[BUG] Atlassian MCP updateConfluencePage hangs and fails with large content payloads

Environment

• Platform (select one):
• [ ] Anthropic API
• [x] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other:
• Claude CLI version: 1.0.18
• Operating System: macOS (Darwin 23.6.0)
• Terminal: iTerm2 3.5.14

Bug Description

The mcp__atlassian__updateConfluencePage tool hangs indefinitely and eventually fails with "API Error 1/10 ... 10/10" when attempting to update a Confluence page with large content payloads (~58,000 characters). The same operation works successfully with smaller content (first 33 lines, 3,268 characters).

Steps to Reproduce

1. Set up Atlassian MCP server integration with Claude Code (https://mcp.atlassian.com/v1/sse)
2. Attempt to use mcp__atlassian__updateConfluencePage with a large markdown content body (approximately 58,000 characters, 74 lines)
3. Observe the tool hanging for extended periods
4. Eventually receive "API Error 1/10 ... 10/10" failure messages
5. Retry the same operation with only the first 33 lines of content (3,268 characters) - this works successfully

Expected Behavior

• The tool should either successfully update the Confluence page regardless of content size (within reasonable limits)
• OR provide a clear error message indicating content size limitations
• OR fail quickly with a descriptive error rather than hanging

Actual Behavior

• Tool hangs for extended periods when processing large content
• Eventually fails with generic "API Error 1/10 ... 10/10" messages
• No clear indication of what the size limitation is or that size is the issue
• Smaller content works fine, suggesting an undocumented size threshold somewhere between 3,268 and 58,000 characters

Additional Context

• Issue appears to be related to content size rather than content type (markdown formatting)
• Current limitation: Only workaround is to use truncated content, which is inadequate when full page updates are required
• This suggests there may be an internal buffer limitation or timeout in the MCP integration
• The hanging behavior makes it difficult to quickly identify the root cause
• No clear documentation found regarding content size limits for this tool
• MCP server reference: https://mcp.atlassian.com/v1/sse
