WHAT IT DOES

What search_kb does on FeatureBoard

AI agents call search_kb to retrieve information from FeatureBoard without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_kb is rated Low

This tool performs a search operation, which is a read-only retrieval action. It does not create, modify, delete, or execute operations—it merely queries and returns results from the knowledge base. Low severity because search operations have minimal blast radius and no side effects.

From the tool's definition Tool name 'search_kb' and description 'Keyword search across a board' indicate querying/searching functionality with no modification of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_kb safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FeatureBoard, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_kb, this is the rule to start with:

search_kb Allowed

search_kb is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_kb": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect FeatureBoard, apply this rule, and every search_kb call is checked against it from then on.
