aci vs restheart

aci: ACI.dev is an open-source tool-calling platform designed to connect over 600 tools to any AI agent or agentic IDE. It provides intent-aware tool access with multi-tenant authentication, granular permissions, and dynamic discovery through a Unified MCP server or a lightweight SDK.; restheart: RESTHeart exposes your data through a native MCP server and full REST and GraphQL APIs, so AI agents and developers can read and write without custom integration code. It ships with authentication, authorization, and a plugin system for custom business logic. Available as Docker image and GraalVM native binary.

TL;DR

aci logo
aciAPI Integration · ★ 4.9k
When to choose:
  • You want 600+ pre-built integrations with built-in OAuth and secrets management, so you do not write a client per service.
  • You want dynamic tool discovery so tool definitions stay out of the context window.
  • You want to use it as an MCP server or through Python and TypeScript SDKs, with no framework lock-in.
When to skip:
  • You want a single MCP server to install: the MCP server lives in a separate repository, and self-hosting runs a backend plus a portal.
  • You do not want user credentials and tool calls to pass through a third party: that is how the managed service works.
  • You need a very actively developed project: our data shows the last push on 2026-05-28.
