wehub-resource-sync@composio/google
Adapts Composio tools to Gemini function declarations for the Google GenAI SDK (@google/genai) and executes the function calls the model returns.
Installation
npm install @composio/core @composio/google @google/genai
Set COMPOSIO_API_KEY (create one at https://dashboard.composio.dev/settings) and GOOGLE_API_KEY (from https://aistudio.google.com/apikey) in your environment.
Quickstart
Create a session for your user, pass its tools to Gemini as function declarations, and run the loop: execute each function call with composio.provider.executeToolCall, feed the result back, and repeat until the model replies with text.
import { Composio } from '@composio/core';
import { GoogleProvider } from '@composio/google';
import { GoogleGenAI, type Part } from '@google/genai';
const composio = new Composio({
provider: new GoogleProvider(),
});
const ai = new GoogleGenAI({ apiKey: process.env.GOOGLE_API_KEY! });
// Create a session for your user
const session = await composio.create('user_123');
const tools = await session.tools();
const chat = ai.chats.create({
model: 'gemini-3-pro-preview',
config: {
tools: [{ functionDeclarations: tools }],
},
});
let response = await chat.sendMessage({
message: "Send an email to john@example.com with the subject 'Hello' and body 'Hello from Composio!'",
});
// Agentic loop: keep executing tool calls until the model responds with text
while (response.functionCalls && response.functionCalls.length > 0) {
const parts: Part[] = [];
for (const fc of response.functionCalls) {
const result = await composio.provider.executeToolCall('user_123', {
name: fc.name || '',
args: (fc.args || {}) as Record<string, unknown>,
});
parts.push({
functionResponse: {
id: fc.id,
name: fc.name,
response: JSON.parse(result),
},
});
}
response = await chat.sendMessage({ message: parts });
}
console.log(response.text);
Tool execution
Gemini function calling is non-agentic; the model returns function calls and you execute them. GoogleProvider exposes executeToolCall(userId, functionCall, options?, modifiers?), which takes a { name, args } pair and returns the tool result as a JSON string. The constructor takes no options.
