"How to obtain an API key" matching MCP servers:

Compress, merge, split, OCR and convert PDFs (Word, Office, images, webpages) on local files, plus password protect and unlock, through the Papyrio API. Works without a key on a free guest tier; an optional RapidAPI key raises the limit.

Enables local conversion of PDFs to Markdown, with automatic OCR fallback for scanned pages, image extraction, and page-by-page structure preservation.

Enables an AI agent to send files end-to-end encrypted, encrypting on the user's computer and keeping the download link key, password, and login away from the model.

Enables AI agents to download signature-verified Android APKs from RuStore by package name, with no browser, account, or API key required.

Lets an agent read local documents as Markdown: PDF, Word, PowerPoint, Excel, CSV, HWP/HWPX, OpenDocument, RTF, EPUB, HTML and email. Tables keep their rows and columns, and long files can be read one page, slide or sheet at a time. Offline, read-only, no API key.

Local-first operator MCP server: recall across your own sessions, chats and files, an encrypted vault, SSH to your own hosts, and gated shell, browser and device tools. 130 tools over stdio or HTTP; everything runs on your machine — no hosted service, no account, no API key.

Extract text and Markdown from local PDFs and images. Uses native PDF text first and Apple Vision OCR on macOS. No OCR API key required.

Converts customer-supplied PDF bank statements into checked Excel, CSV, or JSON with balance validation. Runs locally with your own MainBook API key or against MainBook's hosted endpoint, and it never connects to bank accounts.

50 tools and 400 functions for working with Excel/.xlsx spreadsheets — read/write, recalculate formulas, diff, repair broken references, and audit. Built for AI agents.

Fast, local PDF parsing as an MCP server with text extraction, bounding boxes, OCR, and visual citations. No cloud or API key required.

A read-only MCP server that exposes AI Disk Doctor Core's scan, model inventory, and history tools via local stdio, with no mutation or shell capabilities.

Local Dev Doctor turns an unfamiliar development checkout into an evidence-backed diagnosis. It discovers how the project is meant to run, checks safe prerequisites, and executes only the exact probe that a user approves.

locidx

Provides a workspace-scoped terminal and file tools over MCP, enabling an agent to run commands, manage interactive sessions, and read, list, search, and edit files.

Enables MCP clients to upload local files, create default 24-hour controlled download links, and list, inspect, or permanently delete owned files and shares via a dedicated API key.

Provides intelligent file system operations with advanced features including code analysis and modification across multiple languages, version control (Git/GitHub), file compression, encryption, semantic search, batch operations, and secure shell command execution.

Sends document files (EPUB, PDF, DOCX, etc.) to your Kindle via email using Amazon's Send to Kindle feature.

Enables an AI agent to compute path-level semantic differences between two JSON, YAML, TOML, CSV, .env or INI files or pasted strings — matching lists by key so moves aren't reported as edits, honoring numeric tolerance and ignore patterns, and returning verified RFC 6902 patches. It also streams keyed CSV row diffs and inspects how a file parses, all read-only within allowed folders.

Local-first MCP server for working with an Obsidian vault. No API key required

Bridges a remote, cloud-hosted agent to your local machine, exposing Pi's coding tools (read, write, edit, ls, grep, find, bash, powershell) rooted at a directory you choose. It also adds a human channel so the agent can message, question, and wait on you through tool calls instead of a platform chat UI, with OAuth 2.1 or bearer-token authorization and no persistence between runs.

AI-powered MCP server for file renaming, organization, and PDF splitting using natural language prompts and content analysis.

Enables AI agents to convert PDF, Word, PowerPoint and Excel documents — from a public URL or a local file — into Markdown by calling the Unfold API with the user's own marketplace key, with clear quota and error reporting.

Local MCP server for PDFs: read PDFs into Markdown with tables, charts and OCR, export to Word, PowerPoint, EPUB and Excel, and merge, split, fill, compare and edit PDFs. Works only inside the folders you allow; nothing is uploaded.

A Model Context Protocol server that wraps the official Obsidian CLI to allow AI agents to read, write, search, and manage notes within an Obsidian vault. It provides 16 specialized tools for comprehensive vault interaction, including note management, task tracking, and metadata manipulation.

A Model Context Protocol server that converts Markdown documents to plain text with flexible options and dual protocol support.

A beginner-friendly MCP server built in plain Node.js/JavaScript that exposes five tools (calculator, UUID generator, read notes, get weather, password generator) to teach how the Model Context Protocol works under the hood.

An MCP server that allows users to upload projects (single files or directories) to the Yourware platform, enabling easy deployment and showcasing of projects.

A cross-platform MCP server providing persistent storage for AI assistants to store, retrieve, and manage memories across conversations. It features keyword and tag-based search capabilities using a local JSON file for data persistence.

Turns invoice details from an MCP client conversation into calculated totals and formatted Excel workbooks in JPY, USD, or EUR, using integer minor-unit arithmetic and grouped tax rounding. Supports mixed tax rates, Excel formulas with cached totals, and A4 print-ready layouts, writing files locally with no network access or API key.

Provides file search functionality with tools for both partial keyword matching and exact word search, returning detailed results with line numbers and column positions.

An MCP server that converts Markdown files containing Mermaid diagrams into PDF documents by rendering diagrams as SVG images. It provides a specialized tool to automate document conversion while ensuring all visual charts are correctly embedded in the final output.

An MCP server that allows Claude AI to perform filesystem operations including reading, writing, listing, moving files, and searching directories within specified allowed paths.

Enables any MCP-compatible AI, whether in the browser or running locally, to create and edit projects, run terminal commands and long-running jobs, and optionally use Docker, all guarded by a policy engine, workspace jail, authentication, and audit logging.

A bridge server that allows LLM tools to interact with an Obsidian vault through a local REST API, enabling file operations, note management, and metadata access through natural language.

Enables Claude Desktop and Claude Code on macOS to read local invoice files and match them against Folio Norway bank transactions, events, and existing attachments. After an explicit human approval step in the terminal, it uploads the approved document as an attachment to the chosen Folio event using a user's own API key stored in the macOS Keychain.

Enables autonomous web research, file management, and dynamic UI dashboard generation through Gemini LLM and FastMCP.

A local MCP server for Cursor that converts Markdown files and Mermaid diagrams to JPEG images with configurable dimensions and quality.

An implementation of the Model Context Protocol that allows AI models to interact with 360 AI Cloud Drive, providing comprehensive file management capabilities including uploading, downloading, searching, and sharing files.

Enables conversion of multiple file formats (Markdown, HTML, Word, Excel, etc.) to XMind mind maps with AI-powered analysis for structure optimization and quality assessment.

Converts documents (PDF, Word, PPT, images, HTML) to Markdown via MinerU API. Supports URL and local file inputs with OCR, formula/table recognition, and automatic large file handling.
