# CockroachDB and AI

export const InternalLink = ({version, path = "", children, ...props}) => {
  let detectedVersion = version || "stable";
  if (typeof window !== 'undefined' && !version) {
    const match = window.location.pathname.match(/\/docs\/([^/]+)/);
    if (match) {
      detectedVersion = match[1];
    }
  }
  const normalizedPath = path.startsWith("/") ? path.slice(1) : path;
  return <a href={`/docs/${detectedVersion}/${normalizedPath}`} {...props}>
      {children}
    </a>;
};

CockroachDB supports AI in two primary ways: as a platform that enables AI-assisted development and administration, and as a data store for AI applications.

**Support for AI-assisted workflows**: CockroachDB integrates with AI development tools, including Claude Code, Cursor, and GitHub Copilot in VS Code. [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) servers provide access to CockroachDB Cloud clusters and CockroachDB documentation. The Agent Skills repository encodes operational workflows in a machine-executable format.

For more information, refer to [Support for AI-assisted workflows](#support-for-ai-assisted-workflows).

**A data store for AI applications**: CockroachDB can serve as the system of record and the retrieval engine for AI applications. It combines native support for vector data and similarity search with strongly consistent transactions, horizontal scalability, and multi-region deployments. These capabilities support storing vector embeddings, agent state, conversation histories, and other AI-related data alongside relational data.

For more information, refer to [CockroachDB as a data store for AI applications](#cockroachdb-as-a-data-store-for-ai-applications).

## Support for AI-assisted workflows

CockroachDB enables your AI development tools to work directly with CockroachDB and CockroachDB Cloud. CockroachDB provides the following functionality to support AI-assisted deployment and maintenance of clusters, and AI-assisted development of applications:

* Cluster-level read and write access via the <InternalLink version="cockroachcloud" path="connect-to-the-cockroachdb-cloud-mcp-server">CockroachDB Cloud MCP server</InternalLink>.
* Operational workflows encoded as <InternalLink path="agent-skills">Agent Skills for CockroachDB</InternalLink>.
* Command-line automation with the <InternalLink version="cockroachcloud" path="ccloud-get-started">`ccloud` CLI</InternalLink>, designed to be compatible with AI agents.
* Access to the Cockroach Labs public documentation via the <InternalLink path="docs-mcp-integration">CockroachDB Docs MCP server</InternalLink>.

The following sections provide an overview of these tools.

### CockroachDB Cloud MCP server

The <InternalLink version="cockroachcloud" path="connect-to-the-cockroachdb-cloud-mcp-server">CockroachDB Cloud MCP server</InternalLink> is a managed endpoint in CockroachDB Cloud that exposes a set of tools for inspecting and querying your clusters from your AI tools. These tools let your AI assistants list <InternalLink path="show-databases">databases</InternalLink> and <InternalLink path="show-tables">tables</InternalLink>, describe <InternalLink path="show-schemas">schemas</InternalLink> and <InternalLink path="show-index">indexes</InternalLink>, inspect cluster health and running queries, and run read-only SQL and <InternalLink path="explain">`EXPLAIN`</InternalLink> statements. When explicitly enabled, they can also <InternalLink path="create-database">create databases</InternalLink>, <InternalLink path="create-table">create tables</InternalLink>, and <InternalLink path="insert">insert rows</InternalLink>.

This endpoint allows you to manage and modify a CockroachDB Cloud cluster using natural language prompts. For example, you could use the following prompt to instruct your AI tool to interface with the cluster:

```text theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
List all of the tables in the demo_db database.
```

### Agent Skills for CockroachDB

<InternalLink path="agent-skills">Agent Skills for CockroachDB</InternalLink> are small, structured capabilities that encode CockroachDB operational expertise in a machine-executable format. These skills live in the public [cockroachdb-skills](https://github.com/cockroachlabs/cockroachdb-skills) repository and follow the [Agent Skills Specification](https://agentskills.io/specification), with defined inputs, outputs, and safety guardrails.

Each skill focuses on a specific task, such as auditing user privileges, triaging live SQL activity, validating production readiness, or checking backup and disaster recovery posture. Skills are organized into domains like onboarding and migrations, application development, performance and scaling, operations and lifecycle, resilience and disaster recovery, observability and diagnostics, security and governance, integrations, and cost management.

Your AI tools can consume these skills directly, so you can reuse the same operational workflows across different toolchains.

### `ccloud` command-line interface

The <InternalLink version="cockroachcloud" path="ccloud-get-started">`ccloud` CLI</InternalLink> is the command-line interface for CockroachDB Cloud. You can use the `ccloud` CLI to create clusters, manage networking (for example, IP allowlists), create SQL users, retrieve connection information, and more.

