In-depth architectural comparison of the Toon Memory and Memory Os Cli MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Toon Memory
Knowledge & Memory · Local stdio
Quality: 57/100 (Good) | Auth: No auth required
Memory Os Cli
Knowledge & Memory · Local stdio
Quality: 61/100 (Good) | Auth: other
Verdict Summary: Choose Toon Memory if you need specialized Knowledge & Memory tools running via a local process. Choose Memory Os Cli 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 Toon Memory when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Offline persistent memory for AI coding agents — 37 tools, 80% fewer calls, no LLM
XMemo is user-owned memory for AI agents over a hosted Streamable HTTP MCP endpoint. Save, search, recall, and manage scoped memories across Copilot, Claude, ChatGPT, IDEs, and CLIs. https://xmemo.dev/mcp
Save a decision, pattern, bug, knowledge, or **warning** (negative "do NOT do this" memory, recalled with a boost) — optional TTL, auto-tag inference, `links` to build the memory graph, merge-dedup on same key, auto quality score and confidence. **Write-path intelligence**: each save is annotated w…
memory_recall
Search memory (use BEFORE reading files, filters expired TTL). `mode: "graph"` expands a relationship-aware subgraph for higher precision. `budget: "tiny"
memory_smart_recall
Unified recall**: BM25 + graph + decay + quality in one call. `sessionBias` boosts entries from the current git branch. `explain: true` appends per-entry reasons, `budget_tokens` caps output by estimated tokens. Use at the START of every task. Returns compact, token-efficient output
memory_forget
Lifecycle ops** by key or id: `action: "soft"` (default) marks obsolete, `"hard"` permanently removes, `"restore"` brings back to active, `"supersede"` retires it with a `superseded_by` link to `new_key
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).
Toon Memory is categorized under Knowledge & Memory and uses a local stdio subprocess. In contrast, Memory Os Cli belongs to Knowledge & Memory using local stdio subprocess. Select Toon Memory when you need capabilities focused on knowledge & memory and Memory Os Cli when you require tools for knowledge & memory.

get_mcp_identity
Check XMemo connection status and the connected account/agent.
remember
Save a memory so it can be recalled in future conversations.
recall
Recall the most relevant saved memories before answering.
recall_context
Read a multi-memory context pack. Requires memory:read and does not change content. Use when many memories need explicit budgets; use recall for lightweight answer or get_project_context for project snapshot. max_items/max_tokens bound rendered output.
memory_stats
Show aggregate statistics for XMemo memories.
update_memory
Update the content or metadata of an existing memory.
explain_memory
Explain why a memory exists or matched a query.
restore_memory
Restore a previously deleted memory.
add_expense
Create one XMemo Ledger transaction and backing memory. Requires memory:write; it records a new transaction or reuses a semantic duplicate, and never deletes Ledger records. Use it for a purchase, income, refund, or transfer; use list_ledger_transactions or get_monthly_ledger_summary for reads. amount must be positive; transaction_type defaults to expense; blank transaction_date uses today's UTC date.
