Question

Custom MCP server no tools in agent/make

I’ve connected a custom MCP server connector and the Connect goes through, manage shows correct list of tools and I can set whether each needs permission to use or not. But when I try to use the connector, I get back that Figma fails to load any tools. I’ve used the same server with Claude and Codex and works there. Any ideas what could be the problem? Is there any special steps to add the connecter to session (I’ve used the +-button). Here’s what Figma AI says about the connector.

The OINO.cloud server has no listed resources. MCP servers expose tools separately from resources — I can only list resources via my available tools, not enumerate the tool definitions directly.

PS. talking about the browser-Figma.

Another version of the error when asked to use tool list_tables that exists and is approved to use:

 

The MCP server has no listed resources, but may still expose tools. Unfortunately, I can only call MCP tools that are explicitly registered in my tool list — the OINO.cloud server's list_tables tool isn't available in my current tool set.

To use it, the server would need to be configured so its tools appear in my tool list. Could you check that the OINO.cloud MCP server is properly connected and its tools are enabled in your Claude Code settings?

Hey, ​@pragmatta - thanks for your post! Hopefully this hasn’t been too confusing for you. 

 

Is there are reason you’re using a custom connector rather than the supported plugins/connectors for supported clients? From your reply, you mention Claude Code which has an official plugin you can use. To install the Anthropic plugin, use this command:

claude plugin install figma@claude-plugins-official

 

You can also manually set up the plugin, though the above command is the preferred method. Let me know if I’ve misunderstood what you are trying to do or if you have trouble with the official plugin.

It’s actually a connector we’re developing and trying to test interoperability with Figma, hopefully allowing Figma to setup data model and auth and make pilotable apps. And it kinda seems to work, i.e. you can connect and list all the tools and set permissions on each tool, but in session Figma can’t see the tools. And this actually how Claude etc. that you first setup a connecter at the account level and then you need to connect it to a project/session (so that all connecters are not automatically available in all sessions), but can’t figure out how to connect it (besides using the +-button which does not help).

Oh, I see what you mean - thanks for clarifying! There is the official Figma connector for Claude, though it’s more meant to take your Figma designs and let Claude build off of those locally rather than create something within Figma as the plugin does; it makes sense you might try to make your own that provides more tools. I can understand preferring a connector over the plugin if you’re looking to implement this across an org, too. If that’s a real driver for you, you could contact Anthropic and ask them to install the plugin for all users in your org.
