Source-cited pistol red dot compatibility: direct fits, adapter plates and optic footprints.

VerifiedStreamable HTTPWeb executable

Overview

AI-generated overview

Source-cited pistol red dot compatibility: check direct fits, adapter plate chains and mounting footprints for optics and pistols.

What you can do
  • Check whether a specific optic fits a specific pistol, marked direct or adapter with the plate chain
  • List every optic with a cited fit for a pistol, or every pistol with a cited fit for an optic
  • Describe a mounting footprint or plate system, including screw and recoil lug counts and the optics and pistols that use it
  • Search pistols, optics and footprints by name to get slugs and page URLs for the other tools
When to use it
Useful when someone asks whether a red dot fits a given pistol, which optics fit a pistol, which pistols take an optic, or what a footprint such as RMR or Glock MOS involves, and wants answers tied to cited sources.
Requirements
Remote streamable HTTP endpoint at mcp.caliberapi.com; no packages, environment variables or headers declared, and no authentication declared. Network access to the endpoint is needed.
Before you install
Answers are limited to what has a cited fit; an optic or pistol not listed is not evidence of incompatibility, and unknown results should not be read as a definite no. Adapter fits must not be reported as direct fits. Verify results against the cited sources before relying on them for a purchase or installation.

Installation

In SourceWeft

  1. Open CaliberAPI Pistol Optic Fit in the dashboard and add it to a workspace.
  2. 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.caliberapi%2Fpistol-optics/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.

Read the install guide the agent follows

check_fit

Check pistol and optic 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 sources), or "unknown" (no cited fit in the dataset, which is not evidence it does not fit). Returns "needs_clarification" with candidates when a name is ambiguous; call again with a candidate slug. Report the answer exactly as returned: never call an adapter fit a direct fit, and never turn "unknown" into "does not fit". Cite with the returned citation line and link html_url.

Parametersopticrequiredpistolrequired

list_optics_for_pistol

List optics for a 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 exactly as returned: never call an adapter fit a direct fit, and never turn "unknown" into "does not fit". Cite with the returned citation line and link html_url.

Parametersfitpistolrequired

list_pistols_for_optic

List pistols for an 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 turn "unknown" into "does not fit". Cite with the returned citation line and link html_url.

Parametersopticrequired

get_footprint

Get an optic 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.
