MOST DANGEROUS TOOLS

Critical Risk

The most dangerous MCP Memory LibSQL tools

Destructive · High delete_entity The tool permanently deletes entities and cascades the deletion to associated observations and relations. Destructive · High delete_relation This tool permanently removes relational data from the memory system. Write · Medium create_entities The tool creates new entities in the persistent memory system, which modifies data state reversibly. Write · Medium create_relations The tool creates or establishes new relationships between entities in the knowledge graph, which is a reversible modification of data.

4 of MCP Memory LibSQL's 6 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Memory LibSQL

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Memory LibSQL, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "delete_entity": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "create_entities": {
    "limits": [
      {
        "counter": "create_entities_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "read_graph": {
    "limits": [
      {
        "counter": "read_graph_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about MCP Memory LibSQL

Can an AI agent delete data through the MCP Memory LibSQL MCP server? +

Yes. The MCP Memory LibSQL server exposes 2 destructive tools including delete_entity, delete_relation. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through MCP Memory LibSQL? +

The MCP Memory LibSQL server has 2 write tools including create_entities, create_relations. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach MCP Memory LibSQL.

How many tools does the MCP Memory LibSQL MCP server expose? +

6 tools across 3 categories: Destructive, Read, Write. 2 are read-only. 4 can modify, create, or delete data.

How do I enforce a policy on MCP Memory LibSQL? +

Register the MCP Memory LibSQL MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every MCP Memory LibSQL tool call.

Deterministic rules across all 6 MCP Memory LibSQL tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
