MOST DANGEROUS TOOLS

Critical Risk

The most dangerous MCP Mediawiki tools

Destructive · High delete_page_tool The tool irrevers ibly deletes wiki page con tent, wh ich canno t be undone . Write · Medium create_page_tool This tool creates new wiki pages, which is a reversible modification of data. Write · Medium edit_page_tool Editing a wiki page modifies content reversibly—changes can be undone through wiki history/reversion. Write · Medium move_page_tool Moving a page in MediaWiki changes its title and location but preserves content and history, making it reversible.

4 of MCP Mediawiki's 19 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 Mediawiki

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

Deny destructive operations

{
  "delete_page_tool": {
    "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_page_tool": {
    "limits": [
      {
        "counter": "create_page_tool_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_category_members_tool": {
    "limits": [
      {
        "counter": "get_category_members_tool_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 MCP Mediawiki — 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 MCP Mediawiki

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

Yes. The MCP Mediawiki server exposes 1 destructive tools including delete_page_tool. 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 Mediawiki? +

The MCP Mediawiki server has 3 write tools including create_page_tool, edit_page_tool, move_page_tool. 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 Mediawiki.

How many tools does the MCP Mediawiki MCP server expose? +

19 tools across 4 categories: Destructive, Execute, Read, Write. 15 are read-only. 4 can modify, create, or delete data.

How do I enforce a policy on MCP Mediawiki? +

Register the MCP Mediawiki 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 Mediawiki tool call.

Deterministic rules across all 19 MCP Mediawiki tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
