In short
MCP connectors let Granular agents work with outside tools and services — like Notion, Google Drive, and more — so they can act across your stack.

What is MCP?
MCP (Model Context Protocol) is how Granular agents connect to outside tools and services. A connector gives your agent the ability to read and act in another app — so work isn't limited to your local files.
Connecting a tool
Granular supports multi-account connectors with OAuth and verified presets, so connecting a service is a guided, click-through step. Once connected, your agent can use that tool as part of getting work done.
Keys stay in the Vault
Any tokens a connector needs live in the encrypted Vault, not in plain files — so connecting tools never means scattering secrets around.
Frequently asked questions
What can I connect?
A growing set of services via MCP, including verified presets like Notion, with more connectors over time.
