Neon MCP integration

Add auth oauth provider

Adds an OAuth provider configuration to the specified branch's Neon Auth integration. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.

Add auth trusted domain

Adds a domain to the redirect URI whitelist for the specified branch. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.

Compare database schema

Compare one database's SQL schema on a branch to another. `database_name` is required. Omit `base_branch_id` to compare against the parent; it is a branch id (`br-...`), not a name. Pass `lsn`, `timestamp`, `base_lsn`, or `base_timestamp` only for a point-in-time comparison. branch_id is a branch i…

Complete database migration

Apply or discard a prepared migration and delete the temporary branch. NEVER run autonomously; always ask the user first. Pass migration_id, migration_sql, database_name, project_id, temporary_branch_id, and parent_branch_id from prepare_database_migration. Set apply_changes false to discard; omitt…

Complete query tuning

Apply or discard query-tuning changes and delete the temporary branch. NEVER run autonomously. Before calling, apply suggested SQL with run_sql on the temporary branch and re-run explain_sql_statement. Pass the tuning_id from prepare_query_tuning, not the branch id, plus temporary_branch_id. Set ap…

Create auth user

Creates a new user in the Neon Auth user directory for the specified branch. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.

Create branch

Creates a branch with a read-write compute and waits until it is ready. Pass `no_compute: true` to skip the endpoint. Does not return a connection string; call `get_connection_string` with the project and branch id. Copies the parent at HEAD; point-in-time restore is `restore_snapshot`.

Create postgres database

Creates a database in the specified branch. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.

Create postgres endpoint

Creates a compute endpoint on a branch. Does not return a connection string; call `get_connection_string`.

Create postgres role

Creates a Postgres role in the specified branch. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.

Create project

Creates a Neon project and waits until the default compute is ready. Pass `org_id` with a personal API key. Does not return a connection string; call `get_connection_string` with the project id.

Create snapshot

Creates a snapshot from the specified branch. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.
