAIN ASPECTS

The ai is not human, we should simplify it and we can make it understand the prompt clearly for some regular tasks. Managing human behavior is not easy. We should not let the ai to behave like a human and to make the prompt processing difficult. We should let the ai to do its job and to make it understand the prompt clearly in regular cases. We must reduce the token usage. Otherwise it will be expensive.

Node.js MCP Server

A specialized MCP server focused on 3 Core Jobs for agentic workflows.

The 3 Jobs

1. Context Management & Learning

The agent can manage the project's documentation and "learn" the entire context.

Tool: md
Actions:
- read_all: Reads README.md from the specified path.
- update_all: Overwrites/updates README.md with new content provided by the client.
- Arguments:
  - path (string, optional) - Absolute path to project root.
  - content (string, required for update_all) - The new content for README.md.

2. Test Management

The agent can manage the project's tests in a unified workflow.

Tool: test
Action: test
Functionality:
1. Writes the provided test code to test_path.
2. Runs the project's test suite (npm test).
3. Reports output and errors to test.md.
Arguments:
- path (string, optional) - Absolute path to project root.
- test_path (string, required) - Relative path to the test file (e.g., tests/api.test.js).
- code (string, required) - Content of the test file.

3. Build & Run

Tool: deploy
Actions:
- dev: Runs the project in development mode.
- prod: Builds the project and runs it.
- Arguments:
  - path (string, optional) - Absolute path to project root.

Installation & Usage

1. Build the Server

cd /home/mc/Desktop/mcpserver
npm install
npm run build

2. Configuration (Claude / Antigravity)

Add to your MCP configuration file:

Location: ~/.config/Claude/claude_desktop_config.json (Linux)

{
  "mcpServers": {
    "job-server": {
      "command": "node",
      "args": ["path/to/mcpserver/dist/index.js"]
    }
  }
}

{
  "mcpServers": {
    "my-job-server": {
      "command": "node",
      "args": ["path/to/mcpserver/dist/index.js"]
    }
  }
}

3. Usage Examples

Manage Tests

To create a test, update it, or simply run existing tests (by re-submitting the code), use the test tool.

{
  "name": "test",
  "arguments": {
    "action": "test",
    "path": "path/to/ServiceApp",
    "test_path": "tests/login.test.js",
    "code": "describe('Login', () => { ... });"
  }
}

The server will:

Save tests/login.test.js.
Run npm test.
Report full results to test.md.

Troubleshooting

Path Issues: Always provide the path argument.
npm test: The test action requires a valid test script in the project's package.json.
