Shared memory across devices, sessions, and agents for OpenClaw, Claude Code, and Codex.
Shared memory across devices, sessions, and agents for OpenClaw, Claude Code, and Codex. Exposed over MCP by the engrm mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Cross-device persistent memory for OpenClaw, Claude Code, Codex, and any MCP-compatible agent. Start free with 2 devices.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Everything the assistant can do here goes through one of these:
Feature — Engrm FreeCost — £0Cross-device — ✅ 2 devicesSentinel — ✅ (Vibe+)search — Find relevant observations from memory (hybrid FTS5 + vector)timeline — Chronological context around an observationget_observations — Fetch full details by IDsave_observation — Manually save something worth rememberinginstall_pack — Load a curated knowledge pack for your stacksend_message — Leave a cross-device or team noterecent_activity — Inspect what Engrm captured most recentlymemory_stats — View high-level capture and sync healthThis sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Engrm's toolset — Feature, Cost, Cross-device and 10 more — is a fair guide to whether it matches your workflow. It is maintained by dr12hes; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

A knowledge graph your assistant keeps between sessions — entities, relations and observations that persist.
Kill hallucinated APIs — version-accurate, up-to-date library documentation injected straight into context.
Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
A structured scratchpad for hard problems — stepwise reasoning with revisions, branches and visible logic.
Symbol-level code navigation, refactoring and memory for coding agents — the IDE brain your assistant has been missing.
Chat with your second brain — search, read and write vault notes through the Local REST API.
