Servidor MCP
Este paquete incluye un servidor MCP que expone la funcionalidad de extracción de líneas como una herramienta que puede ser utilizada por cualquier cliente MCP como Claude Desktop, VS Code u otras aplicaciones compatibles con MCP.
Herramientas disponibles
extract-lines : extrae un rango específico de líneas del contenido del texto
Instalación
Clonar el repositorio
Instalar dependencias:
npm installUso
Iniciar el servidor MCP
npm startEsto iniciará el servidor MCP utilizando el transporte stdio, al cual pueden conectarse los clientes MCP.
Conectarse al servidor

Nombre: Copiar y pegar
Comando:
node /path/to/copy-paste-mcp/dist/index.jsTransporte: stdio
Uso de la herramienta
Una vez conectado, podrá utilizar la herramienta a través de la interfaz de su cliente MCP:
Extraer líneas
Tool: extract-lines
Parameters:
- text: "Your multi-line text content goes here\nSecond line\nThird line"
- start_line: 1
- end_line: 2Esto devolverá las dos primeras líneas del contenido de texto proporcionado.
Ejemplos
Extraiga las líneas 10 a 20 de un bloque de texto grande:
Tool: extract-lines
Parameters:
- text: [your text content with many lines]
- start_line: 10

Tool: extract-lines
Parameters:
- text: [your text content]

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 mentions the extraction action but doesn't describe what happens with invalid inputs (e.g., start_line > end_line), whether the operation is read-only or has side effects, error handling, or output format. This leaves significant behavioral gaps for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's appropriately sized for this simple tool and front-loads the core functionality clearly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple text processing tool with no annotations, no output schema, and 100% schema coverage, the description is minimally adequate. It covers the basic purpose but lacks behavioral details and usage context that would help an agent use it correctly in practice.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, with all three parameters well-documented in the schema. The description adds no additional parameter semantics beyond implying a range operation. This meets the baseline of 3 when the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with a specific verb ('extract') and resource ('lines from text content'), and specifies the scope ('a specific range'). It doesn't need sibling differentiation since there are no sibling tools. However, it could be slightly more specific about what 'extract' means operationally.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
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, prerequisites, or constraints. It simply states what the tool does without context about appropriate use cases or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
With only one tool, there is no possibility of confusion or overlap with other tools, making disambiguation perfect.
The single tool uses a clear verb_noun pattern (extract-lines), and with no other tools to compare, consistency is inherently perfect.
One tool is too few for a server named 'Copy-Paste MCP', which suggests broader copy-paste functionality, making the scope feel incomplete and thin.
The tool only extracts lines from text, lacking obvious operations like copying full text, pasting, or handling other copy-paste tasks, indicating significant gaps for the domain.
