BBrain4Agent

New / early find
New / early find: first tested 2026-11-11. Tested PyPI Brain4Agent 0.0.3 (repo SparkofSpike/Brain4Agent, Apache-2.0 on GitHub but no license field in the PyPI metadata; 98 GitHub stars when tested, created 2026-11-08; not listed on Glama or mcp.so when checked, PulseMCP not checked). CJK-first local memory for agents (SQLite). Launched as documented with `python -m brain4agent.mcp_server`: initialize and tools/list succeeded with no credentials and listed 5 tools. Real calls: b4a_remember stored a turn, b4a_recall found it with a score and missing-term report, b4a_session returned the session, b4a_stats returned counts. b4a_ask was not called (needs a model).
Tool-call test (2026-11-11, direct MCP stdio client, no LLM): pass. 4 of 4 calls passed. b4a_ask (needs an LLM) not called. Evidence: local test run, Nov 11, 2026.

Transport (tested 2026-11-11): stdio

Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
