CPersona
MCP Memory Server
Persistent memory for AI agents, over MCP. One SQLite file you own. No LLM in the loop. Honest when recall degrades.

Standalone repository — This is the standalone version for use with Claude Desktop, Claude Code, Codex CLI, Cursor, VS Code, and any other MCP client (registration table).
If you are a ClotoCore user, install CPersona from the in-app marketplace (ClotoHub) instead — it distributes this same repository.
Project status — 2.4.x is Stable; 2.5.x is Current, an internal
stabilization line where all fixes land, pending production-soak
certification. The DB schema is preserved across the line. Additive,
rollback-safe features may land here as well ([lifecycle standard
§2.6](https://cloto-dev.github.io/CPersona/RELEASELIFECYCLESTANDARD/#26-feature-releases-within-a-line));
a change that cannot be rolled back waits for 2.6. Which version to run, and
how long each line keeps receiving fixes:
SUPPORT.md.
Where the lines are heading: the roadmap.
Upgrading from 2.5.2 or earlier? Two things need a decision from you.
v2.5.3 will not start the HTTP transport without CPERSONAAUTHTOKEN,
wherever it binds — set one, or opt out with
CPERSONAALLOWUNAUTHENTICATED_HTTP=true (why; stdio is unaffected).
v2.5.2 changed tool response shapes — branch on ok is false, and treat any
response carrying error as a failure whether or not ok is present
(contract §10).
The Problem
Claude forgets everything between sessions. Every conversation starts from zero — no context about your project, your preferences, or what you discussed yesterday.
cpersona fixes this. It's an MCP server that stores memories in a local SQLite file and retrieves them through hybrid search. Claude remembers you. It runs against any MCP-compatible host — Claude Desktop, Claude Code, ClotoCore (the AI agent platform where cpersona originated, and whose memory layer it is), or a client of your own.
Quick Start
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
