Deterministic PDF tools for AI agents: inspect fields, fill forms, merge PDFs, invoices.
Security Report
A well-designed MCP server with proper authentication, no dangerous patterns, and permissions appropriately scoped to its PDF processing purpose. The architecture of using file paths rather than base64 blobs is a security strength. Minor code quality observations around error handling are present but do not materially affect security. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

}
}

pdfops-mcp
MCP server that gives AI agents deterministic PDF tools, backed by the PDFops API: inspect AcroForm fields, fill forms, merge PDFs, and generate invoices — no Chromium, no native deps, nothing to host.
Tools operate on local file paths, so PDF bytes never transit the model context: your agent says "fill /tmp/form.pdf and save to /tmp/out.pdf" and gets a one-line confirmation back.
Install
Claude Code
claude mcp add pdfops -- npx -y pdfops-mcp
Claude Desktop (claude_desktop_config.json) / Cursor (.cursor/mcp.json)
{
"mcpServers": {
"pdfops": {
"command": "npx",
"args": ["-y", "pdfops-mcp"],
"env": { "PDFOPS_API_KEY": "pdfops_live_…" }
}
}
}
PDFOPS_API_KEY is optional — without it you get the keyless trial (100 requests/IP/month). A free key (250/month, no card) takes one field at pdfops.dev/pricing.
Tools
| Tool | What it does |
|---|---|
pdf_inspect | List a PDF's form fields (names, types, options, values) + a paste-ready fill template. Call first on unfamiliar PDFs. |
pdf_fill | Fill AcroForm fields → write the filled PDF. Optional flatten bakes values in and drops the form. |
pdf_merge | Merge ≥2 PDFs in order → write the result. |
pdf_invoice | Structured data → complete invoice PDF. Deterministic: same input, byte-identical output. |
pdfops_usage | Quota check for the configured key. |
Example agent flow
"Fill the W-9 template at ~/docs/w9.pdf for Ada Lovelace and merge it with ~/docs/cover.pdf"
pdf_inspect→ discovers field names + fill templatepdf_fill→ writes the filled W-9pdf_merge→ writes the combined packet
