Paragon MCP Server

Overview

The Paragon MCP Server bridges the gap between conversational AI assistants and real‑world SaaS applications by exposing a rich set of prebuilt actions through the Model Context Protocol (MCP). Instead of building custom connectors for each third‑party service, developers can tap into ActionKit’s catalog of 130+ integrations—ranging from Google Calendar and Salesforce to Slack and beyond—directly from within an AI agent. This eliminates the need for repetitive OAuth flows, reduces development time, and ensures that every action follows a consistent security model.

At its core, the server translates MCP requests into ActionKit calls. When an assistant receives a tool invocation, the server resolves the requested action to an underlying API endpoint, handles authentication via Paragon’s Connect Portal (a secure OAuth 2.0 and API key intake component), and streams the response back to the client. This seamless orchestration allows developers to focus on crafting conversational logic while delegating complex integration plumbing to the MCP layer.

Key capabilities include:

• Dynamic Tool Discovery: The server automatically publishes all available integrations from a developer’s Paragon project as MCP tools, giving agents instant access to actions like creating calendar events or querying CRM records.
• Secure Authorization: Users are prompted through the Connect Portal to grant permissions, ensuring that all data access complies with OAuth best practices and that tokens are stored safely.
• Custom Action Extension: Developers can augment the default catalog with OpenAPI‑defined custom actions or expose raw API endpoints via an experimental proxy tool, enabling highly specialized workflows.
• Fine‑Grained Limiting: Environment variables allow selective exposure of integrations or tools, making it easy to tailor the agent’s capabilities to specific roles or compliance requirements.

Real‑world scenarios abound: a customer support bot can schedule follow‑up calls in Google Calendar, pull ticket details from Salesforce, and post updates to Slack—all within a single conversation. A sales assistant can query product inventories, create quotes, and send proposals to prospects without leaving the chat interface. By consolidating these operations under a single MCP server, teams gain consistent logging, monitoring, and audit trails across all integrations.

Integrating the Paragon MCP Server into AI workflows is straightforward. Once the server is running, a client—such as Cursor or any MCP‑compatible assistant—simply registers the server URL. The agent then receives a catalog of tools that can be invoked with natural language prompts, and the server handles every downstream call transparently. This plug‑and‑play model not only accelerates development but also ensures that future integrations can be added to ActionKit and automatically become available to the agent, keeping the system future‑proof and scalable.
