Crbro Memory MCP Server

CRBRO is a local MCP (Model Context Protocol) server that gives your AI assistant persistent long-term memory across sessions. It uses a biological neural architecture - cortex, synapses, hippocampus - to store, connect, and retrieve knowledge automatically. Its README documents 15 tools, including crbro_boot, crbro_inspect, crbro_learn.

People who work with knowledge graph and memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Crbro Memory

Claude Code

claude mcp add octonove-crbro-memory -- npx -y crbro-memory

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "octonove-crbro-memory": {
      "command": "npx",
      "args": [
        "-y",
        "crbro-memory"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package crbro-memory - unscoped; check the name against the project README before installing

registry namespace io.github.Octonove is GitHub-verified and matches the repo owner

03 · What Crbro Memory can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can remove for good, keeping a copy in .quarantine/ first - entries of a neuron, a whole neuron (two-step with confirm_token), a session log, create, strengthen, set the strength of or delete (action=disconnect) a connection between neurons, read (no arguments) or update the active working context - topics, open items, discard or clear, and find credentials stored in the brain, session logs included - reports the kind, never the value.

The 15 tools it gives your agent

Extracted from the project's README - what crbro-memory lets an agent do.

crbro_boot
- Boot the brain at session start - loads hot topics, context, the last three sessions and the retired_tools map
crbro_inspect
- Read-only views by id or name: view=status, neuron, neurons, sessions, global_map. view=neuron is an index by default - every entry as id, kind, date and previe
crbro_learn
- Store a fact, decision, pattern, preference, error or debt - with the keywords a future question may use. supersedes retires the old version in the same call
crbro_recall
- Search every stored line, not just topic names - returns what matched, how confidently, and the topic's next best lines. Several phrasings at once are fused by
crbro_revise
- Retire facts (and decisions, patterns, errors, debts via entries) as superseded or retracted, reactivate them with status=active, and edit summary, domain, tags
crbro_forget
- Remove for good, keeping a copy in .quarantine/ first - entries of a neuron, a whole neuron (two-step with confirm_token), a session log; restore and merge_into
crbro_connect
- Create, strengthen, set the strength of or delete (action=disconnect) a connection between neurons
crbro_context
- Read (no arguments) or update the active working context - topics, open items, discard or clear
crbro_map
- Keep one living map of how a topic's system works - replaced whole, never patched
crbro_consolidate
- End-of-session consolidation - the only way to log a session; links the topics it wrote and syncs spaces
crbro_maintenance
- Brain maintenance - heat, pruning, integrity, repair, unarchive, index rebuild
crbro_audit
- Find credentials stored in the brain, session logs included - reports the kind, never the value
show all 15 tools
crbro_secret
- Put a credential in the OS keychain and keep only its name in the brain
crbro_space
- Create, join, sync or leave a team space - a private git repo for shared projects
crbro_share
- Put one project into a space, after showing exactly what would be sent; unshare stops following it
