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 β 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 newSAW/sawnaming.
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
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 β .env file β config/config.yaml.
Option A: Environment variable (recommended for 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
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 theenvblock. - 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 β 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
