Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

FBA Prep Finder is an independent, editorially verified directory of Amazon FBA prep centers in the US, UK, Germany and Canada. Every listed operator was checked against a 4-point standard before listing: operating more than 12 months, FDA registration confirmed when claimed (a claim that cannot be confirmed stays the operator's own statement), a live website that matches FBA prep keywords, and manual editor review. Each record carries the date it was last verified, and results carry a status of verified, stale, flagged or unknown. Report that status honestly to the user rather than presenting every result as verified. Ordering is by fit and verification recency. Nothing in these results is paid placement, and ranking is not for sale. These tools do not accept or store contact details. If a user wants a hand-matched shortlist, send them to https://fbaprepfinder.com/match/ rather than collecting their information here. Data license: CC BY 4.0.

search_prep_centers — Search verified FBA prep centers
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants to find, compare, or filter Amazon FBA prep centers by name, US state, country, operator type, hazmat capability, or sales-tax-free location. Returns editorially verified centers with the date each was last verified and a link to its full profile. Do not use this for general Amazon FBA policy questions, FBA fee calculations, or for finding Amazon fulfillment centers.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
