Official ZoomInfo repository packages the hosted MCP registration, client plugin metadata, and skills. The hosted server implementation is not in this repository, so its stars are distribution evidence rather than server-implementation adoption.
ZoomInfo's current MCP server is hosted; its repository distributes plugin/configuration metadata and no exact server package is published.

Evidence-backed setup
Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.
Transport not recorded
Complete client-specific setup, verification and removal are not documented in this reviewed source.
Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

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.
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:
{
"mcpServers": {
"zoominfo": {
"type": "http",
"url": "https://mcp.zoominfo.com/mcp"
}
}
}
This repository includes metadata for multiple plugin-capable client environments:
| Path | Purpose |
|---|---|
.mcp.json | MCP server registration (all clients) |
.codex-plugin/plugin.json | Codex/OpenAI plugin metadata |
.claude-plugin/plugin.json | Claude plugin metadata |
.claude-plugin/marketplace.json | Claude marketplace metadata |
.cursor-plugin/plugin.json | Cursor plugin metadata |
.cursor-plugin/marketplace.json | Cursor marketplace metadata |
skills/ | Task-specific workflows usable by clients that support skills |
Install or register the plugin according to your client's plugin or MCP workflow. For local development, clone this repository and point your client at the repo root or relevant manifest path.
git clone https://github.com/Zoominfo/zoominfo-mcp-plugin.git
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.
