Overview

Description from the maker (original English)

MCP server for Snyk API & Web — DAST scanning, findings management, and vulnerability triage

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Cybersecurity
  • You need to fill in: MCP_SAW_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: MCP_SAW_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "saw": {
      "command": "uvx",
      "args": [
        "snyk-apiweb-mcp"
      ],
      "env": {
        "MCP_SAW_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add saw --env MCP_SAW_API_KEY=your-value -- uvx snyk-apiweb-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "saw": {
      "command": "uvx",
      "args": [
        "snyk-apiweb-mcp"
      ],
      "env": {
        "MCP_SAW_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "saw": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "snyk-apiweb-mcp"
      ],
      "env": {
        "MCP_SAW_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Snyk API & Web MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MCP_SAW_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.2) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

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](USER_GUIDE.md) for usage, examples, and tool reference.

This repository is closed to public contributions. We appreciate community interest, but we do not accept pull requests, issues, or other contributions from external contributors at this time. If you have found a security issue, please see SECURITY.md.

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" } } } }

Alternative installation methods

Install from release tarball

tar -xzvf SnykAPIWeb-<version>.tgz

cd SnykAPIWeb python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate pip install -r requirements.txt

Download from Releases and replace with the actual version number (e.g., 1.0.0).

Clone from source

git clone https://github.com/snyk/saw-mcp.git

cd saw-mcp python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate pip install -r requirements.txt

3. Store Your API Key

The server reads your API key from (in order of precedence): environment variable MCP_SAW_API_KEY → .env file → config/config.yaml.

Option A: Environment variable (recommended for Marketplace / uvx installs)

export MCP_SAW_API_KEY="your-api-key"

Option B: `.env` file (recommended for source installs)

Run the setup script (prompts securely, no key in shell history):

./scripts/setup-env.sh

Or pipe from a secret manager: op read 'op://vault/item/key' | ./scripts/setup-env.sh

This writes a .env file in the project root (gitignored). The server loads it automatically at startup.

Option C: Secret reference (avoids storing the key in plaintext anywhere)

MCP_SAW_API_KEY and the config api_key field also accept a reference that is resolved at runtime, so the literal key never sits in a file:

export MCP_SAW_API_KEY="op://vault/saw-mcp/api-key"   # resolved via the 1Password CLI (`op`)

export MCP_SAW_API_KEY="env:MY_SAW_KEY" # read from another environment variable

Avoid committing a plaintext key. config/config.yaml is gitignored, and a plaintext key read from it logs a warning at startup.

4. Install Browser Automation (web targets with login)

Web target onboarding records login sequences in a real browser. Preferred for coding agents: playwright-cli via Shell:

npm install -g @playwright/cli@latest

playwright-cli install-browser chromium

Or run ./scripts/setup-playwright.sh from a cloned repo.

Alternative: install Playwright MCP as a second MCP server (better for MCP-only clients without Shell). See Web target prerequisites.

5. Configure Your IDE

If you installed from the Cursor or Devin marketplace, configuration is automatic. For other clients, 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" } } } }

For host-specific setup see the Installation Guides.

Additional configuration options

  • Override the base URL: add "MCP_SAW_BASE_URL": "https://your-instance-url" to the env block.
  • Use a config file: set "MCP_SAW_CONFIG_PATH": "/path/to/config.yaml" instead.
  • Set log level: add "MCP_SAW_LOG_LEVEL": "DEBUG" (options: DEBUG, INFO, WARNING, ERROR, CRITICAL; default: INFO).
6. Start Using

Ask your AI assistant to:

  • "Configure a Snyk API & Web API target from this OpenAPI schema / Swagger document / Postman collection."
  • "Configure a Snyk API & Web web target for this authenticated application."

See [prompts.md](prompts.md) for a full catalog of example prompts — from simple one-liners to complex multi-target workflows.

Web target prerequisites

The SAW MCP server talks to the Snyk API & Web platform — it does not include a browser. To onboard web targets with login sequences, the AI needs browser automation via one of:

PathBest forSetup
`playwright-cli` (preferred)Cursor, Devin, Claude Code, Cloud Agents with Shellnpm install -g @playwright/cli@latest && playwright-cli install-browser chromium
[Playwright MCP](https://playwright.dev/docs/getting-started-mcp) (fallback)MCP-only clients without Shell (e.g. Claude Desktop)Add Playwright MCP to your IDE's MCP config

Workflow:

  1. Prompt with the target URL and credentials — e.g. *"Add target example.com with credentials user@example.com / password123"*.
  2. The AI records the login in a browser (playwright-cli or Playwright MCP).
  3. SAW MCP tools create the target and upload the sequence in the Probely sequence-recorder format.

Without browser automation, the AI falls back to form login (probely_configure_form_login) — simple single-page login only; no multi-step flows or 2FA.

See the Cursor installation guide for setup details.

Packaging

bash scripts/package.sh

Creates dist/SnykAPIWeb- .tgz (version from snyk_apiweb/__init__.py).

Development & Testing

Run the Server (standalone)

Running the server directly starts it and waits for an MCP client connection. This is mainly useful for development and debugging:

./venv/bin/python -m snyk_apiweb.server
Development Mode (hot reload)

For active development with automatic reload on file changes:

./scripts/dev.sh
