"Node-RED" matching MCP servers:

Enables retrieval and analysis of graph data from the Pythagraph RED API. Provides detailed graph statistics, node/edge distributions, and formatted table outputs for data visualization and analysis.

MCP server providing tools to search Red Hat KCS solutions, retrieve solution details, search cases, and get case details via Red Hat APIs.

Enables natural language conversations with Spain's electrical grid data through Claude, providing real-time access to electricity demand, generation, prices, and emissions data from Red Eléctrica de España (REE).

Enables querying Red Hat security data including CSAF advisories, CVEs, and OVAL streams through natural language.

Local deterministic BM25 memory for AI agents — offline-first, no API key, SHA-256 content-addressed shards, stdio MCP transport. Same query always returns the same ranked result.

Integrates with Red Hat APIs to enable searching Knowledge Centered Support (KCS) solutions, retrieving solution details, searching support cases, and obtaining case details through LLM applications.

Provides access to Mina blockchain data, enabling queries for events, actions, and network state information through a standardized interface.

Enables AI models to manage a Drupal-shaped content store over MCP, including nodes, vocabularies, terms, tag filtering, and trigram/semantic search, while logging every tool call for observability.

Enables Claude Code to search, browse, and read its own past conversation history across all projects using BM25 keyword search.

Enables AI agents to search and retrieve FRED economic time series, including vintage (as-published) data, with tools for series search, observation retrieval, release calendar, revision history, and more.

An advanced integration package that leverages OpenRouter and Perplexity APIs to provide enhanced web search capabilities, offering both simple and complex query processing with file attachment support.

This MCP server allows Cursor AI users to search and retrieve SAP Notes and Knowledge Base articles using SAP Passport authentication and Playwright automation.

Provides a code search service via MCP, allowing AI clients to perform fast, indexed searches across large codebases using Zoekt, with support for filters like repository, language, and path.

Enables users to interrogate ChatGPT, Perplexity, and Gemini with buyer questions and live web search to learn whether a business is recommended, ranked, competing with others, and having its website cited. Returns structured findings and estimated provider costs.

Enables any MCP-compatible LLM to perform AI-powered web research using Google's AI Mode, returning synthesized and cited answers instead of raw search results.

A Model Context Protocol server for querying and reading articles from a how-to documentation portal, with search and retrieval tools scoped to the token's user permissions.

Provides read-only MCP tools for searching and asking over private documents via a local RAG service (reed), returning ranked passages with citations while keeping data on the machine.

Enables fast, low-token code search for AI coding agents via a local BM25 engine built on SQLite FTS5, with support for camelCase, snake_case, and Japanese text. Provides a stateless MCP stdio server and a Hermes adapter for multi-agent environments.

Enables AI-driven semantic code search using Windsurf's reverse-engineered SWE-grep protocol to query local codebases with natural language. It executes local search tools like ripgrep and tree-node-cli to return relevant file paths and line ranges to MCP-compatible clients.

Enables semantic search over codebases using natural language queries, returning relevant code snippets with source locations. Integrates with Claude Code for automatic codebase exploration.
