Overview

What is Memory MCP Server (Go)?

Memory MCP Server (Go) is a Go implementation of the Model Context Protocol server that provides knowledge graph management capabilities. It enables LLMs to create, read, update, and delete entities and relations in a persistent knowledge graph, helping AI assistants maintain memory across conversations.

How to use Memory MCP Server (Go)?

Install via Homebrew, quick install script, pre-built binaries, or build from source. Run the mms command with options for transport (stdio, sse, http), memory file path, port, host, and authentication. Configure MCP clients like Claude Desktop or Cursor by specifying the command and environment variables.

Key features of Memory MCP Server (Go)

SQLite backend with WAL mode for concurrent access
FTS5 full-text search with BM25 ranking and synonym expansion
Graph traversal returning 1-hop related entities
Entity management: merge, update, and conflict detection
Observation metadata tracking source, confidence, and tags
Flexible transport with stdio, SSE, and Streamable HTTP

Use cases of Memory MCP Server (Go)

Persisting AI assistant memory across multiple conversations
Maintaining a knowledge graph of people, concepts, and relationships
Searching and retrieving relevant memories by keyword
Managing and deduplicating entity data

Frequently asked questions

What storage types are supported?

SQLite (recommended) and JSONL (legacy). SQLite offers FTS5, ACID, WAL, and concurrent reads; JSONL is human-readable and starts faster.

How do I migrate from JSONL to SQLite?

Automatic migration occurs by default when using a JSONL memory file path. Manual migration is available with the `--migrate` and `--migrate-to` flags.

What authentication options are available?

Supports Bearer token (`--auth-bearer`) and OAuth 2.1 (`--oauth-user`/`--oauth-pass` and related flags) for SSE and HTTP transports.

What transport protocols are supported?

stdio, SSE, and Streamable HTTP (with optional Bearer or OAuth 2.1 authentication).

Does the server require CGO?

No, it uses pure Go SQLite and works on Linux, macOS, and Windows without CGO.
