## Using AI on The Graph

Instead of relying on static datasets or centralized APIs, you can now use our AI-native tooling via the [Subgraph MCP](/content/docs/en/subgraphs/subgraph-mcp/introduction/index.html), [Substreams MCP](/content/docs/en/substreams/substreams-mcp/search/index.html), and agent skills for both Subgraphs and Substreams.

### Why Use Onchain Data with AI?

Using onchain data with AI unlocks powerful new ways to interact with and understand blockchain ecosystems.

## AI for Developers

You can use AI to interact directly with The Graph’s data through your agents or build AI-powered applications on top of it. This streamlines development and opens up more intuitive, dynamic use cases.

### Enable Natural Language Access to Onchain Data

[Model Context Protocol⁠](https://modelcontextprotocol.io/introduction) (MCP) servers connect to Claude, Cline, and Cursor. They enable models to understand, query, and interact with structured onchain data using natural language. MCPs remove the need to write low-level queries or interact with APIs directly.

Agent Skills extend AI coding assistants like Claude Code and Cursor with deep, specialized knowledge of The Graph’s protocols. This covers development patterns, best practices, and debugging techniques out of the box.

### Subgraph MCP

The [Subgraph MCP](/content/docs/en/subgraphs/subgraph-mcp/introduction/index.html) server connects models to Subgraphs on The Graph Network. It allows language models to explore Subgraph schemas, execute GraphQL queries, find relevant Subgraphs by keyword or contract, and surface usage metrics using natural language.

#### Benefits of Using Subgraph MCP

- Query Subgraphs and token data using natural language
- Access GraphQL schemas and token metadata without manual queries
- Find Subgraphs by keyword or contract and check 30-day usage
- Retrieve real-time data from The Graph and onchain token sources

### Substreams MCP

The [Substreams MCP](/content/docs/en/substreams/substreams-mcp/search/index.html) server lets AI agents search, inspect, and analyze Substreams packages — from registry discovery to sink deployment. It supports dual transport for local clients and SSE/HTTP for remote agents.

#### Tools

| Tool                  | Description                                                                                              |
|-----------------------|----------------------------------------------------------------------------------------------------------|
| `search_substreams`   | Search the substreams.dev package registry by keyword, network, or sort order                           |
| `inspect_package`     | Inspect a `.spkg` file to see its full module graph, protobuf types, and metadata                       |
| `list_package_modules`| Lightweight alternative to `inspect_package` — returns module names, types, and inputs/outputs          |
| `get_sink_config`     | Analyze a package’s sink configuration and generate ready-to-run CLI commands                            |

#### Benefits of Using Substreams MCP

- Discover Substreams packages across any supported chain without leaving your AI assistant
- Inspect module graphs and protobuf schemas using natural language
- Generate deployment CLI commands automatically from sink configurations
