MCP Server Overview

The Versium REACH MCP server lets you query Versium REACH APIs using natural language from an MCP-compatible agent. Instead of manually constructing API requests, you can ask questions in plain English (for example, “Enrich these contacts” or “Estimate the available audience size for this market segment”), and the agent will call the appropriate REACH API operations on your behalf.

What You Need

An active Versium REACH subscription
API access enabled for your account (most subscription users should have this by default)
An MCP-compatible client (see setup guides below)

Get Started

Setup with Claude
Setup with ChatGPT (Coming soon!)
Other Agents with MCP Support
- For other agents with MCP support, follow the documentation provided by the agent platform. When asked for the MCP URL, use https://app.versium.com/mcp/reach
- The agent must support the Streamable HTTP transport method and OAuth dynamic client registration.

We will add documentation for additional popular agents as support becomes available. Not all agents support MCP yet as it is a relatively new protocol established for streamlining agent communication with external platforms. You can read more at https://modelcontextprotocol.io/

Tips & Tricks

After adding the connection, you can ask the agent questions like “What can you do with your connection to Versium REACH?” or “How can we use the Versium REACH tools?” and it can reply using information from the tools it sees.
