TOOL CALL

Give your AI agents the power to act, not just talk

Connect agents to your existing APIs, databases, and third-party services. Tool Call lets AI execute real actions — with guardrails, logging, and full control.

Connect Your First Tool
tool-call.ts
agent.registerTool({
  name: "create_ticket",
  description: "Create a Jira ticket",
  parameters: {
    title: { type: "string" },
    priority: { type: "enum",
      values: ["high","medium","low"] }
  },
  execute: async (params) => {
    return jira.createIssue(params);
  }
});
Integrations

Connect anything your business runs on

From REST APIs to databases to custom code — Tool Call supports every integration pattern.

REST API

Connect any RESTful endpoint with automatic schema discovery and request/response mapping.

Webhooks

Trigger and receive webhooks for real-time event-driven automation between services.

Database

Query SQL and NoSQL databases directly. Read, write, and transform data within agent workflows.

HOW TOOL CALL WORKS

Define → Discover → Execute → Return

  1. 01

    Define your tools

    Describe your API endpoints, parameters, and expected responses using our visual tool builder or JSON schema.

  2. 02

    Agent discovers & selects

    The AI agent understands when to call which tool based on user intent, context, and your routing rules.

  3. 03

    Execute with guardrails

    Every tool call goes through validation, rate limiting, and permission checks before execution.

  4. 04

    Return & continue

    Results flow back into the conversation. The agent can chain multiple tools or ask for clarification.
