Home Lab Context MCP

A small, storage-backed Model Context Protocol server for sharing durable project context between trusted coding agents. It is designed for a private network or another controlled environment; it is not a public data-sharing service.

What it provides

• Project and safe-text-file discovery.

• Read operations with ETags for optimistic concurrency.

• Writes limited to context/ and handoffs/.

• Timestamped handoffs for agent-to-agent continuity.

• No delete operation.

The MCP is deliberately shared memory. Private chat history remains with each agent; only explicit project context is shared.

Security model

The server deliberately rejects path traversal, secret-like names, unsupported file types, and oversized requests. Deploy it behind an authenticated ingress, use least-privilege storage credentials, and never store secrets in shared context. See the threat model.

Repository status

This repository contains the reusable authenticated HTTP MCP server, its S3-compatible context store, optimistic concurrency, and timestamped handoffs. It contains no private endpoint, credential, network, or cluster configuration.
