Growth Engineer

growth.engineer

Go-to-market tools and workflows, written as files any agent can run.

An open-source catalog of go-to-market companies, the functions an agent can call on each one, and workflows that chain those functions into a result. Every entry is a markdown file in this repository.

What is this?

Handing a go-to-market tool to an agent means digging through docs written for people: which key to create, which endpoint to call, whether there is an MCP server, what a call costs. And a growth play that works usually lives in someone's notes, where no agent can run it.

growth.engineer writes both down as markdown files an agent can follow:

Entry	Example key	What the file holds
Company	apollo	Who the company is and how an agent reaches it: MCP server, CLI or API, and the credential each one needs.
Tool	apollo/enrich-person	One function an agent can call: the exact MCP tool, CLI command or API endpoint, and the docs page that names it.
Workflow	funding-signal-outbound	Up to ten steps across tools that reach a result: the one motion it serves, the outcome the user gets, the inputs to ask for, how to set up each tool, and the steps.

Paste a workflow file into Claude, ChatGPT, Cursor or any other agent and it can run the play. The file tells the agent to ask before it sends a message, spends money or changes data.

Facts come from each vendor's own documentation, and every tool links the page that documents its call.

Connect your agent

The site runs an MCP server at https://www.growth.engineer/mcp (Streamable HTTP, no sign-in). Its search tool finds workflows, tools and companies, and get returns a file; neither changes anything. A third tool, submit_feedback, sends a bug report, request or question to the maintainers. Every workflow is also an MCP prompt that takes the workflow's inputs as arguments, and three more prompts (contribute-workflow, contribute-tool, contribute-company) walk an agent through adding to the catalog.
