MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Collectives tools

Destructive · High delete_page Although the tool moves content to trash rather than permanently purging it, it is categorized as Destructive because it irreversibly removes pages from active use and can recursively delete entire page hierarchies (subt Destructive · High delete_attachment This tool permanently removes an attachment, which cannot be undone. Destructive · High delete_collective Although the deletion is soft (recoverable from trash), this tool irreversibly removes a Collective from normal access and operation. Destructive · High delete_tag This tool permanently removes a tag from a Collective, which cannot be undone.

26 of Collectives's 40 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Collectives

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

Deny destructive operations

{
  "delete_attachment": {
    "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

{
  "copy_page": {
    "limits": [
      {
        "counter": "copy_page_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_backlinks": {
    "limits": [
      {
        "counter": "get_backlinks_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register Collectives — nothing to install.
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 Collectives

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

Yes. The Collectives server exposes 7 destructive tools including delete_attachment, delete_collective, delete_page. 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 Collectives? +

The Collectives server has 19 write tools including copy_page, create_collective, create_page. 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 Collectives.

How many tools does the Collectives MCP server expose? +

40 tools across 3 categories: Destructive, Read, Write. 14 are read-only. 26 can modify, create, or delete data.

How do I enforce a policy on Collectives? +

Register the Collectives 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 Collectives tool call.

Deterministic rules across all 40 Collectives tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
