Hi all,
I’ve been trying for the past two days to get the mcp-hubspot app installed using Smithery CLI, and I keep running into issues that are blocking progress. Here’s a breakdown of what I’ve encountered so far in case anyone else has been through this—or better yet, found a fix.
Latest Error:
When I run the following command: npx -y @smithery/cli@latest install mcp-hubspot --client claude
I get this:: 
Failed to install mcp-hubspot
Error: Package resolution failed with status 500: Internal server error
This seems to be a backend issue—possibly with the package registry or Smithery service—but I haven’t found any documentation or status updates confirming this.
Other Issues Faced Previously
- Smithery CLI glitches
The install command doesn’t always resolve dependencies smoothly, especially when scoped packages or custom clients like --client claude are involved.
- HubSpot CMS compatibility issues
Even when I managed to install other packages, I ran into version mismatches or incomplete configurations that required manually editing theme.json, fields.json, and other project scaffolding files.
- Lack of documentation
There’s very little documentation or step-by-step guidance for MCP-related packages or Smithery workflows beyond simple use cases. Advanced setups with custom clients or integrations (e.g., Claude, GPTs, etc.) are totally absent.
- Ambiguous errors from CLI
Most CLI errors aren’t descriptive and don’t provide actionable feedback, making troubleshooting extremely difficult. Even adding --debug doesn’t help much beyond a stack trace.
Ask:
Has anyone in the community successfully installed mcp-hubspot using Smithery CLI recently? If so:
- What command did you use?
- Which Node/npm version are you on?
- Any tweaks to .env or file structure?
- Did you face and resolve this 500 error?
I’d really appreciate any insights. It’s a promising setup, but these issues make onboarding extremely frustrating.
Thanks in advance,
