Zikra — Team Memory for AI Agents

Not just session memory. A shared, governed memory layer for every agent, every person, and every project your team runs.

Most AI memory tools solve one problem: one agent remembers one session better.

Zikra solves a harder problem: multiple people running multiple AI agents across multiple projects — all sharing the same memory pool, with the right person scoped to the right project, the right agent pulling the right context, and millions of memories staying fresh through built-in hygiene scoring.

It's not session memory. It's the shared brain for an AI-native team.

What you get What that means
Multi-agent Claude Code, Gemini CLI, Codex — one pool, one token
Multi-person Owner / admin / dev / viewer roles per project
Multi-project Isolated namespaces; one team runs veltisai, design, global
Scale PostgreSQL backend — handles millions of memories without index rebuilds
Memory hygiene Built-in hygiene prompt: confidence decay, orphan detection, stale cleanup
Structure Not just "save text" — decisions, requirements, prompts, errors, session diaries
Auto-save Stop + PreCompact hooks write every session automatically

Getting Started

Step 1 — Install the server

git clone https://github.com/getzikra/zikra
cd zikra
python3 -m venv .venv
source .venv/bin/activate    # Windows: .venv\Scripts\activate
pip install -e .
python3 installer.py         # interactive setup, ~2 minutes
python3 -m zikra

The installer creates a .env file and generates your admin token. The server binds to http://localhost:8000 by default.

To reach it from other machines, run cloudflared tunnel --url http://localhost:8000 (free, gives you a permanent public URL like https://zikra.yourteam.com).

Step 2 — Enable MCP in Claude Code

Open Claude Code → Settings → MCP → Add Server and paste:

{
  "mcpServers": {
    "zikra": {
      "url": "http://your-server:8000/mcp",
      "headers": { "Authorization": "Bearer YOUR_ZIKRA_TOKEN" }
    }
  }
}

The installer does this automatically when run locally.

Step 3 — Connect your AI coding agent

Paste the prompt for your agent into a session. It handles both first install and updates.

Claude Code:

Fetch https://raw.githubusercontent.com/GetZikra/zikra/main/prompts/zikra-claude-code-setup.md
and follow every instruction in it.

This installs the Stop hook (auto-saves every session), PreCompact hook, and the live statusline bar showing run counts and memory stats.


Updating Zikra

Server:

cd ~/zikra && ./update.sh

Claude Code hooks — re-run the onboarding prompt. It detects your existing install and only refreshes what changed.


Profiles

Profile Storage Hooks Extra deps
Webhook (default) SQLite ¹ none none
Auto-log SQLite ¹ session hooks none
Full SQLite ¹ or Postgres hooks + daemon asyncpg (Postgres only)

¹ SQLite is for local / single-user only. For team deployments set DB_BACKEND=postgres.


Environment variables

Variable Required Default Description
ZIKRA_TOKEN Yes generated Bearer token for the API
OPENAI_API_KEY No Enables semantic search. Keyword-only if absent.
DB_BACKEND No sqlite sqlite or postgres
DB_HOST Postgres only localhost
DB_PORT Postgres only 5432
DB_NAME Postgres only
DB_USER Postgres only
DB_PASSWORD Postgres only
ZIKRA_HOST No 0.0.0.0 Bind address
ZIKRA_PORT No 8000 HTTP port
ZIKRA_DB_PATH No ./zikra.db SQLite database path
ZIKRA_PROJECT No main Default project
OPENAI_API_BASE No https://api.openai.com/v1 Swap for local or compatible embedding endpoint
ZIKRA_EMBEDDING_MODEL No text-embedding-3-small Embedding model name
ZIKRA_DECAY_DAYS No 30 Memory half-life in days
ZIKRA_FREQUENCY_WEIGHT No 0.1 Access-frequency boost weight

How results are ranked

Every search result passes through scoring:

  • Age — recent memories rank higher. Half-life: 30 days. Floor: 0.05.
  • Access frequency — frequently used prompts surface higher (log scale).
  • Confidence — memories saved with lower confidence_score rank lower.

All commands are POST /webhook/zikra with Authorization: Bearer <token>.