Because `ccloud` is text-based and follows a stable command structure, it is well-suited for AI tools and automations. An AI assistant can generate or run `ccloud` commands to set up clusters, rotate credentials, or retrieve connection URLs, while you keep access mediated through the CLI and existing Cloud authentication.

### CockroachDB Docs MCP server

The <InternalLink path="docs-mcp-integration">CockroachDB Docs MCP server</InternalLink> exposes the published CockroachDB documentation to your MCP-compatible tools over HTTP. After you add the server configuration to your client, your AI assistant can answer questions using the official documentation without leaving your editor. For example, you could use your AI tool to ask the following:

```text theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
How do table statistics get refreshed in CockroachDB?
```

An AI tool using the documentation MCP server can provide a response to this prompt informed by documentation pages such as <InternalLink path="cost-based-optimizer">Cost-Based Optimizer</InternalLink> and <InternalLink path="create-statistics">`CREATE STATISTICS`</InternalLink>.

This integration only provides access to CockroachDB product documentation. It does not connect to your clusters or data. It is intended to give your AI tools reliable product information while you develop and operate CockroachDB and CockroachDB Cloud.

## CockroachDB as a data store for AI applications

CockroachDB provides the database features needed to store and query AI-related data, including vector embeddings and agent state, with the same transactional guarantees as your other workloads.

### Vector search and RAG

AI applications often represent text, images, and other content as vector embeddings. These are numerical representations that capture semantic meaning. To find relevant information, AI applications need to search for vectors that are similar to a query vector, typically using distance metrics. This similarity search is fundamental to retrieval-augmented generation (RAG), semantic search, and recommendation systems.

CockroachDB has a <InternalLink path="vector">`VECTOR` data type</InternalLink> for storing fixed-length floating-point embeddings and supports similarity operators such as L2 distance (`<->`), inner product (`<#>`), and cosine distance (`<=>`). You can index vectors using <InternalLink path="create-index#create-vector-indexes">`CREATE VECTOR INDEX`</InternalLink> and combine them with other indexed columns.

You can store vector embeddings, relational data, and <InternalLink path="jsonb">JSON</InternalLink> metadata in the same table and query them together. For example:

```sql theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
SELECT id, name
FROM items
WHERE customer_id = 1
ORDER BY embedding <-> $query_vector
LIMIT 5;
```

RAG systems depend on fast and accurate retrieval of contextual data. CockroachDB's vector support enables you to implement RAG and semantic search patterns so that you can use CockroachDB as the data store for AI applications. <InternalLink path="vector-indexes">Vector indexes</InternalLink> enable efficient similarity searches over large datasets. You can store document embeddings in a cluster alongside the source documents, metadata, and access control information associated with those documents. When a user query comes in, you can use vector similarity operators to retrieve semantically relevant documents, filter by permissions, and return both the relevant context and any associated metadata in a single transaction.

See the [RAG tutorial](https://www.cockroachlabs.com/blog/tutorial-rag-with-cockroachdb) for a complete implementation example.

### AI agent state and workflow coordination

AI agents that perform autonomous operations require durable storage for execution state, workflow metadata, and operational history. These agents must track state transitions across multi-step processes, coordinate activities between concurrent executions, and ensure that operations can be safely retried or resumed after failures.

CockroachDB's <InternalLink path="transactions">transactional model</InternalLink> provides a foundation for storing agent state, execution history, and coordination metadata. <InternalLink path="demo-serializable">Serializable isolation</InternalLink> ensures that state transitions occur correctly even when multiple agents or processes attempt concurrent updates. The database's <InternalLink path="frequently-asked-questions">high availability</InternalLink> design allows agents to continue operating during node or region failures without requiring external coordination services.

### Scale, consistency, and governance

AI applications typically generate high data volumes, serve globally distributed users, and require both transactional correctness and operational durability. Conversation histories, vector embeddings, feature tables, and agent state accumulate quickly and are accessed across regions. These characteristics make AI workloads well-suited to CockroachDB's core design:

* CockroachDB scales horizontally by adding nodes to increase capacity.
* Data is automatically replicated and rebalanced across the cluster, so node failures do not require application-level failover.
* <InternalLink path="multiregion-overview">Multi-region deployments</InternalLink> place data closer to users and can enforce <InternalLink path="regional-tables">data locality</InternalLink> or residency requirements while maintaining strong consistency.

CockroachDB provides <InternalLink path="demo-serializable">serializable transactions</InternalLink> by default. Vector indexes participate in the same transaction and index maintenance model as other <InternalLink path="indexes">secondary indexes</InternalLink>, so similarity search results remain aligned with the underlying data. This applies to tables storing embeddings, relational records, and agent state.
