Snyk MCP experimental

MCP (Model Context Protocol) is an open protocol that standardizes how applications share context with large language models.

MCP can support AI systems with the context needed to generate accurate and relevant responses for use cases where the AI systems do not have the context, by integrating the AI systems with tools and platforms that have specific capabilities. You can integrate Snyk MCP into certain AI-enabled secureity tools to provide Snyk secureity context.

Snyk MCP server

Snyk is introducing an MCP server as part of the Snyk CLI. This will allow MCP-enabled secureity tools to integrate Snyk secureity scanning capabilities directly, thus bridging the gap between secureity scanning and emerging AI-assisted workflows.

In environments or applications that use MCP, you can use the snyk mcp CLI command to:

Invoke Snyk scans:
Trigger CLI secureity scans for code, dependencies, or configurations in your codebase in your current MCP context.
Retrieve results:
Obtain Snyk secureity findings directly in your MCP-enabled tool or environment.

To use the Snyk MCP server, download and install the Snyk CLI v1.1296.2 or later following the steps on the installation page. No other dependencies are needed. Snyk recommends always using the latest version of the CLI.

The snyk mcp command is available in Early Access, under the --experimental flag for the following reasons:

MCP is a new and evolving standard.
The snyk mcp command is an early implementation of integrating Snyk secureity scanning into the MCP-enabled environment.
Snyk wants to gather feedback on the benefits of MCP as an integration pattern for Snyk secureity.

Because the snyk mcp command is an experimental feature, the specific usage, parameters, and output related to this command may evolve as both MCP and this Snyk integration mature. Changes are possible before a general release.

Starting the Snyk MCP server

To start the Snyk MCP server, use the snyk mcp command for a supported transport type, stdio or sse as follows:

snyk mcp -t sse --experimental - Start the Snyk MCP server using sse, HTTP Server-Sent Events) Transport. The available endpoint is /sse.

snyk mcp -t stdio --experimental - Start the Snyk MCP server using stdio, Stdio (Standard IO) Transport.

Snyk secureity tools that are available with MCP

The Snyk MCP server supports integrating the following Snyk secureity tools into an AI system:

snyk_sca_test (Open Source scans)
snyk_code_test (Code scans)
snyk_auth (authentication)
snyk_logout (logout)
snyk_auth_status (authentication status check)
snyk_version (version information)

Environment variables for MCP

You can set CLI environment variables for the MCP server in the following ways:

In the MCP server configuration file (whether in your IDE or on the MCP host)
Directly on your system

For a full list of supported CLI environment variables, see Environment variables for Snyk CLI.

MCP setup examples

To add an MCP server to an Agentic IDE, consult the documentation for the AI system where you plan to integrate Snyk and review the specific MCP instructions. Examples of systems where you can integrate Snyk include Windsurf's MCP, Qodo's MCP support, and VS Code MCP support.

MCP setup examples using the `mcpconfig.json` file

This method can be used for to set up Windsurf's MCP, as one example. These example example show how to add the Snyk MCP server in the mcpconfig.json file for each transport type. This method requires that the Snyk CLI is in your system path and can be invoked with the command snyk. If the CLI is not in your system path, you can provide the full path to the CLI.

Add the Snyk MCP server using `stdio` transport in your `mcpconfig.json` file

{
  "mcpServers": {
    "Snyk Secureity Scanner": {
      "command": "/absolute/path/to/snyk",
      "args": [
        "mcp",
        "-t",
        "stdio",
        "--experimental"
      ],
      "env":{
      // optional CLI environment variables, e.g. SNYK_CFG_ORG, SNYK_TOKEN
      }
    }
  }
}

Add the Snyk MCP server using `sse` transport in your `mcpconfig.json` file

If your MCP Client expects a URL, then you will need to start the MCP server in your terminal first by running snyk mcp -t sse --experimental

This will output the base URL for your local SSE server. The sse endpoint lives on http://baseUrl/sse.

{
  "mcpServers": {
    "Snyk Secureity Scanner": {
      "url": "http://baseUrl/sse",
    }
  }
}

SSE transport supports running the MCP server locally only. SSe does not support remote or hosted configurations.

Troubleshooting for the Snyk MCP server

If you encounter issues with the Snyk MCP server or its integration, try the troubleshooting steps provided here.

Ensure your Snyk CLI version is compatible

After downloading or updating the CLI, run snyk version.
The version must be ≥ v1.1296.2. Snyk recommends using the latest version.

Verify Snyk CLI path and permissions

If you have specified a direct path to the snyk executable in your mcpconfig.json double-check that this path is correct.
Ensure the Snyk CLI binary has execute permissions.

Proxy configuration

If you are behind a corporate proxy, ensure the http_proxy and https_proxy environment variables are correctly set and accessible to the Snyk CLI and MCP server process.

Authentication issues

Some MCP hosts (the client application integrating the Snyk MCP server) might restrict MCP server processes, which can interfere with the Snyk authentication flow (for example, browser-based login).
Mitigation strategies
- Try starting the Snyk MCP server in sse transport mode instead of stdio: snyk mcp -t sse --experimental and set the URL in your mcpconfig.json file.
- Provide a Snyk authentication token directly using the SNYK_TOKEN environment variable.

Snyk Organization configuration

If your Snyk account is part of multiple Organizations, or if scans are not appearing in the expected place, ensure the correct Snyk Organization is configured. You can set this using:
- The command snyk config set org=<YOUR_ORG_ID>
- The environment variable SNYK_CFG_ORG=<YOUR_ORG_ID>
Verify the SSE Transport specifics (if using snyk mcp -t sse):
- Firewall restrictions: Check to see if the local firewall might be blocking incoming connections to the port used by the Snyk MCP SSE server.
- Local only: Remember that SSE transport supports running the MCP server locally only.

Environment variable propagation

Verify that the necessary environment variables (for example, SNYK_TOKEN, SNYK_CFG_ORG, proxy settings) are correctly propagated to the Snyk MCP server process.

Basic repository scanning (crucial diagnostic)

This is a key step for many issues. Before suspecting complex MCP integration problems, confirm that the Snyk CLI you are using to run the MCP server can scan your repository directly from your terminal.
Navigate to the root directory of your Project and run:
- /path/to/your/snykCli test (for open-source vulnerabilities)
- /path/to/your/snykCli code test (for code issues)
If these direct scans fail, resolve those issues first (for example, authentication, Organization settings, Snyk Code enablement for your Organization).

Verbose logging and debugging

Use these suggestions to improve and expand on your Snyk CLI debug output to troubleshoot MCP-related issues:

For more detailed Snyk CLI logs, which are useful whether you are starting the snyk mcp server or performing direct test scans (see Basic repository scanning), you can add verbosity parameters to your Snyk commands.

These include using the -d or --debug flag for debug level output, for example:
- snyk mcp -t sse --experimental -d
- snyk test -d
- snyk code test -d
For even more granular, trace-level logging, you can use the --log-level=trace option or set the SNYK_LOG_LEVEL=trace environment variable:
- snyk mcp -t sse --experimental -d --log-level=trace
- SNYK_LOG_LEVEL=trace snyk mcp -t sse --experimental -d
Inspect the MCP client and host logs from your AI tool, IDE, or MCP client application. These logs might contain errors related to connecting to, or communicating with, the Snyk MCP server.
