Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to whalesync.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote Whalesync MCP server that lets an assistant build, run and monitor two-way data syncs between apps like Airtable, Webflow, HubSpot, Salesforce, Notion…

What you can do: Create and update syncs, and list connectors, bases, tables and fields
Read, update and validate table and field mappings
Activate, pause and delete syncs
Check sync status, list and inspect issues, retry failed issues, review operations and pending deletes
Search records and check why a specific record is or isn't syncing
List and look up syncs and get suggested next steps
When to use it: Useful when a team keeps data in two-way sync between SaaS tools or databases and wants an assistant to set up mappings, turn syncs on or off, and diagnose records that are not syncing, without clicking through the Whalesync UI.
Requirements: Remote Streamable HTTP endpoint at api.whalesync.com/mcp; nothing to install locally. Requires a Whalesync account and OAuth 2.1 with PKCE sign-in through a browser; no API keys. Read-only access can be chosen at consent time.

Before you install

The agent can change data: it creates and updates syncs and mappings, activates, pauses and deletes syncs, and retries issues. Irreversible steps such as connecting apps, starting a sync and approving deletes are handed off to the Whalesync app as human-gated links. Grant read-only access at consent if you only want monitoring.

Installation

In SourceWeft

Open Whalesync in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.whalesync%2Fwhalesync/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

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:

Claude Code

VS Code

Codex

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.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
