List all knowledge sources available in Dataverse.
AI agents call list_knowledge_sources to retrieve information from API Registry 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 enumerates metadata about knowledge sources without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal blast radius if misused by an AI agent—worst case being information disclosure about available sources.
From the tool's definition Tool name 'list_knowledge_sources' and description 'List all knowledge sources available in Dataverse' indicate a retrieval/query operation with no modification or execution of external operations.
Attacks that exploit this kind of access
List all knowledge sources available in Dataverse. It is categorised as a Read tool in the API Registry MCP Server MCP Server, which means it retrieves data without modifying state.
Register the API Registry MCP Server MCP server in PolicyLayer and add a rule for list_knowledge_sources: 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 API Registry MCP Server. Nothing to install.
list_knowledge_sources 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_knowledge_sources 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_knowledge_sources. 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_knowledge_sources is provided by the API Registry MCP Server MCP server (lucamilletti99/dataverse_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_knowledge_sources is one line of API Registry MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
