AI agents invoke kobold_generate to trigger actions in Kobold MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes a text generation process on the KoboldAI backend. It is not a simple read (it triggers computation and external model inference), not destructive, not financial, and not a write in the traditional sense. The closest category is Execute, as it runs an external operation whose output depends on the input arguments.
From the tool's definition "Generate text with KoboldAI" — triggers an external text generation operation via KoboldAI's engine
Documented attack patterns abuse exactly the kind of access kobold_generate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kobold MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for kobold_generate:
{
"version": "1",
"default": "deny",
"tools": {
"kobold_generate": {
"limits": [
{
"counter": "kobold_generate_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}kobold_generate 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.
Free to start. No card required.
Generate text with KoboldAI. It is categorised as a Execute tool in the Kobold MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Kobold MCP Server MCP server in PolicyLayer and add a rule for kobold_generate: 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 Kobold MCP Server. Nothing to install.
kobold_generate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the kobold_generate 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.
Set action: deny in the PolicyLayer policy for kobold_generate. 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.
kobold_generate is provided by the Kobold MCP Server MCP server (phialsbasement/koboldcpp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kobold MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
