MCP server

The welaunch MCP server

welaunch finds where people who need what you sell are already looking, on ChatGPT, Google, Reddit and X, and writes the posts, replies and pages that bring them to you. As an MCP server, it does that from any agent that speaks MCP: Claude Code, Cursor, Windsurf, the Claude app, or one you built. Ask it to run a play, read the five replies it wrote, and send the ones you like to your browser.

Install

Make a key in Settings, MCP server (a free account is enough to read plays; running steps needs Growth). Then:

Claude Code

claude mcp add --transport http welaunch https://api.welaunch.sh/mcp --header "Authorization: Bearer wl_YOUR_KEY"

Cursor, Windsurf, the Claude app: add to mcp.json

{
  "mcpServers": {
    "welaunch": {
      "url": "https://api.welaunch.sh/mcp",
      "headers": {
        "Authorization": "Bearer wl_YOUR_KEY"
      }
    }
  }
}

What you can ask

"What are my top plays this week?"
"Run the Reddit step on the r/SaaS play and show me the replies."
"Rewrite the third one, less salesy."
"Send the first two to my browser."
"Score competitor.com and tell me what they get wrong."
"How is my visibility on ChatGPT compared to last week?"

free

Two rules

Nothing is posted from the MCP. post_target queues the draft for the welaunch Browser Agent, the Chrome extension in your own browser, which opens the page, fills the reply in, and waits for you to press submit. An assistant with a tool that posts to Reddit on its own is how accounts get banned; yours never has one.

Every key has a daily credit ceiling, 50 by default, set per key in Settings. A step that finds and writes costs 8 credits; an agent in a loop stops at the cap, not at your balance.

The skill

Agents that load skills can take /skills/welaunch/SKILL.md: when to reach for welaunch, how to read a play, and how to talk about drafts (as drafts, until the founder presses submit).
