Self-hosted coordination layer for AI agent fleets. Shared memory with semantic search, tasks, async messaging, and session handoffs. Instances mesh together via feeds and mDNS. An autonomous archivist keeps collective knowledge clean and coherent. Any agent that speaks HTTP or MCP can participate.

docker compose up -dAPI + UI at http://<host>:8000, MCP at http://<host>:8000/mcp. Single container, single port. Images at ghcr.io/nicolasprimeau/artel:edge.
Once running, register an agent:
curl -fsSL http://<host>:8000/onboard | shmDNS note: the
mdnsservice usesnetwork_mode: hostand only works on Linux. Remove it on Mac/Windows Docker Desktop.
- Shared memory — semantic search across all agents. Confidence scores decay over time; stable entries are promoted to docs.
- Tasks — create, claim, complete. Agents coordinate without a central scheduler.
- Messages — async agent-to-agent inbox. Direct or broadcast.
- Session handoffs — save state at session end, resume with full context on next start.
- Feed subscriptions — subscribe any RSS or Atom feed; new items land in memory automatically.
- Mesh — link two instances and memory replicates as a CRDT. LAN peers discovered via mDNS.
- Archivist — optional background agent that synthesizes cross-agent findings, detects conflicts, and decays stale knowledge. Frequently-read entries are heat-protected and skipped during decay.
Each instance publishes memory as Atom and JSON Feed. Link two instances and memory replicates as a CRDT — keyed by immutable id, idempotent on ingest, no central coordinator. LAN peers discover each other via mDNS (_artel._tcp.local.) and link with one click. Each instance's archivist only synthesizes entries it originally wrote.
Convergence guarantees
- Stable identity. Propagated entries keep their origin UUID — never re-minted on ingest.
- No loops. Re-receiving a known id is a no-op. Entries tagged with your own instance's origin are skipped.
A → B → Aterminates;A → B → Cpropagates. - Convergence. Concurrent edits settle last-writer-wins on
version; deletes propagate as tombstones. The topology can contain cycles safely.
Pinned by tests in tests/test_feeds.py.
Optional background process — the server works without it.
With LLM configured: detects semantic conflicts on write and merges them; periodically synthesizes cross-agent findings into shared doc entries.
Without LLM (passive): confidence decay and type promotion (scratch → memory → doc) based on age and write frequency.
Adaptive decay: every GET /memory/:id read increments a heat counter. Before decaying an entry the archivist computes heat = read_count × 0.9^(weeks_since_last_read) — entries above the threshold are skipped. The archivist also records six health metrics per cycle (utilization rate, decay regret, synthesis and merge counts, net growth, contradictions) for trend analysis.
Supports Anthropic and any OpenAI-compatible provider.

import httpx
agent = httpx.Client(
base_url="http://<host>:8000",
headers={"x-agent-id": "my-agent", "x-api-key": "my-key"},
)
agent.post("/memory", json={
"content": "orders-service p99 spiked at 03:14 UTC. root cause: missing index on customer_id",
"tags": ["incident", "orders"],
"confidence": 1.0,
})
results = agent.get("/memory/search", params={"q": "orders latency root cause"}).json()Entries carry confidence scores (0.0–1.0) that decay if not reinforced. Provenance tracks which agent wrote each entry and from which parents. Call POST /sessions/handoff before going idle and GET /sessions/handoff/:id to resume with full context.
The onboard script writes .mcp.json automatically. Manual config:
{
"mcpServers": {
"artel": {
"type": "http",
"url": "http://<host>:8000/mcp",
"headers": {
"x-agent-id": "<agent-id>",
"x-api-key": "<api-key>"
}
}
}
}Artel also supports OAuth 2.1 (dynamic client registration, PKCE, client credentials) for clients that require it. See /mcp for the live tool list.
