This is the Bitbybit CAD MCP: it documents the Bitbybit 3D CAD API (OpenCascade, JSCAD and Manifold kernels, with Babylon.js, three.js and PlayCanvas renderers) for one exact version. Always describe a member before using it: names, parameters and defaults come from the index, not from memory. Tiers matter: oss members are in the MIT npm packages and run anywhere; platform-pro members exist only inside bitbybit.dev; cloud-pro members run only on Bitbybit CAD Cloud with an API key. When asked where geometry should run, read get_guide("integrate") first: the packages alone are the default, and…

- Is bitbybit live?
- Yes — it answered the hub's last check (checked 3h ago). It answered 99% of checks over the last 30 days.
- Is bitbybit free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does bitbybit have?
- 7 tools: describe, search_api, get_examples, fetch, search, list_namespace, get_guide.
- Is bitbybit safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
list_namespace reads open 20h ago
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "path": { "type": "string", "maxLength": 256, "description": "A namespace path such as occt or occt.shapes; omit for the top level" }, "version": { "type": "string", "description": "The API version to list; omit for the version the server holds" } } }arguments 15 linesget_guide reads open 20h ago
Sections of the public guide on building with Bitbybit: what runs in the browser, on a server, on a lightweight backend, and what needs CAD Cloud. Without a topic it lists the sections. Read "integrate" before recommending where geometry should run: the npm packages are the default, and CAD Cloud is for algorithms that exist only there or compute the caller cannot provide.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "topic": { "type": "string", "maxLength": 128, "description": "A section id or a short name such as integrate, browser, backend, server-side, pro, start; omit to list the sections" } } }arguments 11 linesdescribe reads unknown 3h ago
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 version the server holds. An unknown path is reported as not found together with the nearest existing paths; nothing is guessed.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "path" ], "properties": { "path": { "type": "string", "maxLength": 256, "minLength": 1, "description": "The dotted path of the member, for example occt.shapes.solid.createBox" }, "version": { "type": "string", "description": "The API version to describe; omit for the version the server holds" } } }arguments 19 linessearch_api reads unknown 12h ago
Find Bitbybit API members (methods, namespaces, cloud operations) by keywords, for example "box solid" or "fillet edges". Returns dotted paths with a one-line summary, the tier (oss on npm, platform-pro only at bitbybit.dev, cloud-pro only on CAD Cloud) and the engines each is published for. Call describe with a path before writing code that uses it.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "query" ], "properties": { "limit": { "type": "integer", "maximum": 50, "minimum": 1, "description": "How many results, 10 by default" }, "query": { "type": "string", "maxLength": 200, "minLength": 1, "description": "Keywords, a phrase, or a partial dotted path" }, "engine": { "enum": [ "babylonjs", "threejs", "playcanvas" ], "type": "string", "description": "Only members published for this engine, plus the cloud operations, which run on CAD Cloud rather than in an engine; omit for every engine" }, "version": { "type": "string", "description": "The API version to search; omit for the version the server holds" } } }arguments 34 linesget_examples reads unknown 20h ago
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "path": { "type": "string", "maxLength": 256, "description": "A member or namespace path, for example occt.shapes.solid.createBox or occt.fillets" }, "limit": { "type": "integer", "maximum": 20, "minimum": 1, "description": "How many examples, 5 by default" }, "topic": { "type": "string", "maxLength": 200, "description": "Keywords to find examples by, when no path is known" }, "engine": { "enum": [ "babylonjs", "threejs", "playcanvas" ], "type": "string", "description": "Prefer members published for this engine when searching by topic" }, "version": { "type": "string", "description": "The API version; omit for the version the server holds" } } }arguments 35 linesfetch reads unknown 12h ago
Fetches the full documentation of one Bitbybit API member by id (a dotted path returned by search) as text, with its title, url and metadata.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "id" ], "properties": { "id": { "type": "string", "maxLength": 256, "minLength": 1, "description": "A dotted API path returned by search" } } }arguments 15 linessearch reads unknown 12h ago
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "query" ], "properties": { "query": { "type": "string", "maxLength": 200, "minLength": 1, "description": "Search terms" } } }arguments 15 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id6294e90625b229b3.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/6294e90625b229b3/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
