WHAT IT DOES

What neuron_create_tool does on Neuron

AI agents use neuron_create_tool 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.

Parameter	Type	Required	Description
`name`	string	Yes	Human-readable name for the tool
`type`	string	Yes	Type of the tool integration (e.g., 'http', 'webhook')
`botId`	string	Yes	Unique identifier (UUID) of the bot to create the tool for
`config`	object	Yes	Tool configuration specifying the HTTP endpoint and request details
`authType`	string	—	Authentication type for the endpoint (e.g., 'bearer', 'basic', 'apiKey', 'none')
`rateLimit`	number	—	Maximum number of requests per minute allowed for this tool
`timeoutMs`	number	—	Request timeout in milliseconds (default: 30000)
`description`	string	—	Description of what the tool does and when the bot should use it

Parameters from the server's own tool schema.

RISK

Why neuron_create_tool is rated Medium

This tool creates a new resource (a custom API tool) within the platform, which is a reversible write operation. While it mentions triggering actions, the tool itself is about creating configuration, not executing those actions directly. The severity is medium because a misconfigured or malicious tool definition could cause the bot to invoke harmful external APIs during conversations.

From the tool's definition Create a custom API tool that the bot can invoke during conversations to fetch external data or trigger actions.

RECOMMENDED RULE

The rule that runs neuron_create_tool safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Neuron, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For neuron_create_tool, this is the rule to start with:

neuron_create_tool Rate-limited

neuron_create_tool stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "neuron_create_tool": {
      "limits": [
        {
          "counter": "neuron_create_tool_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Neuron, apply this rule, and every neuron_create_tool call is checked against it from then on.

FAQ

Questions about neuron_create_tool

What does the neuron_create_tool tool do? +

Create a custom API tool that the bot can invoke during conversations to fetch external data or trigger actions. It is categorised as a Write tool in the Neuron MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does neuron_create_tool accept? +

neuron_create_tool accepts 8 parameters: name, type, botId, config, authType, rateLimit, timeoutMs, description. Required: name, type, botId, config. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on neuron_create_tool? +

Register the Neuron MCP server in PolicyLayer and add a rule for neuron_create_tool: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Neuron. Nothing to install.

What risk level is neuron_create_tool? +

neuron_create_tool is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit neuron_create_tool? +

Yes. Add a rate_limit block to the neuron_create_tool rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block neuron_create_tool completely? +

Set action: deny in the PolicyLayer policy for neuron_create_tool. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides neuron_create_tool? +

neuron_create_tool is provided by the Neuron MCP server (neuron-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
