+# Makerkit MCP Server
+
+The Makerkit MCP Server provides tools to AI Agents for working with the codebase.
+
+## Build MCP Server
+
+Run the command:
+
+```bash
+pnpm --filter "@kit/mcp-server" build
+```
+
+The command will build the MCP Server at `packages/mcp-server/build/index.js`.
+
+## Adding MCP Servers to AI Coding tools
+
+Before getting started, retrieve the absolute path to the `index.js` file created above. You can normally do this in your IDE by right-clicking the `index.js` file and selecting `Copy Path`.
+
+I will reference this as `<full-path>` in the steps below: please replace it with the full path to your `index.js`.
+
+### Claude Code
+
+Run the command below:
+
+```bash
+claude mcp add makerkit node <full-path>
+```
+
+Restart Claude Code. If no errors appear, the MCP should be correctly configured.
+
+### Codex
+
+Open the Codex YAML config and add the following:
+
+```
+[mcp_servers.makerkit]
+command = "node"
+args = ["<full-path>"]
+```
+
+### Cursor
+
+Open the `mcp.json` config in Cursor and add the following config:
+
+```json
+{
+  "mcpServers": {
+    "makerkit": {
+      "command": "node",
+      "args": ["<full-path>"]
+    }
+  }
+}
+```
+
+## Additional MCP Servers
+
+I strongly suggest using [the Postgres MCP Server](https://github.com/modelcontextprotocol/servers-archived/tree/main/src/postgres) that allows AI Agents to understand the structure of your Database.
