Connecting to the MCP agent (new feature) not working

when I try to connect claude code I get this error:

Your account was authorized, but no MCP server was found at the provided URL, or your account doesn’t have access to it. Check the server URL or your access, then try again. If this persists, share this reference with support: “ofid_5f597643dec86a9f”

Hi @chrisbehnke,

Thank you for reporting this!

We found connection attempts to an MCP associated with your account where the Authorization header text was included in the server URL. In the Claude Code command, the server URL is the web address beginning with https://. The Authorization header is a separate part of the command that begins with --header. Please do not include that part in the URL. Those attempts returned a “server not found” response. Later requests reached the MCP server, but we can’t tell whether they came from your Claude Code setup.

Could you share the exact Claude Code command or MCP configuration you used? Please replace the bearer token with [REDACTED] before posting it.

Thanks! I was able to authenticate, BUT now I’m getting an error of “This connector has no tools available”

so I’m not sure how to “enable them”

Hi @chrisbehnke,

Our Pickaxe MCP for managing your workspaces works with Claude’s connector by simply searching for Pickaxe in the Discover tab, or by adding https://mcp.pickaxe.co as a custom connector and logging in via OAuth.

However, using the deployment/portal MCP with Claude’s connector doesn’t work at the moment because it doesn’t allow you to add Authorization headers. When you take a look at Get started with custom connectors using remote MCP | Claude Help Center, they’re saying “Request header authentication is in beta and available to a limited set of organizations”.

Though, it does work with the Claude Code CLI when configured as instructed (see the image below for an example) or use another AI app as an alternative.
