Workspace369 publishes this guide and makes one of the MCP servers it describes. Other vendors' connectors are described from their own pages, not tested.

A CRM MCP server lets an AI client work with your CRM instead of only talking about it. You ask, and the AI reads your client records, drafts the invoice or logs the time, and the result lands in the workspace. Workspace369 has an MCP server on every plan, once a workspace admin turns on AI connections.

Key takeaways

  • A CRM MCP server lets an AI client such as Claude or ChatGPT read and act on your client records, proposals, invoices, projects, calendar and inbox through the Model Context Protocol.
  • Workspace369 has an MCP server on every plan once an admin turns it on. You choose what each connection may do, and anything that sends waits for your approval.
  • HoneyBook, Bonsai and Moxie also offer AI connectors now (Moxie's MCP server is on Pro and Teams, Bonsai's needs a paid plan, checked October 27, 2026), so the useful questions are which plans include it, what it can write, and what it holds back.
  • Claude, ChatGPT, Grok, Cursor and Windsurf are listed on the Workspace369 MCP integration page; each tool call draws from the plan's monthly AI usage.

Quick answer

A CRM MCP server is a CRM exposed through the Model Context Protocol (MCP), so MCP-compatible AI clients such as Claude and ChatGPT can read and act on it through one standard connection. Workspace369 has one. It covers clients, proposals and contracts, invoices and payments, projects, tasks and time, the calendar, the inbox and automations. Sends wait for your approval.

What MCP actually is

Also readWorkspace369 MCP integration

The Model Context Protocol is an open standard that lets AI clients connect to external tools and data sources through a shared interface. Instead of every AI vendor building a custom plugin for every app, an app publishes one MCP server and every compatible AI client can use it.

For a CRM, that is the difference between pasting your data into the chat and letting the chat work with your workspace. The Workspace369 MCP integration page lists what a connector can do and what it holds back. This guide stays with the concepts.

To see everything the Workspace369 MCP server can do, including which actions wait for your approval, read the MCP server feature page.

Where MCP differs from a built-in assistant

Most CRMs approach AI in one of two ways:

  • A built-in assistant that only works inside their app.
  • A connector that lets the AI client you already use reach your records.

A connector keeps you in the AI client you already use. Several client-work tools now offer one, including HoneyBook, Bonsai and Moxie. On October 27, 2026, Moxie's help center limited its MCP server (beta) to Pro and Teams workspaces, Bonsai's MCP page said it needs a paid plan, and HoneyBook's August 19, 2026 announcement did not name a plan. What differs between them is the detail: which plans include it, what it can write, and what it holds back for a person to approve.

What you can do through the Workspace369 MCP server

  • Look up clients and open their records
  • Draft proposals and contracts, and edit proposal sections and design
  • Draft invoices, look up payments and record them
  • Create projects and tasks, add notes and comments, and log time
  • Check availability and create or change calendar events
  • Search messages and read client requests
  • List and test workflow automations, read their runs, and switch them off

Ask which invoices are past due and get the list with the clients attached. Ask for an invoice for finished work and a draft appears in your workspace, ready for you to review.

Some things wait for you. Sending an invoice, proposal, contract or message, and a few other actions are held until you approve them. Not every part of the app is available through MCP: building or turning on a workflow, billing and plan changes, and team roles and permissions stay in the app.

A CRM conversation becomes a checked task as a person organizes client documents beside a calendar.

Which AI clients work with it

Claude and ChatGPT both connect to Workspace369, and the integration page also lists Grok, Cursor and Windsurf. Other clients that support MCP over OAuth should be able to connect too.

How to connect

  1. Open your AI client's connector or MCP settings.
  2. Add the Workspace369 MCP server.
  3. Sign in with your Workspace369 account, pick the workspace and choose what the connection may do.
  4. Ask for something real, such as a client lookup or an overdue-invoice list.

The connector is included on every plan, but it is off until a workspace admin turns it on. Each tool call draws from your plan's monthly usage.

Where to go next

The Workspace369 MCP integration page has the full list of what a connector can do and what waits for approval. The MCP prompts guide has examples to start from.

FAQ

What is a CRM MCP server?

A CRM MCP server exposes a CRM through the Model Context Protocol, so AI clients like Claude and ChatGPT can read records and take actions, such as drafting an invoice, through a standard connection instead of a custom plugin.#

Which AI clients can connect to Workspace369 through MCP?

Claude and ChatGPT, plus any other client that supports MCP over OAuth. Add the Workspace369 server in the client, sign in, choose what the connection may do, and ask in plain language.#

Can an AI actually change things in Workspace369, or only read data?

Both. A connector can create and update clients, draft proposals and invoices, record payments, manage projects, tasks and time, and change calendar events. Sending an invoice, proposal, contract or message waits for your approval.#

Is Workspace369 the only CRM with an MCP server?

No. HoneyBook, Bonsai and Moxie offer AI connectors too; Moxie documents its MCP server for Pro and Teams workspaces, and Bonsai's needs a paid plan. On Workspace369 the MCP server is included on every plan, including Cadet (an admin turns it on), and you choose each connection's permissions when you authorize it.#

Does a CRM MCP connector cost extra?

On Workspace369 it is included on every plan and each tool call draws from the plan's monthly AI usage allowance. Other vendors gate it by plan, so check before you rely on it.#
