Vynix MCP Server

Model Context Protocol server for Vynix. It gives coding agents direct access to visual feedback, bug reports, screenshots, diagnostics, comments, and issue workflows so agents can reason from real context instead of guessing.

Why Vynix

• Feedback with evidence: page metadata, target element, screenshot, console/network context.

• End-to-end execution: inspect feedback, diagnose, generate coding prompts, create GitHub issues, update status, comment.

• Agent-safe hints: read-only/idempotent/open-world annotations for better approval behavior in MCP clients.

• Registry-ready metadata for modern MCP directories.

Features

• 17 production tools for read and write workflows.

• Resource catalog for server metadata, tool/prompt/skill references, and contextual summaries.

• Workflow prompts for QA, release readiness, PM briefings, and engineering planning.

• Dual transport support: stdio and Streamable HTTP.

• Auth via API token or email/password refresh flow.

Installation

Node.js 18+ is required.

NPX (recommended)

{
  "mcpServers": {
    "vynix": {
      "command": "npx",
      "args": ["-y", "@usevynix/mcp-server"],
      "env": {
        "VYNIX_API_URL": "https://www.vynix.in",
        "VYNIX_API_TOKEN": "PASTE_YOUR_TOKEN_HERE"
      }
    }
  }
}

npm global install

npm install -g @usevynix/mcp-server
vynix-mcp

Docker

docker run --rm -i \
  -e VYNIX_API_URL=https://www.vynix.in \
  -e VYNIX_API_TOKEN=PASTE_YOUR_TOKEN_HERE \
  ghcr.io/usevynix/vynix-mcp:latest

Local development

git clone https://github.com/UseVynix/vynix-mcp.git
cd vynix-mcp
npm install
npm run build
npm run check
node dist/index.js

Client Configuration

Claude Desktop

Use claude_desktop_config.json:

{
  "mcpServers": {
    "vynix": {
      "command": "npx",
      "args": ["-y", "@usevynix/mcp-server"],
      "env": {
        "VYNIX_API_TOKEN": "PASTE_YOUR_TOKEN_HERE"
      }
    }
  }
}

Diagnostics are written to stderr; stdout is reserved for the protocol stream.

Cursor

Use ~/.cursor/mcp.json.

{
  "mcpServers": {
    "vynix": {
      "command": "npx",
      "args": ["-y", "@usevynix/mcp-server"],
      "env": {
        "VYNIX_API_TOKEN": "PASTE_YOUR_TOKEN_HERE"
      }
    }
  }
}

VS Code

Use .vscode/mcp.json with top-level servers:

{
  "servers": {
    "vynix": {
      "command": "npx",
      "args": ["-y", "@usevynix/mcp-server"],
      "env": {
        "VYNIX_API_TOKEN": "PASTE_YOUR_TOKEN_HERE"
      }
    }
  }
}

Windsurf

Use your Windsurf MCP config file with this server block:

{
  "mcpServers": {
    "vynix": {
      "command": "npx",
      "args": ["-y", "@usevynix/mcp-server"],
      "env": {
        "VYNIX_API_TOKEN": "PASTE_YOUR_TOKEN_HERE"
      }
    }
  }
}

ChatGPT connectors

For hosted mode, use the Streamable HTTP endpoint:

• Base URL: https://mcp.vynix.in/mcp

• OAuth discovery: /.well-known/oauth-authorization-server

Generic mcp.json

See examples/configs/mcp.json.

Authentication

Environment variables:

• VYNIX_API_URL (optional, default: https://www.vynix.in)

• VYNIX_API_TOKEN (recommended)

• VYNIX_API_EMAIL and VYNIX_API_PASSWORD (fallback login mode)

• VYNIX_MCP_MODE (stdio or http)

• VYNIX_MCP_HOST, VYNIX_MCP_PORT, VYNIX_MCP_PATH (HTTP mode)

Generate a token from: https://www.vynix.in/mcp

Troubleshooting

• Not configured error: set VYNIX_API_TOKEN or both VYNIX_API_EMAIL and VYNIX_API_PASSWORD.

• 401 errors: regenerate token and verify API URL.

• No tools listed: confirm the MCP config key (mcpServers vs servers) for your client.

• Hosted mode not reachable: verify VYNIX_MCP_MODE=http and check /health.

FAQ

Does this send data to third-party AI providers?

Only diagnose_annotation can invoke external AI providers through your Vynix workspace configuration.

Is this read-only?

No. It includes read tools and write tools. MCP annotations identify mutating/open-world calls so clients can request confirmation.

Can I self-host?

Yes. Run in stdio mode locally or HTTP mode behind your own infrastructure.

Security

• Never commit API tokens.

• Prefer short-lived tokens where possible.

• See SECURITY.md (create one if your org requires a disclosure policy).
