# Announcing MCP Authentication: secure your MCP servers with PropelAuth

[**Streamlit**](https://streamlit.io/?ref=propelauth.com) is an open-source Python framework that makes it incredibly easy for data scientists and machine learning engineers to create interactive web applications from their existing Python scripts. Think of it as a magic wand that transforms your Python code into a beautiful web app - even if your CSS skills are limited.

And while Streamlit is known for its ease of use, protecting a Streamlit app with Authentication and Authorization is limited. That’s why we’re happy to announce our support for Streamlit, complete with all that makes [**PropelAuth**](/content/?ref=propelauth.com) great - organizations, role based access control, multiple login methods, and more.

## Haven’t we done this before?

If this all seems familiar, you’re right! About a year ago we announced a previous integration with Streamlit. While this integration allowed many of our Python-loving customers to protect their Streamlit apps, we knew that we could make our integration simpler, more straightforward, and even more powerful.

This time around, we’re using Streamlit’s new [**OpenID Connect (OIDC) support**](https://docs.streamlit.io/develop/concepts/connections/authentication?ref=propelauth.mymidnight.blog) to integrate with PropelAuth. Now, integrating PropelAuth only takes a few minutes and only takes a few lines of code:

```python
if st.experimental_user.is_logged_in:
    user = auth.get_user(st.experimental_user.sub)
    if user:
        st.write(user)
else:
    st.login()
```

## So what’s different?

This time around we wanted to focus on one of PropelAuth’s most powerful features - Role Based Access Control (RBAC). Combining the ease of use of both Streamlit and PropelAuth, protecting resources based on a user’s role and permissions within an organization is now simpler than ever.

```python
def return_org_name(org):
    return org.org_name

if st.experimental_user.is_logged_in:
    user = auth.get_user(st.experimental_user.sub)
    org = st.selectbox(
	    "Select an organization",
	    user.get_orgs(),
	    format_func=return_org_name
	  )
    permission_to_check = "can_view_protected_data"
    if org and org.user_has_permission(permission_to_check):
        st.write(f"You can view this data for org {org.org_name}")
    else:
        st.write("You do not have the necessary permission to view this data.")
```

## Let’s get going!

Eager to get started? Whether you’re looking for organization management, MFA, SAML, or user impersonation, getting your Streamlit app up and running with PropelAuth is quick and easy.
