Windsurf Aetherya aetherya_simulate_post

How to: Windsurf Aetherya aetherya_simulate_post

client:Windsurf transport:streamable-http tool:aetherya_simulate_post

Add Aetherya to Windsurf

01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mcp": {
      "serverUrl": "https://mcp.aetherya.ai/mcp"
    }
  }
}

02
Save the file and restart Windsurf.
03
Ask for something aetherya_simulate_post does. Windsurf lists the server's tools on connect and calls aetherya_simulate_post itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Aetherya's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Set these first

Aetherya will not start until these are set, so aetherya_simulate_post never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
