A native Nextcloud app that exposes the instance as an MCP server so Claude and other MCP clients can read, search, and (with admin-granted permissions) edit files, notes, calendars, Deck cards, and Talk conversations. It runs inside Nextcloud with OAuth or app-password sign-in, applying each user's own Nextcloud permissions and admin-controlled per-operation grants.

A powerful MCP server for Excel operations with seamless Supabase Storage integration.

MCP server for Claude Code CLI that integrates with Google Workspace, enabling management of Docs, Sheets, Drive, Gmail, Calendar, and Apps Script.

A robust MCP server that transforms OneNote notebooks into an AI-accessible knowledge base for Gemini Spark, enabling natural language queries to list, read, and search notes via Microsoft Graph API.

Enables task management through MCP tools, resources, and prompts, backed by a PostgreSQL database.

Enables OAuth2-authenticated clients to search and read on-premises Exchange mail, download attachments, manage drafts and confirmed sending, update read flags, move messages, look up directory entries, and access personal calendar events through EWS, with LiteLLM integration.

Enables AI agents to discover and work with a user's permitted Excalidraw boards through a single MCP endpoint, reading and adding elements, images, and snapshots while respecting owner, view, edit, and guest-link access controls.

A standalone remote MCP server that lets AI clients read, search, post, schedule, and manage messages and files in Mattermost as each individual user through per-user OAuth, without requiring a plugin or Enterprise license. It keeps each user's Mattermost tokens server-side, enforces per-user permissions and API limits, and ships guard rails against duplicate or unintended posts.

Enables AI agents to manage citations in Microsoft Word via EndNote, including DOI-verified paper search, RIS import/export, and genuine CWYW IEEE citations.

Enables Claude to manage Apple Reminders on macOS, providing full CRUD operations such as listing, searching, creating, updating, and deleting reminders.

Enables AI agents to manage n8n workflow automation instances through tools for workflow CRUD operations, execution monitoring, and webhook triggering. It facilitates programmatic interaction with n8n instances via the n8n API with AI-optimized descriptions and error handling.

Enables AI assistants to interact with Slack workspaces by listing channels, posting messages and thread replies, adding emoji reactions, retrieving channel history and thread replies, and inspecting user profiles. Supports both stdio and Streamable HTTP transports for flexible integration.

A self-hosted Model Context Protocol server for Microsoft To Do. The key problem this solves: the Microsoft Graph API silently omits user-created lists on personal accounts (GET /me/todo/lists only returns well-known lists like "Flagged Emails"). This server works around it with a local SQLite registry that tracks every list you create, so your lists always show up.

Enables posting text messages to Google Chat spaces through webhook-based integration, providing simple and secure message delivery without OAuth setup requirements.
