PDF MCP Server

# Troubleshooting (repo-local) ## Cursor MCP server didn’t pick up changes Symptom: you updated code/tests but Cursor still throws old errors. Fix: - restart Cursor, or - toggle the `pdf-handler` MCP server off/on ## Form filling issues Recommended verification: - write an output PDF - re-open with `pypdf.PdfReader` and inspect `get_fields()` and `/V` Hard requirement tools: - `fill_pdf_form` - `clear_pdf_form_fields` ## Signature + encryption workflow Use “sign then encrypt”: 1) `add_signature_image` (produces a new PDF) 2) `encrypt_pdf` on the signed output Verify: - `PdfReader(...).is_encrypted is True` - `decrypt(password)` returns 1 or 2 ## Where to find deeper SOPs (optional) If you have the Pepper memory bank repo on this machine, canonical docs include: - `pdf-handler-troubleshooting.md` - `mcp-index-and-selection-sop.md` - `release-sop-tag-based.md`
