Label Management Implementation Summary

Overview

Successfully implemented comprehensive label management functionality for the Gogs MCP server, resolving issue #3.

Implementation Details

1. Core Client Methods (src/gogs-client.ts)

Added 10 new methods to the GogsClient class:

Repository Label Management

• listLabels(owner, repo): List all labels in a repository
• getLabel(owner, repo, labelId): Get a specific label by ID
• createLabel(owner, repo, {name, color}): Create a new label
• updateLabel(owner, repo, labelId, {name?, color?}): Update an existing label
• deleteLabel(owner, repo, labelId): Delete a label

Issue Label Management

• listIssueLabels(owner, repo, issueNumber): List labels on a specific issue
• addIssueLabels(owner, repo, issueNumber, labelIds[]): Add labels to an issue
• removeIssueLabel(owner, repo, issueNumber, labelId): Remove a specific label from an issue
• replaceIssueLabels(owner, repo, issueNumber, labelIds[]): Replace all labels on an issue
• removeAllIssueLabels(owner, repo, issueNumber): Remove all labels from an issue

2. MCP Server Integration (src/server.ts)

Schemas Added

• ListLabelsSchema
• GetLabelSchema
• CreateLabelSchema
• UpdateLabelSchema
• DeleteLabelSchema
• ListIssueLabelsSchema
• AddIssueLabelsSchema
• RemoveIssueLabelSchema
• ReplaceIssueLabelsSchema
• RemoveAllIssueLabelsSchema

MCP Tools Registered

All 10 label management operations are now available as MCP tools with proper:

• Input validation using Zod schemas
• Parameter descriptions
• Required/optional field specifications
• Error handling

3. Documentation Updates

README.md

• Added "Label Management" section to Features
• Documented all 10 label management tools
• Provided parameter descriptions and requirements
• Included examples of color format (#rrggbb)

USAGE_EXAMPLES.md

• Added comprehensive "Label Management" section
• Provided natural language usage examples for all operations
• Demonstrated both repository-level and issue-level label operations
• Included examples of adding, removing, and replacing labels

4. API Endpoints Implemented

Repository Labels

• GET /repos/:owner/:repo/labels - List all labels
• GET /repos/:owner/:repo/labels/:id - Get single label
• POST /repos/:owner/:repo/labels - Create label
• PATCH /repos/:owner/:repo/labels/:id - Update label
• DELETE /repos/:owner/:repo/labels/:id - Delete label

Issue Labels

• GET /repos/:owner/:repo/issues/:number/labels - List issue labels
• POST /repos/:owner/:repo/issues/:number/labels - Add labels to issue
• DELETE /repos/:owner/:repo/issues/:number/labels/:id - Remove label from issue
• PUT /repos/:owner/:repo/issues/:number/labels - Replace all issue labels
• DELETE /repos/:owner/:repo/issues/:number/labels - Remove all issue labels

Statistics

• Files Modified: 4
• Lines Added: 706
• New Methods: 10
• New MCP Tools: 10
• New Schemas: 10
• API Endpoints: 10

Testing

✅ TypeScript compilation successful ✅ All methods properly compiled to JavaScript ✅ Type definitions generated correctly ✅ No compilation errors ✅ All tools registered in MCP server

Usage Examples

Creating a Label

// Natural language with Claude
"Create a new label called 'bug' with red color (#ff0000) in owner/repo"

// Direct tool call
{
  "tool": "create_label",
  "arguments": {
    "owner": "owner",
    "repo": "repo",
    "name": "bug",
    "color": "#ff0000"
  }
}

Adding Labels to an Issue

// Natural language with Claude
"Add labels 3 and 5 to issue #7 in owner/repo"

// Direct tool call
{
  "tool": "add_issue_labels",
  "arguments": {
    "owner": "owner",
    "repo": "repo",
    "number": 7,
    "labels": [3, 5]
  }
}

Managing Issue Labels

// Replace all labels
"Replace all labels on issue #7 with labels 4 and 6"

// Remove all labels
"Remove all labels from issue #7 in owner/repo"

// Remove specific label
"Remove label ID 3 from issue #7 in owner/repo"

Design Decisions

1. Consistent Naming: All tools use snake_case naming convention (e.g., list_labels, add_issue_labels)
2. Type Safety: All methods use TypeScript types from types.ts (GogsLabel interface)
3. Error Handling: All API calls properly propagate errors to MCP error handling
4. Documentation: Comprehensive documentation for both users and developers
5. RESTful API: All methods follow Gogs API conventions and endpoints

Integration with Existing Features

The label management implementation integrates seamlessly with existing issue management:

• Labels can be assigned when creating issues (existing feature)
• Labels can be updated when modifying issues (existing feature)
• New dedicated label tools provide more granular control
• Label IDs are used consistently across all operations

Next Steps (Optional Enhancements)

Potential future improvements:

1. Add label color validation (ensure proper hex format)
2. Add bulk label operations
3. Add label search/filter functionality
4. Add label templates
5. Add label usage statistics

Conclusion

The label management feature is now fully implemented and ready for use. All 10 Gogs label API endpoints are available through the MCP server with comprehensive documentation and examples.
