@teambrain/mcp

TeamBrain's MCP server and local daemon.

Serves the team's memories to any MCP-capable agent (Claude Code, Cursor, …) and persists redacted session events — the vendor-neutral surface everything agent-facing goes through.

• Four MCP tools (stdio, official SDK): memory_context() (session-start bundle, required-first, ≤2,000 tokens), memory_search(query, k), memory_propose(draft) (local spool only — never writes to the brain), memory_feedback(id, useful).
• Injection mitigation: memory bodies are rendered inside fenced blocks marked data, not instructions, with fences sized so body content can never break out.
• Daemon (tb serve): watches the brain repo, keeps the index fresh (checksum poll + fs-events nudge), accepts capture events on a local socket (unix socket / Windows named pipe), writes a heartbeat for tb doctor.
• Session spool: redacted event records are committed to a dedicated, never-merged teambrain/sessions branch via pure git plumbing. The user-scope store (~/.teambrain/user/) is physically unreachable from the sync code — enforced by test at the git-object level.

npm install @teambrain/mcp

Part of TeamBrain — most users want @teambrain/cli, which registers this server via tb install.
