How to Use the FreeClimb MCP in Cursor

Q: How do I add the FreeClimb MCP Server to my Cursor editor?

Add the server details to your .cursor/mcp.json file in your project root. Once configured, Cursor's Agent mode automatically gains access to MCP tools like makecall and sendsms.

Q: Does FreeClimb work with Cursor's multi-file editing?

Yes. Cursor can read your workspace files and use getapplicationdetails to configure multiple webhooks across different files simultaneously, keeping your routing logic aligned.

Q: How do I check my developer account balance?

Ask the agent in Cursor to run getaccountstatus. It will output your current API balance directly into your chat console.

Let Cursor write, test, and run FreeClimb voice and SMS workflows directly within your codebase.

Perplexity

Live code generation with real API data

This FreeClimb MCP Server enables Cursor to fetch real-time telephony data using `get_call_details` while you write code. Your agent pulls actual API responses instead of static mocks, letting you build reliable voice applications faster. When you toggle Agent mode in Cursor, the editor uses `list_calls` to inspect your live traffic. This means you write integration tests against real call histories without leaving your active file.

Active debugging of SMS workflows

Debugging message delivery requires real logs, which Cursor accesses via `list_sms_messages` and `get_sms_details`. Your agent reads the exact error codes from failed texts to fix your webhook handlers on the fly. You don't have to copy-paste error payloads from an external terminal. Cursor inspects the API responses directly, letting you patch your code and test the fix by triggering `send_sms` from the chat panel.

Telephony inventory management

The MCP Server exposes your active phone number inventory to Cursor using `list_my_numbers` and `list_applications`. Your agent maps incoming webhooks to the correct local dev server ports during development. If you need a new testing number, you can search and buy one using `list_buyable_numbers` right inside the editor. The agent updates your local `.env` file with the new number automatically.
