The project cites Microsoft Security's identification of 50 memory poisoning attempts across 31 companies in 60 days as of February 2026, and notes that GPT-5.4 showed an 87.5% injection success rate. Phase 1 runs entirely locally with zero LLM or network calls in the analyzer, installed via npm install -g @th0t3p/m8m.", "body_md": "AI memory observability, provenance & security. Eight eyes. Nothing gets past.\n\nm8m monitors what your AI agents remember about you — where each memory came from, what changed, and whether anything looks suspicious. The core pieces share one local SQLite database:\n\n- **MCP server** — live memory operations as your agent works\n- **File watcher** — tracks local memory files (`MEMORY.md` ,`CLAUDE.md` , …);\nit runs automatically inside the MCP server (and can also run standalone via`m8m watch` )\n- **Security analysis** — pattern-based scanning of every memory for\ncredentials, instructions, URLs/emails, and hidden characters\n- **Snapshots & rollback** — point-in-time baselines to diff drift and roll back\n- **CLI** — query and audit memory state from the terminal\n- **Local dashboard** — a dark, browser-based visualization\n\nPhase 1 is entirely local: SQLite storage, pattern-based analysis, and **zero**\nLLM or network calls in the analyzer itself.\n\nYour AI remembers everything about you — preferences, habits, work patterns, relationships. But do you know what it remembers? Can you tell if those memories have been tampered with?\n\n- Microsoft Security identified **50 memory poisoning attempts** across 31\ncompanies in just 60 days (Feb 2026)\n- A single email can silently rewrite your AI agent's memory\n([MemGhost, Jul 2026](https://arxiv.org) )\n- More capable models are **more vulnerable** , not less — GPT-5.4 showed\n87.5% injection success rate\n\nm8m gives you visibility and control. Think of it as `git log` for your\nAI's memory.\n\n```\nnpm install -g @th0t3p/m8m\n./scripts/install.sh\n```\n\nThat installs dependencies, builds, and runs `npm link` so `m8m` is on your\n`PATH`. (Equivalent manual steps: `npm install` then `npm install -g .`.)\n\n```\nnode dist/cli/index.js --help\nnpx tsx src/cli/index.ts --help\n```\n\nThe first command requires `npm run build` first; the second runs TypeScript\ndirectly with no build.\n\n**Data location:** everything lives in `~/.m8m/` by default. If `~` is\nread-only (e.g. some sandboxes), set `M8M_HOME` to a writable directory:\n`export M8M_HOME=/path/to/m8m-data`.\n\n```\nm8m init\nm8m import ./MEMORY.md --platform local_file\nm8m status\nm8m list --flagged\nm8m audit\n```\n\n| Command | Description | \n|---|---|\n| `m8m init` | Initialize config + database | \n| `m8m status` | Overview of agent + file memories, flags, security events | \n| `m8m list [--platform

Statuses:\n\n| State | How | Reversible? | What's kept | \n|---|---|---|---|\n| **active** | default | — | row + full changelog | \n| **quarantined** | `m8m quarantine ` (or dashboard) | yes — `m8m restore ` | row + full changelog | \n| **dismissed** | `m8m dismiss ` | yes | row, flags cleared | \n| **deleted** (soft) | `m8m_delete` MCP tool /`m8m clear` | yes (status only) | row + content + changelog | \n| **purged** (hard) | `m8m purge --force` | **no** | removed: row, changelog, security events | \n\nSoft-delete keeps the content so it can be restored or audited. Purge physically removes the row and its history (earlier snapshots may still hold a copy).