AI agents invoke parse-wikitext to trigger processes or run actions in MediaWiki MCP Server. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
parse-wikitext can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access parse-wikitext gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Renders wikitext through the live wiki without saving. Returns HTML, parse warnings, categories, wikilinks, templates, external URLs, and display title. Suited to dry-running a planned edit before create-page or update-page, or previewing standalone wikitext (template combinations, sanitizer checks) with no target page. HTML output is truncated at 50000 bytes with a trailing marker; a smaller wikitext fragment in a follow-up call returns the rest.. It is categorised as a Execute tool in the MediaWiki MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MediaWiki MCP Server MCP server in PolicyLayer and add a rule for parse-wikitext: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MediaWiki MCP Server. Nothing to install.
parse-wikitext is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the parse-wikitext rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for parse-wikitext. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
parse-wikitext is provided by the MediaWiki MCP Server MCP server (@professional-wiki/mediawiki-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
