Agentic AI

Tool Calling

Tool calling is the ability of an AI model to autonomously invoke external tools — querying databases, calling APIs, or processing files. Instead of only generating text, the agent can act in the real world. IJONIS uses tool calling to seamlessly connect AI agents with existing enterprise systems.

Why does this matter?

Tool calling makes the difference between an AI assistant that only responds and an AI agent that actually acts. Your agent can create orders in the ERP, update CRM entries, or run calculations in Excel — all controlled through natural language.

How IJONIS uses this

We define type-safe tool interfaces using the OpenAI Function Calling standard and LangChain Tool Abstractions. Every tool includes validation, error handling, and audit logging — ensuring the agent operates reliably and traceably.

Frequently Asked Questions

Which systems can an AI agent connect via tool calling?

Any system with an API or programmatic interface: ERP systems (SAP, Microsoft Dynamics), CRM (Salesforce, HubSpot), databases, email servers, cloud storage, and even legacy systems via wrapper APIs.

Is tool calling safe for business-critical systems?

Yes, when properly implemented. We use permission levels, parameter validation before execution, confirmation loops for critical actions, and complete audit logging. The agent can only use tools that are explicitly authorized.
