Integrations

Connect a platform in your workspace and Penumbra syncs it, auto-models it as a graph, and reconciles your platforms into one connected brain you build on with the SDK and MCP.

Penumbra connects to the tools your work lives in. You connect a platform in your Penumbra workspace, and Penumbra syncs it, auto-models it as a graph (no hand-built shape), and reconciles across platforms — the meeting in Granola resolves to its Google Calendar event, the people and companies to their Attio records — so your tools become one brain you can query and build on.

Most platforms connect in your Penumbra workspace (the web app) through OAuth. Token-paste platforms (Granola, Attio) can also connect headlessly over REST with /v1/connections. Set one up in the workspace, or see the API reference.

How it works

1. Connect, in your workspace

   Authenticate into the platform or add an API key, from your Penumbra workspace.

2. Sync and auto-model

   Penumbra pulls the platform and models it as a graph — its native types and relationships — with no manual shaping. The raw records land on the mirror plane.

3. Reconcile

   Penumbra connects the entities that recur across platforms, weaving your separate platform graphs into one.

Live platforms

Four platforms are auto-mapped today:

Platform	What it graphs
Linear	Issues and projects
Attio	CRM records — companies, people, deals
Google Calendar	Events and meetings
Granola	Meeting notes and transcripts

Coming next: Slack and Gmail. To enable a platform for your project, email [e-mail].

Build on it

Once a platform is synced, the graph is yours to use:

• Query and traverse it with the SDK or an agent over MCP.
• Check what is fit to act on with decision quality.
• Compose it into a team or company brain.

Bootstrap a shape from the web

Separate from platform sync, and available via the API: point Penumbra at a URL and it crawls the site and proposes a shape from it. See Firecrawl.

Bring your own

Anything that produces structured data can feed Penumbra: extract it elsewhere, then capture it into the graph with pb.capture or pb.extract. Want a platform we have not connected yet? Tell us at [e-mail].
