Cloudron Forum

Hi @james,

Thanks for the super quick response on adding those flags, really appreciate it.

Just wanted to give you a quick update. I actually managed to get things working via a local workaround - running the Penpot MCP server on my own machine and bridging it to the canvas using a browser plugin.

While trying to get the remote connection working earlier, though, I noticed that hitting https://[domain]/mcp/stream returns a standard HTML webpage instead of the expected SSE stream (text/event-stream). From what I can tell, I think Penpot’s MCP server might actually run as a separate standalone service or container, rather than being built directly into the core backend.

If that is the case, I think the Cloudron package might eventually need to bundle that extra container and map the Nginx routing for the /mcp/ paths to get remote connections working properly.

There's no rush since my local setup is doing fine, but I figured I'd pass this along in case it saves you some debugging time.

I created a /app/data/env.sh file and tried adding the following line:

export PENPOT_FLAGS="enable-registration enable-login-with-password enable-access-tokens enable-mcp"

After saving the file and completely restarting the app via the Cloudron dashboard, the "Integrations" and "Access Tokens" UI elements still do not appear in the Penpot account settings.

My assumption was that the Cloudron deployment's internal startup script dynamically generates or overrides the PENPOT_FLAGS variable (perhaps to ensure SMTP or OIDC settings stay intact) and is ignoring the manual export in env.sh.

If there is a specific syntax I should be using in env.sh to append custom flags without them getting overwritten by the system, please let me know! Otherwise, having a supported way to inject flags like EXTRA_PENPOT_FLAGS would be really helpful.

Hi everyone,

I am trying to set up the new official Penpot MCP (Model Context Protocol) server to integrate my self-hosted Penpot instance with local AI coding clients like Cursor and Claude Desktop.

Currently, this is impossible on the Cloudron deployment because the necessary UI elements ("Integrations" and "Access Tokens" in the account settings) are hidden behind Penpot feature flags that are not enabled in the Cloudron package.

Because Cloudron dynamically constructs PENPOT_FLAGS on startup, manually editing env.sh to add these flags gets ignored/overwritten.

Could we get one of the following implemented in the next package update?

Option A (Ideal): Enable the enable-mcp and enable-access-tokens flags by default in the app's startup script, as these are becoming standard features for modern AI workflows.

Option B (Flexible): Expose an EXTRA_PENPOT_FLAGS variable in env.sh that gets appended to the main string on startup. This would allow advanced users to opt-in to new Penpot backend features without waiting for package updates.

Thanks for maintaining this package! Let me know if there is a temporary workaround I can use in the meantime.
