Search the hivemind knowledge base for troubleshooting solutions, error fixes, and best practices. Returns ranked solutions with success rates.
AI agents call search_kb to retrieve information from Hivemind MCP 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 data from a knowledge base without creating, modifying, deleting, or executing any operations. It has no side effects beyond returning search results. The low severity reflects that misuse would only expose or retrieve existing information from the knowledge base, posing minimal risk compared to write, execute, or destructive operations.
From the tool's definition Tool name 'search_kb' and description states it 'Search[es] the hivemind knowledge base' and 'Returns ranked solutions'. The verb 'search' and the behavior of querying and retrieving information without modification indicates a read-only operation.
Attacks that exploit this kind of access
Search the hivemind knowledge base for troubleshooting solutions, error fixes, and best practices. Returns ranked solutions with success rates. It is categorised as a Read tool in the Hivemind MCP MCP Server, which means it retrieves data without modifying state.
Register the Hivemind MCP server in PolicyLayer and add a rule for search_kb: 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 Hivemind MCP. Nothing to install.
search_kb 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 search_kb 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 search_kb. 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.
search_kb is provided by the Hivemind MCP server (kevthetech143/hivemind-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
