Overview

AI-generated overview

Firmograph is a remote MCP server that lets an assistant look up company information by domain from public records and a domain graph.

What you can do
Enrich a company from a domain name, returning public-record and domain-graph company data through a single enrich tool. Responses include a coverage block, and unknown domains return an explicit 404 rather than partial data. The tool is paid per call through x402 v2 with an upto scheme in USDC on Base.
When to use it
Use it when an assistant needs company details keyed by a web domain, such as firmographic lookups during research or lead qualification, and you are prepared to pay per call.
Requirements
A remote MCP connection to the Firmograph endpoint over streamable HTTP. No account, API key, environment variable or header is declared. A crypto payment setup for x402 v2 in USDC on Base is needed for the paid enrich tool.
Before you install
The enrich tool is paid: each call requires an x402 v2 payment in USDC on Base, up to the stated maximum in atomic units. Without a settled payment the call fails with a PaymentRequired error, and settlement over MCP is not enabled in this version, so payment handling may need to happen outside the MCP connection. Domains you submit are sent to a third-party service.

Installation

In SourceWeft

  1. Open Firmograph in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.apigrid-ch%2Ffirmograph/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
