What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

check_fit
Answer whether a specific red dot optic fits a specific pistol, from source-cited data. Returns fit "direct" (mounts on the slide cut, with the footprint), "adapter" (only through the adapter plate chain in via, with plate maker, model, mount and presented footprints, and plate s
list_optics_for_pistol
List every optic with a cited fit on one pistol, each marked direct (with footprint) or adapter (with the plate chain in via). Use it for questions like "what red dots fit my pistol". Optics not listed have no cited fit, which is not evidence they do not fit. Report the answer ex
list_pistols_for_optic
List every pistol with a cited fit for one optic, each marked direct (with footprint) or adapter (with the plate chain in via). Use it for questions like "what pistols take this red dot". Report the answer exactly as returned: never call an adapter fit a direct fit, and never tur
get_footprint
Describe one optic mounting footprint or plate system (for example RMR, RMSc, ACRO, DPP, Glock MOS): screw and recoil lug counts, the optics that use it, the pistols cut for it directly, and the adapter plates that mount or present it, with sources.
search
Find pistols, optics and footprints by name. Returns slugs, names and page URLs to pass to the other tools. Use it when you are unsure of an exact model name.

Common questions

Is CaliberAPI Pistol Optic Fit safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
