What create_wiki_page does on Gitlab Mcp
AI agents use create_wiki_page to create or update resources in Gitlab Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab Mcp environment.
Why create_wiki_page is rated Medium
This tool creates new wiki content, which is a reversible modification (wiki pages can be edited or deleted). It does not execute code, delete data permanently, or move funds, so it falls under Write rather than Execute, Destructive, or Financial.
From the tool's definition Tool name 'create_wiki_page' and description 'Create a wiki page in a project' indicate the tool creates new content in a project's wiki. The verb 'create' and 'wiki page' confirm this is a write operation that adds data reversibly.
Attacks that exploit this kind of access
The rule that runs create_wiki_page safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_wiki_page, this is the rule to start with:
create_wiki_page stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every create_wiki_page call is checked against it from then on.
