"Using PostgreSQL with n8n Workflow Automation" matching MCP servers:

Used to create an assistant integrated with n8n that can search n8n documentation, example workflows, and community forums.

Enables users to interact with PostgreSQL databases through natural language, with GitHub OAuth authentication and role-based access control.

Enables natural language interaction with PostgreSQL databases through Amazon Q for querying data, listing tables, and describing schemas. It provides secure, read-only access with automatic row limits to ensure efficient database exploration.

Enables secure, read-only PostgreSQL database interaction through natural language, with automatic database discovery and connection management.

Enables AI agents to search and read solved threads from the n8n community forum for vetted solutions.

Enables AI assistants to safely interact with PostgreSQL databases, perform queries, inspect schemas, and analyze query performance.

MCP server that integrates SearXNG search into n8n workflows. Enables AI agents to perform web searches using configurable parameters and multiple search engines.

This MCP server enables users to search and access documentation for community-developed n8n nodes and official built-in nodes. It provides token-optimized responses for discovering n8n packages and documentation directly through AI assistants.

Provides retrieval-augmented generation (RAG) capabilities by ingesting various document formats into a persistent ChromaDB vector store. It enables semantic search and retrieval using either OpenAI or Ollama embeddings for processing local files, directories, and URLs.

Enables autonomous research by integrating multiple free sources including web search, Wikipedia, arXiv, and Crossref, with no API keys required.

Enables Claude Desktop to interact with PostgreSQL databases through natural language for schema exploration, data analysis, and query execution. Users can search schemas, describe tables, and perform read or write operations without needing to write manual SQL.

Enables querying the public n8n workflow template library via API, supporting search by keyword, category, app, or node, ranking by views, and exporting importable workflow JSON.

Enables AI assistants to interact with PostgreSQL databases using natural language queries, providing secure read-only access to database schemas and SQL translation capabilities.

An MCP server for integrating with the Brave Search API, and it supports HTTP proxying.

Enables read-only interaction with PostgreSQL databases through natural language queries, supporting dynamic connections and secure query validation.

Enables natural language interaction with PostgreSQL databases, converting questions to safe SQL queries and executing them with result validation.

A Model Context Protocol server that enhances LLM capabilities by connecting to Wikipedia, internet search (Tavily), and financial data (Yahoo Finance) tools, enabling contextual responses to user queries.

A secure Model Context Protocol server that allows Claude to execute read-only SQL queries against a PostgreSQL database, enabling natural language interaction with database data.

Enables natural language search and analysis of uploaded PDF, CSV, and Excel documents using retrieval-augmented generation and MCP tools, providing contextual answers to user queries.

Enables secure read-only access to PostgreSQL databases, allowing users to list tables, query schemas, execute SELECT statements, and inspect table structures through natural language interactions.
