Basic Memory Teams is now available!
Give your team a single, shared cloud workspace. Knowledge isn't confined to one person — anything a teammate writes is immediately available to everyone else and to their AI assistants.
Edit a note together in real time, hand work off between humans and agents, and build one connected knowledge base instead of scattered copies. Same pricing - start with one user and add more as needed.
Basic Memory
Your AI never forgets again.
Pick up right where you left off — in Claude, Codex, Cursor, ChatGPT, or
anything that speaks MCP. Your knowledge
lives as Markdown files that both you and your AI can read, write, and
search.
- Local-first. Plain text on your disk. Forever.
- Two-way. AI and humans write to the same files; sync keeps them in step.
- A real knowledge graph. Observations and wikilinks compound into context.
- Semantic search. Find notes by meaning, not just keywords, with optional
cross-encoder reranking for higher-quality vector and hybrid results.
- MCP-native. Works with every major AI client and IDE.
- Progressive tool discovery. Every tool is tagged with behavior hints
(read-only, destructive, idempotent) so agents pick the right tool on
demand — no wasted context trying things to see what they do.
- Cloud, optional. Sync across devices when you want — never required.

uv tool install basic-memory --prerelease=allow
--prerelease=allow is required: Basic Memory 0.23 depends on a FastMCP 4
pre-release, and uv only accepts pre-releases of transitive dependencies when
told to — without the flag it silently installs an older release. The same flag
goes on every uvx / uv tool upgrade command below.
For Postgres deployments that store semantic vectors in Milvus, install the
first-party optional extra instead:
uv tool install "basic-memory[milvus]" --prerelease=allow

What people are saying
Basic Memory changed my whole relationship with LLMs. I switched from GPT
and Gemini to exclusively Claude and Claude Code because of this
integration and am completely revamping all our company's processes around
a Basic Memory workflow.
— Alex, TrainerDay
Basic Memory is the missing 'wow' factor in AI chatbots. Now I can't
imagine Claude or Claude Code without it.
— Caleb, Caleb Picker Consulting
I don't code without Basic Memory anymore. It's such a time saver to be
able to refer to projects I don't currently have active and keep a running
log of all my learnings and ProTips.
— @groksrc, Developer

Official agent packages
This repository is also the canonical home for Basic Memory's host-native
agent packages. The core Python package, Claude Code plugin, shared skills,
Hermes plugin, and OpenClaw plugin all ship from the same source tree.
Maintainers can verify the whole consolidated surface from the repo root:
just package-check
Package-local justfiles are also available when working inside one host:
just package-check-claude-code
just package-check-skills
just package-check-hermes
just package-check-openclaw
Claude Code plugin
The Claude Code plugin is the bridge between Claude's working memory and Basic
Memory — session-start briefings, pre-compaction checkpoints, an opt-in capture
output style, and /basic-memory:bm-setup · :remember · :share · :status.
Connect the Basic Memory MCP server first — see Connect your AI
client. The plugin's hooks and skills call it, so it's a
hard prerequisite. Then install the plugin:
bm install claude-code
That registers the marketplace and installs the plugin through Claude Code. Add
--scope project to declare both in the repository's settings for a team, or
--dry-run to see the underlying claude plugin commands without running them.
Source: plugins/claude-code.
Shared skills
Framework-agnostic SKILL.md files live in skills/. If your
Skills CLI supports repository subdirectory sources:
npx skills add basicmachines-co/basic-memory/skills -g
For Claude and ChatGPT, upload basic-memory.zip or basic-memory-chatgpt.zip
from the skills-latest
release; see skills/README.md.
If your installed Skills CLI cannot load that source, update the CLI or copy
the memory-* directories from skills/ into your agent's skills directory.
Hermes
Hermes keeps its native plugin shape under integrations/hermes:
hermes plugins install basicmachines-co/basic-memory/integrations/hermes
Hermes does not install a plugin's Python dependencies, so also add the mcp
package to the Hermes venv — see the plugin README
for that step and the supported Hermes releases.
