+metaTitle: Using Prisma with Codex
+metaDescription: Install the Prisma Codex plugin to add Prisma ORM skills and the remote Prisma MCP server to Codex.
+---
+
+[Codex](https://developers.openai.com/codex/) is an AI coding agent from OpenAI. You can use the Prisma Codex plugin to give Codex Prisma-specific guidance and connect it to the Prisma MCP server for Prisma Postgres workflows.
+
+The Prisma Codex plugin includes:
+
+- Prisma CLI guidance
+- Prisma Client API guidance
+- Database setup guidance
+- Prisma Postgres guidance
+- Prisma ORM upgrade guidance
+- The remote Prisma MCP server configuration
+
+## Install the Prisma Codex plugin
+
+Add the Prisma plugin marketplace to Codex:
+
+```bash title="Terminal"
+codex plugin marketplace add prisma/codex-plugin
+```
+
+Then restart Codex and install the plugin:
+
+1. Open the Codex plugin directory.
+1. Select the `Prisma` marketplace.
+1. Install the `Prisma` plugin.
+
+If your Codex CLI does not recognize the `plugin marketplace add` command, update Codex and try again.
+
+## Prisma MCP server
+
+The plugin configures the official remote Prisma MCP server:
+
+```json title="Prisma MCP server"
+{
+  "mcpServers": {
+    "prisma": {
+      "type": "http",
+      "url": "https://mcp.prisma.io/mcp"
+    }
+  }
+}
+```
+
+When Codex first uses the Prisma MCP server, it authenticates with Prisma Console and asks you to choose the workspace Codex can access.
+
+With the Prisma MCP server, Codex can help you:
+
+- List Prisma Postgres databases in your workspace.
+- Create Prisma Postgres databases.
+- Create backups and recovery databases.
+- Create and manage connection strings.
+- Execute SQL queries.
+- Introspect database schemas.
+
+## Example prompts
+
+After installing the plugin, try prompts like:
+
+```text
+Set up Prisma ORM in this project with the right database adapter.
+```
+
+```text
+Use Prisma MCP to list my Prisma Postgres databases.
+```
+
+```text
+Inspect this project and upgrade it to Prisma ORM 7.
+```
+
+```text
+Use Prisma MCP to inspect my database schema and plan a migration.
+```
+
+## Safety
+
+Prisma ORM includes safety checks for destructive commands run through AI coding agents. For example, Prisma blocks destructive commands such as `prisma migrate reset --force` unless the AI agent asks for explicit user consent and passes that consent back to Prisma.
+
+This helps prevent accidental data loss when using Codex or another AI agent with Prisma projects.
