Search the knowledge base for relevant information.
AI agents call search_knowledge to retrieve information from Volcengine Knowledge Base MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from a knowledge base without creating, modifying, deleting, or executing arbitrary operations. It is a straightforward read operation that returns search results, making it the lowest risk category.
From the tool's definition Tool name 'search_knowledge' and description 'Search the knowledge base for relevant information' indicate a query operation with no data modification or side effects.
Attacks that exploit this kind of access
Search the knowledge base for relevant information. It is categorised as a Read tool in the Volcengine Knowledge Base MCP MCP Server, which means it retrieves data without modifying state.
Register the Volcengine Knowledge Base MCP server in PolicyLayer and add a rule for search_knowledge: 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 Volcengine Knowledge Base MCP. Nothing to install.
search_knowledge 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_knowledge 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_knowledge. 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_knowledge is provided by the Volcengine Knowledge Base MCP server (suqidan/volcengine_knowledgebase_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
