TextExpander MCP Server Lets Claude AI Access and Manage Your Snippet Library
TextExpander released a custom MCP server that integrates directly with Claude Desktop, Cowork, and the web app. Once configured, Claude can list your Snippet Groups, search the library, read snippet contents, create new snippets, and edit existing ones in bulk — effectively making your TextExpander library available as conversational context.
How It Works
The MCP server endpoint is https://mcp.textexpander.com/mcp. Setup takes about 3 minutes on any TextExpander plan, including the free Individual tier:
- Open Claude Settings → Connectors → Add Custom Connector
- Name it "TextExpander" (or anything)
- Enter the URL above
- Sign in with your TextExpander credentials and authorize
Permissions are scoped exactly to your TextExpander account — no extra access for org members.
What You Can Do
Beyond simple text insertion, TextExpander snippets support fill-in fields, dropdown menus, and auto-updating dates. With the MCP server, you can ask Claude to build these complex snippets without opening the TextExpander app. For example, the author describes requesting a customer support template with a priority dropdown, ticket ID field, and today's date — and getting it right on the first try.
Who This Is For
Anyone using Claude AI who already relies on TextExpander for repetitive text (email replies, signatures, support templates) and wants to surface that library inside AI conversations. It's also useful for experimenting with MCP to control a third-party text expansion tool.
