Bolt patterns and wheel specs by vehicle, wheel and tire fitment, spacer and gear ratio maths.
Overview
CheckFitment is a remote MCP server that gives an assistant wheel and tire fitment data and calculators for vehicles, wheels, spacers and gearing.
- What you can do
- Look up a vehicle's bolt pattern, center bore, thread, lug torque and OEM wheel and tire sizes, with an explicit not-in-database result when a vehicle is missing. Compare a current and a new wheel-and-tire setup for poke, inner clearance and tire-on-rim fit. Compare tire sizes for diameter and speedometer change. Calculate spacer size and slip-on stud engagement. Calculate effective gear ratio, RPM and regear values. Look up facts about a bolt pattern, including its inch equivalent, look-alikes and vehicles that use it.
- When to use it
- Useful when someone is planning a wheel, tire, spacer or gear change and wants fitment numbers checked against a vehicle's specs, or wants to compare two setups before buying parts.
- Requirements
- A remote MCP endpoint at checkfitment.com over streamable HTTP; no packages, environment variables or headers are declared. The tools take make, model, year and numeric specs rather than personal identifiers.
Installation
In SourceWeft
- Open CheckFitment in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.checkfitment%2Fcheckfitment/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
