Windsurf send16 mcp mark_convo_read

How to: Windsurf send16 mcp mark_convo_read

client:Windsurf transport:streamable-http tool:mark_convo_read

Add send16 mcp to Windsurf

  1. 01

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

{
  "mcpServers": {
    "send16-mcp": {
      "serverUrl": "https://mcp.send16.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something mark_convo_read does. Windsurf lists the server's tools on connect and calls mark_convo_read itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that send16 mcp'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

send16 mcp will not start until these are set, so mark_convo_read never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
