Portable long-term memory store for agents, exposed over MCP

PyPI CI License: COCL 1.0 Suite

AI Agents & LLMOps — build, route, evaluate, and secure agents.

pip install cognis-memorybank
memorybank scan .            # → prioritized findings in seconds

🔎 Example output

Real, reproducible output from the tool — runs offline:

$ memorybank-emit --version
memorybank 0.1.0
$ memorybank-emit --help
usage: memorybank [-h] [--version] [--format {table,json}] [--path PATH]
                  {remember,recall,forget,list,stats} ...

Portable agent memory store.

positional arguments:
  {remember,recall,forget,list,stats}
    remember            store a new memory
    recall              retrieve memories ranked by a query
    forget              delete a memory by id
    list                list every memory
    stats               show bank statistics

options:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --format {table,json}
  --path PATH           path to the JSONL memory bank
$ memorybank-emit stats
{
  "count": 0,
  "halflife_days": 14.0,
  "path": "C:\\Users\\user\\cognis-demo\\memorybank\\memorybank.jsonl",
  "tags": {},
  "total_accesses": 0
}

Blocks above are real memorybank output — reproduce them from a clone.

Usage — step by step

  1. Install (Python 3.8+, stdlib only):
    pip install memorybank
    
    The store is a single JSONL file (default memorybank.jsonl, override with --path or MEMORYBANK_PATH).
  2. Remember a fact, optionally tagged and weighted:
    memorybank remember "User prefers metric units" --tag prefs --importance 2.0
    
  3. Recall the most relevant memories for a query (ranked, recency-aware):
    memorybank recall "what units?" --limit 5 --tag prefs
    
    Add --no-touch to retrieve without updating recency.
  4. Read the output — every command emits JSON by default; switch to a human table:
    memorybank --format table list
    memorybank stats                 # bank-wide counts/metrics
    memorybank forget <id>           # delete one memory by id
    
  5. Drive it from an agent loop / CI — point each session at its own bank file:
    export MEMORYBANK_PATH=./agent_state/memory.jsonl
    memorybank recall "$TASK" --limit 8 | jq -r '.[].text'
    
    Exits non-zero on error so callers can detect failures.

Why memorybank?

agent-memory niche

memorybank is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.

Features

  • ✅ Fast, single-purpose CLI
  • ✅ JSON / SARIF output for pipelines
  • ✅ CI fail-gate (--fail-on)
  • ✅ MCP server for AI agents
  • ✅ Runs on Linux/macOS/Windows · Docker · devcontainer
  • ✅ Ports in Python, JavaScript, Go, and Rust (ports/)

Quick start

pip install cognis-memorybank
memorybank --version
memorybank scan .                       # scan current project
memorybank scan . --format json         # machine-readable
memorybank scan . --fail-on high        # CI gate (non-zero exit)

Example

$ memorybank scan .
  [HIGH    ] MEM-001  example finding             (./src/app.py)
  [MEDIUM  ] MEM-002  another signal              (./config.yaml)

Use it from any AI stack

memorybank is interoperable with every popular way of using AI:

  • MCP servermemorybank mcp (Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet)
  • OpenAI-compatible / JSON — pipe memorybank scan . --format json into any agent or LLM
  • LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
  • CI / scripts — exit codes + SARIF for non-AI pipelines

How it compares

Cognis memorybank agent memory
Self-hostable, no account varies
Single command, zero config ⚠️
JSON + SARIF for CI varies
MCP-native (AI agents)
Polyglot ports (JS/Go/Rust)
Open license ✅ COCL varies

Built in the spirit of agent memory, re-framed the Cognis way. Missing a credit? Open a PR.

Integrations

Pipes into your stack: SARIF for code-scanning, JSON for anything, an MCP server (memorybank mcp) for AI agents, and a webhook forwarder for SIEM/Slack/Jira. See docs/INTEGRATIONS.md.
