List models
AI agents call ollama_list to retrieve information from Unified 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 straightforward listing/enumeration tool that returns metadata about local LLM models. It has no side effects, performs no code execution, creates no resources, and poses minimal risk if invoked by an AI agent. Classification as Read with low severity is appropriate.
From the tool's definition Tool name 'ollama_list' and description 'List models' indicate a query operation that retrieves information about available Ollama models without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
List models. It is categorised as a Read tool in the Unified MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unified MCP Server MCP server in PolicyLayer and add a rule for ollama_list: 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 Unified MCP Server. Nothing to install.
ollama_list 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 ollama_list 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 ollama_list. 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.
ollama_list is provided by the Unified MCP Server MCP server (qingyunyupan/ollama-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
