AI agents call show to retrieve information from Ollama MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about a model—a read-only operation with no side effects. It poses minimal risk as it cannot modify, delete, or execute code. The blast radius of misuse is limited to potential information disclosure about available models.
From the tool's definition Tool name 'show' combined with description 'Show information for a model' indicates a retrieval operation that displays model metadata or properties without modification.
Documented attack patterns abuse exactly the kind of access show gives an agent:
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 show:
{
"version": "1",
"default": "deny",
"tools": {
"show": {}
}
}show is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show information for a model. It is categorised as a Read tool in the Ollama MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ollama MCP Server MCP server in PolicyLayer and add a rule for show: 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.
show 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 show 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 show. 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.
show is provided by the Ollama MCP Server MCP server (nighttrek/ollama-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
