MCP server

LetzAI, inside your AI assistant.

Connect Claude, Cursor or any MCP client to LetzAI, then ask for what you need: an image, a clip, a voice-over, an upscale. It runs on your LetzAI account, with your models and your credits.

Server URL https://mcp.dev.letz.ai/mcp

Connect

Point your client at exactly the server URL above, including /mcp. You need a LetzAI account with credits; use the account for this environment, since development and production connections are separate.

Claude, on the web or desktop

Customize → Connectors → Add custom connector → URL https://mcp.dev.letz.ai/mcp.

Choose Sign in now and Use Claude’s published identity. Leave the OAuth client ID, client secret, and request headers empty. Click Connect, sign in to LetzAI, review the permissions and billing account, then approve the connection. No Anthropic API key is needed.

Then, in a conversation

Turn LetzAI on with + → Connectors. Ask it to list your models before your first generation. On Team or Enterprise, an organization owner adds the connector first; each person then connects their own account.

Cursor and other MCP clients

Add an MCP server with the URL https://mcp.dev.letz.ai/mcp. Sign in through OAuth if your client supports it. An integration token in the Authorization: Bearer YOUR_TOKEN header is also supported.

What you can ask

Talk in plain language; your assistant picks the tool.

Images

A red maple leaf on a white background, 3:4.

Edits

Take image <id> and make it a winter night.

Video

Animate this image into a five-second clip.

Sound

A warm voice-over that says “Welcome to LetzAI.”

Upscale

Upscale image <id> to 4×.

Your models

List my models, then make a portrait with the first one.

Canvas

Put my last three images on my canvas “Spring campaign”.

Your library

Show my last ten images. Is image <id> done yet?

Images come back as a link when they're ready. Video, edits, sound and upscales take longer: your assistant gets an id, and you can ask whether it's done. On an organization plan, say “charge my organization” to spend its credits.

Add the LetzAI skill

The connector gives your assistant the tools. The skill teaches it to use them well: the right model for the job, better prompts, and a price quote before anything expensive.

Claude Code, Cursor and other agents

Run npx skills add Letz-AI/letzai-skill and choose letzai.

Claude.ai

Download the skills/letzai folder from GitHub, zip it, and add it under Settings → Features.

Credits and help

Everything runs on your LetzAI account, exactly as on the website.

Generations spend credits: The same prices as on letz.ai. Top up there whenever you need to.
“Unauthorized” (401): Reconnect your LetzAI account in Claude. Check that the connector URL matches this environment exactly. For an integration token, check whether it has expired or been revoked.
“Out of credits” (402): Top up your credits on letz.ai, or switch to your organization's credits.
The tools don't appear: Check the URL and that the connector is turned on for the conversation, then restart the client.
Keeping access safe: A connection or integration token acts on your account. Treat a token like a password and revoke it anytime in LetzAI Settings. This server never stores either.
