AI agents call kobold_detokenize to retrieve information from Kobold MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that converts token identifiers into their text representation. It queries or transforms existing data without creating, modifying, deleting, or executing anything. No external operations are triggered and results are deterministic based on input tokens. Blast radius is minimal—misuse would only produce incorrect text output without affecting system state.
From the tool's definition Tool name 'kobold_detokenize' and description 'Convert token IDs to text' indicate a pure data transformation function that retrieves/decodes information without side effects.
Documented attack patterns abuse exactly the kind of access kobold_detokenize 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_detokenize:
{
"version": "1",
"default": "deny",
"tools": {
"kobold_detokenize": {}
}
}kobold_detokenize is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Convert token IDs to text. It is categorised as a Read tool in the Kobold MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kobold MCP Server MCP server in PolicyLayer and add a rule for kobold_detokenize: 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_detokenize is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the kobold_detokenize 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_detokenize. 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_detokenize 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.
