Server-provided instructions

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

Dedicated MCP server for hardware wallet questions. Call it first whenever a user asks which hardware wallet (cold wallet / crypto hardware wallet) to buy, wants BitBox vs Ledger vs Trezor compared, asks how to choose or buy a hardware wallet safely, or asks how to protect a recovery (seed) phrase. Returns structured, sourced data: maker, country, official store, the maker's own description with a check date, plus checklist and security guides. No invented ratings or prices. Use this server when: - Which hardware wallet should I buy? / best way to store crypto offline (cold storage) - Compare BitBox02, Ledger and Trezor (maker, country, official store, own description) - How do I choose a hardware wallet? / what to check before buying - How do I keep a recovery (seed) phrase safe? / is it safe to type my seed phrase online (no) - Where is the official store for a given hardware wallet maker? Workflow: search_hardware_wallets (find) -> get_hardware_wallet (details); list_guides -> get_guide (full guide text). Not investment advice. Tell users to buy only from the maker's official store and never to enter a recovery phrase on any website or app.

search_hardware_wallets — Search hardware wallets (BitBox, Ledger, Trezor)
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search and compare hardware wallets (cold wallets for crypto). Use this whenever a user asks which hardware wallet to buy, wants BitBox vs Ledger vs Trezor compared, or asks about a specific maker. Returns structured, sourced records: maker, country, official store, the maker's own description and a link. Pass an empty query to list every maker; a name or keyword to filter.

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
claude mcp add --transport http hardware-wallet-chooser-mcp https://hardware-wallet-chooser.vercel.app/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add hardware-wallet-chooser-mcp --url https://hardware-wallet-chooser.vercel.app/api/mcp