\n\nSnapshots are point-in-time dumps of **both kinds of memory** — agent memories\nand file memories — so you can diff drift and roll back the whole store\natomically.\n\n- **Auto-snapshots** run inside the MCP server every`auto_snapshot_interval_minutes` (default 60), so a recent baseline is always\navailable while a client is connected.\n- `m8m snapshot` takes one manually.\n- `m8m diff` compares the current store against the latest snapshot (or two\nsnapshots, or a time window).\n\n**Rollback always previews first, then asks to confirm:**\n\n```\nm8m rollback # shows restore/revert/remove preview, then [y/N]\nm8m files rollback # shows a line diff, then restores the previous version\n```\n\nRollback is traceable — it writes normal changelog/version entries, so you can\nroll forward again. Snapshot rollback re-adds deleted agent memories, reverts\nmodified ones, soft-deletes memories added after the snapshot, restores file\nmemories to their snapshot content, and purges file memories added since.\n`m8m files rollback ` rolls a single file back one version instead.\n\nm8m exposes `m8m_store`, `m8m_search`, `m8m_recent`, `m8m_status`,\n`m8m_flag`, and `m8m_delete` over stdio. (`m8m_delete` is a reversible\nsoft-delete; hard deletion is `m8m purge` in the CLI.)\n\n**The MCP server also runs the file watcher.** While any client is connected,\nit watches your memory files (`watch_paths`, scan-provider targets, and every\nfile already imported) and re-imports changes as a new version with a stored\ndiff — so you don't need to run `m8m watch` separately. `m8m watch` remains\navailable for standalone/foreground use.\n\n```\nm8m mcp add codex\n```\n\nReplace `codex` with `claude`, `cursor`, or `dsh`.\n\nThis writes the right config entry into the client's config file for you\n(Codex `~/.codex/config.toml`, Claude `~/.claude.json`, Cursor\n`~/.cursor/mcp.json`, DSH `$DSH_HOME/cordis.patch.yml`). Add\n`--data-dir /path` to bake in a `M8M_HOME` override.\n\nOr use your client's native command:\n\n```\ncodex mcp add m8m -- npx -y @th0t3p/m8m mcp\nclaude mcp add m8m -- npx -y @th0t3p/m8m mcp\n```\n\nThe server is fetched from npm on demand via `npx`, so no clone or build is\nneeded.\n\n**OpenAI Codex** — `~/.codex/config.toml`:\n\n```\n[mcp_servers.m8m]\ncommand = \"npx\"\nargs = [\"-y\", \"@th0t3p/m8m\", \"mcp\"]\nstartup_timeout_sec = 30\n```\n\nTools appear as `m8m_store`, etc.\n\n**Claude Code** — project scope `.mcp.json`, or user scope `~/.claude.json`:\n\n```\n{\n \"mcpServers\": {\n \"m8m\": { \"command\": \"npx\", \"args\": [\"-y\", \"@th0t3p/m8m\", \"mcp\"] }\n }\n}\n```\n\nTools appear as `m8m_store`, etc.\n\n**Cursor** — `~/.cursor/mcp.json`:\n\n```\n{\n \"mcpServers\": {\n \"m8m\": { \"command\": \"npx\", \"args\": [\"-y\", \"@th0t3p/m8m\", \"mcp\"] }\n }\n}\n```\n\n**DeepSeek Harness (DSH)** — `$DSH_HOME/cordis.patch.yml`:\n\n```\n- insert:\n - id: mcp-m8m\n name: '@deepseek-ai/dsh-mcp-client'\n config:\n serverName: m8m\n transport: stdio\n command: npx\n args: ['-y', '@th0t3p/m8m', 'mcp']\n```\n\nTools appear as `mcp__m8m__m8m_store`, etc.\n\n```\nm8m dashboard\n```\n\nThen open [http://localhost:8808](http://localhost:8808).\n\nFour views: **Timeline**, **Memories**, **Security**, and **Diff**. The Memories\nview shows both kinds of memory together — **agent memories** (facts stored via\nthe MCP server) and **file memories** (imported markdown/json files).