| enrich-company | Look up a company's full profile — firmographics, financials, corporate structure, growth signals |
| enrich-contact | Look up a person's professional profile — title, department, contact details, accuracy score |
| recommend-contacts | Get AI-powered contact recommendations at a target company based on your ZoomInfo interaction history |

The plugin registers ZoomInfo's hosted MCP server (https://mcp.zoominfo.com/mcp) and exposes the skills above as natural-language workflows. Each skill orchestrates multiple ZoomInfo API calls — lookups, searches, enrichment, similarity — and formats the results into actionable output.
No API keys are configured in this repo. Authentication is handled through your ZoomInfo session.
