Add table / report

add_table

Idempotent

Generate a tabular PDF report from headers and rows, with smart layout controls for wrapping, repeated headers, zebra stripes, cell borders, and PDF/A compliance.

Instructions

Tabular PDF report from headers + rows (every row the same length). Smart-table options: wrap, repeatHeader (header on every page), zebra, caption (tagged for PDF/A), minRowHeight, cellPadding, cellBorders, cellVAlign, autoFitColumns, clipCells. Inside a longer document use a 'table' block of generate_basic_pdf instead. PDF/A (pdfA + embedFonts:true), print, metadata, watermark and creationDate options as on every document tool.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`pdfA`	No	PDF/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.
`rows`	Yes	Data rows. Each row is an array of cell strings with the same length as `headers`.
`wrap`	No	Cell wrap policy: 'auto' (default) wraps only overflowing cells; 'always' wraps every cell; 'never' truncates.
`debug`	No	Draw margin / block / cell guide rectangles (unmarked content — not for PDF/UA output). Geometry unchanged. Default false.
`print`	No	Print 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.
`title`	Yes	Report title rendered at the top of the document and used as PDF metadata title.
`zebra`	No	Alternate-row light tint (static fill, PDF/A-1b safe).
`strict`	No	Fail 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.
`caption`	No	Caption rendered above the table (tagged as /Caption under PDF/A).
`encrypt`	No	Encrypt 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.
`headers`	Yes	Column header labels. Must have the same length as each row in `rows`.
`margins`	No	Margins in points, all four required (0–200). Default 45 / 36 / 35 / 36.
`compress`	No	FlateDecode the streams (smaller file, different bytes; PDF/A unaffected, XMP stays plain). Default false.
`metadata`	No	/Info (+ XMP under PDF/A): author, subject, keywords, /Trapped.
`pageSize`	No	Portrait 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.
`clipCells`	No	Clip cell contents to the column bounds (PDF clip operators). Recommended for PDF/A and visual safety.
`infoItems`	No	Optional key-value metadata rows rendered below the title (e.g. date, author).
`watermark`	No	Optional 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).
`cellVAlign`	No	Vertical alignment of cell content.
`embedFonts`	No	Embed 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.
`footerText`	No	Optional text rendered at the bottom of every page.
`outputMode`	No	Either 'base64' (returns the PDF inline) or 'file' (writes to a sandboxed path inside PDFNATIVE_MCP_OUTPUT_DIR).	base64
`outputPath`	No	Required when outputMode='file'. Relative path inside the sandbox; must end with .pdf.
`cellBorders`	No	Per-cell vector borders (pure strokes, PDF/A-safe). Choose individual sides or `all`.
`cellPadding`	No	Horizontal cell padding in points (default 3).
`creationDate`	No	ISO-8601 instant for /CreationDate (+ XMP). Pin it for byte-identical output across calls (same host TZ); omitted = wall clock, so every call differs.
`minRowHeight`	No	Minimum row height in points (default 12).
`outputIntent`	No	Custom PDF/A OutputIntent: an RGB ICC profile + condition strings replacing the built-in sRGB intent (CMYK rejected).
`repeatHeader`	No	Repeat the header row on every continuation page (default true).
`autoFitColumns`	No	Auto-fit column widths to content. Output bytes then depend on text metrics (not byte-deterministic across content changes).
`footerTemplate`	No	Running footer on every page. Replaces the default footer: footerText is then ignored and page numbers appear only via {page}/{pages}.
`headerTemplate`	No	Running header on every page (left / center / right zones); reserves 15 pt.
`viewerPreferences`	No	Reader presentation hints (catalog /PageLayout, /PageMode, /ViewerPreferences). PDF/A-safe; all optional.
`includeDiagnostics`	No	Return the PDF/A diagnostics raised while building as `diagnostics[]` (possibly empty).

Output Schema

TableJSON Schema

Name	Required	Description
`mode`	Yes
`summary`	No	Tool-specific summary, when produced.
`filePath`	No	Sandboxed absolute path (file mode).
`sizeBytes`	Yes
`diagnostics`	No	PDF/A diagnostics (when includeDiagnostics=true).

TDQS

A4.4/5.0

Behavior4/5

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

Annotations declare destructiveHint=false, readOnlyHint=false, idempotentHint=true. The description adds meaningful behavior: PDF/A interaction with embedFonts, strict failure mode (PDF_A_COMPLIANCE_VIOLATION), tagged caption implications, and encryption/caching notes. These details exceed what annotations cover, though with a 34-param schema, the focus stays on the table-specific aspects.

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

Conciseness5/5

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

The description is dense and well-structured, front-loads the core concept (tabular PDF report from headers+rows), and packs the smart-table options into one efficient list. Every sentence adds value, with the routing to generate_basic_pdf placed last as a natural afterthought.

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?

The tool has a huge schema (34 params) and output schema, so the description does not need to explain every return value. It covers the key behavioral notes (PDF/A compliance, embedFonts), and the self-contained table nature is clear. It does not explicitly mention outputMode/outputPath, but the schema covers that, so the balance is appropriate.

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%, so the baseline is 3; the description does not need to restate every parameter. It adds a top-level framing ('Smart-table options: wrap, repeatHeader ...') that summarizes the parameter groups without duplicating schema detail. It directly compensates where the schema is otherwise terse, e.g., grouping the table-format options.

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?

The description opens with 'Tabular PDF report from `headers` + `rows` (every row the same length)', which names the specific verb (add/generate), the resource (table report), and the core inputs. It distinguishes this tool from generate_basic_pdf explicitly by mentioning the alternative for embedding a table inside a longer document.

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?

The description explicitly says 'Inside a longer document use a \'table\' block of generate_basic_pdf instead,' providing an exclusion condition and the named alternative. It also notes the shared options ('as on every document tool'), which sets expectations for typical usage.

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