Overview

Description from the maker (original English)

Build and manage Whalesync syncs: connect apps, map tables and fields, monitor and fix issues.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://api.whalesync.com/mcp

Run this in your terminal

claude mcp add --transport http whalesync https://api.whalesync.com/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "whalesync": {
      "url": "https://api.whalesync.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "whalesync": {
      "type": "http",
      "url": "https://api.whalesync.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Compared with others in Otheri

  • More stars than 0% of the other 32433 servers in this category
  • Published to the registry more recently than 81% of the other 32433 servers in this category
  • Basic checks equal to or better than 100% of the other 32433 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Whalesync safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Whalesync MCP server

Whalesync keeps data in two-way sync between the tools your team already uses — Airtable, Webflow, HubSpot, Salesforce, Notion, Postgres, and more.

This repository is the public home of the Whalesync MCP server: a remote Model Context Protocol server that lets AI agents build and manage syncs for you — create a sync between two apps, map tables and fields, turn it on, and monitor it, including answering "why isn't this record syncing?".

  • Server URL: https://api.whalesync.com/mcp (Streamable HTTP)
  • Auth: OAuth 2.1 with PKCE — your client opens a browser to approve access; no API keys to paste. Read-only access is available at consent time.
  • Docs: https://docs.whalesync.com/api/mcp

The server is remote-only. There is nothing to install from this repository — it exists so directories and registries can link to a canonical public source. The server itself is developed elsewhere.

Install

Cursor — Add to Cursor, or add to ~/.cursor/mcp.json:

{ "mcpServers": { "whalesync": { "url": "https://api.whalesync.com/mcp" } } }

Claude Code

claude mcp add --transport http whalesync https://api.whalesync.com/mcp

VS Code

code --add-mcp '{"name":"whalesync","type":"http","url":"https://api.whalesync.com/mcp"}'

Codex

codex mcp add whalesync --url https://api.whalesync.com/mcp

Claude (web, desktop, mobile) — install from the Claude directory — click Connect.

ChatGPT — install from the ChatGPT app directory — click Connect, or add a custom connector with the URL https://api.whalesync.com/mcp.

Grok — grok.com/connectors → New Connector → Custom → paste https://api.whalesync.com/mcp.

On first use, your client opens a browser window to sign in to Whalesync and approve access. You'll need a Whalesync account.

What the agent can do

24 tools over the Whalesync public API:

  • Build: sync_create, sync_update, sync_list_connectors, sync_list_bases, sync_list_tables, sync_list_fields, sync_get_mappings, sync_update_mappings, sync_validate_mappings
  • Run: sync_activate, sync_pause, sync_delete
  • Monitor & fix: sync_get_status, sync_list_issues, sync_get_issue, sync_retry_issue, sync_list_operations, sync_get_operation, sync_search_records, sync_get_record_status, sync_list_pending_deletes
  • Navigate: sync_list, sync_get, sync_whats_next

Tools are prefixed sync_ because they cover Whalesync's sync feature; other features will arrive under their own prefixes.

Anything irreversible stays human-gated: connecting your apps (OAuth), starting a sync, and approving deletes all happen in the Whalesync app — the agent hands you a link at each step.
