list_models
AI agents call list_models to retrieve information from Ollama_MCP_Guidance without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
list_models retrieves a list of available models from Ollama without modifying, executing against external systems, or deleting data. This is consistent with Read category operations like list and fetch. Severity is low because listing models has no side effects and limited blast radius if misused—at worst it provides information about what models are available.
From the tool's definition Tool name 'list_models' combined with sibling tools like 'get_ollama_list', 'get_running_models', and 'get_version' indicates this is a retrieval/query operation.
Attacks that exploit this kind of access
list_models. It is categorised as a Read tool in the Ollama_MCP_Guidance MCP Server, which means it retrieves data without modifying state.
Register the Ollama_MCP_Guidance MCP server in PolicyLayer and add a rule for list_models: 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_Guidance. Nothing to install.
list_models 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 list_models 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 list_models. 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.
list_models is provided by the Ollama_MCP_Guidance MCP server (shadovvsinger/ollama_mcp_guidance). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
