# Connecting your own tools (MCP)

## Connecting your own tools (MCP)

Use MCP when an assistant should use your own tools.

This is available on **Agent** and **Live**.

### What does MCP let you do?

You can connect your own MCP server to an assistant.

Replai reads the tools that server offers.

Then you choose which tools that assistant can use.

### What kinds of tools can you connect?

Connected tools can:

* Look up information in your systems
* Start an approved workflow
* Take an action when the assistant has permission

### How do tool permissions work?

Replai does not expose every tool automatically.

You choose which tools to allow for each assistant.

The assistant can use only the tools you allow.

### How do approvals work?

Consequential tool actions still require approval.

Replai shows what the action will do before it runs.

If the action changes data, charges money, or has side effects, you must approve it first.

If you decline, the action is canceled.

### Is this available on Answer?

No.

**Answer** is for grounded answers only.

It does not include MCP or other tool capabilities.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://replai-1.gitbook.io/replai-docs/features-by-tier/connecting-your-own-tools-mcp.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
