`POST /projects` Creates a Neon project within an organization. If using a personal API key, include the `org_id` parameter to specify which organization to create the project in. If using an org API key, `org_id` is automatically inferred from the key. Plan limits define how many projects you can create. For more information, see [Manage projects](/guides/manage-operate-manage-projects). You can specify a region and Postgres version in the request body. Neon supports Postgres 14 through 18, with 19 rolling out to enabled regions. For supported regions and `region_id` values, see [Regions](/guides/manage-operate-introduction-regions). ## Request body - `project` (object, required) Configuration for the new project, including name, region, and Postgres compute and storage settings. - `settings` (object, optional) Project-level settings applied at creation. - `quota` (object, optional) Per-project consumption quotas. If a quota is exceeded, all active computes are automatically suspended and cannot be started via API calls or incoming connections. The exception is `logical_size_bytes`, which is enforced per branch. If a branch exceeds its `logical_size_bytes` quota, computes can still be started, but write operations will fail—allowing data to be deleted to free up space. Computes on other branches are not affected. Setting `logical_size_bytes` overrides any lower value set by the `neon.max_cluster_size` Postgres setting. Quotas are enforced using per-project consumption metrics with the same names. These metrics reset at the start of each billing period. `logical_size_bytes` is also an exception—it reflects the total data stored in a branch and does not reset. A zero or empty quota value means “unlimited.” - `active_time_seconds` (integer, optional, format: int64) The total amount of wall-clock time allowed to be spent by the project's compute endpoints. - `compute_time_seconds` (integer, optional, format: int64) The total amount of CPU seconds allowed to be spent by the project's compute endpoints. - `written_data_bytes` (integer, optional, format: int64) Total amount of data written to all of a project's branches. - `data_transfer_bytes` (integer, optional, format: int64) Total amount of data transferred from all of a project's branches using the proxy. - `logical_size_bytes` (integer, optional, format: int64) Limit on the logical size of every project's branch. If a branch exceeds its `logical_size_bytes` quota, computes can still be started, but write operations will fail—allowing data to be deleted to free up space. Computes on other branches are not affected. Setting `logical_size_bytes` overrides any lower value set by the `neon.max_cluster_size` Postgres setting. - `allowed_ips` (object, optional) A list of IP addresses that are allowed to connect to the compute endpoint. If the list is empty or not set, all IP addresses are allowed. If protected\_branches\_only is true, the list will be applied only to protected branches. - `ips` (array, optional) A list of IP addresses that are allowed to connect to the endpoint. - `protected_branches_only` (boolean, optional) If true, the list will be applied only to protected branches. - `enable_logical_replication` (boolean, optional) Sets wal\_level=logical for all compute endpoints in this project. All active endpoints will be suspended. Once enabled, logical replication cannot be disabled. - `maintenance_window` (object, optional) A maintenance window is a time period during which Neon may perform maintenance on the project's infrastructure. During this time, the project's compute endpoints may be unavailable and existing connections can be interrupted. - `weekdays` (array, required) A list of weekdays when the maintenance window is active. Encoded as ints, where 1 - Monday, and 7 - Sunday. - `start_time` (string, required) Start time of the maintenance window, in the format of "HH\:MM". Uses UTC. - `end_time` (string, required) End time of the maintenance window, in the format of "HH\:MM". Uses UTC. - `block_public_connections` (boolean, optional) When set, connections from the public internet are disallowed. This supersedes the AllowedIPs list. This parameter is under active development and its semantics may change in the future. - `block_vpc_connections` (boolean, optional) When set, connections using VPC endpoints are disallowed. This parameter is under active development and its semantics may change in the future. - `audit_log_level` (string, optional) Audit logging level, set only on HIPAA-enabled organizations (absent otherwise). Values: `base`, `extended`, `full`; HIPAA defaults to `extended`. Cannot be lowered back to `base` once `extended` or `full`. Possible values: `base`, `extended`, `full` - `hipaa` (boolean, optional) Enables HIPAA compliance mode for the project, including audit logging. - `preload_libraries` (object, optional) The shared libraries to preload into the project's compute instances. - `use_defaults` (boolean, optional) When true, the project's preload libraries include the platform default set in addition to any libraries listed in `enabled_libraries`. - `enabled_libraries` (array, optional) Names of shared preload libraries to enable for the project. - `name` (string, optional) The project name. If not specified, the name will be identical to the generated project ID - `branch` (object, optional) Configuration for the initial branch created with the project. - `name` (string, optional) The default branch name. If not