NEON MCP Server Got Undefined 'Org_id' error when Listing Project
I ask my Neon MCP in Claude Desktop App to list all the projects, and it gives me "Cannot read properties of undefined (reading 'org_id')" error. Seems like the remote API got changed but the Neon MCP server code haven't updated yet.

I'm also seeing this bug
I'm a developer at Portia AI (https://www.portialabs.ai/) - we're building an MCP integration to support 1st party MCP remote servers like Neon.
The issue I'm seeing with Neon is that the argument schema for the
listProjects tool does not require the params field, but if left out (i.e. calling with no arguments) the MCP server returns an error, exactly as OP describes above.
It'd be helpful for integrations if the schemas described the required fields accurately! We'd love to be able to provide Neon tools to our end-usersPortia AI

Thanks for reporting! Checking now
@Sam @birdnest - what version of the MCP server are you using - remote or local? Just tried to replicate with remote MCP server and I'm able to list my projects. Will try with local MCP server now and also shared this thread with the team.
Local MCP also works for me. Can you share the MCP config?
Team is looking into it! 🙏

This should be fixed now and published to both remote server and NPM Package. It issue seem to be with tool arguments schema.
