Cline

This guide walks you through the integration of Subgraph Model Context Protocol⁠ (MCP) to access Subgraph data through natural language conversations with Cline.

Prerequisites

Configuration Steps

1. Open Configuration File

Create or edit your cline_mcp_settings.json file.

MCP Servers > Installed > Configure MCP Servers

2. Add Configuration

{  "mcpServers": {    "subgraph": {      "command": "npx",      "args": ["mcp-remote", "--header", "Authorization:${AUTH_HEADER}", "https://subgraphs.mcp.thegraph.com/sse"],      "env": {        "AUTH_HEADER": "Bearer GATEWAY_API_KEY"      }    }  }}

3. Add Your API Key

Replace GATEWAY_API_KEY with your API key from Subgraph Studio.

Using The Graph Resource in Cline

After configuring Cline:

  1. Restart Cline
  2. Start a new conversation
  3. Enable the Subgraph MCP from the context menu
  4. Add “Subgraph Server Instructions” as a resource to your chat context

Available Tools and Usage

The Subgraph MCP provides several tools for interacting with Subgraphs:

Schema Retrieval Tools

  • Get schema by deployment ID: Access the GraphQL schema using a deployment ID (0x…)
  • Get schema by Subgraph ID: Access the schema for the current deployment of a Subgraph (5zvR82…)
  • Get schema by IPFS hash: Access the schema using a Subgraph’s IPFS manifest hash (Qm…)

Query Execution Tools

  • Execute query by deployment ID: Run GraphQL queries against specific, immutable deployments
  • Execute query by Subgraph ID: Run GraphQL queries against the latest version of a Subgraph

Discovery Tools

  • Get top Subgraph deployments: Find the top 3 Subgraph deployments indexing a specific contract on a particular chain

Natural Language Queries

One of the most powerful features of the Subgraph MCP integration is the ability to ask questions in natural language. Cline will:

  1. Understand your goal (lookup, find Subgraphs, query, get schema)
  2. Find relevant deployments if needed
  3. Fetch and interpret the Subgraph schema
  4. Convert your question into an appropriate GraphQL query
  5. Execute the query and present the results in a readable format

Example Natural Language Queries

What are the pairs with maximum volume on deployment 0xde0a7b5368f846f7d863d9f64949b688ad9818243151d488b4c6b206145b9ea3?
Which tokens have the highest market cap in this Subgraph?
Show me the most recent 5 swaps for the USDC/ETH pair

Key Identifier Types

When working with Subgraphs, you’ll encounter different types of identifiers:

  • Subgraph ID (e.g., 5zvR82...): Logical identifier for a Subgraph
  • Deployment ID (e.g., 0x4d7c...): Identifier for a specific, immutable deployment
  • IPFS Hash (e.g., QmTZ8e...): Identifier for the manifest of a specific deployment
