The Tool Library provides ready-made integrations that your AI agents can use during conversations. No coding required—just add the tool, configure the settings, and your agent can book appointments, send messages, fetch data, and more.
How it works: When you add a tool to your agent, it becomes available for
the agent to call during conversations. The agent decides when to use each
tool based on your prompt instructions.
Built-in tools are attached after the agent is created:
POST /agent/tool/{agent_id}/
{ "type": "builtin", "builtin_key": "send_sms", "name": "send_sms", "description": "Send an SMS to the current contact.", "config": {}, "is_success": false, "is_prerun": false, "is_postrun": false}
builtin_key is the important field. Use config to pre-fill tool inputs so
the agent does not need to supply them during the conversation.
Set is_success: true when a successful run of this tool should mark the
conversation as successful. The backend returns the attached tool with
builtin_key, display_name, and the resolved schema.
Understanding the difference between variables and configurations is key to using tools effectively.
Variables
Filled by the agent during the conversation The agent gathers this
information from the customer and passes it to the tool. Examples: -
Customer’s name - Preferred appointment time - Email address - Phone number
Configurations
Preset when you add the tool You configure these once, and they stay the
same for every call/chat. Examples: - API keys - Calendar IDs - Default
timezone - Integration credentials
Example:When using the “Fetch Free Slots” tool:
Configuration: You set the Calendar ID once (which calendar to check)
Variables: The agent fills in the start_date and timezone during each conversation
Connect to 60+ popular applications through MCP application integrations. These applications are available as preset MCP servers—simply authenticate and select which tools you want your agent to access.
How it works: When you add an MCP application integration, you’ll
authenticate your account and then choose specific tools/actions from that
application. Your agent can then perform those actions during conversations.
See the MCP Server section for detailed setup
instructions.

Authentication Required: Most applications require OAuth2 or API key
authentication. When you add an application integration, you’ll be guided
through the authentication process. Some applications may already be
authenticated if you’ve connected them previously.
Granular Tool Selection: After authenticating an application, you can
choose which specific tools/actions your agent can access. For example, with
Gmail, you might only allow creating draft emails but not sending or reading
emails. This gives you fine-grained control over what your agent can do.
