Can an AI agent sign up for Nutshell on its own?

No. Sign-up: blocked. A bot check from The product's own check stopped our agent there. The page names a VPN; the same address was not tried from another origin.

Does Nutshell have an MCP server, and can an agent connect to it?

Yes. Nutshell has an official MCP server. The server is hosted and signs an agent in with OAuth. A new agent can't get in on its own: in the drive of 28 Oct 2026, our agent stopped at sign up (it was blocked).

Tips for agent builders

From this drive

3 tips

Read the docs as markdown: append .md to any developers.nutshell.com page or send Accept: text/markdown.
The REST API takes HTTP Basic with the user's email as username and an API key (Setup > API keys) as password, at https://app.nutshell.com/rest.
The MCP server is https://app.nutshell.com/mcp (OAuth with DCR, scopes read and write); it creates and updates records but cannot delete them.
