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
}

Usage — step by step
- Install (Python 3.8+, stdlib only):
The store is a single JSONL file (defaultpip install memorybankmemorybank.jsonl, override with--pathorMEMORYBANK_PATH). - Remember a fact, optionally tagged and weighted:
memorybank remember "User prefers metric units" --tag prefs --importance 2.0 - Recall the most relevant memories for a query (ranked, recency-aware):
Addmemorybank recall "what units?" --limit 5 --tag prefs--no-touchto retrieve without updating recency. - 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 - Drive it from an agent loop / CI — point each session at its own bank file:
Exits non-zero on error so callers can detect failures.export MEMORYBANK_PATH=./agent_state/memory.jsonl memorybank recall "$TASK" --limit 8 | jq -r '.[].text'

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 server —
memorybank mcp(Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet) - OpenAI-compatible / JSON — pipe
memorybank scan . --format jsoninto 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.
