Overview

What is Memory Arbiter MCP?

Memory Arbiter MCP is a Model Context Protocol server that provides a shared local memory store, backed by SQLite, for multiple AI coding tools such as ZCode, Codex, Cursor, and Claude Code. It is designed for developers who need a consistent memory layer across different assistants without relying on cloud services.

How to use Memory Arbiter MCP?

Install the package with pip install memory-arbiter-mcp, then add it as an MCP server to each AI coding tool you use. The shared memory database is stored locally in an SQLite file; no additional infrastructure is required.

Key features of Memory Arbiter MCP

  • Shared memory store across multiple AI coding tools
  • Conflict arbitration with multi-factor resolution
  • User-confirmed memories locked from agent overwrites
  • Zero cloud dependencies, all local SQLite
  • Graceful degradation through fallback search methods

Use cases of Memory Arbiter MCP

  • Maintain a consistent knowledge base across different coding assistants
  • Preserve user-confirmed context that agents cannot accidentally overwrite
  • Resolve conflicting memory entries automatically during multi-agent workflows
  • Keep all memory data locally for privacy and offline usage
  • Fall back to simpler search methods when vector search is unavailable

Frequently asked questions

1

How does conflict arbitration work?

Conflicts are resolved using a dual-timeline priority: user-confirmed entries take precedence, then event time, source trust level, and finally ingest time.

2

Can agents overwrite memories I’ve confirmed?

No. User-confirmed memories are locked and cannot be overwritten by agents, ensuring critical context remains stable.

3

Does this server require cloud services or LLM calls?

No. Everything runs locally on SQLite with no cloud dependencies and zero LLM calls for memory operations.

4

What happens if sqlite-vec is not installed?

The server degrades gracefully through fallbacks: first FTS5, then LIKE queries, and finally reading from a JSONL backup.

5

How is the memory store shared between tools?

Each tool connects to the same MCP server, which reads and writes a single local SQLite database file.
