MCP server for Snyk API & Web (Probely) — create targets, run scans, manage findings

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, Windsurf, 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+
• 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)

Install directly from the Cursor Marketplace:

1. Open Cursor and go to Settings → Plugins
2. Search for Snyk API & Web
3. Click Install
4. Set your API key as an environment variable:

   export MCP_SAW_API_KEY="your-api-key"
   

The plugin installs the MCP server, rules, and skills 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 <version> 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.

4. Configure Your IDE

If you installed from the Cursor 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).

5. 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 for a full catalog of example prompts — from simple one-liners to complex multi-target workflows.

IDE Integration

Detailed per-host guides live in docs/installation-guides/:

Host	Guide
Cursor	install-cursor.md
Windsurf	install-windsurf.md
Claude Desktop	install-claude.md
Devin / Other IDEs	install-devin.md

Packaging

bash scripts/package.sh

Creates dist/SnykAPIWeb-<version>.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
