"Open Collective" matching MCP servers:

A local MCP server that delegates tasks to a subagent runtime via OpenAI-compatible interfaces, enabling file operations, command execution, and rollback of local file changes.

MCP server that enables searching books by author via Open Library API and searching keywords inside local text files.

Enables AI clients to securely reach and control tools running on your own computers through a relay and outbound device agent.

Enables MCP clients to inspect and export OpenPencil .fig and .pen files directly from disk, supporting operations like info, tree traversal, XPath queries, linting, and conversion to various formats without the desktop app or CLI.

Local-first MCP runtime for fast, reversible, template-aware Excel automation, enabling agents to manipulate live Excel workbooks with safety features like snapshots and rollbacks.

An MCP server for read-only inspection of AutoCAD DWG files, enabling AI agents to open drawings, query objects by handle or filter, and explore properties and references.

A local-first, open-source harness for organizing your files with an AI agent.

Enables running Claude Skills locally on your Mac with sandboxed execution, supporting document processing and integration with MCP-compatible AI tools while ensuring data privacy.

Enables ChatGPT's web interface to operate a real Mac by executing shell commands and reading or writing files over a reverse SSH tunnel, without installing a client or consuming API quota.

Connects AI coding assistants like Claude Code, Cursor, and Windsurf to enterprise data sources (databases, files, APIs, etc.) via a single binary, with 45+ connector categories and built-in memory tools.

Exposes system tools (disk usage, file listing) and weather information via Open-Meteo to MCP-compatible LLMs.

Official MinerU MCP server for parsing PDF, DOCX, PPTX, images, and HTML into Markdown. Supports 109-language OCR, Flash mode (no token), and Precision mode (token)

An open MCP server that gives any AI agent SSH access to remote Linux/Unix machines — shell commands, file read/write, and SFTP transfers.

Official MCP server for UploadKit, the file-uploads platform for developers. Gives Claude Code, Cursor, Windsurf, and Zed first-class knowledge of UploadKit's 40+ open-source React components, Next.js route handler scaffolding, wiring, BYOS (S3/R2/GCS/B2) configuration, and full-text search across 88+ docs pages. Runs locally via npx — no API key, no telemetry, no config.

Enables AI assistants to inspect, create, and report on IFC/BIM files locally, and to open models in a viewer with BCF viewpoint support.

A plain-files brain template and MCP server that lets models read owned, portable working memory via list, read, and grep-style search tools.

Enables AI agents to convert Markdown documents and multi-file books into PDFs, recover Markdown from PDFs that embed their source, and open notes in a live preview GUI, all without a browser, LaTeX, or Pandoc. Each conversion returns the PDF plus page count and rendering diagnostics, and produces byte-identical output on every run.

An MCP server that provides LLMs with full read/write access to an Open Knowledge Format (OKF) knowledge bundle, enabling structured, persistent long-term memory.

Optimize, convert and compare images locally with the same engines as cwebp, cjpeg, oxipng, avifenc and cjxl: WebP, AVIF, JPEG XL, JPEG and PNG. Analyze an image, pick the best format at the same perceived quality (SSIMULACRA 2), measure the loss, crop, resize and convert whole folders. Always writes new files, never overwrites or deletes. Free and open source (GPL-3.0).

MCP server that lets agents edit real Microsoft Word (.docx) documents - tracked changes, tables, styles, comments, content controls, and document properties - with every edit validated and previewed before saving. Built on the Open XML SDK (no Word automation); reads and writes documents in place through filesystem or SharePoint storage.

Enables Claude to open, filter, search, summarize, and write local .xlsx, .xlsm, .xls, and .csv spreadsheets through ten tools, all running locally with no Microsoft Office installed. Access is sandboxed to folders you allow, with an optional read-only mode and an audit log of every file operation.

Enables a planning Claude chat and Claude Code to exchange work through local Markdown files, letting the chat create tasks that code agents pick up, complete, and report back on. Project-scoped task and report tools track each item's status from open through reported, eliminating manual copy-paste between the two clients.

Free, open-source 2D nesting for fixed sheets (laser, CNC, plasma, waterjet, fabric): SVG/DXF import, part-in-part nesting across several sheets, validation and export. Runs as an MCP server, on the command line and in the browser.

Enables Claude to design LEGO models brick by brick, typically from a reference photo, check that they hold together, and export them as LDraw (.ldr) files that Mecabricks and BrickLink Studio open directly. Models autosave for later editing, and very large builds can be generated programmatically.

MCP bridge for Distill — let Claude, Cursor, or any MCP client rename files based on AI content analysis. 9 tools for renaming, suggestions (preview), folder watching, history, and rule management. Five AI providers: Claude, OpenAI GPT-4o, Gemini, Ollama (local), Apple Intelligence. Bridge open-source (MIT), Distill app is commercial (pay-per-use, no subscription).

Enables auditing of every citation in a LaTeX or Markdown manuscript (English or Portuguese) against the actual passage in the cited PDF, verifying quotes literally, fetching sources from local folders, Zotero, arXiv and open-access APIs, and flagging bibliography problems such as retractions or missing DOIs. It also drafts and safely applies approved rewrites or new evidence-backed paragraphs in the .tex file with validation, encoding preservation and backups.

Enables Claude AI to open files and directories with system default applications or specified apps, and reveal items in macOS Finder.

Enables agents to organize messy folders into structured libraries by scanning, planning, and applying reorganization via a manifest-first, non-destructive workflow.

A local, evidence-driven MCP runtime and control plane for open-source maintainers that provides workspace-bounded tools including controlled file operations, command execution, validation primitives, durable execution records, and human review workflows via stdio and Streamable HTTP transports.

Enables AI agents to inspect, read, create, format, edit, validate and convert DOCX, XLSX, PPTX and PDF documents through standard OOXML manipulation plus a locally installed R7 converter, without emulating mouse or keyboard input. It also optionally bridges to a document the user has open in R7-Office Desktop over loopback WebSocket.
