How to integrate OSV MCP with Atomic Agent

Connect Atomic Agent to OSV MCP. List all vulnerabilities for package django, get vulnerability details for cve-2023-1234, and more using natural language, with authentication handled for you.

OSV is an open vulnerability database and API for querying vulnerabilities by package, version, commit, or vulnerability identifier. It helps you quickly find and track known software vulnerabilities across ecosystems.

Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including OSV.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a OSV account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to OSV

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect OSV to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in OSV. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your OSV account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

What is the OSV MCP server, and what's possible with it?

The OSV MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OSV account. It provides structured and secure access so your agent can perform OSV operations on your behalf.

Use OSV from Atomic Agent

With your account connected, ask Atomic Agent to work with OSV in natural language. You can connect more apps through the same Composio integration as you need them.

Visit the Atomic Agent website or inspect the Atomic Agent source code.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

TOOLS

Supported Tools

Every OSV action and event your agent gets out of the box.

Determine Version

Experimentally rank probable versions of an OSS-Fuzz C/C++ library from relative source-file paths and base64-encoded MD5 hashes.

Get Import Findings

Experimentally list OSV records from one exact import source that failed import-time quality checks; intended for OSV source maintainers and may return no records.

Get Vulnerability

Return the complete OSV record for one case-sensitive vulnerability ID, including affected versions, ranges, severity, references, and aliases.

Query Vulnerabilities

Find full OSV vulnerability records affecting one package, package version, package URL, or commit.

Query Vulnerabilities Batch

Check up to 1,000 packages, package versions, package URLs, or commits in one request and return position-matched compact vulnerability IDs.

FAQ

Frequently asked questions

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

Yes, you can. Atomic Agent 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 OSV tools.

Yes, absolutely. You can configure which OSV 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 OSV data and credentials are handled as safely as possible.