specified, the default branch name, `main`, will be used. - `role_name` (string, optional) The role name. If not specified, the default role name, `{database_name}_owner`, will be used. - `database_name` (string, optional) The database name. If not specified, the default database name, `neondb`, will be used. - `annotations` (object, optional) Arbitrary key-value metadata to attach to the branch. - `autoscaling_limit_min_cu` (number, optional, deprecated) Deprecated. Use `default_endpoint_settings.autoscaling_limit_min_cu` instead. The minimum number of Compute Units. The minimum value is `0.25`. See [Compute size and Autoscaling configuration](/guides/manage-operate-manage-computes#compute-size-and-autoscaling-configuration) for more information. - `autoscaling_limit_max_cu` (number, optional, deprecated) Deprecated. Use `default_endpoint_settings.autoscaling_limit_max_cu` instead. The maximum number of Compute Units. See [Compute size and Autoscaling configuration](/guides/manage-operate-manage-computes#compute-size-and-autoscaling-configuration) for more information. - `provisioner` (string, optional) Compute provisioner. `k8s-neonvm` (default) supports Autoscaling; `k8s-pod` is fixed-size compute. Also `docker` and `serverless-platform`. - `region_id` (string, optional) The region identifier. Refer to our [Regions](/guides/manage-operate-introduction-regions) documentation for supported regions. Values are specified in this format: `aws-us-east-1` - `default_endpoint_settings` (object, optional) A collection of settings for a Neon endpoint - `pg_settings` (object, optional) A raw representation of Postgres settings - `pgbouncer_settings` (object, optional, deprecated) Deprecated. Use the endpoint-level connection pooler configuration instead. Removal scheduled for June 20, 2026. - `autoscaling_limit_min_cu` (number, optional) Minimum number of Compute Units for this endpoint. At least 0.25 and no greater than `autoscaling_limit_max_cu`. - `autoscaling_limit_max_cu` (number, optional) Default maximum number of Compute Units for endpoints created under this account.

Minimum is plan-dependent (Scale: 60); maximum 604800 (one week). Free cannot change it; Launch can only enable or disable; Scale can set any value. - `pg_version` (integer, optional) The major Postgres version number. Supported versions are `14`, `15`, `16`, `17`, and `18`. `19` is rolling out and is accepted only in regions where it is enabled; requesting it elsewhere returns an error. Default: `18` - `store_passwords` (boolean, optional) Whether or not passwords are stored for roles in the Neon project. Storing passwords facilitates access to Neon features that require authorization. - `history_retention_seconds` (integer, optional, format: int32) History window (point-in-time restore range) for all branches, in seconds. `0` disables it. Default 1 day (Free: 6 hours). Maximum depends on plan: Free 6 hours (21600), Launch 7 days (604800), Scale 30 days (2592000). - `org_id` (string, optional) ID of the organization that will own the project.

MCP Tool: `create_project` Create a new Neon project with a default database and branch. If someone is trying to create a database, use this tool. Returns a connection string for the new project automatically. Supports optional `org_id` (assign to a specific organization) and `name` parameters. - `name` (string, optional) An optional name of the project to create. - `org_id` (string, optional) Create project in a specific organization. ## Console Console path: Organization → Projects → New project ## Errors **default** General Error. The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received. - If no response is returned from the API, a network error or timeout likely occurred. - In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results. The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**. The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout. Any request that returns a `503 Service Unavailable` response is always safe to retry. Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress. - `request_id` (string, optional) Unique identifier for the request, useful for debugging. You can set this value manually by including an `X-Request-ID` header in the request. If not provided, the value will be generated automatically. - `code` (string, required) Machine-readable code classifying the error type. See `message` for a human-readable explanation. Default: \`\` - `message` (string, required) Error message ## Related pages - [Accept a project transfer request](./apis-sdks-reference-api-projects-accept-project-transfer-request.md) - [Add JWKS URL](./apis-sdks-reference-api-projects-add-project-jwks.md) - [Create a project transfer request](./apis-sdks-reference-api-projects-create-project-transfer-request.md) - [Delete JWKS URL](./apis-sdks-reference-api-projects-delete-project-jwks.md) - [Delete project](./apis-sdks-reference-api-projects-delete-project.md) - [Delete VPC endpoint restriction](./apis-sdks-reference-api-projects-delete-project-vpc-endpoint.md) - [Grant project access](./apis-sdks-reference-api-projects-grant-permission-to-project.md) - [List available shared preload libraries](./apis-sdks-reference-api-projects-get-available-preload-libraries.md) - [List JWKS URLs](./apis-sdks-reference-api-projects-get-project-jwks.md) - [List org members and their project roles](./apis-sdks-reference-api-projects-list-project-members.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
