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-arrhenius-equation-calculator": {
"name": "arrhenius-equation-calculator",
"description": "k = A·e^(−Ea/RT) solved for k, A, or Ea (two-point form), with Ea in kJ/mol and kcal/mol.",

"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": "arrhenius-equation-calculator",
"arguments": {
"solveFor": "k",
"aFactor": 10000000000000,
"rateConstant": 0,
"ea": 75,
"eaUnit": "kJ",
"temp": 298.15,
"tUnit": "K",
"k1": 0,
"t1": 0,
"k2": 0,
"t2": 0
}
}
}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).
