Where are Claude Desktop MCP server logs on Windows?

  This issue was closed as not planned; a maintainer asked for it to be re-posted in GitHub Discussions, so there is no official fix. The thread still gives two workarounds that worked for other users:

  1. Log location on Windows: a commenter confirmed the logs live in C:\Users\<YourUsername>\AppData\Roaming\Claude\logs, not the AppData\Local\Claude\Logs path you would guess from the Mac tutorial (~/Library/Logs/Claude/). The thread does not give exact filenames inside that folder, so list the directory and look for mcp*.log files (that last step is general advice).

  2. No log file is generated at all: another commenter found that when the MCP server name in the config contains a dash (for example mcp-server-filesystem), no mcp-server-SERVERNAME.log file is created. Renaming the server to a single word or camelCase (for example filesystem or filesystemServer) in the Claude Desktop config made the log file appear.

  Note: the PowerShell Get-Content ... -Wait -Tail 20 and Git Bash tail commands quoted in the issue body were only pasted as suggestions; the thread does not confirm that they were run or that they work.

  What a GitHub user tried on GitHub (Didn't work)

  The reporter followed the MCP servers tutorial troubleshooting and looked for mcp.log and mcp-server-SERVERNAME.log at C:\Users\YourUsername\AppData\Local\Claude\Logs\ (the path they were told was the Windows equivalent), but the files were not there.

  What @GersonGv tried on GitHub (Worked)

  A commenter reported that on Windows the logs are actually in AppData\Roaming\Claude\logs rather than the AppData\Local\Claude\Logs path suggested in the issue.

  What @alexitaccount4u tried on GitHub (Worked)

  A commenter found that a dash in the MCP server name prevented the log file from being generated. Renaming the server to a single word or camelCase (removing the dash) made the log appear.
