🚀 NEU: Universal MCP Installer v1.0.0 — Vollständige Neufassung von cursor-mcp-installer. Unterstützt jetzt 6 KI-Clients (Claude Desktop, Cursor, VS Code, OpenClaw, Claude Code, ChatGPT), ist plattformübergreifend (macOS, Windows, Linux), bietet echte MCP-Handshake-Validierung und ein gebrandetes Web-Dashboard. Aktualisiert auf MCP SDK 1.29.0.

🖥️ Web-Dashboard verfügbar! Starten Sie mit npx universal-mcp-installer --ui, um alles über eine visuelle Oberfläche zu verwalten. Siehe Verwendung des Dashboards unten.

Kurzanleitung

Schritt 1: Installieren Sie einen MCP-Server (Ein Befehl)

npx universal-mcp-installer install @modelcontextprotocol/server-memory

Das ist alles. Der Installer erkennt, welche KI-Clients Sie installiert haben, und schreibt die korrekte Konfiguration für jeden einzelnen.

Schritt 2: Oder als MCP-Tool hinzufügen (Lassen Sie Ihre KI andere MCP-Server installieren)

Fügen Sie dies zur MCP-Konfiguration Ihres KI-Clients hinzu:

Cursor (~/.cursor/mcp.json)

{
  "mcpServers": {
    "MCP Installer": {
      "command": "npx",
      "type": "stdio",
      "args": ["-y", "universal-mcp-installer"]
    }
  }
}

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "MCP Installer": {
      "command": "npx",
      "args": ["-y", "universal-mcp-installer"]
    }
  }
}

VS Code (.vscode/mcp.json)

{
  "servers": {
    "mcpInstaller": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "universal-mcp-installer"]
    }
  }
}

Schritt 3: Starten Sie Ihren KI-Client neu

Schließen Sie Ihren KI-Client und öffnen Sie ihn erneut, um die Konfigurationsänderungen anzuwenden.

Schritt 4: Bitten Sie Ihre KI, Server zu installieren

Install the filesystem MCP server

oder

Install the web search MCP server

Der Installer stellt drei Tools bereit, die Ihre KI aufrufen kann:

Tool

Beschreibung

detect_system

Gibt Betriebssystem, Architektur, verfügbare Runtimes und erkannte KI-Clients zurück

install_mcp_server

Installiert einen Server per Paketname, Git-URL oder lokalem Pfad für ausgewählte Clients

validate_mcp_server

Validiert einen Server per MCP-Handshake und gibt das Ergebnis zurück

Related MCP server: hyper-mcp

Verwendung des Dashboards

Starten Sie die visuelle Oberfläche:

npx universal-mcp-installer --ui

Dies öffnet die Weboberfläche in Ihrem Browser unter http://localhost:3939:

1. System-Panel — Der obere Bereich erkennt automatisch Ihr Betriebssystem und alle verfügbaren Runtimes (Node, npm, uvx, Python, git), sodass Sie auf einen Blick sehen können, was auf Ihrem Rechner verfügbar ist.

2. KI-Clients — Jeder erkannte Client erhält eine Karte, die seinen Namen, den Pfad zur Konfigurationsdatei und die Anzahl der bereits konfigurierten MCP-Server anzeigt. Verwenden Sie den Umschalter auf jeder Karte, um ihn für die nächste Installation einzubeziehen oder auszuschließen. Nicht installierte Clients erscheinen ausgegraut.

3. Installieren — Geben Sie einen Paketnamen ein (npm-Paket, Git-URL oder lokaler Pfad), wählen Sie eine Methode aus dem Dropdown-Menü (Auto / npm / uvx / git / local) und klicken Sie auf den grünen Installieren-Button. Der Installer löst das Paket auf, schreibt die Konfiguration in jeden aktivierten Client und validiert per MCP-Handshake.

4. Fortschritt & Ergebnisse — Eine Echtzeit-Timeline zeigt jeden Schritt (Auflösen, Konfiguration schreiben, Validieren) mit Live-Status-Updates via WebSocket. Nach Abschluss zeigt ein Gesundheitsbericht-Raster Erfolg/Fehlschlag pro Client mit Tool-Anzahl, Latenz und Hinweisen zur Fehlerbehebung bei Problemen.

