Overview

AI-generated overview

Lets an assistant look up public records and domain-graph data for US-eligible businesses through a remote enrichment endpoint.

What it does
Firmograph is a remote MCP server that provides public-record and domain-graph lookup for business entities. Its described capability is an enrichment call (POST /v1/enrich) that returns firmographic detail for US-eligible companies. It is explicitly not a universal SMB database, so coverage is limited rather than comprehensive.
When to use it
Useful when an assistant needs to enrich or verify US business records and domain relationships, for example in sales, research, or data-cleaning workflows. It is not intended for global or non-US company coverage.
Requirements
A remote MCP client connecting to the hosted endpoint over streamable HTTP. The description mentions an x402 POST /v1/enrich call, which implies payment-related access; no accounts, API keys, environment variables, or headers are declared.
Before you install
The description references x402, a payment protocol, so enrichment calls may cost money; confirm pricing and limits before use. Queries send business identifiers to a third-party hosted service. No authentication is declared, so do not send confidential data.
