Bitbybit CAD is an MCP server with 7 tools an agent can call, among them describe, fetch, get_examples. It answers at https://mcp.bitbybit.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
Bitbybit 3D parametric CAD API, version-exact, for coding agents: search, describe, examples, guide
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
describe | The exact contract of one member by dotted path, for example occt.shapes.solid.createBox: signature, every parameter with its type, default and range, the return type, the documentation, examples and where it runs. Answers are for the API v Inputs: path, version |
fetch | Fetches the full documentation of one Bitbybit API member by id (a dotted path returned by search) as text, with its title, url and metadata. Inputs: id |
get_examples | Working TypeScript examples for a member path, for a namespace, or for a topic given as keywords. Each example names the member it belongs to and links its reference page. Examples are written for the API version the server holds. Inputs: path, topic, engine, limit, version |
get_guide | Sections of the public guides: building with Bitbybit (what runs in the browser, on a server, on a lightweight backend, and what needs CAD Cloud), writing geometry with the kernels (which kernel to use, the order to build a part in, choosin Inputs: topic |
list_namespace | The members one level below a namespace path, for example occt.shapes, each with its kind and summary. Without a path, the top-level namespaces. Use it to discover what exists before searching for details. Inputs: path, version |
search | Searches the Bitbybit API documentation and returns a list of results with id, title and url. Each id is a dotted API path that fetch accepts. Inputs: query |
search_api | Find Bitbybit API members (methods, namespaces, cloud operations) by keywords, for example "box solid" or "fillet edges". Returns dotted paths with a one-line summary, the tier (oss on npm, platform-pro only at bitbybit.dev, cloud-pro only Inputs: query, engine, limit, version |

Yes. It is published by bitbybit.dev and served from mcp.bitbybit.dev, the vendor's own domain: https://mcp.bitbybit.dev/mcp.
7, as returned by the server's own tools/list on 12 November 2026: describe, fetch, get_examples, get_guide, list_namespace, search, search_api.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.bitbybit.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 20 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
