# Create a Shared Database Table

## Action
Create a structured table in [[entity-supabase-d21]] and connect it to your agent via [[entity-mcp-d21]].

## Steps
1. In your Supabase instance, **create a new table** dedicated to a specific domain (e.g., household maintenance, job hunting, networking).
2. Add columns for the **specific data points** you want to track in that domain.
3. **Verify MCP access**: ensure your MCP server is configured so your AI agent can read from and write to this new table — i.e., the [[concept-agent-door]] is open.

## Outcome
A single source of truth accessible by both your AI agent and your future visual dashboard. This table is now a live [[concept-shared-surface]].

## Next Steps
Follow [[action-generate-ui-code]] and [[action-deploy-vercel]] to build the [[concept-human-door]] for this same table.

## Container Framework
This is step 1 of [[framework-open-brain-build]].
