How do I create a Neon API Key?

Log in to the [**Neon Console**](https://console.neon.tech), go to **Account Settings** > **API Keys** (or **Organization Settings** > **API Keys**), click **Create New**, choose the scope (Personal, Organization or Project-scoped), and copy the token immediately — it is shown only once.

What is a Neon branch and how does branching work?

A Neon branch is an isolated PostgreSQL environment with its own compute, databases and roles. Branches are created instantly using copy-on-write cloning from a parent branch (default: primary). This means zero data copy and instant provisioning. Each branch gets its own compute endpoints and can have different PostgreSQL schemas and data.

Can I get a ready-to-use connection URI?

Yes! Use the `get_connection_uri` tool with your project_id and optionally a branch_id. It returns a complete PostgreSQL connection string (postgres://user:password@host/dbname) ready to use with psql, ORMs or application clients.

Can the agent delete projects and branches?

Yes, the agent has tools to delete both projects and branches. Deleting a project marks it for recovery (7-day grace period) but destroys all associated data. Deleting a branch is irreversible and removes all its databases, roles and endpoints. Use caution when executing these actions.

Neon MCP Tools for Cursor (17)

These 17 tools become available when you connect Neon to Cursor via MCP:

create_branch

Optionally set a human-readable name and a parent branch ID to clone from (if omitted, clones from the project's primary branch). Branches are created instantly with zero data copy overhead. Returns the new branch along with its initial endpoints, databases and roles. Create a new branch in a Neon project

create_database

Requires the database name. Optionally set the owner role name (must exist in the branch — see list_roles). Returns the new database metadata. Create a new database in a Neon branch

create_endpoint

Specify the endpoint type: "read_write" for full access or "read_only" for read replicas. A branch can have at most one read_write endpoint. Returns the new endpoint with its connection host and configuration. Create a compute endpoint for a Neon branch

create_project

Optionally set a human-readable name, AWS region (e.g. "aws-us-east-2", "aws-eu-central-1") and PostgreSQL version (15, 16, 17). A default branch, database and read-write endpoint are automatically provisioned. Returns the new project along with its initial connection URIs, roles, databases and endpoints. Create a new Neon project

create_role

The role can be used to authenticate database connections and own databases. Provide the project_id, branch_id and desired role name. Returns the new role metadata including the generated password. Create a new database role in a Neon branch

delete_branch

The primary branch cannot be deleted — set another branch as primary first. Provide the project_id and branch_id. WARNING: this action is irreversible and destroys all branch data. Delete a Neon branch

delete_project

The project is recoverable for 7 days via the Neon console. All associated branches, databases, endpoints and data are deleted. Provide the project_id. WARNING: this action destroys all data in the project. Delete a Neon project

get_branch

Provide both the project_id and branch_id. Get details for a specific Neon branch

get_connection_uri

Optionally specify a branch_id to get the URI for a specific branch (defaults to the primary branch). The URI includes the host, database name, role and password. Use this to connect psql, ORM tools or application clients. Get a PostgreSQL connection URI for a Neon project

get_project

Provide the project_id (e.g. "purple-shape-411361") obtained from list_projects. Get details for a specific Neon project

list_branches

Each branch is an isolated PostgreSQL environment with its own compute, databases and roles. Branches can be created from any point-in-time using copy-on-write cloning. Returns branch ID, name, parent ID, primary status, creation date and current state. Use the project_id from list_projects. List branches in a Neon project

list_databases

Each database has a name, owner role and creation metadata. Use the project_id and branch_id to scope the query. List databases in a Neon branch

list_endpoints

Each endpoint has a type (read_write or read_only), host address, current state (active, idle, suspended) and autoscaling configuration. A branch can have at most one read_write endpoint. Use the project_id and branch_id. List compute endpoints for a Neon branch

list_projects

Each project is a workspace that contains branches, compute endpoints, databases and roles. Returns project ID, name, region, PostgreSQL version, creation date and resource usage metadata. Use this as the starting point for all Neon operations — you need a project_id to manage branches, databases or endpoints. List all Neon projects

list_roles

Each role has a name, creation date and privilege metadata. Use the project_id and branch_id to scope the query. Roles are used to authenticate database connections and control access. List database roles in a Neon branch

set_primary_branch

The primary branch is the default source for new branch cloning and receives the default read-write compute endpoint. Provide the project_id and the branch_id to promote. Set a branch as the primary branch of a Neon project

Neon + Cursor FAQ

Common questions about integrating Neon MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design — tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
