"An MCP that effectively manages other MCPs" matching MCP servers:

Local macOS MCP servers for Mail, Calendar, Reminders, Notes, Contacts, Messages, Shortcuts, Files, Maps, and system tools. The unified Apple Tools server and individual app servers run over stdio with native macOS permissions; this is an MIT-licensed community project, unaffiliated with Apple.

A production-grade MCP server framework providing multiple specialized servers for tabular data, documents, calendars, markdown, prompt engineering, and general utilities.

Provides comprehensive integration with Microsoft Outlook for managing emails, contacts, calendars, and folders through the Microsoft Graph API. It offers 26 specialized tools to perform actions like sending emails, scheduling meetings, and organizing mail folders.

Enables AI assistants to interact with Gmail accounts for searching, reading, sending, and managing emails through secure OAuth2 authentication. It provides comprehensive tools for message operations, conversation threads, and account statistics using the FastMCP framework.

Enables Claude to interact with Trello boards, lists, cards, comments, and attachments through natural language commands. Uses Nango OAuth authentication to provide complete Trello API coverage including creation, updates, search, and project management operations.

Enables task and project management in Todoist through natural language, supporting creating, listing, and completing tasks, as well as managing projects and labels with Nango OAuth authentication.

Connects AI assistants to Notion workspaces, allowing users to search, create, and manage pages or databases through natural language conversations. It supports complex database querying, content updates, and workspace organization via the Model Context Protocol.

MCP server that reads and writes the system clipboard — tables, text, code, JSON, URLs, images, and more. Preserves spreadsheet structure (rows/columns) that is lost when pasting into Claude directly.

A macOS-only MCP server that lets Claude read and create events in Apple Calendar, list calendars, and find free time using EventKit.

Turns markdown the agent produced into a link that renders as a typeset, paginated document with tables, Mermaid and math. The document is encoded in the URL, so nothing is uploaded and no account is needed.

Enables creating PDF documents (invoices, certificates, reports, etc.) from natural language descriptions, returning a shareable link to preview and edit the document.

Bridges the editing capabilities of an already-open DingTalk document in the browser to any MCP host via standard stdio, forwarding tools to the page's internal MCP server over a local WebSocket. Supports read/write operations through suggested edits, pairing-based security, and zero runtime dependencies.

MCP server for Differino that lets AI agents compare PDF, DOCX, and TXT documents, with tools for visual and text diffs, summaries, exports, and account balance checks.

Convert Markdown into boardroom-grade DOCX, PDF, and HTML using your own custom Word templates — or any of MDMagic's 15 designer-built ones across Business, Creative, Professional, and Technical. Ten tools cover conversion, template recommendations, cost estimation, and markdown validation.

A minimal MCP server for sending Slack messages, supporting both bot and user tokens with concurrent safety and an AI bot signature in user-token mode.

MCP server for evidence-based bullet point summarization guidance. Validates and improves bullet lists using scientifically-validated principles from cognitive psychology and UX research.

An MCP server that enables human-in-the-loop elicitation, letting AI agents ask users questions via tools like elicit_confirm and elicit_form, with diagnostics to verify host elicitation support.

Enables adding inline, range-anchored comments to specific text fragments in Google Docs, overcoming the limitation that Google APIs cannot create anchored comments.

Local, read-only-by-default MCP server for Weeek that connects AI clients to your workspace over stdio, enabling listing projects, tasks, boards, members, and tags with opt-in write tools for task management.

An MCP server for Google Docs whose writes carry proof, ensuring every mutating operation re-reads the document and returns evidence of changes with tab-scoped edits, normalization ladder, and match-count guards.
