Whisperr agent kit

imageWhisperr

Install Whisperr with the coding agent you already use. Whisperr finds the users who are about to churn and sends the right message at the right time. This kit connects your agent to the Whisperr MCP server and gives it three skills:

Supported stacks: Swift/iOS, React Native/Expo, Flutter, web (React, Next.js, any JS app) and Node. Python, PHP and .NET follow the docs.

MCP server: https://mcp.whisperr.net/mcp (Streamable HTTP, OAuth 2.1). The first tool call opens a browser sign-in. You pick one Whisperr app and approve scopes: data:read, install:write (owners and admins) and changes:propose. You need a Whisperr account.

Install

Claude Code

In a Claude Code session:

/plugin marketplace add WhisperrAI/whisperr-agent-kit
/plugin install whisperr@whisperr

Or from your shell:

claude plugin marketplace add WhisperrAI/whisperr-agent-kit
claude plugin install whisperr@whisperr

Restart the session, run /mcp, select whisperr and sign in. Then ask: "Install Whisperr in this app."

MCP server only (no skills): claude mcp add --transport http whisperr https://mcp.whisperr.net/mcp

Cursor

imageAdd Whisperr MCP server to Cursor

Deeplink (paste into a browser): cursor://anysphere.cursor-deeplink/mcp/install?name=whisperr&config=eyJ1cmwiOiJodHRwczovL21jcC53aGlzcGVyci5uZXQvbWNwIn0=

For the skills and the rule, copy rules/whisperr.mdc to .cursor/rules/whisperr.mdc and the skills/ folders to .cursor/skills/. The full plugin (MCP server, skills and rule) is also available from the Cursor Marketplace after review.

VS Code (GitHub Copilot agent mode)

imageInstall in VS Code

Or from your shell:

code --add-mcp '{"name":"whisperr","type":"http","url":"https://mcp.whisperr.net/mcp"}'

Codex and ChatGPT

Codex CLI, plugin with skills:

codex plugin marketplace add WhisperrAI/whisperr-agent-kit
codex plugin add whisperr@whisperr

MCP server only:

codex mcp add whisperr --url https://mcp.whisperr.net/mcp
codex mcp login whisperr

ChatGPT and the Codex app: install Whisperr from the plugin directory after it is listed. Until then, add https://mcp.whisperr.net/mcp as a custom MCP connection in ChatGPT developer mode.

Windsurf (Devin Desktop)

Devin Local agent:

devin mcp add whisperr https://mcp.whisperr.net/mcp

Legacy Cascade agent: add this to mcp_config.json (~/.config/devin/mcp_config.json; older Windsurf installs use ~/.codeium/windsurf/mcp_config.json):

{
  "mcpServers": {
    "whisperr": { "serverUrl": "https://mcp.whisperr.net/mcp" }
  }
}

Copy snippets/windsurf-whisperr.md to .windsurf/rules/whisperr.md.

Lovable, Bolt, Replit, Rork and other app builders

Use the copy-prompt fallback: snippets/copy-prompt.md. Paste your publishable key and event list into the prompt, then paste the prompt into the tool. Replit also accepts a custom remote MCP server URL.

Any other MCP client

{
  "mcpServers": {
    "whisperr": { "type": "http", "url": "https://mcp.whisperr.net/mcp" }
  }
}

Always-loaded rules for your repository

Agents follow short, always-loaded rules better than on-demand skills. Paste the block that fits your agent into your repository:

Replace the <…> placeholders with your SDK package, version, init file and key variable. The whisperr-install skill offers to do this for you.

What this kit runs, sends and stores

• The kit contains only text: manifests, skills, rules and images. It runs no code on your machine and installs no packages by itself. Your agent runs the commands that the skills describe (package install, build, analyze), in your terminal, with your approval settings.
• The only network destination the kit configures is the Whisperr MCP server https://mcp.whisperr.net/mcp, operated by Whisperr. Your agent sends it tool arguments: event codes, file paths and short code lines for event selection, build results, and your questions about your data.
• Whisperr tools never return delivery addresses (email, phone, push tokens), API keys or secrets. Changes to your workspace are proposals until a member approves them in the Whisperr dashboard.
• The skills tell your agent to send first_name as the only name trait and to send email and phone only as consented channels.

Repository layout

Develop

pip install jsonschema pyyaml
python3 scripts/validate.py --require-schema
claude plugin validate --strict .claude-plugin/plugin.json
./scripts/build-openai-zip.sh

Raise version in .claude-plugin/plugin.json, .cursor-plugin/plugin.json and plugin.json together for every release, then tag vX.Y.Z. The release workflow attaches the OpenAI ZIP to the GitHub release.
