PDF Agent StackBuilding a PDF-expert AI agent

Read, verify, write — grounded in the spec. Four MCP servers and three skills for AI agents.

pdf-spec-mcp (norm)

Specification reference over ISO 32000 and 16 more documents. Answers what the spec requires. Never opens the PDF under examination.

19 tools that observe what is inside a PDF — text, tables, structure tree, signature fields. Never passes judgment.

Cryptographic signature verification, tamper detection, PAdES level, PDF/A & PDF/UA validation, deterministic policy verdicts.

Creates PDFs from text / Markdown / tables and edits them with 20 tools. CJK font embedding built in.

Orchestrates trust audits of incoming PDFs. Returns a Trust Report with a four-value verdict.

Quality-gated delivery pipeline — write → read-back → verify, with a Publish Report.

Pulls what you need out of large or unreadable PDFs, and reports what could not be read.
