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-pendulum-calculator": {
"name": "pendulum-calculator",
"description": "Compute period, length, or gravity of a simple pendulum, plus amplitude-based peak speed and energy",

}
}
}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": "pendulum-calculator",
"arguments": {
"solveFor": "period",
"period": 0,
"length": 1,
"gravity": 9.80665,
"amplitude": 10,
"mass": 0.5
}
}
}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).
