 ## Model Context Protocol (MCP) Server
+
+The [Model Context Protocol](https://modelcontextprotocol.io/introduction) (MCP)
+is a standard for making tools, data, and prompts available to AI models. It can
+be especially useful in bringing context on your stack into coding assistants.
+
+Version 25 of Dgraph introduces two MCP servers with common tools for AI coding
+assistants:
+
+- `mcp` – a server that provides tools and data from your Dgraph cluster
+- `mcp-ro` – a server that provides tools and data from your Dgraph cluster in
+  read-only mode
+
+### Configuration
+
+To add the MCP server to your coding assistant, add the following to your
+configuration file:
+
+When using Hypermode Graphs, the MCP configuration is available on the graph
+details screen in the console.
+
+<CodeGroup>
+
+```json Hypermode
+{
+  "mcpServers": {
+    "hypermode-graph": {
+      "command": "npx",
+      "args": [
+        "mcp-remote",
+        "https://<graph-workspace>.hypermode.host/mcp/sse",
+        "--header",
+        "Authorization: Bearer <bearer-token>"
+      ]
+    }
+  }
+}
+```
+
+```json local
+{
+  "mcpServers": {
+    "dgraph": {
+      "command": "npx",
+      "args": ["mcp-remote", "https://localhost:9080/mcp/sse"]
+    }
+  }
+}
+```
+
+</CodeGroup>
+
+<Tip>
+  We're continuing to refine the resources available on the MCP servers. Please
+  share feedback via [Discord](https://discord.hypermode.com) or
+  [GitHub](https://github.com/hypermodeinc/dgraph).
+</Tip>
+
+### Tools
+
+The MCP servers provide the following tools:
+
+- `Get-Schema` – fetch the schema of your cluster
+- `Run-Query` – run a query on your cluster
+- `Run-Mutation` – run a mutation on your cluster
+- `Alter-Schema` – modify the schema of your cluster
+- `Get-Common-Queries` – provides reference queries to aide in query syntax
+
+### Prompt
+
+For clients that support prompts over the MCP protocol, a prompt is available to
+provide an introduction to the agent.
+
+The full text of the prompt is
+[available in the Dgraph repo](https://github.com/hypermodeinc/dgraph/blob/8a774a03ac2558ad027bd86ead8b0059d3bfa3f5/dgraph/cmd/mcp/prompt.txt).
