MCP integration

Forecast from your AI chat.

Connect Pretick once. Ask your agent to forecast your numbers using your existing credit.

1. Add Pretick to ChatGPT

In ChatGPT, enable developer mode if required by your account, then create a custom app or plugin with the following MCP server URL. Choose OAuth authentication; leave client ID and client secret empty for automatic registration.

https://pretick.ai/mcp

The interface may label this Apps, Connectors or Plugins. Custom MCP availability depends on your plan and workspace settings. See OpenAI's connection guide. Adding a URL to an ordinary chat does not install the connection.

2. Connect your account

ChatGPT opens a connection page on pretick.ai. Paste the Pretick API key from your email into that page and approve access. Your API key stays with Pretick; the agent receives a separate access token. You can use your existing key and balance, including trial credit.

No key yet? Get five free forecasts. Paid forecasts cost $0.02 each. Connecting, checking credit and reading examples are free. This connection cannot charge your card or purchase more credit.

3. Ask for a forecast

Use Pretick to forecast the next 6 values from:
102, 108, 111, 104, 99, 106

Show the input as a solid line and the forecast as a dotted line.
Include copyable predictions and explain the uncertainty.

Select or enable the Pretick app in your conversation if ChatGPT does not select it automatically. Your client may ask for confirmation before a tool spends credit.

Available tools

Tool	What it does
`forecast`	Pasted numbers, numeric arrays, or time/value pairs. Defaults to the same number of output observations.
`forecast_advanced`	Multiple columns, target selection, frequency and quantiles.
`get_usage`	Account balance and the latest 100 request accounting records. Free.

Request fields and limits match the HTTP API. The MCP server also exposes the validated request examples as a resource. It uses the same inference, billing and refund paths.

Other MCP clients

Use Streamable HTTP at https://pretick.ai/mcp. OAuth discovery, dynamic client registration, authorization-code flow with S256 PKCE, refresh and revocation are supported. The resource is exactly https://pretick.ai/mcp and the scope is pretick:use. Clients that support securely configured headers can instead use Authorization: Bearer YOUR_PRETICK_API_KEY. Never put keys in the URL or tool arguments.

Disconnect and troubleshoot

Remove or disconnect Pretick in your client to stop using it. OAuth clients can revoke their access or refresh token at POST https://pretick.ai/oauth/revoke with form fields token and client_id. To revoke every MCP connection yourself, use Manage connections. Access tokens expire after one hour; refresh access lasts up to 30 days before reconnecting.

If an old connection still says MCP is planned, refresh its tools or remove and re-add it. If you receive 401, reconnect; 402 means top up with the same email at pricing. After a timeout, check usage before retrying: every successful call is separately billable. A GET request to the MCP URL returns 405 because protocol requests use POST.

This is a live custom MCP integration; it is not a listing in the ChatGPT directory.
