Local-first MCP memory layer for coding agents across Claude Code, Codex, Cursor, Cline, Windsurf, and other MCP-compatible hosts.
Sessionmem MCP server exists for a simple reason — assistants are far more useful when they can act on Sessionmem directly instead of describing what you should do. Local-first MCP memory layer for coding agents across Claude Code, Codex, Cursor, Cline, Windsurf, and other MCP-compatible hosts.
WITHOUT sessionmem: You explain the stack. The JWT bug from last week. The Stripe migration that's halfway done. The billing code to stay away from. Same questions. Different day.
Once Sessionmem is connected, these are the calls the assistant has available:
Cursor — CodexCline — WindsurfAntigravity — QCoderBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need one environment variable: ANTHROPIC_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of knowledge and memory servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Sessionmem's toolset — Cursor, Cline, Antigravity — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; 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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.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.
