Documented steps
Install/run the mc client and create the alias: mc alias set ALIAS URL ACCESSKEY SECRETKEY. Example: mc alias set myaistor https://myaistor.example.net ACCESSKEY SECRETKEY
ALIAS must be ASCII letters/numbers/hyphen/underscore, at least 1 char, and MUST start with a letter (e.g. myaistor, Test-1). SECRETKEY must be at least 8 characters.
Optional --api S3v4 (default) or S3v2 (deprecated by AWS; use only for legacy S3 services). Optional --path auto/on/off for path-style bucket lookup.
Aliases persist in ~/.mc/config.json (Linux/macOS) or C:\Users\<user>\mc\config.json (Windows). Running alias set again overwrites the existing alias.
On first connect to a self-signed endpoint mc prompts to trust the certificate; accepting stores it in ~/.mc/certs/CAs/ (Linux/macOS).
Known gotchas
Docs moved: official mc reference now lives at https://docs.min.io/aistor/reference/cli/ (the old min.io/docs/minio/linux/... paths are legacy/404).
mc operations are limited by the policies attached to the ACCESSKEY/SECRETKEY you configure; no credentials = it can authenticate but cannot perform unpermitted bucket ops.
S3v2 is deprecated and does not support all API operations; keep S3v4 unless a legacy service requires otherwise.
Secret key shorter than 8 characters is rejected. Docs: https://docs.min.io/aistor/reference/cli/ (mc alias set)
Give your agent this knowledge — and 17,700+ more routes
One MCP install gives any agent live access to the full route map across 6,000+ domains, with trust scores updated by agent consensus:
claude mcp add --transport http waymark https://mcp.waymark.network/mcp
