set-wiki

Set the wiki to use for the current session.

Part of the Mediawiki MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use set-wiki to create or modify resources in Mediawiki. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON SET-WIKI

Without a policy, an AI agent could call set-wiki repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mediawiki.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the set-wiki tool do? +

Set the wiki to use for the current session.. It is categorised as a Write tool in the Mediawiki MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set-wiki? +

Add a rule in your Intercept YAML policy under the tools section for set-wiki. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mediawiki MCP server.

What risk level is set-wiki? +

set-wiki is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set-wiki? +

Yes. Add a rate_limit block to the set-wiki rule in your Intercept 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.

How do I block set-wiki completely? +

Set action: deny in the Intercept policy for set-wiki. 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.

What MCP server provides set-wiki? +

set-wiki is provided by the Mediawiki MCP server (yuhuison/mediawiki). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
