Paragon

You run a Paragon MCP Server to connect your Paragon-powered actions and custom tools to client agents via the MCP protocol. This server acts as the bridge between your Paragon actions (like Google Calendar, Salesforce, Slack) and your AI agents, enabling seamless, user-authorized integrations and secure API access.

How to use

You enable your agents to access prebuilt actions from Paragon by pointing them at your MCP server’s SSE endpoint. Your agents can then present available integrations as capabilities, prompt users to authorize through the Connect Portal, and execute actions against connected services. The server handles authentication via Paragon User Tokens and routes requests to the appropriate integration or custom action.

Typical usage pattern with an MCP client looks like this: your client connects to the MCP server’s SSE stream, receives a list of available tools and integrations, and begins a setup flow for any requested integrations. Users complete authorization in the Connect Portal, after which your client can invoke actions, query data, or send notifications through the connected services. If you add custom actions or expose direct API access, those tools appear alongside built-in integrations in the MCP toolset.

How to install

Prerequisites: you need a Paragon account and a development environment with Node.js and npm.

Step by step install flow you should follow:

1. Install Node.js and npm on your machine.

2. Clone the MCP server repository to your workstation.

3. Install dependencies.

npm install

# If you need to run or build locally, follow the project’s start script.
