AI agents call full_text_search to retrieve information from Mcp Oceanbase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Full-text search queries and retrieves data without modifying, deleting, or executing arbitrary code. Despite the empty description, the function name clearly indicates a read-only search capability. The low severity reflects that search operations have minimal blast radius—they access existing data but cannot alter system state or trigger unintended modifications.
From the tool's definition Tool name is 'full_text_search' which performs text search operations. The empty description limits certainty, but full-text search is fundamentally a retrieval operation with no documented side effects.
Documented attack patterns abuse exactly the kind of access full_text_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Oceanbase, and nothing reaches the server without passing your rules. This is the rule we recommend for full_text_search:
{
"version": "1",
"default": "deny",
"tools": {
"full_text_search": {}
}
}full_text_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

full_text_search. It is categorised as a Read tool in the Mcp Oceanbase MCP Server, which means it retrieves data without modifying state.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for full_text_search: 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 Mcp Oceanbase. Nothing to install.
full_text_search 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 full_text_search 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 full_text_search. 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.
full_text_search is provided by the Mcp Oceanbase MCP server (oceanbase/awesome-oceanbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
