MCP Server

PromptOT MCP Server

Use PromptOT directly from Claude Desktop, Cursor, Codex CLI, ChatGPT, claude.ai, and any other Model Context Protocol-compatible AI tool. 23 MCP tools cover the full prompt lifecycle: list, create, edit, version, publish, and inspect prompts from inside your AI assistant.

What is MCP?

The Model Context Protocol is an open standard for connecting AI assistants to external tools and data sources. PromptOT's MCP server exposes our prompt management API as a set of typed tools that any MCP-compatible client can call. Once installed, the AI model can list your prompts, edit blocks, save draft versions, publish to production, and run test cases — all through normal conversation.

The server ships in two forms: a local stdio binary distributed via npm (npx @prompt-ot/mcp) for desktop clients, and a hosted HTTP transport at mcp.promptot.com for browser-based clients that authenticate via OAuth.

Quick start

01

Generate an MCP key

From your dashboard, open any project's API Keys page and click "Generate MCP Key" in the MCP Server card. Optionally enable AI features if you want playground/evals/AI rewrites.

02

Paste the install snippet

Click your client (Claude Desktop, Cursor, Codex CLI, etc.) and copy the snippet. Paste it into your client's MCP config file at the path shown.

03

Restart and ask your AI

Restart your AI client. The PromptOT tools become available automatically. Try "List my PromptOT prompts" or "Create a new customer support prompt".
