Give AI assistants and agents access to external applications, APIs, and services.
Showing 6 of 6 tools
These tools give AI assistants and agents access to external apps, APIs and data, such as email, CRMs, databases and file storage, so they can look up information and take actions. They include MCP servers, integration platforms and tool-calling frameworks.
Choosing an integration approach
MCP servers connect assistants to tools through a standard protocol; integration platforms offer many ready-made connectors; frameworks let developers define custom tools. Compare available connectors, authentication, permission scopes, logging and hosting options.
Secure connections
Give AI the narrowest access needed, prefer read-only permissions at first, store credentials securely and log every action. Watch for prompt injection, where content from an email or web page tries to trick the AI into misusing a tool.
