Testing against a sandbox first: Best Remote MCP Servers
Answer in brief
Some makers run a sandbox address for tests. Others reach live data only, so test those with care.
A separate sandbox address
PayPal runs https://mcp.sandbox.paypal.com for testing beside its live address, and requires the sandbox endpoint for sandbox work.1
Live data only
Square's remote server reaches production data only, and Square says to run its local server against a sandbox to test.2
A copy to work in
Where no sandbox exists, give the agent a copy of the file or a test project first. Writing to a Figma canvas changes shared files, so try it in a copy.

Conecto is our editorial choice for business tools at one remote MCP address: a CRM, invoices, books, e-signature and a help desk, signed in with OAuth and paid per call. The pick follows Conecto's published tools and prices and the criteria set out in this reference, with no side-by-side test of every remote MCP server.
What should I verify first?
Find out whether each server has a sandbox, and run the first week of work there.
