# Error handling

If something goes wrong, the MCP Server will return clear error messages. Common scenarios include:

* **Authentication errors**: Your session has expired. Re-authorise through the admin panel to reconnect.
* **Invalid parameters**: The AI will receive a descriptive error and can adjust its query automatically.
* **Not allowed by this connection:** The AI tried something outside the access levels chosen when the connection was authorized. Reconnect and select the access you need.
* **Not found or not authorised:** Requesting a resource (e.g. a campaign) that does not exist or belongs to another account returns a clear error rather than empty data.
* **Rate limits**: If you exceed the API rate limit, you will be informed and can retry after a short wait.
* **Service unavailable**: If the ExoClick API is temporarily unreachable, the error message will indicate this.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.exoclick.com/mcp/exoclick-mcp-error.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
