# Read-only modes to start with: Top MCP Servers

**Answer in brief:** Several makers offer a way to connect that can only read. Start there, and allow writes once the agent has behaved.


## A read-only address

Linear runs a second address, `https://mcp.linear.app/mcp/readonly`, that can only read.[1]

## One project, read only

Supabase lets you scope its server to one project and make it read only. It warns that connecting a model to your projects carries security risks.[2]

## Narrow access on GitHub

GitHub's server acts with your GitHub access. Grant it only the repositories the task needs, and keep its toolsets narrow.

- [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.
- [Servers that move money, files or messages](/servers-that-write/): Reading carries little risk. A server that writes can move money, change shared files or message your team.
- [Conecto and Top MCP Servers](/conecto/): 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.
