Generate basic PDF

Idempotent

Build multi-page PDFs from ordered content blocks such as headings, paragraphs, tables, images, charts, barcodes, and form fields. Supports PDF/A archival, encryption, watermarks, and print-ready output.

Instructions

Multi-page PDF composed from ordered blocks: heading, paragraph, list, table, image (JPEG/PNG), link, toc (printed table of contents), barcode, svg, formField, chart, pageBreak, spacer — every block kind the engine offers, each sharing its body with the dedicated tool (add_table, embed_image, add_barcode, add_form, add_chart). DEFAULT for any document; use the dedicated tools only for a standalone artefact, add_attachment for embedded files and add_international_text for non-Latin scripts. pdfA + embedFonts:true for a valid PDF/A-1b/2b/2u/3b claim; outline / pageLabels / viewerPreferences / watermark for navigation and presentation; print, metadata, outputIntent, creationDate as on every document tool. The 'chart' block takes the same body as add_chart.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pdfANoPDF/A level: pdfa1b (simple text+images), pdfa2b/pdfa2u (richer; 2u = Unicode mapping), pdfa3b (attachments / Factur-X). Pair with embedFonts=true for a valid claim. Exclusive with encryption. See docs/guides/PDFA.md.
debugNoDraw margin / block / cell guide rectangles (unmarked content — not for PDF/UA output). Geometry unchanged. Default false.
printNoPrint production (ISO 32000-1 §14.11): page boxes, `bleed` shorthand (TrimBox = MediaBox inset), crop/registration marks outside the TrimBox, /UserUnit for large formats (PDF 1.7; not under pdfa1b). See docs/guides/PRINT.md.
titleYesDocument title (rendered at top of page 1 and used as PDF metadata title).
blocksYesOrdered list of content blocks composing the document body.
strictNoFail with PDF_A_COMPLIANCE_VIOLATION instead of producing a non-conformant PDF/A file (e.g. PDFA_NO_FONT_ENTRIES without embedFonts). Pair with embedFonts=true.
encryptNoEncrypt at build time (AES-128 default / AES-256) and KEEP the AcroForm — unlike encrypt_pdf, which rebuilds the page tree. Exclusive with pdfA. Randomised output, never cached.
marginsNoMargins in points, all four required (0–200). Default 45 / 36 / 35 / 36.
outlineNoDocument outline (bookmarks panel). Either 'auto' (derive a flat outline from heading blocks) or an explicit nested bookmark tree.
compressNoFlateDecode the streams (smaller file, different bytes; PDF/A unaffected, XMP stays plain). Default false.
metadataNo/Info (+ XMP under PDF/A): author, subject, keywords, /Trapped.
pageSizeNoPortrait page preset (points): A4 595.28×841.89 (default), Letter 612×792, Legal 612×1008, A3 841.89×1190.55, Tabloid 792×1224. print.* boxes must fit it.
normalizeNoUnicode normalization before shaping ('NFC' recommended for glyph coverage; NFD/NFKC/NFKD accepted). Omit = none.
watermarkNoOptional semi-transparent watermark rendered centred on every page: `text` (e.g. 'DRAFT'), `image` (JPEG/PNG), or both combined. At least one of text / image is required. opacity < 1.0 (text or image, including the defaults) is rejected under pdfA='pdfa1b' (ISO 19005-1 forbids transparency).
embedFontsNoEmbed Noto Sans Latin instead of the viewer base-14 Helvetica. REQUIRED for a valid PDF/A claim (ISO 19005 §6.2.11.4.1) and for strict=true; adds ~0.3 MiB.
footerTextNoOptional footer text rendered at the bottom of every page.
outputModeNoEither 'base64' (returns the PDF inline as a base64 string) or 'file' (writes to a path inside the configured PDFNATIVE_MCP_OUTPUT_DIR sandbox).base64
outputPathNoRequired when outputMode='file'. Relative path inside the sandbox; must end with .pdf.
pageLabelsNoPage-label ranges (the visible page numbers in the viewer, e.g. roman front-matter then decimal body). startPage values must be unique and strictly increasing.
creationDateNoISO-8601 instant for /CreationDate (+ XMP). Pin it for byte-identical output across calls (same host TZ); omitted = wall clock, so every call differs.
outputIntentNoCustom PDF/A OutputIntent: an RGB ICC profile + condition strings replacing the built-in sRGB intent (CMYK rejected).
footerTemplateNoRunning footer on every page. Replaces the default footer: footerText is then ignored and page numbers appear only via {page}/{pages}.
headerTemplateNoRunning header on every page (left / center / right zones); reserves 15 pt.
viewerPreferencesNoReader presentation hints (catalog /PageLayout, /PageMode, /ViewerPreferences). PDF/A-safe; all optional.
includeDiagnosticsNoReturn the PDF/A diagnostics raised while building as `diagnostics[]` (possibly empty).

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare idempotentHint=true and destructiveHint=false, lowering the behavioral burden, and the description contradicts none of them. It adds meaningful context beyond the schema: every block shares its body with the dedicated sibling tool, pdfA requires embedFonts for a valid claim, and optional groups such as outline/pageLabels/viewerPreferences/watermark are folded into functional categories. It does not describe error/edge behavior, but the 100% output schema and annotations cover enough.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense paragraph with no filler; the core purpose and routing are front-loaded and the rest is a compact feature-group summary. The block enumeration makes it long, but every sentence earns its place, so it is tight rather than padded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a high-complexity tool (25 parameters, deeply nested blocks, output schema present), and the description correctly delegates parameter detail to the schema while carrying what the schema cannot: the routing to siblings and the body-parity with dedicated tools. Minor non-obvious interplay such as a printed TOC depending on heading blocks is left to the schema, an acceptable and small gap for such a large surface.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the input schema itself describes every one of the 25 parameters with defaults, exclusivities and constraints, so the baseline of 3 applies. The description adds only cheap cross-block glue (body parity with dedicated tools, functional groups), which is useful but not required for parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with 'Multi-page PDF composed from ordered blocks' - a specific verb and resource plus the construction principle - and enumerates every block kind the engine offers. It also declares itself the 'DEFAULT' for any document, which clearly separates it from the block-specific sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit selection rule: 'DEFAULT for any document; use the dedicated tools only for a standalone artefact, add_attachment for embedded files and add_international_text for non-Latin scripts.' It names the exact alternatives and the conditions that call for them, so the routing is never left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
