Side-by-side MCP evidence comparison
Evidence field	SupermemoryShortlist candidate	MCPVault for ObsidianMCP100 Recommended
Task fit
Best for	Users who want persistent cross-session memory/recall with explicit project scoping.	Obsidian users who want local search and supervised note maintenance Vaults protected by version control or reliable backups Users able to expose only a dedicated, bounded vault
Not ideal for	Privacy-sensitive workflows that should not persist conversation/project memory outside the client.	Unbacked-up personal knowledge bases Read-only research where a simpler filesystem search is sufficient Enterprise knowledge requiring centralized authorization and audit controls
Avoid when	Do not store secrets or sensitive personal/project data unless Supermemory retention/project boundaries meet your requirements.	The vault contains secrets, regulated data, or material that cannot reach the selected AI provider Write, move, and delete tools cannot be confirmed by a human The vault path cannot be narrowed to a dedicated directory

Client coverage
Client coverage details	Not documented	Claude Code✓ Local stdio Claude Desktop✓ Local stdio Codex✓ Local stdio VS Code✓ Local stdio Cursor✓ Local stdio OpenCode✓ Local stdio
Client coverage note	Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
Authentication	OAuth is the default; API key/Bearer authentication is an alternative.	None at the local stdio layer.
Cost	Supermemory plan/API limits and model/provider costs apply.	MCPVault is MIT licensed and free to run locally. MCP-host, model, backup, and storage costs remain.
Permissions	Can add/read persistent memories available to the authorized account/project.	The server has filesystem read and write access within the supplied vault root, including note creation, overwrite or patch, frontmatter changes, moves, tags, and deletion. Operating-system permissions and the configured vault path are the primary boundary.
Data handling	Submitted memories are intentionally persisted by the Supermemory service; project scoping and retention are therefore central privacy controls.	Vault content and metadata are read locally and returned to the MCP client and model. Changes are written directly to local files. MCPVault states that it does not receive, store, or transmit vault data, while the selected AI provider still processes content sent by the client.
Limitations
Tradeoffs	Promising signal, but it ranks below the current Recommended/Shortlist admission cohort on maturity, uniqueness, publisher trust, security clarity, or MCP-native evidence.	Local stdio avoids a hosted MCP service, but note contents still enter the MCP host and model context. Frontmatter-aware writes are more useful than generic file access but increase integrity risk. npx makes setup simple, while stricter environments may prefer a pinned and reviewed package version. Version 0.16.0 migrated to MCP TypeScript SDK v2 / protocol 2026-07-28 while retaining dual-era stdio compatibility.
Risk context	Intentional persistent storage can retain sensitive context beyond the current session.	A selected vault can contain a large body of private knowledge, and write tools can overwrite, move, or delete it. Use a dedicated vault, reliable backups or version control, an absolute path, a reviewed package version, and explicit approval for writes.
