Feature Request: Add Git Tag creation support

[RyoyaOsaki]

Feature Request

Summary

Add support for creating and managing Git tags in Azure DevOps repositories.

Motivation

Currently, the MCP server provides tools for branches (repo_create_branch), pull requests (repo_create_pull_request), and commits (repo_search_commits), but there is no tool for creating Git tags.

Git tags are essential for:

• Marking release versions (e.g., v1.0.0)
• CI/CD pipelines that trigger on tag creation
• Tracking specific points in repository history

Proposed Solution

Add the following tools to the repositories domain:

1. repo_create_tag - Create a new Git tag

   • Parameters:
     • repositoryId (required): Repository ID
     • tagName (required): Name of the tag (e.g., v1.0.0)
     • objectId (required): Commit SHA to tag
     • message (optional): Annotated tag message

2. repo_list_tags - List tags in a repository (Related: Feature Request: List tags per repository #336)

   • Parameters:
     • repositoryId (required): Repository ID
     • filter (optional): Filter pattern

3. repo_delete_tag - Delete a tag

   • Parameters:
     • repositoryId (required): Repository ID
     • tagName (required): Name of the tag to delete

Azure DevOps API Reference

These operations can be implemented using the Refs - Update Refs API with refs/tags/ prefix.

Use Case

AI agents automating release workflows need the ability to create Git tags programmatically. For example:

• "Create a release for version 1.2.0" → Agent creates tag v1.2.0 on the current commit
• "Tag the current commit as hotfix-2024-01" → Agent creates the specified tag

Additional Context

This feature was requested by a Claude Code user who needed to automate release tagging workflows.

This is the first time we have seen this ask. It will not be a priority until we get some more requests. Moving this to a discussion to track accordingly and get more votes.
