Persistent memory
for AI agents.

Semantic search, strength decay, auto-consolidation.
One line to connect any MCP-compatible agent.

shell

claude mcp add kioku \
    https://mcp.takizen.xyz/mcp \
    --transport http \
    --header "Authorization: Bearer YOUR_API_KEY"

How it works

Add kioku to your MCP config once. Works with Claude Code, Cursor, any MCP-compatible client.

Agent calls remember() automatically. Semantic dedup prevents noise. Strength starts at 1.0.

Semantic search returns the most relevant memories. Each recall reinforces strength.

Tools

remember(content, tags?)

Store a memory. Semantic dedup: if similarity > 0.92, updates existing instead of creating duplicate.

recall(query, k?)

Semantic search. Returns k most relevant memories. Reinforces strength of results.

forget(id)

Archive a memory to cold storage. Not permanent — recoverable for 90 days.

list(tags?, min_strength?)

List memories filtered by tags or minimum strength. Default: all active memories.
