Connect an AI assistant to the UltraCart docs
UltraCart runs a documentation server for the Model Context Protocol (MCP), an open standard that lets AI apps use outside tools. Add it to an AI app and the app can search and read the UltraCart merchant guides, developer guides and REST API reference, plus the rules for building against the API. That way you get answers drawn from the current docs instead of the app's memory.
The server is free, read-only, and needs no API key.

Set it up in your AI app
Step-by-step setup for Claude (desktop app and claude.ai), Claude Code, ChatGPT, Codex, Cursor, VS Code, Gemini and many other apps is on the UltraCart docs MCP server page. Pick your app there for a one-click link or the exact command to copy.
What the server provides
The server gives your AI app five tools. They all read documentation.
| Tool | What it does |
|---|---|
search_docs | Searches merchant guides, developer guides and the API reference, or just one of them. |
get_page | Reads any docs page in full. |
find_api_operation | Finds the REST API call for a task, a request line or an operation id. |
get_api_operation | Reads one API call: parameters, fields, errors, SDK setup and code samples in your language. |
get_ground_rules | Returns the rules for building against the API: rate limits, versions, expansion, paging and testing. |
What it does not do
The server only reads the public documentation. It does not read or change your store data, and it has no access to your orders, customers or account.
- To work with account data from code, use the REST API and SDKs.
- To run BigQuery reports from Claude Code, see AI Reporting with Claude Code.
Not the same as the AI Agents MCP servers setting
The CRM MCP servers setting works in the opposite direction. It lets an UltraCart AI Agent connect out to a tool server that someone else runs. The docs server described here is one you connect your own AI app to.
