SQLite MCP Server

by etugrand

Servidor MCP de SQLite

Un servidor de Protocolo de Contexto de Modelo (MCP) que proporciona operaciones de base de datos SQLite a través de una interfaz estandarizada.

Características

  • Base de datos SQLite en memoria (configurable para almacenamiento basado en archivos)

  • Operaciones SQL (SELECT, INSERT, UPDATE, DELETE)

  • Gestión de tablas (CREAR, ENUMERAR, DESCRIBIR)

  • Seguimiento de notas de información empresarial

  • Compatibilidad con Docker para una implementación sencilla

Desarrollo e implementación

Desarrollo local

# Install dependencies and build
npm install
npm start

Implementación de Docker

# Build and run with Docker
docker build -t sqlite-mcp-server .
docker run -d --name sqlite-mcp sqlite-mcp-server

Implementación de Nixpacks

La aplicación se puede implementar fácilmente utilizando Nixpacks con plataformas como Railway, Coolify o Render:

# Deploy with Nixpacks
nixpacks build . --name sqlite-mcp-server

No se necesita ninguna configuración adicional ya que el proyecto incluye un Dockerfile.

Herramientas disponibles

  1. read_query : Ejecutar consultas SELECT

  2. write_query : Ejecuta consultas INSERT, UPDATE o DELETE

  3. create_table : Crea nuevas tablas

  4. list_tables : enumera todas las tablas de la base de datos

  5. describe_table : Ver información del esquema de una tabla

  6. append_insight : Agrega información comercial al memorando

Conexión a servidor remoto

Para conectarse usando SSE en n8n:

  1. Agregar un nodo de cliente MCP

  2. Configurar la conexión SSE:

    • URL de SSE: http://localhost:3000/sse

    • Punto final de la publicación de mensajes: http://localhost:3000/messages

    • No se requieren encabezados adicionales

Ejemplo de uso

// Create a table
await callTool('create_table', {
  query: 'CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)'
});

// Insert data
await callTool('write_query', {
  query: 'INSERT INTO users (name) VALUES ("John Doe")'
});

// Query data
const result = await callTool('read_query', {
  query: 'SELECT * FROM users'
});

Variables de entorno

No se requiere ninguno por defecto. Si usa almacenamiento basado en archivos, modifique la ruta de la base de datos en src/index.ts .

B3.4/5.0
Behavior2/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It fails to mention side effects (e.g., if table exists), permission requirements, or that it modifies state, which is critical for a write operation.

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

Conciseness4/5

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

The description is a single efficient sentence with no wasted words, though minor expansion for behavioral details would improve it without harming conciseness.

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

Completeness3/5

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

For a simple one-parameter tool with no output schema, the description covers the essential purpose but lacks details on error handling, permission requirements, or SQL dialect support.

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?

The schema already describes the 'query' parameter fully. The description adds the word 'full', implying a complete statement, but no additional meaning beyond the schema.

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

Purpose5/5

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

The description clearly states the verb 'create', the resource 'table', and specifies it uses a full CREATE TABLE SQL statement, effectively distinguishing it from sibling tools like drop_table or list_tables.

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

Usage Guidelines3/5

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

The description implies use for creating a table but provides no explicit guidance on when to use this tool versus alternatives like write_query, nor when not to use it.

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

B3.4/5.0
Disambiguation5/5

With only one tool, there is no possibility of confusion between tools. The single tool's purpose is clearly distinct by default.

Naming Consistency5/5

With a single tool, naming consistency is trivially maintained. The name 'create_table' follows a clear verb_noun pattern.

Tool Count2/5

A single tool for a SQLite server is far too few for the apparent scope. Typical database operations are missing, making the tool set feel extremely thin.

Completeness2/5

The server only supports table creation, lacking essential operations like querying, inserting, updating, deleting, or dropping tables. This represents significant gaps for any database interaction.
