Claude and ChatGPT plug into Heyno, and Heyno connects the rest
One MCP server that exposes your whole working context to any model you already use.
The Model Context Protocol standardizes how models reach tools. Heyno ships an MCP server, which means the assistant you already use can work through your Heyno context instead of being wired to every app separately.
The N-by-M problem
Connecting M models to N systems directly is M×N pieces of integration, each with its own auth, its own permissions, and its own failure mode. Routing through one server that already holds the connections makes it M+N.
That is the entire architectural argument, and it is why the protocol exists.
What the server exposes
Tools for your files, mail, calendar, contacts, tasks, memory, and business records: the same surface the assistant uses internally, with the same guardrails.
Read tools return cited content. Write tools are gated by the same approval policy that applies inside the product.
Permissions travel with the tool
A model calling through MCP inherits the permissions of the person who authorized the connection. It cannot read what they could not read, and it cannot perform an action they could not perform.
Why route through Heyno
Because the context is already assembled. A model that reaches your drive directly sees files; a model that reaches them through Heyno sees files plus what was agreed about them.
Getting started
The server, the tool list, and the auth flow are documented in the MCP reference.
