The Iteration Layer API includes a built-in Model Context Protocol (MCP) server. MCP lets AI agents like Claude Desktop, Cursor, and Windsurf call the API directly as tools — no custom integration code required.

Server Endpoint

The MCP server is available via Streamable HTTP transport:

https://api.iterationlayer.com/mcp

Authentication

The MCP endpoint uses OAuth 2.1 — not API keys. Your MCP client handles the authentication flow automatically. When you first use an Iteration Layer tool, a browser window will open for you to log in and authorize access.

Available Tools

The MCP server exposes four tools that map to the Iteration Layer APIs:

extract_document

Extract structured data from documents using AI. Supports PDF, DOCX, images (PNG, JPG, GIF, WebP), and text files (MD, TXT, CSV, JSON).

Parameters:

• files (required) — Array of file inputs (each with type, name, and either base64 or url)
• schema (required) — Extraction schema with a fields array defining what to extract

See Document Extraction for the full schema reference.

transform_image

Transform and manipulate images. Supports 23 operations: resize, crop, extend, trim, rotate, flip, flop, blur, sharpen, modulate, tint, grayscale, invertColors, autoContrast, gamma, removeTransparency, threshold, denoise, opacity, convert, upscale, smartCrop, compressToSize.

Parameters:

• file (required) — File input with type, name, and either base64 or url
• operations (required) — Array of transformation operations to apply in order

See Image Transformation for the full operations reference.

generate_image

Generate images from layer compositions. Layer types: solid-color, rectangle, text, static-image, image-overlay, qr-code, barcode, gradient. Layers are composited by index order.

See Image Generation for the full composition schema.

generate_document

Generate PDF, DOCX, PPTX, or EPUB documents from structured definitions. Documents are composed of metadata, page settings, styles, and content blocks (paragraph, headline, image, table, grid, list, table-of-contents, page-break, separator).

See Document Generation for the full document schema.

generate_sheet

Generate XLSX, CSV, or Markdown spreadsheets from structured tabular data. Define columns and positional rows of cells with optional formatting (currency, percentage, number, decimal, date), cell styles, merged cell spans, and Excel formulas. Supports multiple sheets, 162 currency codes, and custom fonts.

See Sheet Generation for the full schema reference.
