FindUtils MCP

What FindUtils MCP MCP server does

FindUtils MCP MCP server provides AI agents with a remote collection of utility operations through the Model Context Protocol. The catalog is described as containing 388 tools, spanning data formats, encoding, hashing, conversion, generation, and other developer-oriented tasks.

The tools return structured results appropriate for agent workflows. For example, PDF extraction can return text and positional JSON, invoice generation returns a base64-encoded PDF, and bookmark converters return formats such as CSV, Markdown, or Netscape HTML. Several tools also expose validation details, counts, schedules, or generated source alongside the primary result.

How it works

An MCP-compatible AI client calls a named FindUtils operation with its input parameters. The operation performs the conversion, calculation, generation, or analysis and returns the result to the client. Some operations are deterministic: avatar generation is seeded from the normalized input, while encoding tools follow formats such as RFC 4648 Base32 and Base64.

The catalog also includes a group of A2UI-specific tools. Agents can retrieve protocol documentation, obtain the basic catalog schema, request canonical examples, compare two JSONL payloads, generate a system prompt, and validate generated JSONL with line-specific diagnostics. These tools are relevant when an application produces A2UI content and needs reference material or pre-delivery checks.

Inputs vary by operation. PDF extraction accepts either a public HTTPS PDF URL or a base64-encoded PDF, while bookmark tools consume exported browser files or supported JSON structures. Calculator tools accept domain-specific values such as dates, loan rates, dimensions, or body measurements.

Tools and capabilities

Representative capabilities include:

• Generate invoices as PDF files and avatars or barcodes as SVG.
• Extract PDF text and structured bounding-box data.
• Encode and decode Base32 or Base64 text.
• Convert subtitle files, browser bookmarks, and API endpoint lists.
• Calculate age, BMI, body composition, auto loans, and amortization schedules.
• Generate API documentation as Markdown or OpenAPI 3.0.3 JSON.
• Inspect robots.txt rules for 24 named crawlers.
• Produce CSS box-shadow declarations and aspect-ratio calculations.

The bookmark tools preserve or transform folder structures, dates, titles, and URLs according to each operation's documented format. They do not fetch bookmarked pages. The A2UI validator can check a payload against the basic catalog or a supplied custom catalog.

Limitations and notes

Those details should be confirmed from the service's own documentation before deployment.

Some operations have explicit input limits or format constraints. PDF extraction is intended for documents under 10 MB, and the API and MCP surfaces for browser bookmark HTML accept up to 1 MB, although the browser page accepts 10 MB. A PDF URL may fail when the source blocks server requests; sending the file as base64 is the documented alternative.

The tools generally operate on supplied data rather than retrieving external content. Bookmark conversion does not test links, and the bookmarks diff tool does not fetch them. Format-specific restrictions also apply: barcode symbologies accept different character sets, and bookmark JSON conversion supports only the documented Chromium, Firefox, and plain-tree shapes.
