Plur MCP Server
Persistent, open memory for AI agents - local-first, zero-cost, shared across MCP tools (Claude Code, Hermes, OpenClaw, Cursor). Your agent's memory is plain-text engrams you can read, correct, and delete - not weights you can't. Its 15 documented tools cover plur, learn.
People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Plur
before you install - you'll need
The README does not document required environment variables for a basic install.
Claude Code
claude mcp add plur-ai-plur -- npx -y @plur-ai/mcp Claude Desktop / Cursor / VS Code - add to config
{
"mcpServers": {
"plur-ai-plur": {
"command": "npx",
"args": [
"-y",
"@plur-ai/mcp"
]
}
}
} Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
Using another client? Same JSON, different key

02 · Evidence
Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.
runs as local process (stdio) - runs on your machine with your user's permissions
license Apache-2.0 - declared in the repository
npm package @plur-ai/mcp - published under the repo owner's npm scope (@plur-ai)
registry namespace io.github.plur-ai is GitHub-verified and matches the repo owner
03 · What Plur can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
What you can build
With this server connected, an agent can retrieve relevant memories - hybrid (BM25 + embeddings) by default, select engrams for current task within token budget, move an existing engram to another scope - personal → team, or back, and query episode history by time, agent, or channel.
The 15 tools it gives your agent
Extracted from the project's README - what plur lets an agent do.
- plur_learn
- - Store a correction, preference, or convention
- plur_learn_batch
- - Store many engrams in one call (batch dedup + per-item failure isolation)
- plur_recall
- - Retrieve relevant memories - hybrid (BM25 + embeddings) by default; mode:"keyword" for BM25-only
- plur_inject_hybrid
- - Select engrams for current task within token budget
- plur_feedback
- - Rate relevance (trains quality over time)
- plur_forget
- - Retire a memory (activation decays, eventually pruned)
- plur_rescope
- - Move an existing engram to another scope - personal → team, or back
- plur_session_scope
- - Change the session's default write scope mid-session
- plur_capture
- - Record an event - incident, resolution, session milestone
- plur_timeline
- - Query episode history by time, agent, or channel
- plur_ingest
- - Extract engrams from text automatically
- plur_sync
- - Sync via git. personal remotes mirror everything (use a private repo); shared remotes receive only shared-scope, non-private engrams
show all 15 tools
- plur_status
- - Check system health and engram counts
- plur_receipt
- - Counted, local report of what your memory retrieved for you
- plur_outbox
- - Inspect (and retry) team writes queued while their store was unreachable

Yes - as of 2026-08-25, its last commit was 2026-08-23 and it shipped 10+ releases in the last 90 days. We re-verify nightly.
What can Plur do?

How do I install Plur?
Run `npx -y @plur-ai/mcp`. The README does not document required environment variables for a basic install. You can also paste the ready-made client config above.
Does Plur run locally?
Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
