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-function-equation-plotter": {
"name": "function-equation-plotter",
"description": "Plot one or more y=f(x) expressions, mark roots and extrema, and generate SVG-ready graph output",
"baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=function-equation-plotter",
"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": "function-equation-plotter",
"arguments": {
"expressions": "x^2 - 2*x\nsin(x)",
"xMin": -2,
"xMax": 4,
"yMin": -2,
"yMax": 4,
"sampleCount": 240,
"integralFrom": 0,
"integralTo": 3.1416
}
}
}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).
