Packages

Free and premium REST API for real-time and historical stock prices, forex rates, cryptocurrency data, and technical indicators, widely used for financial analysis and trading applications.

MCP server that enables AI assistants to search, download, and analyze academic papers from arXiv, with local caching and specialized research analysis prompts.

astro-airflow-mcp is a Model Context Protocol (MCP) server (FastMCP-based) that exposes Apache Airflow functionality (via Airflow’s REST API) to AI agents. It can run standalone over MCP (stdio/HTTP) or as an Airflow 3.x plugin, and supports multiple Airflow auth styles (bearer token, basic auth, and username/password with OAuth2 token exchange for Airflow 3.x).

ComfyUI-AnimaTool provides tool interfaces (MCP server, ComfyUI-compatible HTTP routes, and an optional FastAPI server/CLI) that let an AI agent generate Anima anime/illustration images via a running ComfyUI instance. It supports structured prompts, aspect ratio presets, history/reroll, and batch generation (repeat and batch_size), and includes optional LoRA injection behavior.

drf-mcp-docs exposes Django REST Framework API documentation to AI coding agents via the Model Context Protocol (MCP). It provides MCP resources and tools to browse endpoints/schemas/auth methods and to generate frontend/client integration code snippets, using DRF schema generators (drf-spectacular, drf-yasg, or DRF built-in).

Provides an MCP (Model Context Protocol) server (Python) that integrates with Notion’s API to let MCP clients list/query databases, create/update pages, search a Notion workspace, and fetch database details and block children.

opencode-mcp is an MCP server that bridges MCP clients (via stdio) to the OpenCode headless API over HTTP. It auto-starts an OpenCode server when needed and exposes 79 tools, 10 resources, and 6 prompts for delegating coding, debugging, and project/session operations.

OpenTabs turns browser tabs (and existing authenticated browser sessions) into an agent-accessible tool system. It exposes actions via MCP tools, and supports a plugin system that discovers/registers site APIs for in-browser calls, plus built-in browser tools (e.g., screenshots/clicking/typing/network capture).

A Java-based Model Context Protocol (MCP) server that runs performance/load/benchmark tests against a target client (“Discovery Intech” by default), collects metrics (response time, token/cost estimates, dataset size, success/errors), and can export and monitor results. It supports MCP over STDIO, HTTP/SSE endpoints, and streamable HTTP mode.

railway-mcp is an unofficial community MCP (Model Context Protocol) server that lets MCP clients manage Railway.app infrastructure—projects, environments, services, deployments, variables, networks, and (partially) databases—via MCP tools using a Railway API token for authentication.

Provides an MCP server for Claude Code that persists “infinite memory” across sessions by saving conversation chunks and extracting/saving reusable “insights”. It auto-snapshots before Claude Code’s /compact and supports search (regex, BM25, optional semantic embeddings), retention/archiving, and multi-project organization.

Provides an MCP (Model Context Protocol) server that wraps Slither static analysis to analyze Solidity projects and expose contract/function metadata and Slither detector results via MCP tools. Includes caching of Slither project facts and an optional typed Python client for tool invocation.

Provides an MCP server (stdio transport) that uses xlwings to automate Microsoft Excel through session-based operations (open workbook sessions, read/write cell data, apply formulas, manage worksheets/ranges/tables, and create charts), with configurable session TTL and limits.

Zen is a self-hosted, single-binary notes app that stores markdown notes in SQLite with tag-based organization, BM25 full-text search, and an optional MCP server for AI agent integration with note operations.

Developer-focused email sending API with powerful routing, parsing, and validation features for transactional email delivery.

BrowserStack's official MCP server that enables agents to programmatically manage and execute test cases, run manual/automated tests on real devices and browsers, debug test failures, and perform accessibility testing through natural language prompts integrated into IDEs like VSCode, Cursor, and Claude Desktop.

An MCP (Model Context Protocol) server that performs multi-step web research using Tavily Search and Tavily Crawl, then returns structured JSON (including documentation instructions) for an LLM to generate detailed markdown documents. Optionally supports secure file writing of research outputs when explicitly enabled.

@ijonis/geo-lint is a Node.js/TypeScript CLI and programmatic linter for SEO + GEO (Generative Engine Optimization). It scans Markdown/MDX (and supports custom adapters for other content sources), reports structured violations as JSON (including file/field/line plus suggestion/fixStrategy), and can be used by AI agents to iteratively fix violations until the output is clean.

GoPeak is an MCP server for Godot Engine that exposes a large toolset (scene/project editing, runtime inspection, screenshots/input injection, and LSP/DAP-style debugging) to AI clients via the Model Context Protocol. It supports tool exposure profiles (compact/full/legacy), dynamic tool groups, and cursor-based pagination for tool listings.

n8n is a fair-code workflow automation platform with native AI capabilities, enabling technical teams to build automations using a visual editor combined with custom JavaScript/Python code across 400+ integrations, including LangChain-based AI agent workflows.
