annotate_pdf

MCP tool from Pdfnative MCP by Nizoka

Overlay markup annotations on an existing PDF via incremental update. This is a visual review layer, not a redaction — the underlying content is untouched.

How to use it

Project documentation lists annotate_pdf for the Pdfnative MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

draft_governance_issue

Draft a governance-compliant GitHub issue locally for a human to review and submit. The server never contacts GitHub (its only possible egress is the operator-configured TSA / OCSP / CRL endpoints — see Network & egress); it returns the draft Markdown plus a machine-readable compliance report.

embed_image

generate_basic_pdf

inspect_layout

Read-only pagination dry run — the same blocks as generatebasicpdf plus every input that moves a block (title, footerText, pdfA, normalize, embedFonts, pageSize, margins, headerTemplate, footerTemplate). No PDF is produced; pass exactly what you will give generatebasicpdf and totalPages matches.

Read-only structural and security inspection — useful for downstream verification, CI assertions, and AI agents that need to reason about a PDF before acting on it.

sign_pdf

As of v1.0.0, signpdf auto-injects a /Sig placeholder when missing — you can sign any PDF in one call:

validate_pdf

Read-only PDF/UA (ISO 14289-1) structural conformance check for a Tagged PDF. Generate an accessible document with any tool using pdfA (e.g. pdfA: 'pdfa2u'), then validate the result:
