WHAT IT DOES

What search_open_knowledge does on Delx MCP Server

Parameter	Type	Required	Description
`query`	string	Yes	Knowledge query, 1-120 characters.
`timeout`	integer	—	Upstream timeout in seconds.
`max_records`	integer	—	Maximum number of Wikipedia results.

Parameters from the server's own tool schema.

RISK

Why search_open_knowledge is rated Low

This is a constrained read operation querying public Wikipedia metadata via Wikimedia API. The tool retrieves and presents information without creating, modifying, deleting, or executing code. The bounded scope (English Wikipedia metadata only) and explicit limitations further reduce risk profile to low severity.

From the tool's definition Search functionality returning "page links and short snippets" with no modification capability. Description explicitly states "no general web search, article body, or arbitrary URL fetch", confirming retrieval-only semantics.

RECOMMENDED RULE

The rule that runs search_open_knowledge safely

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

search_open_knowledge Allowed

search_open_knowledge 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_open_knowledge": {}
  }
}

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

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