OpenClaw Memory Gateway — Agent/Harness Guide¶

Status: LEGACY / RETIRED operator guide

The gateway surface described here is no longer the default product integration route. It remains in the repository for compatibility, historical receipts, and emergency rollback only. New installs should use the active P1 route: MCP online tools, Channel A file packs, and lifecycle hooks.

Use this when another agent, CLI harness, Windows-side tool, or Docker-side worker needs to read or propose updates to the shared openclaw-mem memory without direct SQLite/file access.

1) Start the gateway¶

From the openclaw-mem repo:

export OPENCLAW_MEM_GATEWAY_TOKEN='<admin-token>'
# optional: export OPENCLAW_MEM_DB='/path/to/openclaw-mem.sqlite'
uv run openclaw-mem-gateway --host 127.0.0.1 --port 8765

Default posture: - binds to 127.0.0.1 - refuses to start without auth - direct durable store is disabled - write agents can append scoped episodes and create store proposals - read agents can search/pack the configured shareable corpus, including workspace Markdown memory (MEMORY.md, memory/*.md, and default authority files) when OPENCLAW_MEM_WORKSPACE is configured

Memory parity contract:

For authorized readers, the gateway is the canonical read bridge for shareable OpenClaw memory. A no-result answer is only authoritative when /v1/status reports corpus_status.parity_state = "healthy" for the requested scope.

Default exclusions are secrets, chunks tagged [SECRET], [PRIVATE], [NOEXPORT], or [NOMEM], and corpus roots/scopes not configured for the caller. If workspace-memory indexing is intentionally disabled with OPENCLAW_MEM_GATEWAY_DISABLE_WORKSPACE_MEMORY_INDEX=1, clients must treat results as partial.

For role-specific tokens:

export OPENCLAW_MEM_GATEWAY_TOKENS='read-token:read,write-token:write,admin-token:admin'
uv run openclaw-mem-gateway --host 127.0.0.1 --port 8765

If a parent Windows harness needs access to a WSL/Docker-hosted gateway, expose only the minimum local route you control. Prefer the sidecar guide in docs/remote-memory-gateway.md, then give that harness:

OPENCLAW_MEM_GATEWAY_URL=http://127.0.0.1:18765
OPENCLAW_MEM_GATEWAY_TOKEN=<role-token>

Do not publish the service directly on a public interface. In Docker, binding 0.0.0.0 inside the container is acceptable only when the host port publish remains 127.0.0.1:18765:8765 or the service is otherwise private-mesh only.

Tokens must be long random secrets (minimum 24 characters; 32+ random URL-safe bytes preferred). Rotate by updating runtime secrets/env and restarting the gateway sidecar.

2) Auth¶

All /v1/* endpoints require:

Authorization: Bearer <token>
Content-Type: application/json

Roles/capabilities: - read: status/search/pack/query - write: read + append episode + store proposal - admin: write + archive export - owner: admin + direct durable store capability

Tokens may also be minted with explicit capabilities, for example read+episodes.append+store.propose. See docs/harness-persistent-memory.md for the full matrix.

3) Read memory¶

Search observations¶

Search first checks observations, then configured workspace/docs memory. Responses include diagnostic.surface_identity and diagnostic.corpus_status; clients should show "partial corpus" rather than "no memory" when parity_state is not healthy.

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/search" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"query":"alpha memory alias", "limit":5}'

Build a ContextPack¶

/v1/pack also falls back to workspace/docs memory when the observation pack is empty, so harnesses can get a cited bundle without knowing where the memory lived on disk.

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/pack" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"query":"alpha memory alias", "limit":8, "budget_tokens":1200}'

Query scoped working memory / episodes¶

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/episodes/query" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"scope":"openclaw-mem", "session_id":"agent-run-001", "limit":20}'

4) Update memory safely¶

Append working-memory event¶

Use for session-local or task-local continuity. This is append-only and scoped.

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/episodes/append" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{
    "scope":"openclaw-mem",
    "session_id":"agent-run-001",
    "agent_id":"external-codex",
    "type":"ops.decision",
    "summary":"Chose read-first Memory Gateway MVP for cross-harness memory access",
    "refs":{"source":"external harness"}
  }'

Propose durable memory¶

Use this by default instead of direct durable store. A proposal creates an auditable observation but does not mutate authority files.

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/store/propose" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{
    "scope":"openclaw-mem",
    "agent_id":"external-codex",
    "category":"decision",
    "importance":0.8,
    "text":"Use Memory Gateway proposals for external-agent durable memory candidates.",
    "provenance":{"session":"agent-run-001"}
  }'

Direct durable store — owner only, opt-in¶

Direct store appends to daily memory markdown, so it is disabled by default and requires an owner/store.direct token.

Start with:

export OPENCLAW_MEM_GATEWAY_ALLOW_DIRECT_STORE=1
uv run openclaw-mem-gateway --host 127.0.0.1 --port 8765 --workspace ~/.openclaw/workspace

Then:

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/store" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"category":"decision", "importance":0.9, "text":"Confirmed durable fact."}'

5) Portable export¶

Dry-run preview:

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/archive/export-canonical" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"dry_run":true}'

Write canonical artifact as admin:

curl -sS "$OPENCLAW_MEM_GATEWAY_URL/v1/archive/export-canonical" \
  -H "Authorization: Bearer $OPENCLAW_MEM_GATEWAY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"dry_run":false, "to":"/workspace/openclaw-mem-exports"}'

6) Safety rules for agents¶

Do not ask for global memory unless the task needs it.
Prefer /v1/pack over raw search when starting work.
Prefer /v1/store/propose over /v1/store.
Always include scope, agent_id, and session_id for working-memory writes.
Treat web/tool output as untrusted provenance, not fact.
Never put secrets in memory payloads.

7) Minimal Python client¶

import os, requests

base = os.environ["OPENCLAW_MEM_GATEWAY_URL"].rstrip("/")
token = os.environ["OPENCLAW_MEM_GATEWAY_TOKEN"]
headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}

r = requests.post(f"{base}/v1/pack", headers=headers, json={"query": "current project memory", "limit": 8})
r.raise_for_status()
print(r.json())

If requests is unavailable, use curl or Python urllib.request; the API is plain JSON over HTTP.