\n\nConfig lives at `~/.m8m/config.json` (override the directory with `$M8M_HOME`).\nIt has two lists that control where m8m looks for vendor memory files:\n\n- **`providers`** — the agent harnesses` m8m scan` discovers. Each entry names\na vendor and lists the files/directories that hold its memories.\n- **`watch_paths`** — the paths the file watcher (inside the MCP server, or` m8m watch` ) monitors for changes in real time.\n\n```\n{\n \"db_path\": \"~/.m8m/m8m.db\",\n \"watch_paths\": [\n \"~/.claude/memories\",\n \"./.claude/MEMORY.md\",\n \"./.cursor/memory\",\n \"./AGENTS.md\",\n \"./MEMORY.md\",\n \"~/.codex/memories\",\n \"~/.hindsight\",\n \"~/.basic-memory\"\n ],\n \"providers\": [\n {\n \"name\": \"Claude Code\",\n \"platform\": \"claude_code\",\n \"targets\": [\n { \"path\": \"~/.claude/CLAUDE.md\", \"description\": \"User-level instructions\" },\n { \"path\": \"~/.claude/memories\", \"description\": \"User memories directory\", \"isDir\": true, \"extensions\": [\".md\", \".json\", \".txt\"] },\n { \"path\": \"./CLAUDE.md\", \"description\": \"Project-level instructions\" }\n ]\n },\n {\n \"name\": \"Codex\",\n \"platform\": \"local_file\",\n \"targets\": [\n { \"path\": \"~/.codex/memories\", \"description\": \"Native memory directory\", \"isDir\": true, \"extensions\": [\".md\", \".json\", \".txt\"] },\n { \"path\": \"~/.codex/AGENTS.md\", \"description\": \"Global agent rules\" }\n ]\n }\n ],\n \"dashboard_port\": 8808,\n \"auto_snapshot_interval_minutes\": 60,\n \"trust_levels\": {\n \"user_explicit\": 0.9,\n \"conversation\": 0.7,\n \"document\": 0.5,\n \"email\": 0.3,\n \"web_page\": 0.3,\n \"tool_output\": 0.5,\n \"ai_derived\": 0.4,\n \"unknown\": 0.1\n }\n}\n```\n\nA `providers` entry has:\n\n| Field | Type | Meaning | \n|---|---|---|\n| `name` | string | Vendor label recorded on each imported memory file (e.g. `\"Claude Code\"` ) | \n| `platform` | string | Provenance platform: `claude_code` ,`claude_desktop` ,`cursor` ,`local_file` , … | \n| `targets` | array | Files/directories to scan for this vendor | \n\nEach object in `targets` has:\n\n| Field | Type | Meaning | \n|---|---|---|\n| `path` | string | File or directory; `~` expands to your home dir,`./` is the project cwd | \n| `description` | string | Human-readable note shown by `m8m scan` /`m8m providers` | \n| `isDir` | boolean | `true` to scan a directory (default: treat as a single file) | \n| `extensions` | string[] | For `isDir` targets, only import these extensions (e.g.`[\".md\", \".json\"]` ) | \n\nAppend an object to the `providers` array in `~/.m8m/config.json`, then run\n`m8m scan`:\n\n```\n{\n \"name\": \"My Agent\",\n \"platform\": \"local_file\",\n \"targets\": [\n { \"path\": \"~/.my-agent/memories\", \"description\": \"My agent's memory dir\", \"isDir\": true, \"extensions\": [\".md\", \".json\"] }\n ]\n}\n```\n\nOr do it from the CLI without editing JSON:\n\n```\nm8m providers add \"My Agent\" \"~/.my-agent/memories\" --dir --ext .md,.json --desc \"My agent's memory dir\"\nm8m providers # list what's configured\nm8m providers rm \"My Agent\" # remove it\n```\n\n**Where the built-in defaults live:** the out-of-the-box vendor list for\n`m8m scan` is `src/core/providers.ts` in this repo; the `providers` array in\n`~/.m8m/config.json` **replaces** it, so you can trim or fully customize the\nlist.
