pdfnative MCP — PDF generation, PAdES signing & introspection

io.github.Nizoka/pdfnative-mcpv1.6.0Documents & Spreadsheets

PDF MCP server: generate PDF/A, sign & verify PAdES (LTV), forms, merge, split, encrypt. 28 tools

The current version, v1.6.0, was published to the official MCP registry on 2026-08-23. It is distributed as pdfnative-mcp on npm, filed under Documents & Spreadsheets by this index, and declares 10 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

Using pdfnative MCP — PDF generation, PAdES signing & introspection in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b
- Still current: the description we screened is unchanged, re-checked against the registry

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-09-22).

Contracts can change after screening, with no version bump. The gate pins pdfnative MCP — PDF generation, PAdES signing & introspection’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

PDFNATIVE_MCP_OUTPUT_DIR

Absolute path of a sandboxed directory where outputMode='file' may write PDFs. Unset: every tool returns base64 only (file output disabled).

PDFNATIVE_MCP_CACHE_DIR

Opt-in content-addressed response cache directory (SHA-256 keyed, 1h TTL, 256 MiB LRU, plaintext at rest). Never caches encrypt/decrypt, sign, timestamp, add_ltv, update_metadata, encrypted builds or file output.

PDFNATIVE_MCP_PORT

Serve Streamable HTTP on this loopback port instead of stdio (MCP 2026-07-28, stateless). Unauthenticated unless PDFNATIVE_MCP_HTTP_TOKEN is set.

PDFNATIVE_MCP_HTTP_TOKEN

secret

Opt-in bearer token for the HTTP transport (>= 16 chars, no whitespace). When set, /mcp requires 'Authorization: Bearer <token>' or answers 401. Never logged.

PDFNATIVE_MCP_MAX_INFLATE_BYTES

Per-stream FlateDecode decompression cap in bytes (zip-bomb mitigation; default 104857600 = 100 MiB). Integer >= 1024; an invalid value refuses to start the server.

PDFNATIVE_MCP_TSA_URL

http(s) URL of the RFC 3161 timestamp authority used by sign_pdf timestamp=true and timestamp_pdf (PAdES B-T / B-LTA). Unset: those calls fail with TSA_NOT_CONFIGURED and no network request is made. Tool arguments can never supply a URL.

PDFNATIVE_MCP_TSA_AUTH

secret

Optional Authorization header value sent to the TSA (e.g. 'Basic ...' or 'Bearer ...'). Never logged or echoed.

PDFNATIVE_MCP_REVOCATION

'ocsp', 'crl' or 'ocsp,crl': enables online revocation collection for add_ltv mode='online' (PAdES B-LT). Unset: that mode fails with REVOCATION_NOT_CONFIGURED; mode='offline' stays fully offline. Requires PDFNATIVE_MCP_NETWORK_ALLOWED_HOSTS.

PDFNATIVE_MCP_NETWORK_ALLOWED_HOSTS

Comma-separated allow-list of OCSP / CRL responder hosts ('host', 'host:port' or '*.suffix'). Mandatory when PDFNATIVE_MCP_REVOCATION is set: responder URLs found in certificates are fetched only if the host matches (http(s) only, no credentials, no redirects, internal addresses rejected unless listed verbatim).

PDFNATIVE_MCP_NETWORK_TIMEOUT_MS

Per-request timeout for TSA / OCSP / CRL calls in milliseconds, 1000-120000 (default 10000).

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 968,092). Verify it yourself.
