Supabase Read MCP

Let your phone agent look up live project data in Supabase, read-only, while the caller waits.

Supabase Read MCP lets your AgentCalls agent inspect the Supabase projects you authorize, including databases, schemas, logs, branches, Edge Functions and storage settings. Access is read-only, so the agent can check information but cannot change your data. Connect it once from your AgentCalls dashboard with your own Supabase credentials, and the agent can answer status and data questions during a live call.

Example calls

Inbound status check from a client

Caller
Hi, my customer portal has been slow since this morning. Is anything wrong with your backend?
Agent
I can check that now. Can I have the name of the project or the account email you signed up with?
Caller
It's Northside Clinic, the account is ops@northsideclinic.co.uk.
Agent
Thanks. The database is healthy and the Edge Function ran without errors at 9:12. Recent logs show a spike in requests around 8:50, which matches what you saw. I've added a note to your ticket so the team can follow up.

Lookup during a support call

Caller
Did the nightly export from our storage bucket finish last night?
Agent
Let me check the logs for that project. One moment.
Agent
Yes, the export ran at 2:00 AM and finished at 2:04 AM. The storage configuration for that bucket is unchanged. Would you like me to read you the file count?
Caller
No, that's all I needed. Thanks, Sara.

Outbound follow-up on a deployment

Agent
Hello, this is calling from Riyadh Dental Group about the branch deployment you requested on Tuesday. Is now a good time?
Caller
Yes, go ahead.
Agent
The new branch is live and its database schema matches the production layout. Two Edge Functions are still listed as pending. Do you want me to leave a message for your developer to finish them?
Caller
Yes, please. Send it to Omar.
