Meridian
Claude Code has no memory between sessions. Meridian fixes that.
Open-source MCP server for persistent AI session memory — shared task log, pinned decisions, human-in-the-loop queue, and tiered handoffs. Works with Claude Code, Cursor, Cline, Claude Desktop, or any MCP client.
Why Meridian
Every AI coding session boots blind. You re-explain the architecture, re-describe the constraints, re-list what's been tried. When context fills up mid-task, everything is lost. This is context debt — and it compounds.
Meridian gives your sessions shared memory. They see the same task log, the same pinned decisions, the same goal state. When context fills up, a new session resumes from a compressed handoff in seconds. No copy-paste, no re-explaining from scratch.
What it is, in 30 seconds
A local MCP server every AI session connects to. They share goal state, see each other's task log, and resume from a compressed handoff when context fills up.
Two ways to run Meridian:
- Self-host — free forever, any team size. Clone and run in 2 commands.
- Hosted at usemeridian.us — 30 days free (no card), then $20/mo Standard.
