About pdfnative MCP — PDF/A & PDF/X-4 generation, PAdES signing & introspection

pdfnative MCP — PDF/A & PDF/X-4 generation, PAdES signing & introspection is an MCP server published by the GitHub account Nizoka. PDF MCP: generate PDF/A & PDF/X-4, sign & verify PAdES (LTV), forms, merge, split, encrypt. 28 tools

It runs on your own machine: your AI client starts it from the npm package pdfnative-mcp at version 1.7.0.

It asks for 2 secrets: PDFNATIVE_MCP_HTTP_TOKEN and PDFNATIVE_MCP_TSA_AUTH. Give it a key with the least access that still works.

Version 1.7.0 was published on 24 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.

What it asks for

VariableRequiredSecretDescription
PDFNATIVE_MCP_OUTPUT_DIRNoNoAbsolute path of a sandboxed directory where outputMode='file' may write PDFs. Unset: every tool returns base64 only (file output disabled).
PDFNATIVE_MCP_CACHE_DIRNoNoOpt-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_PORTNoNoServe 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_TOKENNoYesOpt-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_BYTESNoNoPer-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_CREATION_DATENoNoISO 8601 instant with a time zone (e.g. 2026-01-01T00:00:00Z) pinned as the creation date of every generated document: reproducible bytes on any host. A call's own creationDate still wins. An invalid value refuses to start the server.
SOURCE_DATE_EPOCHNoNoreproducible-builds.org convention: integer seconds since the Unix epoch, used as the pinned creation date when PDFNATIVE_MCP_CREATION_DATE is unset. An invalid value refuses to start the server.
PDFNATIVE_MCP_TSA_URLNoNohttp(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_AUTHNoYesOptional Authorization header value sent to the TSA (e.g. 'Basic ...' or 'Bearer ...'). Never logged or echoed.
PDFNATIVE_MCP_REVOCATIONNoNo'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_HOSTSNoNoComma-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_MSNoNoPer-request timeout for TSA / OCSP / CRL calls in milliseconds, 1000-120000 (default 10000).
