MCP服务器

Requirements

• Go 1.24+
• github.com/mark3labs/mcp-go v0.19.0+
• modernc.org/sqlite (pure Go SQLite, no CGO)

Installation

Quick Install Script (macOS/Linux)

curl -fsSL https://raw.githubusercontent.com/okooo5km/memory-mcp-server-go/main/scripts/install.sh | bash

Options: -v v0.2.3 for a specific version, -d /usr/local/bin for a custom directory.

Build from Source

git clone https://github.com/okooo5km/memory-mcp-server-go.git
cd memory-mcp-server-go
make build        # binary in .build/

Make sure ~/.local/bin (or your chosen directory) is in your PATH.

Security & Deployment

• Deploy behind TLS (Nginx/Caddy/Traefik), bind server to localhost
• Simple auth: Use --auth-bearer $(openssl rand -hex 32) for programmatic clients
• OAuth 2.1: Use --oauth-user/--oauth-pass for browser-based login (Claude Desktop Connectors). Set --oauth-store in production so registered clients and tokens survive restarts, and run the service with a restrictive umask such as systemd UMask=0077 to protect SQLite WAL/SHM files. Supports PKCE (S256), dynamic client registration, durable token storage, and refresh token rotation with a replay grace window for concurrent or multi-worker clients. Use --oauth-refresh-replay-grace for clients that keep stale refresh tokens in multiple processes
• Forward Authorization header from reverse proxy to backend; set --oauth-issuer to the public URL when behind a proxy
• Run as non-root, open only required ports, enable rate limiting for untrusted clients

Example: macOS Apple Silicon

curl -L https://github.com/okooo5km/memory-mcp-server-go/releases/latest/download/mms_VERSION_darwin_arm64.tar.gz | tar xz chmod +x mms && mv mms ~/.local/bin/ ```

Example System Prompt

You have access to a Knowledge Graph memory system that persists across conversations.

Saving memories:
- create_entities: Add new people, places, concepts (check search_nodes first to avoid duplicates)
- create_relations: Record how entities relate to each other
- add_observations: Add facts to existing entities

Retrieving memories:
- search_nodes: Find relevant entities by keyword (supports synonyms like JS→JavaScript)
- open_nodes: Get full details of specific entities
- read_graph: Get an overview of all stored knowledge (use "summary" mode first)

Managing memories:
- merge_entities: Combine duplicate entities
- detect_conflicts: Find contradictory observations
- update_entities / update_observations: Fix incorrect data

Always check your memory before answering questions that might require past context.

Streamable HTTP Usage

```bash

Usage Examples

Configuration

Or with environment variables and explicit issuer

OAUTH_USER=admin OAUTH_PASS=secret OAUTH_STORE_PATH=/var/lib/mms/oauth.db \ OAUTH_REFRESH_REPLAY_GRACE=24h \ mms --transport http --oauth-issuer https://mcp.example.com ```

Then in Claude Desktop: Settings → Connectors → Add Custom Connector → enter your server URL (e.g., https://mcp.example.com/mcp). Claude will automatically discover the OAuth endpoints and prompt you to log in.
