io.github.Goldentrii/agent-recall

Correction-first agent memory that learns how you think, with precision KPI tracking and 5 cognitive layers—local-only by default.

What is the io.github.Goldentrii/agent-recall MCP server?

AgentRecall is an MCP server that provides persistent, compounding agent memory organized into 5 cognitive layers (episodic, semantic, procedural, narrative, correction). It automatically captures corrections and tracks a precision KPI to measure whether agents actually heed warnings, storing everything locally in markdown under ~/.agent-recall/ with optional semantic search via OpenAI embeddings.

AgentRecall turns corrections into learning. Every time you correct your agent, that correction is stored, weighted, and recalled in future sessions. After multiple sessions, your agent doesn't just remember your project—it understands how you think. The system uses FSRS-lite spaced repetition decay and keyword+RRF retrieval (fully local by default), with optional vector search. It's designed around the principle that memory only compounds if used automatically, not on demand.

io.github.Goldentrii/agent-recall MCP server FAQ

What is AgentRecall?

AgentRecall is an MCP server that creates a learning loop for AI agents. It captures corrections, stores them in 5 cognitive memory layers, and automatically recalls relevant warnings in future sessions. The core innovation is a precision KPI that tracks whether the agent actually heeds warnings—if precision drops below 0.3, that warning stops being injected as noise.

Is AgentRecall free?

Yes, AgentRecall is MIT-licensed and open source. It runs entirely locally on your machine by default. Optional semantic vector search requires an OpenAI API key, but the default keyword+RRF retrieval is fully local with zero cloud dependency.

How do I install it in Claude Code or Cursor?

For Claude Code: `claude mcp add --scope user agent-recall -- npx -y agent-recall-mcp`. For Cursor, add to `.cursor/mcp.json`: `{ "mcpServers": { "agent-recall": { "command": "npx", "args": ["-y", "agent-recall-mcp"] } } }`. For other editors, use the generic MCP JSON format.

Do I need authentication or API keys?

No authentication is required to use AgentRecall locally. All memory is stored in `~/.agent-recall/` as markdown files. Optional semantic vector search requires `OPENAI_API_KEY`, but leaving it unset keeps everything local with zero cloud calls.

What are the 5 memory layers?

Episodic (session journal), Semantic (topic-clustered facts with wikilinks), Procedural (IF-THEN rules), Narrative (project phases and synthesis), and Correction (behavioral rules with precision KPIs). All are stored as local markdown under `~/.agent-recall/projects/`.

How does the precision KPI work?

Each correction tracks `precision = heeded / retrieved`—of the times AgentRecall surfaced a warning, how often did the agent act on it? Corrections with precision < 0.3 are archived as noise; those ≥ 0.8 are promoted faster as high-signal insights.

1. Install the MCP server (Claude Code):

claude mcp add --scope user agent-recall -- npx -y agent-recall-mcp

Generic MCP JSON for other clients:

{ "mcpServers": { "agent-recall": { "command": "npx", "args": ["-y", "agent-recall-mcp"] } } }

2. First message of every new session, run the loop:

At the start of a session, call session_start to load context.
When the human corrects you, call remember with type "correction".
At the end of a session, call session_end to compound what you learned.
</details>

What & Why

AgentRecall is not a memory tool. It's a learning loop. Memory is the mechanism; understanding is the goal. Every time you correct your agent — "no, not that version", "put this section first", "ask me before you assume" — that correction is stored, weighted, and recalled next time. After 10 sessions your agent doesn't just remember your project; it understands how you think.

  • Correction-first. When you say "no, that's wrong", we log a CorrectionRecord with severity, holder, and evidence. After N confirmations across sessions it auto-promotes to a cross-project insight.
  • Measurable learning loop. Every correction tracks retrieved_count, heeded_count, recurrence_count, precision. The KPI that matters: did the same bug recur after we warned about it?
  • Five memory types. Episodic, semantic, procedural, narrative, correction — mapped to the canonical cognitive-psychology taxonomy (Squire 2004, Tulving 1972).
  • Local markdown, local by default. Everything lives in ~/.agent-recall/. Open it in Obsidian, grep it in the terminal, version it in git. The default keyword + RRF retrieval is fully local — zero cloud, no API keys, no lock-in. Semantic vector search is optional: set OPENAI_API_KEY and query/content text is sent to OpenAI for embeddings. Leave it unset and nothing leaves your machine.
  • Backed by published math. FSRS-lite decay (Ebbinghaus → SuperMemo → FSRS-6), RRF fusion (Cormack 2009). A Modern Hopfield re-rank primitive (Ramsauer 2020) ships in the codebase but is not wired into the default retrieval path — what runs today is BM25/keyword + RRF, plus optional vector search.

