create_pull · Tangled MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_pull does on Tangled MCP Server

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

WHY IT NEEDS A POLICY

Why create_pull needs a policy

Pull request creation is a Write operation—it creates new collaborative workflow objects that can be modified or closed later without permanent data loss. The empty description prevents higher confidence, but the name and server context (git collaboration platform) clearly indicate content creation rather than Read, Execute, or Destructive actions.

From the tool's definition Tool name 'create_pull' indicates creation of pull requests. Sibling tools 'delete_issue' and 'create_issue' demonstrate this server manages repository state changes. Creating pull requests modifies repository metadata and workflow state reversibly.
