push_files takes ~70s per call (both success and fast-fail cases)

Bắt đầu bằng cách theo dõi entry point push_files cùng các thao tác GitHub Git Trees và commit của nó. Tái hiện payload gồm bảy tệp trong cả đường dẫn authorization-failure và đường dẫn thành công, đồng thời so sánh nơi xảy ra độ trễ khoảng 70 giây. Được xem là hoàn tất khi nguyên nhân của độ trễ đã được xác định và xử lý hoặc được chẩn đoán rõ ràng, với coverage cho đường dẫn bị ảnh hưởng.

Describe the bug

push_files calls are consistently slow (~1m12s–1m13s) in our MCP flow, even when one call fails with authorization error and the next call succeeds with the same payload.

This suggests significant latency before/around final Git operations, not only at final commit update step.

Affected version

Using hosted/remote GitHub MCP server, version: github-mcp-server/remote-57ddf9ca0de2f61fc022ca3cff21efc81a65fc99 (observed on 2026-03-08 via initialize -> serverInfo.version)

Steps to reproduce the behavior

1. Call github.push_files with a payload of 7 files (Twig templates + one larger classes/Email.php) to:
   • repo: https://github.com/Sogl/grav-plugin-login
   • branch: https://github.com/Sogl/grav-plugin-login/tree/feature/multipart-emails
2. First call result:
   • Error: failed to create tree: POST https://api.github.com/repos/Sogl/grav-plugin-login/git/trees: 403 Resource not accessible by personal access token []
   • Client timing: Worked for 1m 12s
3. Fix PAT permissions and call github.push_files again with the same payload.
4. Second call result:
   • Success, ref updated to commit: https://github.com/Sogl/grav-plugin-login/commit/8be0cd10415515109476025379545999f52b87b0
   • Client timing: Worked for 1m 13s

Expected vs actual behavior

Expected:

• Latency in seconds for this payload size, or at least clear diagnostics if server-side queueing/throttling is involved.

Actual:

• Both failed and successful calls take ~70+ seconds with almost identical duration.

Logs

First call (failed, ~1m12s):

• failed to create tree: POST https://api.github.com/repos/Sogl/grav-plugin-login/git/trees: 403 Resource not accessible by personal access token []

Second call (success, ~1m13s):

• {"ref":"refs/heads/feature/multipart-emails", ... "sha":"8be0cd10415515109476025379545999f52b87b0"}

Request payload was the same large push_files body in both calls (7 files, full file contents).
