Frequently asked questions

What is GunSpec?

Read-only firearm specifications: calibers, ammunition, manufacturers and attachment fitment.

How do I install GunSpec?

It runs as a remote server. In Claude Code: claude mcp add --transport http gunspec 'https://mcp.gunspec.io' --header 'X-API-Key: <Your GunSpec API key, from https://gunspec.io/en/profile?section=api-keys>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does GunSpec need an API key?

Yes. It expects X-API-Key, which you set in its configuration.

Who maintains GunSpec?

It is published by io.gunspec. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
