API integration tools and connectors for linking AI systems with external services, databases, and third-party APIs.
220 tools
API integration tools connect AI agents to external services: code hosting, databases, productivity suites, messaging platforms and creative software. Most are MCP servers or SDKs that turn an existing API into tools a model can call, so an assistant can read a repository, query a database or operate an application on your behalf.
Prefer official servers maintained by the service vendor when they exist, since they track API changes and handle authentication properly. Check what permissions the integration needs, whether it offers read-only modes, and how tokens are stored. For databases, look for query limits and safe defaults. If you build your own integration, the official MCP SDKs are the most direct starting point.
