SETUP GUIDE
Connect GLEIF API MCP Tool with your Agent
1
Install Composio
typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcpInstall the Composio SDK for Python or TypeScript
2
Initialize Client and Create Tool Router Session
typescript
import { Composio } from '@composio/core';
const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);Import and initialize the Composio client, then create a Tool Router session for GLEIF API
3
Connect to AI Agent
typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';
const client = await createMCPClient({
transport: {
type: 'http',
url: session.mcp.url,
headers: {
'x-api-key': 'your-composio-api-key',
},
},
});
const tools = await client.tools();
const { text } = await generateText({
model: openai('gpt-4o'),
tools,
messages: [{
role: 'user',
content: 'YOUR_SPECIFIC_PROMPT_HERE'
}],
maxSteps: 5,
});
console.log(`Agent: ${text}`);Use the MCP server with your AI agent (Anthropic Claude or Mastra)
