Hosted Composio MCP alternatives
Composio's appeal is a single hosted endpoint, OAuth-authenticated, that an agent uses to reach 500+ apps with nothing to install. The servers here are hosted the same way: add a URL, authenticate, call the tools. None runs as a local process.
They do not all do the same job, though. Most are automation platforms or aggregators that front many apps; the last three are single-product servers, included because they are common destinations an agent ends up talking to anyway. Each note marks which.
The 8 best hosted alternatives
Activepieces' official server exposes its open-source automation pieces and flows as agent tools over a per-project remote endpoint, a hosted connector layer close in spirit to Composio.
Set up Activepieces →- MakeOfficial
Make's official cloud server turns your Make scenarios into callable tools, so an agent runs multi-step automations you built in Make's editor. It is hosted only and closed source.
Set up Make → - PipedreamOfficial
The nearest hosted aggregator: Pipedream's official server connects an agent to 2,800+ apps and 10,000+ prebuilt actions with managed OAuth and per-app endpoints, broader on app count than Composio.
Set up Pipedream → - WindmillOfficial
Script-first rather than catalog-first: Windmill's official server runs and manages scripts, flows, resources, variables, jobs, and schedules over a hosted endpoint, and exposes your own scripts as agent tools.
Set up Windmill → - ZapierOfficial
The largest app catalog here: Zapier's official server runs actions across 8,000+ apps and 40,000+ actions through a per-account hosted endpoint, and like Make it is closed source.
Set up Zapier → A single destination, not an aggregator: Notion's hosted server searches, reads, and writes across a workspace over OAuth. Worth a direct connection when the only app you need is the one Composio would have proxied.
Set up Notion →Doist's official Todoist server handles tasks, projects, sections, labels, and reminders over a hosted endpoint. Like Notion, it is one product an agent might as well reach directly instead of through a hub.
Set up Todoist →- AssemblyAIOfficial
Narrower still: AssemblyAI's official server lets a coding agent search and read its speech-to-text and audio-intelligence docs over a hosted endpoint, a reference lookup rather than an action-running aggregator.

How to choose
For a hosted hub like Composio, Pipedream and Zapier are the broadest aggregators, and Activepieces is the open-source one. Make exposes scenarios you built; Windmill is an engine for scripts. Notion, Todoist, and AssemblyAI are single products, worth a direct hosted connection when one app or one doc set is all you need rather than a whole catalog. Pick by whether you want reach across many apps or a clean line to one. Setup across all of them is the same: a URL and an OAuth grant or API token, nothing to run.
FAQ
- Is the Composio MCP server hosted or self-hosted?
- Both. Composio offers a managed hosted endpoint over OAuth and an open-source build you can run locally. The servers on this page are all hosted, so the setup matches Composio's hosted mode: a URL and a grant or API token, nothing to run.
- Which hosted alternative reaches the most apps?
- Zapier lists the largest catalog here, 8,000+ apps and 40,000+ actions, with Pipedream close behind at 2,800+ apps and 10,000+ actions. Activepieces is the open-source aggregator. If you only need one app, a direct server like Notion or Todoist is simpler than any hub.
