Generate embeddings for text using an Ollama model.
AI agents call ollama_embeddings 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 converts text into vector embeddings, which is a read/compute operation with no side effects. It does not modify data, execute commands, or interact with external systems beyond querying the local Ollama instance for a mathematical transformation of text. The output is a numerical representation used for downstream analysis.

Attacks that exploit this kind of access
Generate embeddings for text using an Ollama 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 ollama_embeddings: 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.
ollama_embeddings 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_embeddings 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_embeddings. 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_embeddings is provided by the Ollama MCP Server MCP server (ngc-shj/ollama-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
