Composio
Managed MCP gateway (1,100+ apps)
Free tier + paidMCP servers & registriescomposio.dev
What it is
An integration platform exposing 1,119+ toolkits and over 20,000 tools behind one managed MCP gateway endpoint. It owns the auth layer, running OAuth flows and storing per-user credentials so your agent never touches raw tokens. The free tier is hard-capped at 100K tool calls and 50K trigger events a month.
Why it earns a slot
One endpoint replaces a dozen separate MCP servers and a dozen separate OAuth setups. Reach for it when an agent needs CRM, email and calendar together and you do not want to wire three token flows.
Know before you commit
Every tool call is metered and a chatty agent burns the free 100K faster than you expect. Composio-managed app connections also cost $0.10 each on paid plans after the first 1,000.
Neighbourhood
How Composio sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
