Persistent memory for Claude Code, Cursor & Copilot

Stop re-explaining your project every session. One MCP memory server, every AI tool.

decision

Sessions live in Postgres, not Redis

why

One datastore to back up; Redis was only holding 40MB of sessions

Every session starts from zero

Your AI assistant forgets the architecture, the naming rules and the reason you rejected an approach three weeks ago. So you paste the same context again, or you get a confident answer that contradicts a decision your team already made. ContextForge stores those decisions once and serves them to whichever tool you open next.

Without memory"We use Redis for sessions, so store the token there."

With memory"Per your 2026-04-11 decision, sessions go in Postgres. Writing to the sessions table."

One memory, shared across tools

Write a decision in Claude Code and Cursor reads it the same minute. ContextForge runs as a single MCP server, so every client connects to the same store instead of keeping its own copy.

Semantic search over what you wrote

Ask in plain language. Queries match on meaning, so "how do we handle auth failures" finds the note filed as "401 retry policy" without exact keywords or tags.

contextforge - search

ContextForge search returning knowledge, spaces and tasks for one query

Git and task context, kept current

ContextForge reads the branch, recent commits and open tasks alongside your notes, so an assistant answering today knows what shipped yesterday.
