What can the Close MCP server do?
It gives an AI client access to your Close data at one of three levels, from read-only up to delete. The scope you grant is the control.
The short answer
- Close MCP connects an AI client such as Claude, ChatGPT or Cursor to your Close CRM data through a remote server at mcp.close.com/mcp.
- Close MCP access comes in three scopes: mcp.read is read-only, mcp.write_safe reads and writes, and mcp.write_destructive can also delete data, per Close's help centre in September 2026.
- Close MCP signs in with OAuth 2.0, including dynamic client registration, or with an API key sent alongside a scope header.
- For most Close teams the right starting scope is mcp.read, moving to mcp.write_safe only once prompts behave as expected.
How the Close MCP server works
Close calls its MCP server a standard interface that lets any compatible AI model or agent reach your Close data. In practice, you add the server to your AI client, sign in, and ask for what you need in plain words. The client turns your request into calls against Close.
You've got two ways to sign in. OAuth is the everyday route for Claude and ChatGPT. An API key suits scripts and agent frameworks: you send it in a Close-API-Key header along with a Close-Scope header that names the access level. That second header is the part to get right.

Which Close scope to grant
Start read-only. With mcp.read, your AI client can answer questions about leads and pipeline without touching a record. That covers a lot of daily use: a morning summary, a list of deals gone quiet, a draft reply you paste in yourself.
Move to mcp.write_safe when you want the client to log notes or update fields. Keep mcp.write_destructive for a named admin task, then revoke it. A delete prompt that matches more records than you meant is the classic way a test run turns into a restore.
SalesCrew scopes access on a different axis. Each person holds their own MCP token, limited by channel, Upwork profile and area, the same way the UI limits them. Across 140+ tools, every call lands in an audit log, and any external send waits in one approval queue by default. Seats are unlimited on every tier, so each teammate can have a token of their own.

Questions
- Does Close CRM have an MCP server?
- Yes. Close runs a remote MCP server at mcp.close.com/mcp over streamable HTTP, per its help centre in September 2026. You connect it from Claude, ChatGPT, Cursor, VS Code or an n8n AI Agent node, and sign in with OAuth or an API key.
- What is the difference between mcp.write_safe and mcp.write_destructive?
- Delete rights. Close's mcp.write_safe scope lets the AI client read and write data, while mcp.write_destructive adds deleting data in the Close organization. A third scope, mcp.read, is read-only. Most sales workflows never need the destructive one.
- Do I need a paid Claude plan to use Close MCP?
- For the connector, yes. Close's docs say Claude's Connectors library, which lists Close, needs a paid Claude plan. Claude Code setup works on any plan, and Claude Desktop has its own connection options for free users.
- How do I connect Close to ChatGPT?
- Use the official Close app in ChatGPT. Close's MCP docs list it alongside setup steps for Claude, Cursor and VS Code, as of September 2026. You sign in to Close from ChatGPT with OAuth, and the scope you grant decides what ChatGPT can change.