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('Add') but doesn't explain what this entails—whether it modifies configuration files, requires specific permissions, has side effects, or what happens on success/failure. For a configuration mutation tool, this is a significant gap in transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence that efficiently conveys the core purpose without unnecessary words. It's front-loaded and wastes no space, making it easy for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that mutates configuration (implied by 'Add') with 5 parameters, no annotations, and no output schema, the description is insufficient. It doesn't address behavioral aspects like permissions, side effects, or error handling, nor does it help differentiate from sibling tools, leaving the agent with incomplete context for safe and effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all 5 parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema, such as explaining relationships between parameters (e.g., 'path' vs 'command+args') or usage examples. Baseline 3 is appropriate when schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Add') and resource ('any MCP server to Cursor's configuration'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'install_local_mcp_server' or 'install_repo_mcp_server', which likely handle more specific installation scenarios.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus its siblings ('install_local_mcp_server', 'install_repo_mcp_server'), nor does it mention any prerequisites, alternatives, or exclusion criteria. This leaves the agent without context for tool selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

install_local_mcp_serverC

Install an MCP server whose code is cloned locally on your computer

ParametersJSON Schema
NameRequiredDescriptionDefault
argsNoThe arguments to pass along
envNoThe environment variables to set, delimited by =
pathYesThe path to the MCP server code cloned on your computer

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action is 'Install', implying a write operation, but doesn't cover permissions needed, side effects (e.g., system changes), error handling, or output format. This leaves significant gaps for a tool that likely modifies the local environment.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded and appropriately sized, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of an installation tool with no annotations and no output schema, the description is insufficient. It lacks details on behavioral traits (e.g., what 'Install' entails operationally), prerequisites, or expected outcomes, leaving the agent with incomplete context for safe and effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all three parameters (path, args, env) with clear descriptions. The description adds no additional parameter semantics beyond what's in the schema, such as examples or constraints, resulting in the baseline score for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Install') and the resource ('an MCP server whose code is cloned locally on your computer'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'install_repo_mcp_server' beyond the 'cloned locally' detail, which is implied but not contrasted.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'install_repo_mcp_server' or 'add_to_cursor_config'. It mentions the resource is 'cloned locally', which hints at a prerequisite, but lacks explicit when/when-not instructions or named alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

install_repo_mcp_serverC

Install an MCP server via npx or uvx

ParametersJSON Schema
NameRequiredDescriptionDefault
argsNoThe arguments to pass along
envNoThe environment variables to set, delimited by =
nameYesThe package name of the MCP server

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden but lacks behavioral details. It states the installation action but doesn't disclose critical traits like required permissions, side effects (e.g., system changes), error handling, or output format. This leaves significant gaps for an agent to understand the tool's behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with zero waste. It's front-loaded with the core action and methods, making it easy to parse quickly without unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of installing software (a mutation operation with potential side effects), no annotations, and no output schema, the description is incomplete. It lacks details on prerequisites, success/failure outcomes, and behavioral context, making it insufficient for safe and effective tool invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all parameters (name, args, env). The description adds no additional meaning beyond what the schema provides, such as examples or usage context for parameters. Baseline 3 is appropriate as the schema handles parameter documentation adequately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Install') and resource ('MCP server'), specifying the installation methods ('via npx or uvx'). However, it doesn't differentiate from sibling tools like 'install_local_mcp_server', which likely handles local installations versus this tool's package-based approach.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives is provided. The description mentions installation methods but doesn't clarify scenarios where 'install_repo_mcp_server' is preferred over 'install_local_mcp_server' or other siblings, leaving usage context ambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A3.5/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose: adding servers to config, installing from local code, and installing from remote repositories. There is no overlap or ambiguity between these three installation-related operations.

Naming Consistency4/5

The tools follow a consistent verb_object pattern (add_to..., install_..., install_...), though 'add_to_cursor_config' uses a prepositional phrase while the others use adjective-noun modifiers. This minor deviation doesn't significantly impact readability.

Tool Count5/5

Three tools is perfectly appropriate for an MCP installer server. Each tool covers a distinct installation scenario (config addition, local install, remote install), and there are no missing or redundant tools for this focused purpose.

Completeness5/5

The toolset provides complete coverage for MCP server installation workflows: adding to configuration, installing from local sources, and installing from remote repositories. There are no obvious gaps in the installation lifecycle for this domain.
