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](/overview/intangible-mcp/connect-claude-desktop.md), [Claude Code](/overview/intangible-mcp/connect-claude-code.md), and [ChatGPT](/overview/intangible-mcp/connect-chatgpt.md). 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](/overview/concepts/credits-and-tokens.md) and [Sign up and set up](/overview/get-started/sign-up-and-set-up.md). 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](https://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](/overview/intangible-mcp/what-your-agent-can-do.md). ## 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. ## Related * [MCP (Model Context Protocol)](/overview/intangible-mcp.md) * [Connect Claude Desktop](/overview/intangible-mcp/connect-claude-desktop.md) * [Connect Claude Code](/overview/intangible-mcp/connect-claude-code.md) * [Connect ChatGPT](/overview/intangible-mcp/connect-chatgpt.md) *Last updated 7 August 2026.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.intangible.ai/overview/intangible-mcp/troubleshooting-and-faq.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
