# MCP on a Neuron

> Connect an AI development client to capabilities exposed by a Neuron

Model Context Protocol (MCP) lets an AI client call tools and read resources exposed by a Neuron. You connect to one capability at a time and sign in through the Neuron's OAuth service.

<Warning>
  MCP servers differ by deployment. Ask the Neuron operator for the endpoint, OAuth client settings, required role, and list of enabled tools.
</Warning>

## Common MCP endpoints

| Endpoint        | Use it to                                                              |
| --------------- | ---------------------------------------------------------------------- |
| `/MCP/Files`    | List, read, search, and—when permitted—change files in account storage |
| `/MCP/EventLog` | Search or write operational events                                     |
| `/MCP/Content`  | Fetch Internet content through the Neuron                              |
| `/MCP/XMPP`     | Work with messages and contacts over XMPP                              |

There is no documented combined `/MCP` endpoint. A package can add other endpoints, so use the exact URL supplied by the Neuron operator.

## What you need

You do **not** need the Neuron source code. You need:

* a reachable Neuron URL;
* an MCP endpoint;
* an OAuth client ID, or confirmation that dynamic client registration is enabled;
* an account or sign-in flow with the required role.

For a Neuron running on your machine, you configure access yourself. For another Neuron, its operator provides these values and grants access.

## Choose another tool when

The listed servers do not create or install Neuron packages, author contracts, or issue tokens. Use the [package tools](/neuron-development/quickstart), [LegalLab](/contracts/legallab-quickstart), or [Agent API](/contracts/agent-api-quickstart) for those tasks.
