Devin Desktop (formerly Windsurf)

App reviews in Devin Desktop (formerly Windsurf)

Windsurf is now Devin Desktop. Add Merci AI once, then ask its agent about your reviews: which ones are waiting, what people complain about, and replies drafted in each reviewer's language.

Set up in a minute

In Merci AI, open Settings › AI assistants (MCP), give the key a name and click Create a key. Copy it now: Merci AI shows it only once.
Open ~/.config/devin/mcp_config.json (on Windows, %APPDATA%\devin\mcp_config.json) and add Merci AI, with your key in place of YOUR_MERCI_KEY:
~/.config/devin/mcp_config.json
```
{
  "mcpServers": {
    "merci": {
      "url": "https://getmerciai.com/api/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer YOUR_MERCI_KEY"
      }
    }
  }
}
```
Devin Desktop's default agent and the older Cascade agent read their MCP servers from this file. If it already lists other servers, add only the merci entry.
Ask in plain words, like the examples below. Every reply waits in Merci AI until you click Publish.

What to ask

“Show my unanswered 1-star and 2-star reviews from this week.”
“Draft replies in the reviewer's language for my German reviews that are still waiting.”
“Which of my apps has the most reviews waiting for a reply?”
“Read my latest 50 reviews and list the bugs people mention most.”
“Write a short, warm reply to the newest review and keep it as a draft in Merci AI.”

What your assistant can do

Read your apps, reviews, drafts and replies, from both stores
Have Merci AI write a reply draft in the reviewer's language, within the store's rules and with your app card's facts
Keep a reply it wrote as the review's draft

What it can't do

Publish anything: a reply goes out only when you click Publish in Merci AI
See any account but yours (or your team's, while you're on it)

Good to know

Each draft Merci AI writes counts toward your plan's drafts for the month.
You can have up to 5 keys and revoke any of them in Settings › AI assistants (MCP); a revoked key stops working at once.
Merci AI keeps only a fingerprint of each key, never the key itself.
