"params": {
"name": "file_write",
"arguments": {
"input": "your input here"
}
}
}'
Python Example:
import requests
import json
url = "https://venue-3.covia.ai/mcp"
payload = {

"id": 1,
"method": "tools/call",
"params": {
"name": "file_write",
"arguments": {
"input": "your input here"
}
}
}
response = requests.post(url, json=payload)
result = response.json()
print(result)
JavaScript/Node.js Example:
const fetch = require('node-fetch');
const url = 'https://venue-3.covia.ai/mcp';
const payload = {
jsonrpc: '2.0',
id: 1,
