Context Book
Persist and inject the right project context into Claude Code or Cursor so agents stop asking you to re-explain stack, decisions, and constraints.
Overview
Context Book is a MCP server for the Build phase that delivers project and session context to agents on demand instead of requiring you to re-explain it every time.
What is this MCP server?
- Hosted streamable-http MCP remote on Railway—no local server required for basic use
- Registry title Context Book—positions persistent context as a first-class agent resource
- Stops repeat explanations by serving context when the agent needs it, not on every turn
- Pairs with any MCP-capable client via official Model Context Protocol registry entry
- Version 1.0.2 with companion web app at context-book-production.up.railway.app
- Registry version 1.0.2
- Remote type streamable-http at context-book-mcp-production.up.railway.app
- Publisher CLI meta version 1.0.1

What problem does it solve?
Every new agent thread starts cold, so you waste cycles re-stating stack choices, conventions, and open decisions.
Who is it for?
Indie devs running Claude Code or Cursor daily on one product who want a single maintained context layer across sessions.
Skip if: Teams that already enforce full-repo indexing in the IDE and never use external MCP context stores.
What do I get? / Deliverables
After you register Context Book and seed context, agents can pull the right background during tasks without you repeating the same briefing.
- Registered MCP server connection in your agent config
- Reusable context payloads agents can fetch during coding tasks
- Less repeated manual briefing in multi-session workflows

Journey fit
Context plumbing is where solo builders wire agents into real repos—after idea/validate, during active build and every later iteration. agent-tooling is the canonical shelf for MCP servers that manage memory, prompts, and session context rather than shipping UI or infra.
How it compares
MCP context store and remote server, not an in-repo Agent Skill markdown pack.
Common Questions / FAQ
Who is Context Book for?
Solo and indie builders using MCP-enabled agents who need persistent, selective context without re-pasting notes each session.
When should I use Context Book?
Use it once you are actively building or iterating with agents and notice repeated explanations about architecture, APIs, or product rules.
How do I add Context Book to my agent?
Add the registry MCP server io.github.aditya201551/context-book-mcp and point your client at the streamable-http remote https://context-book-mcp-production.up.railway.app per your tool’s MCP config.
