Claude Code MCP Integration

Give Claude Code Your Team's Context

Claude Code reads your CLAUDE.md — but that file lives in one repo and stops at ~100 useful lines. Connect Contextium over MCP and every session starts with your whole team’s knowledge: architecture, conventions, project state, tasks.

How the Claude Code Integration Works

1

Build Your Knowledge Base in Contextium

Move the context that outgrew your CLAUDE.md into Contextium libraries — architecture, conventions, decisions, runbooks, project phases and tasks. Keep a thin CLAUDE.md in the repo for repo-specific gotchas.

  • Architecture decisions and conventions
  • Cross-repo standards that per-repo files can’t hold
  • Project phases and tasks Claude Code can read and update
  • Everything versioned, with an event log

Connect Claude Code in 60 Seconds

Run the setup command and select Claude Code — it registers the MCP server and tool allow-list for you. Prefer doing it by hand? One command does the same:

Terminal (manual alternative)
claude mcp add contextium -- npx -y @contextium/mcp-server@latest

Every Session Starts Briefed

Claude Code loads relevant context from your workspace on demand — no pasting, no re-explaining, no 100-line ceiling. Resume a project and it knows which phase the team is on.

  • Relevance-based loading — only what the task needs
  • Same context in every repo, not one CLAUDE.md per repo
  • Teammates’ Claude Code sessions load the same knowledge
  • Project continuity: phases and tasks travel with the work

Beyond the CLAUDE.md Ceiling

A per-repo file was never going to carry a team.

CLAUDE.md alone

  • ✕One file per repo — copies drift apart
  • ✕~80–120 useful lines before adherence drops
  • ✕Loaded in full every session, relevant or not
  • ✕User-level files never reach teammates
  • ✕Nothing crosses repos or reaches other tools

With Contextium

  • One shared context across every repo
  • No size ceiling — loads by relevance
  • Update once, every teammate’s next session has it
  • Project phases and tasks Claude Code acts on
  • Same knowledge available in Cursor, Copilot and more

Claude Code Integration — Common Questions

How do I connect Contextium to Claude Code?

Run npx @contextium/mcp-server@latest setup and select Claude Code — it registers the MCP server and tool allow-list automatically. Or add it manually with claude mcp add contextium -- npx -y @contextium/mcp-server@latest.

Does Contextium replace my CLAUDE.md file?

It can coexist or replace it. The pattern that works best: keep a thin CLAUDE.md (~50 lines) for repo-specific build commands and gotchas, and put everything shared — architecture, conventions, decisions — in Contextium where every repo, tool, and teammate reaches it.

Can Claude Code update my context, not just read it?

Yes. Through the MCP tools Claude Code can create and update files, manage tasks, and progress project phases in your workspace — with every change versioned and logged.

Does this work with Claude Code’s auto memory?

Yes, they complement each other. Auto memory holds what your Claude Code learns for itself per project; Contextium holds what the whole team shares across projects and tools. See our guide on persistent context for Claude Code for the full layering.

Is the Claude Code integration free?

Yes. MCP integration is included in all Contextium plans, including the free individual plan.

Does it work with both the hosted and local MCP server?

Yes — connect via the hosted remote MCP endpoint (one URL, zero install) or run the local MCP server via npx. Both serve the same workspace context.
