Manage your YaniFend feedback questionary and read collected answers directly from Claude, ChatGPT or Grok via the Model Context Protocol.
YaniFend is a drop-in feedback widget that lets visitors leave structured feedback on **any** website — a single script tag, no framework required (custom sites, SPAs, WordPress, and more). This MCP server lets an LLM client work with the YaniFend backoffice on behalf of a logged-in site owner — list personages, manage questions, and pull in collected answers — without leaving the chat.
Recommended: hosted endpoint
Streamable HTTP transport, OAuth 2.1 (PKCE + RFC 7591 Dynamic Client Registration). No pre-registration — Claude, ChatGPT and Grok register themselves on first connect, then prompt you to log in to YaniFend (Google / GitHub / Facebook / LinkedIn / email).
> **Supported clients:** connecting to the hosted endpoint directly works from **Claude** (claude.ai and the Claude apps), **ChatGPT** and **Grok**. Other MCP clients connecting directly — Claude Code, Cursor and any client whose sign-in returns to a localhost address — are refused at sign-in and are not supported yet.
Claude (claude.ai and the Claude apps)
Add a custom connector:
- **Name:** YaniFend
- **URL:** https://app.yanifend.com/mcp
ChatGPT
Works on the free personal plan.
1. In ChatGPT, open **Settings → Security and login** and turn **Developer mode** on.
2. Open **Plugins**, click **+**, then **Create app → Create MCP App**.
3. Name it **YaniFend**, set **Server URL** to https://app.yanifend.com/mcp, and choose **OAuth** for authentication. ChatGPT finds the sign-in settings itself, so leave the advanced settings as they are.
4. Tick **I understand and want to continue**, then click **Create**.
5. Click **Sign in with YaniFend**, sign in the way you normally do, and approve the request.
6. Back in **Plugins**, open **YaniFend** and click **Refresh** to load its tools.
Grok
1. In Grok, open **Plugins → New Connector → Custom**.
2. Name it **YaniFend**, set **Server URL** to https://app.yanifend.com/mcp, and click **Add Connector**. There is nothing else to type: Grok registers itself.
3. A YaniFend sign-in page opens in your browser. Sign in the way you normally do and approve the request.
4. Start a new chat and ask about your forms.
Claude Code and other MCP clients
Direct connections from Claude Code, Cursor and other clients whose sign-in returns to a localhost address aren't supported yet: their sign-in callbacks are refused, so the connection can't complete. Other assistants haven't been tested. Use Claude, ChatGPT or Grok for now.
Alternative: desktop extension / local stdio proxy (this repo)
This repository ships a stdio MCP server that proxies to the hosted endpoint. Configure it
with your YaniFend account email + password (via the desktop-extension settings, or the
YANIFEND_EMAIL / YANIFEND_PASSWORD env vars) and it signs in over HTTPS and forwards
every tool call to https://app.yanifend.com/mcp — same 33 tools, same schemas and
annotations, strictly scoped to your own account. Without credentials it still serves the
tool catalog for registry introspection and returns a configuration hint on any call.
This is a separate sign-in path from the hosted connector above: it uses your YaniFend email and
password, not the connector's OAuth sign-in, so the supported-clients note above doesn't describe it.
As a **Claude Desktop extension**: install the .mcpb bundle (built with
npx @anthropic-ai/mcpb pack), then enter your YaniFend email and password in the
