What It Is

Context Vault is a persistent memory layer for AI Coding Tools, designed to solve the problem of AI coding assistants “starting from scratch” across different sessions and tools. It works based on the MCP standard and, by default, stores decisions, patterns, notes, and context locally as plain Markdown, then automatically retrieves relevant content at the start of a new session.

Core Capabilities

Feature-wise, it covers automatic saving, session-start retrieval, cross-tool sharing, project namespaces, hybrid semantic and full-text search, recall tracking, team vaults, the Vault-brain 3D knowledge graph, and Agent rules. Its supported ecosystem mainly consists of MCP-compatible AI clients, with the page explicitly listing Claude Code, Cursor, Windsurf, Zed, VS Code, and Raycast. The product is open source under the MIT License, and can be self-hosted, audited, and extended, reducing the risk of data lock-in. At the API/interface level, it provides CLI commands as well as MCP tools such as get_context, save_context, list_context, and session_start.

Pricing

Local vaults are free and unlimited, with no account required. The Free cloud account costs $0 and includes 10K hosted entries, 1GB storage, 5,000 requests/day, multi-device sync, and import/export. Pro is $9/month, increasing the limits to 50K entries, 10GB storage, and unlimited requests, while adding a recall dashboard, Vault-brain, visibility controls, and priority support. Team starts at $29/month and includes 3 seats; additional seats are $9/seat/month. It provides team vaults, member management, audit logs, SSO, and dedicated support.

Pros and Cons

The main advantages are its local-first design, plain-text Markdown storage, MIT open-source licensing, and strong MCP compatibility, making it well suited for migrating context across tools such as Cursor and Claude Code. The free tier is also fairly generous. The downsides are that its value depends on the MCP ecosystem and on how well knowledge is organized; the documentation also emphasizes that the design of kind, tags, and folders affects retrieval quality. Advanced insights and team features require a paid plan.

Who It’s For and Access from China

It is suitable for individual developers, indie developers, multi-project consultants, and teams that use AI coding assistants over the long term and need to share architectural decisions. The scraped text does not specify access from China, localized payment options, or alternatives. Stripe is the only payment method observed, and network accessibility should be verified through actual testing.
