FullEnrich MCP server

FullEnrich MCP — B2B contact enrichment for AI agents

FullEnrich finds verified B2B contact data (emails and mobile phone numbers) through waterfall enrichment across 25+ data providers. This repository is the official FullEnrich integration for AI agents: a remote MCP server and a Claude Code plugin with 9 guided skills for prospecting, enrichment, outreach, and recruiting.

Install

Claude Code

Install the plugin to connect the MCP server and add the 9 skills:

/plugin marketplace add FullEnrich/fullenrich-skills
/plugin install fullenrich@fullenrich

Cursor local install

Cursor loads root Agent Plugins from ~/.cursor/plugins/local. Clone this repository directly into the local plugin directory:

mkdir -p ~/.cursor/plugins/local
git clone https://github.com/FullEnrich/fullenrich-skills ~/.cursor/plugins/local/fullenrich

Alternatively, copy the complete repository directly into ~/.cursor/plugins/local/fullenrich.

Restart Cursor or run Developer: Reload Window, then verify that the 9 skills and the fullenrich MCP server appear. The package is not yet listed in the Cursor Marketplace.

FullEnrich is published in the official MCP Registry under io.github.FullEnrich/fullenrich. The public distribution repository linked by the Registry is this repository; the hosted MCP implementation remains private.

Gemini CLI

After this package is released, install the extension from the public repository:

gemini extensions install https://github.com/FullEnrich/fullenrich-skills

Gemini CLI loads the remote MCP server and the 9 skills. Authenticate with FullEnrich on the first MCP connection. The package is not yet listed in the Gemini CLI extension gallery; gallery discovery also requires the gemini-cli-extension GitHub topic.

Antigravity CLI can convert the installed extension, including its skills and MCP configuration, into a native plugin:

agy plugin import gemini

Other Agent Plugins clients

The repository root follows Agent Plugins 1.0. Point a compatible client's local plugin loader at this directory. Installation remains client-specific.

MCP only

Connect the public endpoint from any MCP-compatible client:

https://mcp.fullenrich.com/mcp

On first use, authenticate with your FullEnrich account (OAuth). You need a FullEnrich workspace with credits.

Capability boundary

FullEnrich MCP searches B2B people and companies, enriches contacts, and exports results as CSV or JSON. It has no CRM write tools.

The full-crm skill can orchestrate a separately connected CRM MCP. It checks field mapping and duplicates, then requires explicit confirmation before the separate CRM connector creates or updates records.

Why FullEnrich

• Waterfall enrichment across 25+ providers. Each contact is looked up provider by provider until a verified email or phone number is found. Coverage is higher than any single data source.
• Credits refunded on invalid data. You pay for a verified contact, not a query. If a contact comes back invalid, the credits are refunded.
• Free preview, paid enrichment. Search previews are free (within the MCP preview limit). Exporting search results and enriching contacts cost credits: about 1 credit per email found, 10 per phone found. The skills always state the estimated cost before spending.
• Remote MCP server with OAuth 2.1. No API key to copy around. The server at https://mcp.fullenrich.com/mcp uses the standard OAuth 2.1 flow and works from any MCP client (Claude, Cursor, Windsurf, custom agents).
