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.