OpenClaw
OpenClaw stays package-native and publishes from
integrations/openclaw:
openclaw plugins install @basicmemory/openclaw-basic-memory
Pick up where you left off

Connect your AI client
If you went the Cloud route, the web app walks you through
client connect. The snippets below are for local installs.
Claude Desktop
Edit ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"basic-memory": {
"command": "uvx",
"args": ["--prerelease=allow", "basic-memory", "mcp"]
}
}
}
Restart Claude Desktop. Notes live in ~/basic-memory by default.
Claude Code
claude mcp add basic-memory -- uvx --prerelease=allow basic-memory mcp
For the full memory bridge — session briefings, pre-compaction checkpoints, and
the /basic-memory:* commands — also install the Claude Code
plugin on top of this.
Codex CLI
Add to ~/.codex/config.toml:
[mcp_servers.basic-memory]
command = "uvx"
args = ["--prerelease=allow", "basic-memory", "mcp"]
Codex can keep its default MCP approval behavior, or you can pre-approve eligible
Basic Memory tools by adding this server-scoped setting to the same table:
[mcp_servers.basic-memory]
command = "uvx"
args = ["--prerelease=allow", "basic-memory", "mcp"]
default_tools_approval_mode = "approve"
This does not disable Codex approvals globally or expand which Basic Memory
projects the server can access. Codex still requires approval for tools that
advertise a destructive annotation, including Basic Memory's writes, edits, and
deletes. If you installed the Basic Memory Codex plugin, use its
plugin-scoped configuration instead.
Cursor
Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):
{
"mcpServers": {
"basic-memory": {
"command": "uvx",
"args": ["--prerelease=allow", "basic-memory", "mcp"]
}
}
}
VS Code
Add to your User Settings (JSON):
{
"mcp": {
"servers": {
"basic-memory": {
"command": "uvx",
"args": ["--prerelease=allow", "basic-memory", "mcp"]
}
}
}
}
ChatGPT
Basic Memory exposes OpenAI-compatible search and fetch tools for Custom
GPT actions. See the ChatGPT integration
guide.
Obsidian
No setup. Point Obsidian at ~/basic-memory (or your project folder) and the
same wikilinks, frontmatter, and Markdown your AI writes appear in your graph
view. Edit either side — sync handles the rest.
Try a prompt:
"Create a note about our project architecture decisions."
"Find information about JWT auth in my notes."
"What have I been working on this week?"
What's New
- Automatic updates. Basic Memory keeps itself up to date for
uv tool
and Homebrew installs; bm update triggers a manual check.
- Semantic vector search. Find notes by meaning, not just keywords.
Hybrid full-text + vector ranking with FastEmbed embeddings, on SQLite or
Postgres.
- Optional search reranking. Rescore the strongest vector and hybrid
candidates with a local FastEmbed cross-encoder or a LiteLLM-backed provider.
- Schema system. Infer, validate, and diff the structure of your
knowledge base with
bm_schema(command="infer"), bm_schema(command="validate"), and
bm_schema(command="diff").
- Per-project cloud routing. Route individual projects through the cloud
while others stay local, via API key (
bm project set-cloud).
- Explicit note changes.
bm_edit updates existing notes; bm_write
creates notes and guards against accidental overwrites.
- Richer search results. Matched chunk text is included so the LLM gets
context, not just hits.
- FastMCP 3.0 + tool annotations. Every tool ships with MCP behavior
hints (
readOnlyHint, destructiveHint, idempotentHint,
openWorldHint) so agents can discover capabilities progressively at
runtime instead of guessing or burning tokens.
- CLI overhaul.
--json output for scripting, workspace-aware commands,
and an htop-inspired project dashboard.
Full CHANGELOG for v0.18 → v0.20.
