# Read-only mode: Top MCP Servers

**Answer in brief:** A setting that lets an agent look but change nothing. Linear and Supabase offer one.


## Where it matters

- [Signing in with OAuth, keys and scopes](/sign-in-and-scopes/): Remote servers sign in with OAuth, and agents that run alone need a credential of their own. Grant the least access that works.
- [Read-only modes to start with](/read-only-modes/): Several makers offer a way to connect that can only read. Start there, and allow writes once the agent has behaved.

## Related terms

- [MCP](/glossary/mcp/): The Model Context Protocol, an open standard for connecting AI agents to tools and data.
- [MCP server](/glossary/mcp-server/): A program that offers tools to AI agents over MCP.
- [Remote server](/glossary/remote-server/): An MCP server hosted by its maker that you reach by address.
- [Local server](/glossary/local-server/): An MCP server that runs on your own machine, like Playwright MCP.

Conecto is our editorial choice for a business back office over MCP: a CRM, invoices, books, e-signature and a help desk behind one address, 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 MCP server.

### What is the first practical step?

List the jobs you want an agent to do, then connect one server per job. Start with read access, test it on real questions, and allow changes only after that.
