How to integrate Candid MCP with Atomic Agent

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 Candid.

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 Candid account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Candid

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

The Candid MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Candid account. It provides structured and secure access to Candid’s nonprofit, grantmaker, and social-sector knowledge, so your agent can search organizations, resolve organization mentions, identify locations, classify topics, and answer sector questions on your behalf.

• Nonprofit and grantmaker research: Have your agent find organizations by name, mission, EIN, location, or type of work.
• Organization name resolution: Let the agent identify organizations mentioned in text and connect them to official Candid nonprofit profiles.
• Geographic identification: Direct your agent to detect and match named places found in reports, proposals, or other supplied text.
• Philanthropy topic classification: Instruct your agent to align text with relevant terms from Candid’s Philanthropy Classification System.
• Social-sector knowledge: Have your agent answer questions about philanthropy and the social sector using guidance from Candid’s subject matter experts, with the current date available for time-sensitive requests.

Use Candid from Atomic Agent

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