Our reading of Abe, from the data
Abe is an MCP server from flowinfosystems-index, 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 5 days ago (2026-10-13).
It runs locally on your machine over stdio and needs one secret (FLOW_API_KEY); use a scoped, least-privilege key.
