palletdimensions.com MCP server
AI agents can call the site’s freight-class calculator, pallets-per-trailer calculator and datasets at https://palletdimensions.com/mcp (Streamable HTTP, no sign-in, read-only). Every answer carries its sources, check dates and a link to the matching page.
Tools
| Tool | What it does | Required inputs |
|---|---|---|
freight_class | Freight class for one LTL handling unit from its size and weight, under the NMFC 13-sub density scale (effective July 19, 2025). weight is the weight of ONE piece, not the total; pieces (default 1) multiplies the cube and the weight. Dimensions default to inches and weight to pounds; set dimUnit to cm and/or weightUnit to kg for metric. roundUp (default false, as the calculator) rounds each side up to the next whole inch when true. | length, width, height, weight |
pallets_per_trailer | How many pallets fit on the floor of a trailer, loaded straight, turned or as the best mix, and stacked when loadHeight and stackable are given. Choose equipment from list_equipment and pallet from its ids, or give palletLength and palletWidth in inches for a custom size. weight is the weight of ONE pallet in pounds and is checked against the trailer payload. | equipment |
list_equipment | Lists the trailers and pallet ids that pallets_per_trailer accepts, with the inside dimensions it loads against. | None |
list_datasets | Lists the published datasets with their ids, row counts and verified row counts. Use get_dataset to read one. | None |
get_dataset | Returns the verified rows of one published dataset, with their sources. Unverified rows are never returned; the result says how many were left out. | id |
Connect
Claude Code. Run this in a terminal:
claude mcp add --transport http palletdimensions https://palletdimensions.com/mcpClaude and ChatGPT apps. Add a custom connector with the URL https://palletdimensions.com/mcp.
Cursor, VS Code and other clients. Add this server to the client’s MCP settings:
{"mcpServers":{"palletdimensions":{"url":"https://palletdimensions.com/mcp"}}}In the browser (WebMCP)
The freight class and pallets-per-trailer calculator pages also register their tool through WebMCP, when the browser supports it. WebMCP is an early draft API, currently behind a flag in Chrome. The page fills its own form, so a visitor sees the same result the agent gets.
Discovery
Agents find this server through the head links, the HTTP Link header, /.well-known/mcp/server-card.json, /.well-known/mcp.json and /llms.txt.
What we log
Each request writes one log line with the time, the HTTP method, the MCP method, the tool name, the status, the duration, the client name and version, a shortened user agent and, if a call failed, the type of error. We do not log IP addresses, tool inputs or request bodies.
Data rules
The server returns only rows that pass our source gate. A row that has not been checked against its sources is left out, and the answer says how many were left out. The methodology sets out the rule.
