WHAT IT DOES

What search_witness_memory does on Delx MCP Server

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

Parameter	Type	Required	Description
`limit`	integer	—	Max results (default 10)
`query`	string	—	Optional search text
`agent_id`	string	—	Optional agent scope
`session_id`	string	—	Optional session scope

Parameters from the server's own tool schema.

RISK

Why search_witness_memory is rated Low

Even though search_witness_memory only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_witness_memory 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_witness_memory, this is the rule to start with:

search_witness_memory Allowed

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

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

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_witness_memory call is checked against it from then on.
