Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

NPM package code-relay-mcp
Claude Code 
claude mcp add code-relay -- npx -y code-relay-mcp@3.1.0
Configuration JSON (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {

            "command": "npx",
            "args": [
                "-y",
                "code-relay-mcp@3.1.0"

Code Relay

English · Chinese

Build. Prove. Relay.

Code Relay lets your coding agent develop on one machine and prove the result on another.

Relay is an MCP-based coding-agent integration for cross-machine development and verification. AI on the Dev Host implements the request; the Target Host runs the real validation; a structured receipt comes back to guide the next repair iteration. It works with Codex, Claude Code, Cursor, VS Code, and other MCP-capable coding agents.

When Relay is useful

  • Different environments — develop on Windows or macOS, verify on Linux, a private network, or a production-like host.
  • Special hardware — send model code to a CUDA/GPU machine, or verify a camera, serial device, or sensor where it is connected.
  • Real integrations — exercise payment callbacks, queues, databases, browsers, or internal services that cannot be reproduced locally.
  • AI-driven iteration — return concrete expected/actual results so the coding agent can repair, republish, and retry.

What Relay provides

  • Branch-scoped project binding and short-lived join links.
  • Exact source-commit verification in an isolated worktree.
  • Checkpoint execution through a code-relay-checkpoint GitHub Actions self-hosted runner.
  • Safe, allowlisted validation commands with bounded output and timeouts.
  • Structured receipt.json and human-readable receipts for passed, failed, and blocked runs.

Quick start

AI client installation

Let your coding agent read and follow the instructions:

https://raw.githubusercontent.com/zarcherlot/code-relay/main/install.md
npm fallback
npx -y code-relay-mcp@latest install --client codex

Replace codex with claude-code, cursor, vscode, or generic as needed.

MCP server details

Code Relay is a local MCP server that communicates over stdio. The npm package starts the server with:

npx -y code-relay-mcp@3.1.0

The server implements the MCP JSON-RPC surface directly in Go (without a third-party MCP SDK). It supports initialize, ping, tools/list, and tools/call, and exposes these tools:

ToolPurpose
bind_projectBind a repository and branch to a relay role.
create_checkpoint_inviteCreate a short-lived checkpoint join link.
join_checkpointJoin a branch-scoped checkpoint subscription.
watcher_statusRead local watcher state.
stop_watcherStop the local watcher.
doctorRun non-mutating local health checks.
publish_runbookValidate and publish a runbook.
statusRead runbook and receipt status.
fetch_receiptLoad and validate a runbook receipt.
analyzeAnalyze a receipt and determine the next state.

The implementation and transport loop are in internal/relay/mcp.go.

How it works

the Dev Host sends a repository- and branch-bound runbook through Relay; the Target Host checks the exact source commit in its real environment and returns a Receipt recording the Checkpoint result.

Every runbook is bound to a repository, branch, and source commit. The Target Host acts as the Checkpoint, and the resulting receipt records passed, failed, or blocked verification for the next iteration.

Comment installer Code Relay ?

Il s'exécute sur votre machine. Dans Claude Code : claude mcp add code-relay -- npx -y code-relay-mcp@3.1.0. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.

Faut-il une clé API pour Code Relay ?

Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.

Code Relay est-il open source ?

Oui. Son code est sur GitHub sous licence MIT.

Qui maintient Code Relay ?

Il est publié par zarcherlot. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
