Unable to add New Relic MCP to Automations

[Kyle_Holgate]

When trying to set up a New Relic MCP connection for automations, I simply get this error that says “connection failed”. I’m able to use the same exact connection settings (URL and api-key header) in Cursor IDE and it works fine.

• Bug happens only in Automations
• When attempting to connect to New Relic MCP with details like the below, it gives a Connection Failed error

"url": "https://mcp.newrelic.com/mcp/",

"headers": {

"api-key": "NRAK-YOUR-API-KEY-HERE"

}

• Steps to reproduce - create a new MCP connection to New Relic for Automations, add a valid api-key header, and attempt to add it to a new automation
• Expected behavior is it connects

I’m also experiencing the same issue for the LogFire MCP. Even through the oauth version, it is not working. It is saying that there is a missing refresh token.

Hey, this is a known issue. MCP connections via Automations are unstable right now. We’re seeing similar reports with other providers like Sentry, Datadog, and LogFire.

The team is aware. There’s no ETA yet, but your reports help us prioritize.

@c2keesey same situation with LogFire, we’re tracking it.

I’ll post here when there are updates.
