At a Glance & Executive Verdict
Memory Arbiter MCP
Knowledge & Memory · Remote HTTP/SSE
Quality: 61/100 (Good) | Auth: No auth required
Scrivener MCP
Knowledge & Memory · Local stdio
Quality: 61/100 (Good) | Auth: No auth required
Verdict Summary: Choose Memory Arbiter MCP if you need specialized Knowledge & Memory tools running via a hosted cloud SSE transport. Choose Scrivener MCP if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Memory Arbiter MCP when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You have access to required keys: MEMORY_ARBITER_CLIENT, MEMORY_ARBITER_AGENT_ID, MEMORY_ARBITER_MCP_TRANSPORT.
AI enhancement middleware: precise retrieval replaces full-memory loading (80%+ token cut), rule-based conflict arbitration with explainable reasons, and one local SQLite shared across Claude Code/Codex/Cursor/ZCode. Local-first, zero cloud, MIT. pip install memory-arbiter-mcp
Connect Scrivener 3 writing projects to Claude and other AI assistants. 47 tools for document management, writing analysis, semantic search, character/plot memory, and content enhancement. Progressive skill loading, relationship engine with HMS triplets, and JS fallback for offline semantic search. npm i -g scrivener-mcp
Tools & Capabilities Breakdown
Memory Arbiter MCP Tools (4)
memory
Daily memory operations: remember, find, read, update, submit conflict judgment, and status. Use `action=help` for command-specific fields.
Explicit user-authorized governance: retire a whole memory, resolve a conflict, confirm a memory, correct a judgment, and govern workspace aliases / pending workspaces. Do not use for ordinary updates.
memory_repair
Maintenance and repair: split, rebuild claims/embeddings, cleanup, vector resync, entity backfill, and pending activation. Prefer dry-run first.
Scrivener MCP Tools (6)
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Memory Arbiter MCP is categorized under Knowledge & Memory and uses a remote streaming HTTP/SSE transport. In contrast, Scrivener MCP belongs to Knowledge & Memory using local stdio subprocess. Select Memory Arbiter MCP when you need capabilities focused on knowledge & memory and Scrivener MCP when you require tools for knowledge & memory.
