Troubleshooting and FAQ
Fixes for connecting an AI agent to Intangible's Model Context Protocol (MCP) server: the server URL, supported clients, sign-in problems, and empty-scene issues.
Common questions and fixes for connecting an AI agent to Intangible's Model Context Protocol (MCP) server. Each heading below is a single symptom or question.
What is the Intangible MCP server URL?
The Intangible MCP server URL is https://mcp.intangible.ai/mcp. It is a hosted remote server with OAuth sign-in, so there is nothing to install and nothing to run on your machine.
Which AI agents can connect to Intangible over MCP?
Any MCP-capable client can connect to Intangible. Step-by-step pages cover Claude Desktop, Claude Code, and ChatGPT. Other clients connect with the same server URL and OAuth sign-in.
Do I need a paid Intangible plan to use MCP?
You need an Intangible account to use the MCP server. Some Studio actions cost credits or require a paid tier, the same as when you work by hand – see Credits and tokens and Sign up and set up. Your agent client may also have its own plan requirement for connectors.
The Intangible viewport stays empty after a prompt
If nothing appears in the Studio viewport after a prompt, the agent has no live scene to edit or is still searching. First, make sure a Studio tab is open – open a project at studio.intangible.ai, or ask the agent to create one. Second, give it a moment: on larger scenes the viewport can sit empty for a few seconds while the agent searches for assets.
The agent reports no open Intangible project or scene
If the agent says there is no open project or scene, ask it to create one first: "Create a new project and scene, then start building." The agent can also list your existing projects and open one.
Several Intangible Studio tabs are open at once
If you have more than one Studio tab open, the agent may edit a scene you are not looking at. Keep one project tab open at a time and close the extras.
Signing in to the Intangible MCP server fails
If the connection or sign-in fails, re-run your client's authentication. In Claude Code, run /mcp, select intangible, and sign in again. In Claude Desktop or ChatGPT, remove and re-add the Intangible connector, then approve access in the browser window. Confirm you are signed in to the right Intangible account.
Objects land in the wrong place
Objects landing close but not exact is expected. The agent gets a scene about 80 percent of the way, then hands it back for final positioning, which is faster by hand than another prompt. See What your agent can do.
Does the Intangible MCP server run offline or on localhost?
No. The Intangible MCP server is hosted at https://mcp.intangible.ai/mcp. Your agent reaches it over the network and signs in with OAuth. There is no offline or localhost mode.
How do I remove the Intangible connector?
Remove the connector in your client. In Claude Code, run claude mcp remove intangible. In Claude Desktop and ChatGPT, delete the Intangible connector from the connector settings.
