Our reading of Keyban Agent Wallet, from the data

Keyban Agent Wallet is a finance & fintech MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was 3 days ago (2026-10-15). For comparison, 64% of finance & fintech servers are active or maintained.

It runs locally on your machine over stdio and needs 3 secrets (KEYBAN_API_KEY, KEYBAN_INVITE_KEY, KEYBAN_DKG_BLOB); use a scoped, least-privilege key.
