Overview

AI-generated overview

Lets an assistant search and enrich ZoomInfo company, contact, and buyer-intent data for sales and marketing research.

What you can do
Connects to ZoomInfo's hosted MCP server to find companies, contacts, and buying committee members, and to enrich account, lead, and contact records with business information. It supports building targeted lists, finding similar companies or contacts, and researching accounts, competitors, markets, intent signals, and technology stacks. The accompanying plugin adds task-focused skills such as account research, meeting prep, lead and account scoring, TAM sizing, and outreach personalization.
When to use it
Use it when an assistant needs go-to-market intelligence for sales, marketing, or revenue work: preparing for calls, prioritizing inbound leads, building account or contact lists, or sizing a market or territory.
Requirements
A remote MCP client that supports HTTP connections and OAuth. A ZoomInfo account with the appropriate API access and product entitlements is required; authentication is completed through the OAuth flow, and the client sends an Authorization bearer token.
Before you install
Access is tied to your ZoomInfo account and entitlements, and queries send search and enrichment criteria to ZoomInfo's hosted service. Review what account, contact, and intent data your client may expose before connecting.

Installation

In SourceWeft

  1. Open ZoomInfo in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Zoominfo%2Fzoominfo-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

ZoomInfo MCP Plugin

Use ZoomInfo go-to-market intelligence from LLM clients that support MCP servers, plugin manifests, and/or skills.

This repo packages ZoomInfo's hosted MCP server with client-specific plugin metadata and task-focused skills for sales, marketing, and revenue workflows. It is intended to work across supported LLM clients rather than being tied to a single provider.

What It Enables

  • Find companies, contacts, and buying committee members
  • Enrich account, lead, and contact records with business information
  • Build targeted account and contact lists
  • Identify similar companies, similar contacts, and recommended contacts
  • Research accounts, competitors, markets, intent signals, and technology stacks
  • Prepare for sales calls, prioritize inbound leads, and personalize outreach
  • Size TAM and refine ICP or territory filters

Try Asking

  • "Help me prepare for a meeting with Apple's VP of Marketing this afternoon."
  • "Build me a list of SaaS companies in the UK with 200-500 employees using Salesforce."
  • "Find companies showing high buyer intent on data observability in the last 30 days."

Prerequisites

  • An LLM client or agent environment that supports MCP and/or local plugin manifests
  • A ZoomInfo account with the appropriate API access and product entitlements

MCP Server

The plugin registers ZoomInfo's hosted MCP server (https://mcp.zoominfo.com/mcp). Authentication is handled through your ZoomInfo account via OAuth — no API keys are stored in this repo. Clients connect over HTTP and complete the OAuth flow natively. All clients share the registration defined in .mcp.json:

json
{  "mcpServers": {    "zoominfo": {      "type": "http",      "url": "https://mcp.zoominfo.com/mcp"    }  }}

Client Support

This repository includes metadata for multiple plugin-capable client environments:

Skills

Skills are task-focused playbooks the agent follows to return structured outputs (briefs, tables, scores, emails) instead of raw tool JSON. Trigger them with /skill-name or plain language ("prep me for a meeting with Acme"); the agent can also select the right skill automatically when your request matches.
