Memento
Memento is a local-first, LLM-agnostic memory layer. It runs an MCP server over a single SQLite file on your machine, so any MCP-capable AI assistant — Claude Desktop, Claude Code, Cursor, GitHub Copilot, Cline, OpenCode, Aider, a custom agent — can read and write durable, structured memory about you, your work, and your decisions.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
backupCreate a point-in-time copy of the database (uses SQLite VACUUM INTO)
completionsEmit a shell completion script (bash, zsh, or fish)
contextPrint runtime context (db, version, registered commands, config snapshot)
dashboardLaunch the local web dashboard (browser UI for browsing and curating memory)
doctorRun diagnostic checks (Node version, database access, optional dependencies)
explainPrint the catalogued meaning of an error code (e.g. STORAGE_ERROR)
exportExport the configured database to a portable `memento-export/v1` JSONL artefact (ADR-0013)
importImport a `memento-export/v1` JSONL artefact into the configured database (ADR-0013, ADR-0019)
initInitialise the database and print MCP client setup snippets
packInstall, preview, uninstall, list, or author memento packs (curated YAML bundles, ADR-0020).
pingSpawn `memento serve`, list tools over MCP stdio, exit
serveRun the MCP server over stdio (blocks until the peer disconnects)
skill-pathPrint the absolute path of the bundled Memento skill (for $(…) shell embedding)
statusPrint a one-screen summary of the install (counts, last event, db size)
store.migrateRun pending database migrations against the configured store
uninstallPrint teardown instructions (config paths and database location)
verify-setupSpawn the MCP server and round-trip a write/read to prove the wiring works
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
17/17 tools missing one or more hints — backup (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); completions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 1 high severity in production deps — @hono/node-server@1.13.7 (high), @hono/node-server@1.13.7 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @psraghuveer doesn't match GitHub owner veerps57
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
