# neuron_switch_instance

Switch the MCP server to target a different Neuron backend instance. Auth tokens are preserved per instance — if you've previously logged in to an instance, switching back restores your session automatically. Call with no args to list known instances and see which is active.

## Facts

- Tool: `neuron_switch_instance`
- Server: Neuron (`neuron-mcp-server`) — https://policylayer.com/tools/io-github-conquext-neuron.md
- Install: `npx -y neuron-mcp-server`
- Homepage: https://github.com/conquext/neuron
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server CORS policy: *
- Server rate-limited: no
- Parameters: 1
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `url` | string | no | Base API URL of the Neuron instance (e.g., 'https://api.client.com/api/v1'). Omit to list known instances. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "neuron_switch_instance",
    "arguments": {}
  }
}
```

## Why neuron_switch_instance is rated Medium

An AI agent can call neuron_switch_instance faster than any human can review: one bad instruction and it creates or modifies resources in Neuron by the hundred, each call as confident as the last.

Risk signals: Accepts URL/endpoint input (url)

## Use case

AI agents use neuron_switch_instance to create or update resources in Neuron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuron environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Neuron:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "neuron_switch_instance": {
      "limits": [
        {
          "counter": "neuron_switch_instance_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
