Snyk is a developer security platform for finding issues in code, dependencies, containers, and cloud infrastructure. It helps teams prioritize vulnerabilities and fix them before they reach production.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Snyk account to Claude via Composio Connect, enabling it to list open vulnerabilities in your Snyk projects, prioritize critical Snyk issues by project, review Snyk dependency risks across repositories, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Snyk account

Back in Claude, ask it to connect to Snyk or give it any Snyk-related task.

For example, ask Claude to:

  • "List open vulnerabilities in your Snyk projects"
  • "Prioritize critical Snyk issues by project"
  • "Review Snyk dependency risks across repositories"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Snyk account is ready to use.

What is the Snyk Claude Connector, and what's possible with it?

The Snyk MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Snyk account. It provides structured and secure access to your projects, security findings, container images, SBOM tests, collections, and organization settings, so your agent can review vulnerabilities, inspect projects and images, analyze software bills of materials, organize projects, and update security settings on your behalf.

  • Security issue investigation: Have your agent retrieve organization issues, inspect individual findings, review data flows for Snyk Code issues, and list unsuppressed component findings from completed package tests.
  • Project and container management: Let the agent find project details, list container images, inspect a specific image, update project attributes, or remove projects and targets when needed.
  • SBOM analysis: Direct your agent to start vulnerability analysis for a CycloneDX or SPDX SBOM, check the test status, review affected packages, and download a project SBOM.
  • Project organization: Instruct your agent to create and manage collections, add projects to collections, list collection projects, and review project and issue counts.
  • Organization security settings: Have your agent review Snyk Code and Infrastructure as Code settings, inspect Open Source Broker and private registry settings, manage ignore policies, and check Broker connections.

Troubleshooting

1. Why does Claude not use the Composio connector for Snyk?

The connector can show as connected, but Claude must use it in each Snyk conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Snyk again.

2. Why does Claude show an MCP server error before Snyk connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Snyk.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Snyk.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Snyk authorization link not work?

The Composio connector is one server. Your Snyk account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Snyk connection.
  • Composio creates a fresh Snyk authorization link.
  • Open that link in your browser and finish the Snyk sign-in.

4. Why do Snyk actions fail after they worked before?

The Snyk connection can expire or lose permission.

  • Ask Claude to inspect the Snyk connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Snyk account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Snyk.
  • If the action still fails with a permission error, check that the connected account has that permission in Snyk itself.

5. How do I switch to a different Snyk account?

Claude can manage the Snyk connection for you.

  • Ask Claude to disconnect or delete the current Snyk account.
  • Ask Claude to connect Snyk again.
  • Open the new Composio authorization link for Snyk.
  • Sign in with the other Snyk account in the browser.
  • After the account connects, ask Claude to retry the Snyk task.

6. Why is my Snyk connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Snyk connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Snyk tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Snyk.

FAQ

Frequently asked questions

With a standalone Snyk MCP server, the agents and LLMs can only access a fixed set of Snyk tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Snyk and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Snyk tools.

Yes, absolutely. You can configure which Snyk scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Snyk data and credentials are handled as safely as possible.
