Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

Side-by-side MCP evidence comparison
Evidence field	SupermemoryWatchlist candidate	Codebase MemoryMCP100 Selected
Task fit
Best for	Users who want persistent cross-session memory/recall with explicit project scoping.	Repository indexing, symbol search, call-path tracing, impact analysis, and architecture queries across many languages
Not ideal for	Privacy-sensitive workflows that should not persist conversation/project memory outside the client.	Tiny repositories, one-off text searches, or semantic questions unsupported by the indexed parsers
Avoid when	Do not store secrets or sensitive personal/project data unless Supermemory retention/project boundaries meet your requirements.	The source tree cannot be indexed locally or persistent cache files are prohibited

Client coverage

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.	No authentication or API key is documented for local stdio. CBM_ALLOWED_ROOT is an optional filesystem containment control; no containment is imposed when it is unset.
Cost	Supermemory plan/API limits and model/provider costs apply.	The MIT-licensed native software lists no service fee. Local storage and package-manager costs are separate.
Permissions	Can add/read persistent memories available to the authorized account/project.	Indexes repositories, queries code and graphs, performs architecture and impact analysis, manages ADRs and watchers, deletes projects, and writes agent configuration, instruction, Skill, and hook files.
Data handling	Submitted memories are intentionally persisted by the Supermemory service; project scoping and retention are therefore central privacy controls.	The publisher says processing is local and code does not leave the machine. Indexes, embeddings, memories, SQLite data, and logs persist under the local CBM cache directory.
Limitations
Tradeoffs	Promising signal, but it ranks below the current Selected/Watchlist admission cohort on maturity, uniqueness, publisher trust, security clarity, or MCP-native evidence.	Persistent indexing can reduce repeated reads, but consumes local storage and graph results can become stale until the repository is re-indexed. Version 0.10.8 includes correctness and reliability fixes affecting graph/search results and Windows behavior.
Risk context	Intentional persistent storage can retain sensitive context beyond the current session.	Indexing can capture sensitive files, while persistent graph data and installer/configuration writes expand local exposure. Set CBM_ALLOWED_ROOT, protect the cache, and use explicit project paths.
