How Atomic Agent connects to MoltSets

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 MoltSets 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 MoltSets. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your MoltSets 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.

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

The MoltSets MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your MoltSets account. It provides structured and secure access to people and company search, profile enrichment, contact discovery, advertising identity resolution, and account usage data, so your agent can find prospects, enrich professional profiles, discover validated contact details, resolve company visitors, and review account usage on your behalf.

  • People and company discovery: Have your agent search for ranked people and companies using names, domains, firmographics, industries, locations, and inclusion or exclusion filters.
  • Professional profile enrichment: Let the agent enrich LinkedIn profiles or find business profiles from a person’s name and company, including company details and experience when available.
  • Contact detail discovery: Direct your agent to find validated business or personal email addresses, mobile phone data, LinkedIn profiles, or reverse-match a person and company profile from an email address.
  • Advertising identity resolution: Instruct your agent to retrieve email hashes, match a business email to a hashed personal email, or resolve an email address to a mobile advertising ID for audience matching.
  • Account and usage reporting: Have your agent review plan capabilities, token and phone-token balances, billing details, tool costs, and daily or aggregate API usage.

Use MoltSets from Atomic Agent

With your account connected, ask Atomic Agent to work with MoltSets 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.

FAQ

Frequently asked questions

With a standalone MoltSets MCP server, the agents and LLMs can only access a fixed set of MoltSets tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from MoltSets 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 MoltSets tools.

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