Snyk API & Web MCP Server

Connect your AI coding assistant to Snyk API & Web so it can onboard scan targets, configure authentication, run DAST scans, and triage findings — all through natural language.

Built on FastMCP 2.0, works with Cursor, Claude Code, Devin, and any MCP-compatible client.

Naming note: Snyk API & Web was formerly known as Probely. The API endpoints (api.probely.com), web console (plus.probely.app), and MCP tool names (probely_*) still use the legacy domain and prefix. Environment variables and config sections use the new SAW / saw naming.

See USER_GUIDE.md for usage, examples, and tool reference.

Requirements

• Python 3.10+
• Node.js 18+ and npm (for web target login recording via playwright-cli; optional if using Playwright MCP instead)
• Snyk API & Web API key

Quick Start

1. Get Your API Key

Go to https://plus.probely.app/api-keys and create an API key.

Important

Use a custom role, limited-scope API key for the Snyk API & Web MCP Server. Create the key only with the permissions required for the intended actions. Do not use a highly privileged or global API key, as this can affect your entire account and its resources.

2. Install

Cursor Marketplace (recommended for Cursor users)

Install directly from the Cursor Marketplace:

1. Open the Snyk API & Web plugin page and click Install, or go to Settings → Plugins and search for Snyk API & Web
2. Set your API key as an environment variable before launching Cursor:

   export MCP_SAW_API_KEY="your-api-key"
   

The plugin installs the MCP server, rules, and skills automatically.

Devin MCP Marketplace (Devin users)

Install directly from Devin’s MCP Marketplace:

1. Open Devin and go to Settings → Configuration.
2. Under MCP servers, click Open MCP Marketplace.
3. Search for Snyk API & Web and click Install.
4. When prompted, enter your API key.

No manual configuration needed — Devin handles the setup automatically.

One-command install (any MCP client)

uvx --from git+https://github.com/snyk/saw-mcp.git saw-mcp

Or add to your MCP client configuration:

{
  "mcpServers": {
    "SAW": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/snyk/saw-mcp.git", "saw-mcp"],
      "env": {
        "MCP_SAW_API_KEY": "your-api-key"
      }
    }
  }
}
