AI agents use create_snippet_tool to create or update resources in MCP Gitlab — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Gitlab environment.

WHY IT NEEDS A POLICY

Why create_snippet_tool needs a policy

This tool creates snippets in GitLab, which is a reversible write operation. It modifies repository state by adding new content but does not delete or execute arbitrary code. Tool description is empty, which slightly lowers confidence, but the name and context of sibling tools provide strong evidence of write-class functionality.

From the tool's definition Tool name is 'create_snippet_tool' and sibling tools include create_* variants (create_branch_tool, create_file_tool, create_issue_tool, etc.) which are clearly write operations. The pattern of 'create_' prefix strongly indicates data creation.
