What’s inside

A deterministic, seeded, resettable replica: every operation below executes real state transitions against the twin’s own SQLite state — reads are hash-invariant, writes produce inspectable diffs, and reset restores the seed baseline.

Three surfaces, one state

Mount Slack in a twin environment and the same seeded state serves vendor-shaped REST operations, an MCP endpoint for tool calling, and a generated bf-twin CLI — with copy-on-write sessions per rollout and a one-call reset to the seed baseline. Prefer raw HTTP? The same create works with curl:

API

$ curl -sS -X POST https://blobfish.ai/api/v1/twin/environments \
    -H "X-API-Key: $BLOBFISH_API_KEY" -H "Content-Type: application/json" \
    -d '{"services":["slack"],"ttl_minutes":60}'

Known limitations

Spec-grounded surface with synthetic seeded values; operations outside the spec are not mounted.