The Automaticity Law. Memory only compounds if it's used automatically, not on demand. Measured on the live corpus: push channels (session_start, session_end, correction hooks) show repeated behavior-changing usage, while pull channels had zero organic calls across 44 projects over weeks of real use — including from the agent that built them. That's why only 5 tools ship by default; the two-verb model (inhale/exhale) carries all the compounding value, and everything else is opt-in via --full.

Injection Precision KPI. Every correction tracks precision = heeded / retrieved — of the times we surfaced this warning, how often did the agent actually act on it? precision < 0.3 → archive candidate (noise we should stop injecting). precision ≥ 0.8 → promote faster (high-signal, compound it sooner). This is the measurability claim: a memory system you can prove is working.

5 Memory Layers

The canonical cognitive-psychology taxonomy mapped to your agent's filesystem:

LayerTypeWhat it holdsPath
1EpisodicWhat happened in each session, chronologically. Auto-written during work.journal/
2SemanticTopic-clustered facts with [[wikilinks]]: Architecture, Goals, Blockers.palace/rooms/
3ProceduralIF-THEN production rules — reusable how-tos.palace/skills/
4NarrativeProject phases: Goal → What was hard → How solved → Synthesis.palace/pipeline/
5CorrectionBehavioral calibration: rules the agent must follow, with precision KPIs.corrections/
+AwarenessCross-project insights promoted from N-confirmed corrections — the compounding layer.palace/awareness

All layers share one canonical naming grammar (<scope>/<type>/[<topic>/]<temporal>--<slug>.md) so any agent can compose retrieval paths from intent. Existing files keep working via a legacy_path view — no migration needed.


The Session Loop

CommandWhenWhat it does
🔴 /arstatusFirst — every sessionStatus board across ALL projects: pending work, blockers, relevance scores. Pick by number.
/arstartAfter picking a projectLoad deep context: palace rooms, corrections, task-specific recall.
🔴 /arsaveLast — every sessionWrite journal + palace consolidation + awareness compounding + semantic prefetch.
/arsaveallEnd of day (multi-session)Batch save all parallel sessions — scan, merge, deduplicate, done.
/arbootstrapFirst install / migratingScan your machine for existing projects and import them.

Without /arstatus, a fresh agent has zero orientation. Without /arsave, nothing compounds. These two are the entire loop.


🌙 Dreaming — Nightly Consolidation (optional)

An autonomous overnight agent that runs while you sleep and compounds everything your sessions wrote during the day.

What it doesResult
Mine patterns across all projectsRepeated corrections promote to palace/awareness
Ebbinghaus salience decayLow-signal rooms fade; your palace stays sharp
Journal rollupsEntries >30 days compress into summary rooms

Telegram reportNightly summary: learned · decayed · crystallized

Requires a live Claude Code login. If the session expires, dream skips with a Telegram alert.

Dream reports are saved locally to ~/.agent-recall/dreams/YYYY-MM-DD.md.


🖥️ War Room Dashboard — Download & Deploy

A local-first visual dashboard for your memory: an activity calendar, per-project status, corrections, and insights — all rendered from your local ~/.agent-recall/ data. Fully offline (vendored assets), no Node and no build step.

<p align="center"> <img src="warroom/static/preview.png" alt="AgentRecall War Room — Overview" width="900"> </p>
  1. Download ar-warroom-v3.4.32.zip from the latest GitHub Release.
  2. Unzip it, then serve it locally:
cd warroom
python3 -m http.server 8080
  1. Open http://localhost:8080/AgentRecall.html

This is the recommended onboarding for Hermes / OpenClaw / OpenCode users too — one offline page to see everything your agent has learned.


Architecture

TypeScript monorepo, 4 published packages: core (storage + tool logic), mcp-server (thin MCP wrappers), sdk (programmatic API), cli (the ar command). All memory is local markdown under ~/.agent-recall/projects/<slug>/journal/, corrections/, and palace/ (rooms, skills, pipeline, awareness). An optional Supabase mirror adds pgvector semantic recall; all-local stays the default.
