A Claude Code plugin marketplace for local-first context and memory MCP servers:
| Plugin | What it does |
|---|---|
| perseus | Live context engine — pre-resolves git, services, tests, and memory into a ready context briefing at session start (compile-before-context, not runtime tool calls). |
| mimir | Local-first, encrypted (AES-256-GCM) persistent memory — 43 MCP tools over SQLite + FTS5 hybrid search, single Rust binary, fully offline. |
Both are MIT-licensed and run entirely on your machine.
Add the marketplace, then install either plugin:
/plugin marketplace add Perseus-Computing-LLC/claude-plugins
/plugin install perseus@perseus-computing
/plugin install mimir@perseus-computing
The plugins wire up the MCP servers but expect the underlying binaries on your PATH:
- Perseus —
pip install perseus-ctx(PyPI) - Mimir —
curl -sSf https://raw.githubusercontent.com/Perseus-Computing-LLC/mimir/main/scripts/install.sh | sh(installs to~/.local/bin/mimir)
- perseus launches
perseus mcp serve --workspace ${CLAUDE_PROJECT_DIR}, scoping context to your current project. - mimir launches
mimir serve --db ${CLAUDE_PLUGIN_DATA}/mimir.db, keeping the memory database in Claude Code's persistent plugin-data directory so it survives plugin updates.
After installing, confirm the servers are connected with /mcp.
