Get detailed information about a knowledge base via Open WebUI API
AI agents call get_knowledge_base_info to retrieve information from Open Webui Knowledge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries information about knowledge bases with no side effects. It falls squarely into the Read category as it accesses and returns data without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an agent could only learn unwanted details about available knowledge bases.
From the tool's definition Tool name 'get_knowledge_base_info' and description 'Get detailed information about a knowledge base via Open WebUI API' indicate retrieval of metadata without modification or execution.

PolicyLayer is an MCP gateway — it sits between your AI agents and Open Webui Knowledge, and nothing reaches the server without passing your rules. This is the rule we recommend for get_knowledge_base_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_knowledge_base_info": {}
}
}get_knowledge_base_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a knowledge base via Open WebUI API. It is categorised as a Read tool in the Open Webui Knowledge MCP Server, which means it retrieves data without modifying state.
Register the Open Webui Knowledge MCP server in PolicyLayer and add a rule for get_knowledge_base_info: 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 Open Webui Knowledge. Nothing to install.
get_knowledge_base_info 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 get_knowledge_base_info 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 get_knowledge_base_info. 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.
get_knowledge_base_info is provided by the Open Webui Knowledge MCP server (ronasit/open-webui-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Open Webui Knowledge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
