Mythex

Mythex AI ऐप बिल्डर के लिए रिमोट MCP सर्वर: Claude, Cursor या Codex क्लाउड सैंडबॉक्स में प्रोजेक्ट बनाते हैं, कोड संपादित करते हैं और bash चलाते हैं, प्रीव्यू करते हैं, Postgres डेटाबेस जोड़ते हैं और लाइव URL पर प्रकाशित करते हैं।

MCP (Claude, Codex, Cursor)

How to connect Claude, Codex or Cursor to Mythex over MCP — paste the MCP URL, click Connect, approve on Mythex. Tool calls need a Pro account and credits.

MCP — build from Claude, Codex, or Cursor

Mythex exposes a remote MCP server. External agents (Claude, Cursor, Codex) code in your cloud sandbox; Mythex provides the VM, preview, and publish.

The simple flow (recommended)

  1. Copy your MCP URL. It is in two places, whichever you reach first:

    • Account settings → MCP / Claude
    • Connectors (left sidebar) → Custom MCP, at the foot of the panel

    Production: https://mcp.mythex.ai/mcp

    The MCP URL under Connectors → Custom MCP

  2. In the client, add that URL as a custom MCP / connector

  3. Click Connect

  4. Your browser opens Mythex /mcp/consent — sign in if needed, then Allow access or Deny

  5. You’re done. Chat in Claude/Cursor and build

Anyone can Connect. Tool calls need a Mythex Pro account (and credits for sandbox time). Free can still Allow access; tools show an upgrade panel until the account is Pro.

Claude

Settings → Connectors → Add custom connector → paste MCP URL → Connect → approve on Mythex.

Cursor

Add the server with only the URL (Settings → MCP, or .cursor/mcp.json):

{
  "mcpServers": {
    "mythex": {
      "url": "https://mcp.mythex.ai/mcp"
    }
  }
}

Toggle the server on → Connect when Cursor prompts → approve on Mythex.

Local dev can use http://localhost:4000/mcp the same way.

Requirements for tools

  • Pro plan (Connect works without it; tools return an upgrade error)
  • Credits on your balance (empty balance → sandbox wake refused / sandboxes pause)

What the client can do

  • Create / open projects and wake sandboxes
  • Read, write, edit, search files; run bash
  • Preview via set_run_config / start / logs
  • Env keys (set secrets you provide — values are not listed back)
  • Database, storage, publish, checkpoints
  • Browser run, web/media helpers, export/import, GitHub, domains

Tool results include a workspace_url (https://mythex.ai/p/{id}?from=mcp). Open it to watch the live preview and progress in Mythex while the client works in Cursor/Claude.

If you run out of credits (or need Pro), the tool returns an upgrade_url and Cursor shows a Mythex panel in chat (pricing / credits) — the same idea as inline image and video previews. Open the URL if you want checkout in the browser.

Preview tools (set_run_config, start_preview, get_preview) return preview_url for the in-chat live iframe. browser_run attaches Playwright screenshot() PNGs as images in chat (Claude/Cursor can display them).

What stays private

  • Mythex agent system prompts and internals
  • Platform secrets and other users’ projects
  • Raw secret values via list_env_keys (keys only)

Credits

  • The external model is billed by that provider (Claude / Cursor / etc.)
  • Mythex credits pay for live sandbox time and published hosting
  • Empty balance → sandbox wake refused / sandboxes pause
