What you unlock
Database management
Create and manage Postgres databases, branches, and roles across your Neon projects.
Branch workflows
Create database branches for development and testing — instant copies of your production data.
SQL execution
Execute SQL queries through your agent — check data, run migrations, or debug issues.
Infrastructure control
Manage compute endpoints, connection URIs, and project settings from chat.
Connect Neon
1
Open Settings → Integrations
In any workspace go to Settings → Integrations and select Neon.
2
Authorize with OAuth
Click Connect and sign in to your Neon account. Grant Mantle the requested permissions to access your projects
and databases.
3
Confirm the connection
Once authorized, you’ll be redirected back to Mantle. The integration status will show as connected.
Agent tools
Add Neon tools to agents that need them. Their access is limited by the connected account and selected tools.Projects

Triggers
Automated triggers for Neon are not yet available. Triggers will be added in a future update — check back soon.
Example use cases
Create a branch for a feature
Create a branch for a feature
Ask your agent to create a Neon branch from production for a new feature — it creates the branch, sets up a compute
endpoint, and returns the connection string ready to use in your development environment.
Quick data lookup
Quick data lookup
Ask “How many users signed up this week?” and the agent executes the SQL query against your database and returns the
result inline — no database client needed.
Schema comparison before merge
Schema comparison before merge
Before merging a feature branch, ask your agent to compare the branch schema against the main branch. It highlights
new tables, modified columns, and missing indexes.
Troubleshooting
OAuth connection failed
OAuth connection failed
Make sure you are signing in with a Neon account that has access to the projects you want to manage. If the
connection fails, try disconnecting and reconnecting from Settings → Integrations → Neon.
Agent can't find my project
Agent can't find my project
Verify the connected Neon account has access to the project. If the project belongs to an organization, ensure your
account has the correct organization membership.
SQL queries time out
SQL queries time out
Neon compute endpoints auto-suspend after inactivity. The first query after suspension may take a moment while the
endpoint wakes up. If timeouts persist, check your endpoint’s auto-suspend configuration.
Branch creation fails
Branch creation fails
Check that your Neon plan allows the number of branches you need. Free tier accounts have branch limits. Verify the
source branch exists and has available capacity.
