Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server ContextLib for Claude on this computer, in this order: 1) Check Docker with docker --version. If it is missing, tell me to install it from https://www.docker.com/products/docker-desktop/; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "agentbrain-contextlib": { "command": "docker", "args": [ "run", "-i", "--rm", "ghcr.io/willykeenan/agentbrain-contextlib:0.1.0", "mcp", "--identity", "{identity}" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the ContextLib tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Common questions

Is ContextLib safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

ContextLib

A project library that outlives every agent session.

Real screenshot of the sample library (an invented project).

A ctxlib session: an owner's decision lands current, an agent's lesson waits in the inbox, a secret is refused, and doctor passes.

Each project's knowledge — decisions, requirements, facts, lessons, glossary, sources and returned work — is stored as plain Markdown files with a small front-matter block, in one folder per project. The folders can sit on an external SSD. A person can understand a project from Finder alone. Agents read and write the same files through a CLI (ctxlib) and an MCP server (context_* tools). Any database is a search index rebuilt from the files, never the source of truth.

It is the open core of the context plugin of AgentBrain.

The Python package is agentbrain_contextlib. The CLI is ctxlib. Python 3.9+, standard library only. Git is optional.

Why

Agent sessions end. Chat logs drift. A store that only a model can parse is a dead end the first time you open Finder on an airplane.

ContextLib keeps the durable layer as files you can read, diff, copy, and take to another Mac. The search index is disposable. The Markdown is the product.

60-second quickstart

pip install "git+https://github.com/willykeenan/agentbrain-contextlib"

ctxlib init ~/ContextLib --project lighthouse-app \ --name "Lighthouse App" \ --purpose "Harbor dashboard for lamp status, fog signals, and traffic"

ctxlib add lighthouse-app decision "Use keeper logs as lamp status" \ --body "Decision: Lamp status comes from keeper logs, not AIS." \ --author mara \ --tag lamp --tag keeper-log

ctxlib brief lighthouse-app ctxlib doctor lighthouse-app --ten-minute

The library path is --library PATH, else env CONTEXTLIB_ROOT, else ~/ContextLib.

A finished sample you can open in Finder without installing anything lives at examples/sample-library/. Start at that README, then the project BRIEF, then decisions/INDEX.md.

Full walkthrough: docs/QUICKSTART.md.

CLI (`ctxlib`)

ctxlib [--library PATH] COMMAND

Command	What it does
`init PATH [--project SLUG --name NAME --purpose TEXT]`	Create a library (and optionally the first project)
`project add SLUG NAME [--purpose]`	Add a project folder
`project list`	List projects
`add PROJECT TYPE TITLE (--body TEXT \	--body-file F) --author ID [options]`	Write a record (`--evidence`, `--tag`, `--review-by`, `--approved-by`)
`get PROJECT ID`	Print one record, with evidence state and supersession chain
`search PROJECT QUERY [--type] [--all]`	Search the rebuildable index
`brief PROJECT`	Print the always-loaded summary (≤ 8192 bytes)
`supersede PROJECT OLD NEW --reason TEXT --author ID`	Mark old superseded, move the file, keep the body hash
`review PROJECT ID confirm\	retire --note TEXT --author ID`	Confirm or retire a record
`inbox PROJECT`	List proposed records
`accept PROJECT ID --author ID`	Move inbox → current
`reject PROJECT ID --reason TEXT --author ID`	Move inbox → rejected
`due PROJECT`	Records whose `review_by` is due
`regen PROJECT\	--all`	Rewrite BRIEF, INDEX, GLOSSARY, TIMELINE, README
`rebuild`	Rebuild the SQLite search index from files
`capture PROJECT RESULT.json`	Turn a result file into a `return` (and proposed lessons)
`import-md PROJECT FILE --type TYPE --author ID`	Markdown file → record
`export PROJECT OUT_DIR [--include-private]`	Zip a project
`import BUNDLE`	Import a zip
`doctor [PROJECT] [--ten-minute]`	Plain-English health check
`sync`	`git pull` / `git push` when the library is a git repo; otherwise a no-op with a message
`mcp --identity ID`	Stdio MCP server; the identity is fixed for the process

Types: decision, requirement, fact, lesson, glossary, source, return, brief-note.

MCP (`context_*` tools)

ctxlib mcp --identity ID is a stdio JSON-RPC server. Protocol versions: 2024-11-05, 2025-03-26, 2025-06-18.

Tools: context_brief, context_search, context_get, context_record, context_supersede, context_review_due, context_review, context_capture, context_export, context_import, context_status.

The identity is fixed at start. Tools cannot write as another identity. Errors come back as isError results.

Details: docs/MCP.md.

Record format

A record is UTF-8 Markdown. It starts with a YAML-like front-matter block (scalars, quoted strings, lists of scalars, lists of flat maps) and a Markdown body. The body hash is stored in the front-matter; bodies are not rewritten.
