The MCP connector library

Your systems.
Your choice of AI.

Find the system you work in. See what your assistant can do, how to connect it, and a useful first prompt. Each guide explains whether it uses connector actions, sync management, workflow triggers, or a custom API workflow.

12 connector guides

8 AI clients · One Stacksync MCP server
CRM

Salesforce

Use Stacksync MCP to inspect Salesforce connections and available actions, plan syncs with a database or CRM, and investigate sync issues from your AI assistant. Salesforce object access and each operation still depend on your connected account.

Connector actionsSync management

Plan a Salesforce reporting replica

Explore setup and workflows
CRM

HubSpot

Bring HubSpot connection discovery, connector actions and sync planning into an AI conversation. Use Stacksync MCP to prepare contact and company mappings, review deal automation, or understand why a HubSpot sync has failed records.

Connector actionsSync management

Plan a contact and company replica

Explore setup and workflows
ERP

NetSuite

Use Stacksync MCP to plan NetSuite customer and transaction syncs, inspect available workflow actions and investigate integration failures. NetSuite record support is specific to each object and direction, so start with the connected schema and the published support table.

Connector actionsSync management

Plan order reporting with line items

Explore setup and workflows
Database

PostgreSQL

Connect an AI assistant to Stacksync to inspect a PostgreSQL connection, prepare bounded SQL queries and plan app-to-database syncs. Query access and sync management are separate operations, with different permission and configuration requirements.

Connector actionsSync management

Prepare a bounded operational query

Explore setup and workflows
Communications

Slack

Use Stacksync MCP to inspect Slack actions and prepare notifications inside broader business workflows. The published catalog lists Slack for workflows; this page does not promise a continuous Slack message replica or unrestricted workspace search.

Connector actions

Design a sync-issue alert

Explore setup and workflows
Developer tools

GitHub

Build a GitHub workflow through Stacksync MCP using documented HTTP or code steps when the required action is not in the live catalog. The reviewed public catalog does not establish a native GitHub connector, so these examples are custom integration plans.

Custom API workflow

Plan a repository issue digest

Explore setup and workflows
Productivity

Notion

Prepare a custom Notion integration with Stacksync MCP using HTTP or code workflow steps. The reviewed Stacksync catalog does not list Notion, so page retrieval, data-source queries and updates require a verified API implementation rather than an assumed native connector.

Custom API workflow

Design an overdue-task review

Explore setup and workflows
Communications

Gmail

Use Stacksync MCP to design workflows that start from Gmail. Stacksync documents a built-in new-message trigger; broader mailbox search or draft operations must be verified in the catalog or implemented as custom Gmail API steps.

Workflow triggerCustom API workflow

Design a new-email intake workflow

Explore setup and workflows
Commerce

Shopify

Use Stacksync MCP to prepare Shopify order and product syncs, inspect connector actions and investigate failed updates. Start with the store connection and supported objects, then choose the data and write direction needed for the commerce workflow.

Connector actionsSync management

Plan an order-reporting replica

Explore setup and workflows
Customer support

Zendesk

Plan Zendesk ticket reporting, inspect connector actions and diagnose support-data sync issues through Stacksync MCP. Ticket, comment and user sync support is documented; other object types may require access to be requested.

Connector actionsSync management

Database

Airtable

Use Stacksync MCP to inspect Airtable connections, prepare table syncs and discover available record actions. Plan base and field access explicitly, and account for the separate refresh behavior of calculated formula values.

Connector actionsSync management

Plan an Airtable reporting table

Explore setup and workflows
Productivity

Google Sheets

Use Stacksync MCP to discover Google Sheets actions and design spreadsheet workflows. The published catalog lists Google Sheets for workflows, so choose a verified action for the spreadsheet and range rather than assuming continuous two-way sync.

Connector actions

Plan a spreadsheet report refresh

What your AI can do

Build the stack by asking for it.

  • Create a sync

    Two-way sync between your CRM, ERP and database, mapped from a prompt.

  • Create a workflow

    Build, deploy, run and replay workflows, and review their runs.

  • Create an AI Genie

    An agent that answers questions and acts over your connected data.

  • Create an API proxy

    One endpoint and one token for a connected app's API, for your own code.

Setup

Connect your AI client.

Pick your assistant. Sign-in uses OAuth, so there are no API keys to create or paste into a chat.

What you can ask

Say what you need. Your assistant does the work.

When an app isn't connected yet, your assistant gives you a secure sign-in link to open. Your credentials never go through the chat.

Start here

“Connect my apps and help me set up Stacksync from this chat.”

Resource Your assistant can Try asking
Two-way syncs Create and edit syncs, select tables and fields, pause and resume them, and resolve sync issues.
  • Create a two-way sync between Salesforce and PostgreSQL.

  • Which syncs in this workspace have open issues? Resolve them.

Workflows Build, deploy, run and replay workflows, and review their runs.
  • Build a workflow that posts closed HubSpot deals to Slack.

  • Show me the failed runs of the order workflow this week and replay them.

Genies Create and configure Genies, send them requests and approve their actions.
  • Create a Genie that answers questions about open orders from our NetSuite data.

  • Show the Genie actions waiting for my approval.

Connections Connect apps through a secure sign-in link you open, and list their tables and fields.
  • Connect our HubSpot account and list the tables it has.

Queues Put managed queues in front of workflows and see what is waiting in them.
  • Put a queue in front of that workflow so bursts are processed at a steady pace.

  • How many messages are waiting in the orders queue?

Variables and secrets Read and write the variables and secrets your workflows use.
  • Store our NetSuite account ID as a variable that every workflow can read.

Knowledge bases Give Genies documents and context to answer from.
  • Add our returns policy to the support knowledge base.

API proxies Give your own code one endpoint for a connected app's API.
  • Create an API proxy for our HubSpot connection.

Security and control

Production guardrails, built in.

An assistant can follow instructions it finds in the data it reads. For workspaces with production data, turn on Ask before every change and review each proposed change before you accept it.

  • Your Stacksync login

    Your assistant signs in through OAuth. There are no API keys to create, share or paste into a chat.

  • Your permissions, nothing more

    It acts with your role in each workspace and sees only what you can see in the Stacksync app.

  • Read-only when you want it

    Clear Make changes on the sign-in page to give an assistant read access only.

  • Ask before every change

    Workspace owners can require a preview of every create, update, delete or run, which runs only after you accept it.

  • Revoke at any time

    The Sessions tab lists the assistants you have signed in. Revoke ends a session immediately.

  • Rate limited

    Each user and each workspace API key can make up to 120 tool calls per minute.

Skills

Stacksync skills teach your assistant to build it right.

The MCP server does the work; skills describe how. Each one covers a build or a fix: which questions to ask first, the steps in order, and the rules that keep a live account safe. They follow the open Agent Skills standard, and your assistant reads a skill only when a request needs it.

Claude and ChatGPT

Nothing to install: once the Stacksync MCP server is connected, it serves the skills to your assistant. In Claude you can also upload the skills ZIP under Customize → Skills.

Claude Code

Install the Stacksync plugin, which also connects the MCP server.
