Nothing serious here today

Today is the operative word: we check Cbm every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

calculate
calculate_cbm
Calculate total shipment volume (CBM / cubic metres and CFT / cubic feet), total weight, and how that cargo fits into standard shipping containers (20ft Standard, 40ft Standard, 40ft High Cube). Use this whenever someone asks how much space a shipment takes, how many cubic metres or CBM their boxes / pallets / cartons add up to, whether cargo will fit in a container, what container size they need, or how full a container will be. Accepts a list of items with length, width, height, weight and quantity in metric (cm, kg) or imperial (in, lb) units; returns total CBM, CFT, total weight, and per-container fill percentage with an overload flag.
container
get_container_dimensions
Interior dimensions, volume, floor area and maximum payload for 47 shipping containers, truck trailers, rail wagons and air ULDs. Use this when someone asks for the internal or interior dimensions, cubic capacity, floor area, payload or weight limit of a container or trailer — 20ft, 40ft, 40ft High Cube, 45ft, reefer, open top, flat rack, 53ft dry van, curtainsider, boxcar, LD-3, PMC and more. Called with no arguments (optionally filtered by mode) it lists the whole catalog with the slug for each vessel.
how
how_many_pallets_fit
How many pallets fit in a given shipping container, truck trailer, rail wagon or air ULD. Use this whenever someone asks how many pallets (Euro 1200x800, standard 1200x1000, or US GMA 48x40) fit in a 20ft, 40ft, 40ft High Cube, 45ft, 53ft trailer or any other vessel. Returns the best single-layer floor count with pallets turned to their best orientation — a solved pallet-loading result, not length divided by length, so a 20ft holds 11 Euro pallets and a 40ft holds 25 — plus the double-stacked count with the load height that allows it, and how many the payload allows, which is what decides whether weight or floor space runs out first.
plan
plan_cargo_load
Plan how one cargo size loads into a shipping container, truck trailer or rail wagon. Use this when someone asks how many of their boxes, cartons, crates or pallets (of a given size, and optionally weight) fit in a 20ft, 40ft, 40ft High Cube, 45ft, 53ft dry van, curtainsider or other vehicle, how many containers or trucks a quantity needs, or whether weight or space limits the load. Returns units per floor layer (mixed orientations), layers by interior height, units per load, whether space or payload binds, loads needed, utilisation, and a link to the same plan drawn on the web. One size per call; for several sizes, call once per size.

Cbm — questions

Answers built from our own checks of this server.

What can Cbm do?
It exposes 4 tools, read directly from the server on our last check. Among them: calculate_cbm, get_container_dimensions, how_many_pallets_fit, plan_cargo_load. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Cbm working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 94 ms. The bar chart above shows every period we have measured.
How do I connect Cbm?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Cbm need an API key?
No. Cbm completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cbm?
It answers our handshake in 94 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
