Run this in your terminal

claude mcp add --transport http context-book https://context-book-mcp-production.up.railway.app

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Common questions

Is Context Book safe?

It passed 1 of 1 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Stop re-explaining yourself to Agents. Give it the right context, right when needed.

LLMs are stateless — each conversation starts from scratch. ContextBook gives your AI tools a persistent, searchable knowledge library to draw the right context when they need it. No bloatware, no pre-loaded junk. Just the right information, at the right time.

How It Works

flowchart LR

AI["🤖 AI Clients\nClaude · Cursor · Windsurf"] Browser["🌐 Browser Dashboard"] MCP["🔌 MCP Server :8081\n8 Bearer-authenticated tools"] API["⚙️ REST API :8080\nOAuth 2.0 · Books · Pages · Search"] DB["🗄️ PostgreSQL\npgvector · pg_trgm"] VOYAGE["🧠 Voyage AI\nvoyage-4 (1024-dim)"]

AI -- "MCP · Bearer Token" --> MCP Browser -- "Session · HTTP JSON" --> API MCP --- DB API --- DB API -- "OAuth 2.0 PKCE" --> AI DB --- VOYAGE

Two Go binaries share a PostgreSQL database:

API server (cmd/api) — the control plane: user login, OAuth 2.0, dashboard, book/page CRUD
MCP server (cmd/mcp) — the data plane: 8 MCP tools for AI agents, protected by Bearer tokens

MCP Tools

All tools require a valid Bearer token and are scoped to the authenticated user.

Tool	Description
`book_create_or_update`	Create a Book or update its metadata
`book_list`	Paginated list of Book metadata
`book_get`	Retrieve all pages of a Book
`page_insert`	Push an atomic page into a Book; embeds immediately
`page_update`	Replace a page's content; re-embeds
`page_delete`	Remove a page (indices not re-numbered)
`page_search`	Semantic search across all Books
`readme`	Returns the usage guide (call once per session)

Quick Start

Prerequisites

Go 1.26+
Node.js 22+
PostgreSQL 16+ with pgvector and pg_trgm
A Voyage AI API key

1. Set up the database

CREATE DATABASE contextbook_db;

\c contextbook_db CREATE EXTENSION IF NOT EXISTS vector; CREATE EXTENSION IF NOT EXISTS pg_trgm;

Migrations run automatically on API server startup.

2. Configure environment

cp .env.example backend/.env

Edit backend/.env — set DATABASE_URL, API_KEY_SALT, VOYAGE_API_KEY

3. Run the backend

cd backend

go run ./cmd/api/main.go # API + dashboard (:8080) go run ./cmd/mcp/main.go # MCP server (:8081)

4. Run the frontend (optional)

cd frontend

npm install && npm run dev # Vite dev server on :5173

5. Connect an AI client

For Cursor (.cursor/mcp.json):

"mcpServers": { "contextbook": { "url": "http://localhost:8081/mcp" } } }

For any MCP-compatible client, point the server URL to http://localhost:8081/mcp.
