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-hydrogen-spectrum-series": {
      "name": "hydrogen-spectrum-series",
      "description": "Rydberg lines for Lyman/Balmer/Paschen/Brackett/Pfund: vacuum wavelengths, photon energies, named lines with Balmer colors, series limit.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=hydrogen-spectrum-series",
      "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": "hydrogen-spectrum-series",
    "arguments": {
  "series": "balmer",
  "maxUpper": 10
}
  }
}

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).
