MCP integration
Add this tool to your Model Context Protocol server so AI agents can list and call it.
Server configuration
Add this block to your MCP client configuration:
mcp.json
{
"mcpServers": {
"elysiatools-array-random-sampler": {
"name": "array-random-sampler",
"description": "Randomly select specified number of elements from an array with support for different sampling methods",
"baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=array-random-sampler",
"command": "",
"args": [],
"env": {},
"isActive": true,
"type": "sse"
}
}
}List available tools
After connecting to the SSE endpoint, list the exposed tools:
tools/list
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Call this tool
Invoke the tool by its id, passing arguments built from its parameters:
tools/call
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "array-random-sampler",
"arguments": {
"arrayInput": "Enter array elements separated by delimiter...\napple, banana, orange, grape, mango, peach, kiwi, pineapple",
"delimiter": "comma",
"customDelimiter": "Enter custom delimiter",
"sampleSize": 3,
"samplingMethod": "simple",
"seed": 0,
"allowDuplicates": false,
"preserveOrder": false,
"outputFormat": "table"
}
}
}Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