Optional cross-encoder reranking
Reranking adds a second relevance pass after vector or hybrid retrieval. It is
disabled by default because it adds inference latency and, for the local
provider, a first-run model download. Text, title, and permalink searches keep
their existing ranking.
Enable the default local FastEmbed reranker:
export BASIC_MEMORY_RERANKER_ENABLED=true
The default model is jinaai/jina-reranker-v1-tiny-en. To use a hosted
reranker through LiteLLM instead, first install the optional LiteLLM
SDK, then configure it:
export BASIC_MEMORY_RERANKER_ENABLED=true
export BASIC_MEMORY_RERANKER_PROVIDER=litellm
export BASIC_MEMORY_RERANKER_MODEL=cohere/rerank-v3.5
export COHERE_API_KEY=...
The feature fails fast on invalid configuration and does not silently fall
back to retrieval order when an enabled provider fails. See the
semantic search guide for
provider setup, all settings, tuning, pagination, and failure behavior.
Why Basic Memory
Most LLM conversations are ephemeral. You ask a question, get an answer, then
everything is forgotten. Workarounds have limits:
- Chat history captures conversations but isn't structured knowledge.
- RAG lets the LLM query your documents but not write back to them.
- Vector DBs need complex infra and usually live in someone else's cloud.
- Knowledge graphs need specialized tooling to maintain.
Basic Memory takes a simpler path: structured Markdown files that humans
and LLMs both read and write.
- All knowledge stays in plain files you control.
- Both sides read and write to the same files.
- Familiar Markdown with semantic patterns — no new format to learn.
- A traversable graph the LLM can follow link by link.
- Works with the editors you already use (Obsidian, VS Code, anything).
- Just files plus a local SQLite index. No servers required.
How it works
You're chatting normally about coffee:
I've been experimenting with brewing methods. Pour over gives more clarity
than French press, water at 205°F seems best, and freshly ground beans
make a huge difference.
Ask the LLM to capture it:
"Make a note on coffee brewing methods."
A Markdown file appears in your project directory in real time:
---
title: Coffee Brewing Methods
permalink: coffee-brewing-methods
tags: [coffee, brewing]
---
# Coffee Brewing Methods
## Observations
- [method] Pour over highlights subtle flavors over body
- [technique] Water at 205°F (96°C) extracts optimal compounds
- [principle] Freshly ground beans preserve aromatics
## Relations
- relates_to [[Coffee Bean Origins]]
- requires [[Proper Grinding Technique]]
- affects [[Flavor Extraction]]
Next session, the LLM picks up the thread. It follows the relations to
surface what you already know about Ethiopian beans and burr grinders, and
builds on it instead of starting over. You see the same files in Obsidian or
your editor. Edit them by hand — the AI sees your changes too.
Real two-way flow: humans edit Markdown, LLMs read/write through MCP, sync
keeps everything consistent, and the source of truth is always your files.
The Markdown format
Each file is an Entity. Entities have Observations (facts about them) and
Relations (links to other entities). That's the whole grammar.
Frontmatter
---
title: <Entity title>
type: note
permalink: <uri-slug>
tags: [optional, list]
---
Observations
Facts about the entity. Categories in [brackets], tags with #, optional
context in parens.
- [method] Pour over highlights subtle flavors
- [tip] Grind medium-fine for V60 #brewing
- [fact] Lighter roasts contain more caffeine than dark
- [resource] James Hoffmann's V60 technique on YouTube
- [question] How does temperature affect compound extraction?
Relations
Wiki-style links that form the graph. Single-token relation types, or quote
multi-word ones.
- pairs_well_with [[Chocolate Desserts]]
- grown_in [[Ethiopia]]
- requires [[Burr Grinder]]
- "pairs well with" [[Dark Chocolate]]
Bare - [[Target]] and prose - Worth checking out [[Target]] index as
links_to. Full reference in the
docs.
