Use it from Claude Code, Cursor or Claude Desktop (MCP)

One standard-library file speaks MCP over stdio and gives your agent governed memory.

curl -fsSL https://cainstudio.online/aether33/mcp-server.py -o ~/.claude/aether33_mcp.py   # read it first
claude mcp add aether33 -e AETHER33_VISITOR=$(python3 -c 'import secrets;print(secrets.token_hex(16))') \
    -- python3 ~/.claude/aether33_mcp.py

Tool	Does
`aether33_remember`	Store text, space, tags, source, expiry. Injections are quarantined by the service.
`aether33_recall`	BM25 search. Never asks for quarantined rows.
`aether33_get`	One memory by id (ids are checked: `mem_` + 16 hex).
`aether33_forget`	Erase text, tags, source and hash; the tombstone keeps the proof.

There is no release tool on purpose: releasing needs the reviewer secret, which a person keeps. Keep AETHER33_VISITOR to see the same memories next time.

Tested 2026-11-02 with a real MCP session (initialize, tools/list, three tool calls, an unknown method) against the live service; it has not yet been run inside a Claude Code session by us.
