ServiceGraph

ServiceGraph is a structured B2B firm directory designed specifically for AI agents, offering a comprehensive catalog of over 100,000 US professional-services firms across 22 industries including law, marketing, consulting, accounting, IT, architecture, engineering, HR, PR, and design. The platform serves as a foundational data layer for procurement, sales prospecting, and CRM enrichment use cases, with meticulously structured firm data including industry classification, service taxonomy, contact information, review aggregation, and engagement metrics. Unlike traditional search engines, ServiceGraph provides queryable filters for industry categories, service tags, geography, company size, and third-party ratings, enabling AI agents to generate precise vendor shortlists without web scraping. The system operates as an MCP (Model Context Protocol) server skill that integrates with popular AI coding assistants and can be accessed via direct API calls, featuring a free tier with generous monthly quotas for exploration and production use.
