neon connection-string [branch]

Tool: get_connection_string

Get a PostgreSQL connection string for a Neon database. All parameters are optional; the tool resolves the project, branch, and database automatically if not specified. Requires write access: the connection string carries a privileged role password, so it is unavailable in read-only mode. A read-only caller who needs a DATABASE_URL must copy it from https://console.neon.tech manually.

projectId (string, required) The ID of the project. If not provided, the only available project will be used.
branchId (string, optional) The ID or name of the branch. If not provided, the default branch will be used.
computeId (string, optional) The ID of the compute/endpoint. If not provided, the read-write compute associated with the branch will be used.
databaseName (string, optional)
roleName (string, optional) The name of the role to connect with. If not provided, the database owner name will be used.

The endpoint ID. Defaults to the read-write endpoint_id associated with the branch_id if not specified.

string

The database name

Errors

default

General error

This endpoint can return the standard Neon API error response.

Response fields

message Required. Human-readable error message.
code Required. Machine-readable error code.
request_id Optional. Request identifier for debugging. You can provide one with the X-Request-ID header.

Retry guidance

If no response is returned, the request may still have reached the server. This is why retry safety depends on the method and status code.

Idempotent methods (GET, HEAD, OPTIONS) are generally safe to retry after a network error or timeout. Non-idempotent methods (POST, PATCH, DELETE, PUT) can change state, so avoid automatic retries unless your workflow can tolerate duplicate effects.

Responses with 423 Locked or 503 Service Unavailable are safe to retry. 423 Locked means the resource is temporarily locked, usually because another operation is in progress.
