@prompt-ot/mcp

Model Context Protocol server for PromptOT.

Use PromptOT directly from Claude Desktop, Cursor, Codex CLI, ChatGPT, claude.ai, or any other MCP-compatible AI tool. The server exposes ~35 tools for managing prompts, blocks, variables, versions, test cases, and more — all gated by scoped API keys.

Install

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "promptot": {
      "command": "npx",
      "args": ["-y", "@prompt-ot/mcp"],
      "env": {
        "PROMPTOT_API_KEY": "pot_...",
        "PROMPTOT_MCP_CLIENT": "claude-desktop"
      }
    }
  }
}

Generate your API key from the PromptOT dashboard → project → API Keys → "Generate MCP Key".

Cursor

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in your workspace root):

{
  "mcpServers": {
    "promptot": {
      "command": "npx",
      "args": ["-y", "@prompt-ot/mcp"],
      "env": {
        "PROMPTOT_API_KEY": "pot_...",
        "PROMPTOT_MCP_CLIENT": "cursor"
      }
    }
  }
}

Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.promptot]
command = "npx"
args = ["-y", "@prompt-ot/mcp"]
env = { PROMPTOT_API_KEY = "pot_...", PROMPTOT_MCP_CLIENT = "codex-cli" }
