THE RISK

Why ollama_generate_code needs a policy

This tool invokes a local LLM (Ollama) to generate code, which constitutes triggering an external operation whose effects depend on arguments. The generated code could contain arbitrary logic; misuse by an AI agent could produce malicious, insecure, or destructive code snippets.

From the tool's definition "Generate code using Ollama" and "writing new functions, classes, or code snippets" — delegates code generation to a local Ollama model and returns executable code artifacts

POLICY

How to control ollama_generate_code

PolicyLayer is an MCP gateway — it sits between your AI agents and Ollama MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ollama_generate_code:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ollama_generate_code": {
      "limits": [
        {
          "counter": "ollama_generate_code_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

ollama_generate_code stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Ollama MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about ollama_generate_code

What does the ollama_generate_code tool do? +

Generate code using Ollama. Use this for writing new functions, classes, or code snippets. Provide detailed requirements and context. It is categorised as a Execute tool in the Ollama MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on ollama_generate_code? +

Register the Ollama MCP Server MCP server in PolicyLayer and add a rule for ollama_generate_code: 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 Ollama MCP Server. Nothing to install.

What risk level is ollama_generate_code? +

ollama_generate_code is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit ollama_generate_code? +

Yes. Add a rate_limit block to the ollama_generate_code 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 ollama_generate_code completely? +

Set action: deny in the PolicyLayer policy for ollama_generate_code. 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 ollama_generate_code? +

ollama_generate_code is provided by the Ollama MCP Server MCP server (jadael/ollamaclaude). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Ollama MCP Server tool call.

Start from Ollama MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
