File not found error

[samhaaf]

Hi,

My agent is calling the tool with these args:

{
  "sources": [
    {
      "path": "FooBar.pdf"
    }
  ],
  "include_full_text": true,
  "include_metadata": true,
  "include_page_count": true
}

And getting this response:

{
  "results": [
    {
      "source": "FooBar.pdf",
      "success": false,
      "error": "MCP error -32600: File not found at 'FooBar.pdf'."
    }
  ]
}

And I can confirm that the PDF exists. If I run the server directly (without making a request), I don't get any errors:

(base) samhaaf@Sams-MacBook-Pro Ewing % npx @sylphlab/pdf-reader-mcp
[Filesystem MCP - pathUtils] Project Root determined from CWD: /Users/samhaaf/Documents/Ewing
[Filesystem MCP] Server running on stdio

I'm working in Cursor on a Mac Pro (apple silicon)

I had it try with different path variations, like absolute paths and './' prefixed paths, and all of those options failed. The former failed because absolute paths are not allowed, and the latter failed with the same "File not found" error.

Even if we provide a correct path which is not absolute path, we get this error: Please provide binary data as `Uint8Array`, rather than `Buffer`.

Like this issue #11

Hi @samhaaf and @itsvaibhav01,

Thanks for the detailed info!

Just to let you know — we’ve moved the PDF reader tool into our monorepo, and the @sylphlab/pdf-reader-mcp package is no longer maintained.

Please check out the new package here:
👉 https://github.com/sylphlab/MCP/tree/main/packages/pdf

We’re actively developing it there, and it includes improved handling for file resolution (including working with tools like Cursor). If you migrate to the new package, your issue should be resolved — and if not, feel free to open an issue there directly!

Thanks again, and appreciate your support.

Best,
Kyle

Can this be used from Claude Desktop on windows? It looks so promising, but I'm unable to get the correct path syntax. "mcpServers": {