MCP tools
Basic Memory exposes these tools to any MCP client. Every tool is annotated
with MCP behavior hints (read-only, destructive, idempotent, open-world) so
agents can pick the right one without trial-and-error:
- Content:
bm_write, bm_read, bm_edit, bm_move, bm_delete
- Search & discovery:
bm_search, bm_list, bm_find
- Knowledge graph:
bm_context
- Projects:
bm_project(command="list" | "create" | "recent");
bm_project_delete is separate and requires server opt-in.
- Schema:
bm_schema(command="validate" | "infer" | "diff")
- Manual:
bm_man
- Cloud connector adapters:
search and fetch are registered by Cloud only.
Local diagnostics use bm doctor.
Most tools default to text; bm_context defaults to JSON. Pass
output_format="json" for structured responses. Project-scoped tools accept a
name, workspace/project, or external UUID through project.
Use bm_man(page="bm-search(3)") for the installed contract, or see the
tool guide. CLI commands retain their shell names.
CLI essentials
# Projects
basic-memory project list
basic-memory project add research ~/research
basic-memory project set-cloud research # route through cloud
basic-memory project set-local research # revert
# Config
basic-memory config list # all settings, effective values, env overrides
basic-memory config set cli_output_style plain # validated through the config model
basic-memory config unset cli_output_style # revert to default
# Health & maintenance
basic-memory status
basic-memory doctor # report project problems and the commands that fix them
basic-memory tool edit ... # CLI access to MCP tools
basic-memory update # check for and install updates
# Imports
basic-memory import claude conversations
basic-memory import chatgpt
basic-memory import memory-json
Routing flags (--local / --cloud) force a target when you're in mixed
mode. Full CLI reference in the
docs.
Auto-updates
CLI installs check for updates every 24 hours by default and apply them
silently (so the MCP server keeps responding).
- Supported install sources:
uv tool, Homebrew
- Skipped for
uvx (ephemeral runtime managed by uv)
- Manual:
bm update (check + apply) or bm update --check (check only)
Disable in ~/.basic-memory/config.json:
{ "auto_update": false }
Telemetry
Minimal, anonymous events to understand the CLI-to-cloud conversion funnel.
What we collect: cloud promo impressions, cloud login attempts and
outcomes, promo opt-out events.
What we don't: file contents, note titles, knowledge base data, PII, IP
addresses, per-command or per-tool tracking.
Events go to our Umami Cloud instance (open-source,
privacy-focused) on a background thread — never blocks the CLI.
Opt out:
export BASIC_MEMORY_NO_PROMOS=1
This disables promos and all telemetry.
Logging
Basic Memory uses Loguru. Defaults vary
by entry point:
| Entry point | Default | Why |
|---|
| CLI commands | File only | Doesn't interfere with command output |
| MCP server | File only | Stdout would corrupt JSON-RPC |
| API server | File (local) or stdout (cloud) | Docker/cloud uses stdout |
Log file: ~/.basic-memory/basic-memory.log (10MB rotation, 10 days
retention).
Environment variables
| Variable | Default | Description |
|---|
BASIC_MEMORY_LOG_LEVEL | INFO | DEBUG / INFO / WARNING / ERROR |
BASIC_MEMORY_CLOUD_MODE | false | API logs to stdout with structured context |
BASIC_MEMORY_FORCE_LOCAL | false | Force local API routing |
BASIC_MEMORY_FORCE_CLOUD | false | Force cloud API routing |
BASIC_MEMORY_EXPLICIT_ROUTING | false | Mark route selection as explicit |
BASIC_MEMORY_ENV | dev | Set to test for test mode (stderr only) |
BASIC_MEMORY_NO_PROMOS | false | Disable cloud promos and telemetry |
BASIC_MEMORY_IMPORT_UPLOAD_MAX_BYTES | 104857600 | Max uploaded import size |
BASIC_MEMORY_LOG_LEVEL=DEBUG basic-memory reindex
tail -f ~/.basic-memory/basic-memory.log
Development
