codemcp

Name: codemcp MCP Server
Author: ezyang

Minimal MCP coding agent for Claude Desktop — read/write/run, nothing else.

codemcp turns Claude Desktop into a usable coding agent without paying for Claude Code. It exposes just enough to be productive: a file reader/writer, a shell runner, and a project init step. Designed to be small, auditable, and easy to bring your own restrictions.

Warum nutzen

Hauptfunktionen

Tiny surface area: ReadFile, WriteFile, EditFile, RunCommand, InitProject
Project-scoped config in codemcp.toml per repo — defines allowed commands
Auto-commit per change so you always have a git checkpoint
Single-file install via uvx codemcp
Claude Desktop becomes a real IDE-replacement for free-tier coding

Installieren

Wählen Sie Ihren Client

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "codemcp": {
      "command": "uvx",
      "args": [
        "codemcp"
      ]
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "codemcp": {
      "command": "uvx",
      "args": [
        "codemcp"
      ]
    }
  }
}

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "codemcp": {
      "command": "uvx",
      "args": [
        "codemcp"
      ]
    }
  }
}

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "codemcp": {
      "command": "uvx",
      "args": [
        "codemcp"
      ]
    }
  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "codemcp",
      "command": "uvx",
      "args": [
        "codemcp"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

{
  "context_servers": {
    "codemcp": {
      "command": {
        "path": "uvx",
        "args": [
          "codemcp"
        ]
      }
    }
  }
}

In context_servers hinzufügen. Zed lädt beim Speichern neu.

claude mcp add codemcp -- uvx codemcp

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: codemcp

Use Claude Desktop as a free Claude Code replacement

👤 Devs on Claude Pro (not Max) who want agentic coding ⏱ ~15 min intermediate

Wann einsetzen: You don't want to pay for Claude Code but want the same loop in Desktop.

Voraussetzungen

Server/skill installed and authenticated — See repo README

Ablauf

Init a project

Initialize codemcp in /repos/my-project. Whitelist pytest and ruff only.✓ Kopiert

→ codemcp.toml written with those two commands
Iterate

Add a /healthz endpoint and a test for it. Run pytest after.✓ Kopiert

→ File edits + green test output, auto-committed

Ergebnis: Coding-agent workflow in plain Claude Desktop — every step a git commit.

Fallstricke

RunCommand only runs what's whitelisted in codemcp.toml — RunCommand only runs what's whitelisted in codemcp.toml — list every command you'll need upfront.

Fehlerbehebung

Häufige Fehler und Lösungen

command not in allowlist

Add the command to codemcp.toml under [commands] before asking Claude to run it.

Prüfen: cat codemcp.toml

edit didn't match

EditFile uses exact match. Read the file first and copy the exact old string including whitespace.

Prüfen: ReadFile and compare

Alternativen

codemcp vs. andere

Alternative	Wann stattdessen	Kompromiss
