WSL

[lmontanares]

Hello, I'm trying to make this MCP work on WSL. I already successfully made @executeautomation/playwright-mcp-server and @modelcontextprotocol/server-filesystem work.

Right now mcp-pandoc is kinda working, but I have 2 problems.

@lmontanares Were you able to find solution for this?

Error converting file from txt to docx: No pandoc was found: either install pandoc and add it
to your PATH or or call pypandoc.download_pandoc(...) or
install pypandoc wheels with included pandoc.

Looks like pandoc wasn't installed properly. Just in case, please recheck the required prerequisities in https://github.com/vivekVells/mcp-pandoc/tree/main?tab=readme-ov-file#critical-requirements

@vivekVells Yes! i instaled the requirements, changed the configuration and now it works fine, thanks!
