# MCP dynamic authentication

MCP dynamic authentication is now generally available.

With dynamic authentication, MCP tools run using end-user credentials rather than shared service accounts. Actions execute with each user's own permissions and are fully traceable back to that person.

**What's included**

* Tools can run using user-provided authentication instead of shared service accounts — end users authenticate with their own credentials and actions execute with their permissions
* Authentication Management tab — manage all authentications used by your MCP tools, set their types, and view where they're used
* User access management through an allowlist — control who can execute tools on your MCP server
* Monitor tab showing usage, connected users, and tool execution activity

**Why it matters**

* Better security — users can only do what their permissions allow
* Full auditability — every action traces back to a specific user
* Production-ready observability — see who's using what and when
