Sporadic Timeouts (MCP error -32001) with SSE After Upgrading from 1.0.65 to 1.0.76+

[super-kishik]

Bug Description

Hello, I am encountering sporadic timeouts with gitlab-mcp.
This issue started immediately after upgrading the gitlab-mcp Docker image from version 1.0.65 to 1.0.76 I also tested version 2.0.2 and experienced the same problem.

The application experiences sporadic timeouts when executing tools. The error returned is MCP error -32001: Request timed out.

Error Logs:

Failed to execute tool "get_commit"
MCP error -32001: Request timed out
Failed to execute tool "list_commits"
MCP error -32001: Request timed out

Downgrading the image back to 1.0.65 resolves the issue completely, and the application functions as expected. My setup is running within Docker with SSE endpoint.

Steps to Reproduce

1. Configure and run the gitlab-mcp project using a Docker image with a version greater than 1.0.65 (e.g., 1.0.76 or 2.0.2).
2. Use the configuration provided below, with SSE enabled.
3. Make calls to the service that execute tools like list_commits or get_commit.
4. Observe the application over time. Sporadically, these tool executions will fail with a timeout error.

Configuration

Here is the relevant environment configuration for the Docker container:

- name: LOG_LEVEL
  value: debug
- name: GITLAB_API_URL
  value: https://gitlab.com/api/v4
- name: GITLAB_READ_ONLY_MODE
  value: "true"
- name: USE_PIPELINE
  value: "true"
- name: USE_MILESTONE
  value: "true"
- name: USE_GITLAB_WIKI
  value: "false"
- name: SSE
  value: "true"
- name: HOST
  value: 0.0.0.0
- name: PORT
  value: "9000"

Troubleshooting Steps Taken

• Enabled LOG_LEVEL: debug, but no specific errors or indicative logs were found related to the timeouts.

• Confirmed that downgrading to 1.0.65 is a reliable workaround.

Any guidance on how to further debug this would be greatly appreciated. Thank you.
