Connect to the CockroachDB Cloud MCP Server

On this page Carat arrow pointing down

CockroachDB Cloud includes a managed Model Context Protocol (MCP) server that enables AI coding tools and AI agents to access a cluster. AI tools can explore live schemas and run queries against a cluster using OAuth or API key authentication. A user can interact with their cluster using natural language prompts to perform read and write operations such as listing tables, executing SELECT statements, and inserting rows into a table.

This page explains how to connect AI tools to the CockroachDB Cloud MCP server, including detailed instructions for the following tools:

  • Claude Code
  • Cursor
  • Cline
  • Github Copilot

Before you begin

Connect to the MCP Server

Warning:

Cockroach Labs recommends using OAuth to connect to the Cloud MCP server, as short-lived tokens are more secure than long-lived tokens.

AI tools with cluster access can execute operations on your behalf. When first connecting an AI tool to CockroachDB, consider starting with a staging cluster to understand the tool's behavior before granting it access to production data.

Step 1. Choose your authentication method

Step 2. Update tool configuration

Cockroach Labs enables access to its CockroachDB Cloud MCP server via HTTP transport (using HTTPS).

Different AI tools might have slightly different ways of connecting to an MCP server via HTTP. This will normally involve adding a JSON snippet to a configuration file, which will include:

  • The MCP server URL: https://cockroachlabs.cloud/mcp
  • Your Cluster ID

Different AI tools might have slightly different ways of connecting to an MCP server via HTTP. This will normally involve adding a JSON snippet to a configuration file, which will include:

  • The MCP server URL: https://cockroachlabs.cloud/mcp
  • Your Cluster ID
  • A header containing a bearer token: "Authorization: Bearer {your-service-account-api-key}". This should contain the secret key generated when creating your service account.

The specific JSON snippet might look slightly different for each tool, and the tool might offer CLI commands to simplify the configuration process.

The following are instructions for how to update the configuration of some common AI tools. For other tools, read the documentation for those tools.

Option 1. Use the Claude Code CLI

  1. Copy the following command:

    icon/buttons/copy
    claude mcp add cockroachdb-cloud https://cockroachlabs.cloud/mcp --transport http --header "mcp-cluster-id: {your-cluster-id}"
    
  2. Paste the command in your terminal, replacing the {your-cluster-id} placeholder. Run the command.

Option 2: Manually modify JSON

  1. Copy the following JSON snippet:

    icon/buttons/copy
    "cockroachdb-cloud": {
      "type": "http",
      "url": "https://cockroachlabs.cloud/mcp",
      "headers": {
        "mcp-cluster-id": "{your-cluster-id}"
      }
    }
    
  2. Open .claude.json.

  3. Find "mcpServers". Include the JSON snippet in the list of MCP servers, replacing the {your-cluster-id} placeholder.

While it's possible to use multiple MCP server connections to connect your tool to multiple clusters at once, or to connect to the same cluster using different authentication methods, Cockroach Labs recommends connecting to one cluster using one authentication method.

Step 3. Connect and authenticate

  1. After configuring the MCP server, run the following command in your terminal:

    icon/buttons/copy
    claude /mcp
    
  2. Select the new server configuration cockroachdb-cloud and select Authenticate.

  3. If you are not currently logged in to your CockroachDB Cloud account, you will be directed to the login page in your browser. Log in.

  4. If you are a member of multiple CockroachDB Cloud organizations, you wil be directed to the Organization Selection modal in your browser. Select the organization associated with the cluster that you have included in the tool configuration.

  5. You will be directed to the Authorize MCP Access modal in your browser. This modal will ask you to grant read and/or write permissions to this MCP server connection. Select one or both options, then click Authorize.

  5. You will be directed to the Authorize MCP Access modal in your browser. This modal will ask you to grant read and/or write permissions to this MCP server connection. Select one or both options, then click Authorize.

If the provided API key is active, there should be no futher authorization steps. The MCP server connection's access permissions are determined by the role(s) associated with this service account.

Use the MCP server

The CockroachDB Cloud MCP server provides several tools that enable you to read cluster data and metadata:

Tool Description
list_clusters List all accessible clusters.
get_cluster Get detailed cluster information.
list_databases List databases in the cluster.
list_tables List tables in a database.
get_table_schema Get detailed schema for a table.
select_query Execute a SELECT statement.
explain_query Execute an EXPLAIN statement.
show_running_queries List currently executing queries.

There are also several tools that enable you to write cluster data:

Tool Description
create_database Create a new database.
create_table Create a new table.
insert_rows Insert rows into a table.

The tool will only read or write to the cluster specified by the configuration that you updated in Step 2.

Use natural language prompts to read from and write to the cluster. These prompts do not need to reference the names of the tools. Prompts can be simple, for example:

List all of the tables in the movr database.

They can also be complex and conversational, for example:

I need to add a service appointments table to the movr database. I need to track when customers schedule service appointments for their vehicles.

For the schema, I'm thinking we need:
- Appointment ID (primary key)
- Customer reference (foreign key to movr.customers)
- Vehicle reference (foreign key to movr.vehicles)
- Appointment date/time
- Service type (oil change, inspection, repair, etc.)
- Status (scheduled, completed, cancelled, no-show)
- Assigned technician (foreign key to movr.technicians)
- Estimated cost
- Notes

Let's include a secondary index on the status column.

Show me the CREATE TABLE statement so that we can talk it through before you actually create the table.
