Neon
Connect Neon so Mogplex agents can manage Postgres projects and branches and run SQL.
Connect Neon to let agents create database branches for a change, inspect schemas, run SQL, and prepare migrations.
| Type | Remote MCP server, https://mcp.neon.tech/mcp |
| Credential | Neon API key |
| Where tools load | Every surface that loads connection tools |
Connect
- In Neon, create an API key under Account settings → API keys. The preset's Get a token link opens this page.
- In Mogplex, open Connections → Integrations.
- Under Quick Add — MCP Presets, select + Add on Neon.
- Paste the key, then select Add.
- Test the saved connection and confirm that it lists tools.
A Neon API key can manage and delete projects the account owns. Prefer an organization key with limited reach, scope the connection to the repos that need it, and consider Ask before running tools.
Use it
- "Create a Neon branch from
main, apply the migration in this PR to it, and report any errors." - "Explain why this query on the
eventstable is slow and suggest an index."
Troubleshooting
| Symptom | Check |
|---|---|
| Test fails with an auth error | The key was revoked. Create a new key and update the connection. |
| Agent cannot see a project | The key belongs to a different account or organization. |
