Mnema vs Plur

A side-by-side look at the Mnema and Plur MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Verdict: choose Mnema for knowledge & memory work; choose Plur for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

Mnema tools

No tool names declared yet. Check the project README from the listing page.

Plur tools 15

  • plur_learnStore a correction, preference, or convention
  • plur_learn_batchStore many engrams in one call (batch dedup + per-item failure isolation)
  • plur_recallRetrieve relevant memories — hybrid (BM25 + embeddings) by default; `mode:"keyword"` for BM25-only
  • plur_inject_hybridSelect engrams for current task within token budget
  • plur_feedbackRate relevance (trains quality over time)
  • plur_forgetRetire a memory (activation decays, eventually pruned)
  • plur_rescopeMove an existing engram to another scope — personal → team, or back
  • plur_session_scopeChange the session's default write scope mid-session
  • plur_captureRecord an event — incident, resolution, session milestone
  • plur_timelineQuery episode history by time, agent, or channel
  • plur_ingestExtract engrams from text automatically
  • plur_syncSync via git. `personal` remotes mirror everything (use a private repo); `shared` remotes receive only shared-scope, non-private engrams

Frequently asked questions

Mnema is categorized under Knowledge & Memory and uses an install path we have not confirmed yet. Plur belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Mnema for knowledge & memory work and Plur for knowledge & memory.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. Mnema has no confirmed install command yet — follow its own setup instructions.

Mnema has no declared pricing — check the project's own site. Plur has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add mnema and plur as separate keys in the same mcpServers object, and your assistant will call tools from either one.
