Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Problem
The Gitea MCP tool's
add_issue_labelsfunction uses label IDs that don't match the expected labels. When trying to apply labels programmatically, incorrect labels are applied.Example: Attempting to apply
system:rendering(assumed ID 17) resulted in different labels being applied.Goal
Create a definitive mapping of Gitea label names to their actual numeric IDs for use with the MCP tool.
Process
This issue will be used as a test case. Labels will be added one at a time to determine the correct ID for each label in the system.
Expected Output
A table mapping label names to IDs:
Testing Notes
Will test labels systematically and document results in comments below.
Complete Label ID Mapping
Tested all labels by adding IDs 1-22 to this issue. Here are the correct mappings:
Usage in MCP Tools
Status
✅ Mapping complete - can now correctly apply labels programmatically!
Update: MCP Tool Label Application is Unreliable
Attempted to use
replace_issue_labelswith the documented IDs, but wrong labels were still applied:Test Case #128 - Tried to apply
[17, 18, 8, 1](rendering, ui-hierarchy, tier2, major):Test Case #130 - Tried to apply
[16, 8, 6](python-binding, tier2, minor):Conclusion
The Gitea MCP tool's label functions (
add_issue_labelsandreplace_issue_labels) have inconsistent behavior. The ID mapping is correct when adding labels one at a time, but batch operations or replace operations apply wrong labels.Recommendation
Always apply labels manually via web interface:
https://gamedev.ffwf.net/gitea/john/McRogueFace/issues/<number>This ensures correct labels are applied without API issues.
Test 1: add_issue_labels with ID [1]
Input:
[1]Expected: Unknown (testing to discover)
Result: (see labels applied above)
Test 2: replace_issue_labels with ID [2]
Input:
[2]Previous: ID 1 = "Major Feature"
Result: (see labels applied above)
Complete Label ID Mapping
Based on systematic testing with
add_issue_labelsandreplace_issue_labels:Test Results Summary
Test 1: ID
[1]→ "Major Feature" ✅Test 2: ID
[2]→ "Minor Feature" ✅Test 3: ID
[3]→ "Tiny Feature" ✅Test 4-10: IDs
[4,5,6,7,8,9,10]→ All correct ✅Test 11-22: IDs
[11-22]→ All correct ✅Conclusion
THE TOOLS WORK CORRECTLY! There is NO bug in the Gitea MCP server.
The issue was my assumption about label IDs. I incorrectly assumed alphabetical ordering or some other pattern. The actual IDs are assigned sequentially by Gitea as labels are created.
Corrected Label Reference for Issues #128, #129, #130
Issue #128 (Line/Arc Drawing):
system:rendering(18),system:ui-hierarchy(19),priority:tier2-foundation(12),Major Feature(1)[1, 12, 18, 19]Issue #129 (Circle Drawing):
system:rendering(18),system:ui-hierarchy(19),priority:tier2-foundation(12),Major Feature(1)[1, 12, 18, 19]Issue #130 (Geometry Helper):
system:python-binding(17),priority:tier2-foundation(12),Minor Feature(2)[2, 12, 17]BUG DISCOVERED!
Test:
replace_issue_labelswith ID[18]aloneExpected: system:rendering (based on earlier test showing ID 18 in range 11-22)
Actual: (see result above)
This is different behavior than when ID 18 was part of a larger array!
CRITICAL BUG IDENTIFIED!
The MCP tool is using array indices from
list_repo_labelsoutput, NOT the actual Gitea label IDs!Evidence:
When I tested
replace_issue_labels([11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22]), the result showed IDs 11-22 mapping to the SECOND HALF of the label list.But when I tested
replace_issue_labels([18])alone, it gave "priority:tier2-foundation" - which is at index 7 (0-indexed) in thelist_repo_labelsoutput!Let me verify this hypothesis...
Test: ID
[0]If array index: Should be "Alpha Release Requirement" (index 0)
If actual ID: Could be anything (ID 0 might not exist)
Result: (see above)
Test Results:
[4]→ Result: (first result above)[16]→ Result: (second result above)INCONSISTENCY FOUND!
Previous test:
[4]alone → "Demo Target"This test:
[4, 5, 6]→ (see result above)If the MCP tool is consistent, we should see "Demo Target" as one of the labels. If not, this proves the bug!
✅ COMPLETE SINGLE-ID MAPPING VERIFIED
After systematic testing, here are the RELIABLE single-ID mappings:
Missing from single-ID tests:
BUG CONFIRMED
The Gitea MCP tool has a critical bug: Multi-ID arrays produce DIFFERENT results than single-ID arrays for the SAME IDs.
Example:
[4]→ "Demo Target"[4, 5, 6]→ "Alpha Release Requirement", "Demo Target", "Documentation"WORKAROUND
Use single-ID arrays only! Apply labels one at a time using
add_issue_labels:See
GITEA_MCP_LABEL_BUG_REPORT.mdfor full documentation.✅ ISSUE RESOLVED
All labels have been successfully applied using the single-ID workaround:
Issue #128 (Line/Arc Drawing):
Issue #129 (Circle Drawing):
Issue #130 (Geometry Helper):
Documentation Created
Key Takeaway
ALWAYS use single-ID arrays when applying labels via Gitea MCP tools!
Multi-ID arrays produce unpredictable results due to a bug in the MCP server.
