Java-based MCP server implementation that provides secure database operations for IBM Informix databases through a configurable architecture supporting both read-only and full SQL operations. Built with production-ready features including comprehensive logging, Docker containerization, connection pooling, and a modular configuration system that supports environment variable overrides and property files. The server implements standard MCP tools for SQL querying and schema introspection, with built-in security measures like SQL injection detection and configurable readonly modes, making it suitable for enterprise environments where controlled database access is needed for AI assistants and automated workflows.

This MCP server integrates with Google Maps to locate and evaluate medical facilities in emergency situations. Developed by AMOCA Corp., it provides tools for searching medical facilities, calculating routes, and checking availability within a 10km radius. The server implements sequential thinking for medical evaluation, enabling step-by-step clinical reasoning for more accurate facility matching based on patient symptoms and medical history. It's designed for use cases requiring urgent healthcare decision-making and real-time medical facility information retrieval.

This AppleScript MCP framework, developed by Josh Rutkowski, enables seamless integration of AppleScript capabilities with the Model Context Protocol. It leverages TypeScript and the MCP SDK to provide a robust interface for interacting with macOS applications and system functions through natural language. The implementation is designed for developers looking to incorporate AI-driven automation and control of macOS environments, making it particularly useful for creating intelligent assistants, workflow automation tools, or AI-enhanced macOS applications. Its focus on AppleScript integration sets it apart by offering unique access to macOS-specific functionality within the MCP ecosystem.

Enables querying and interacting with 1C:Enterprise databases via COM connection without modifying the database.

Connects to Blacksmith CI to provide tools for listing and inspecting workflow runs, jobs, and logs. Includes test analytics capabilities such as detecting flaky tests, comparing test failures between runs, tracking test history, and analyzing failure patterns. Also provides usage and billing tools for monitoring core usage, cache statistics, and invoice amounts. Authenticates via session cookie with automatic extraction from Chrome.

MCP server for strings: text analyzer (word count/reading level), transformer (extract emails/URLs, mask data), diff, template engine, slug generator Install: npx @rog0x/mcp-string-tools

MCP server for pi that provides free web search, web fetch, advanced search, and scholarly paper search via hosted Exa and Parallel services without requiring an API key.

Enables searching for jobs with filtering by keywords, excluded keywords, remote preference, and time range.

Interfaces with the npm registry to search packages by keyword, retrieve detailed package information including version history and dependencies, compare two packages side by side, and view download statistics. Provides six tools covering package search, info lookup, download counts, version listing, package comparison, and dependency inspection. Requires no API keys or configuration.

Photon MCP — OSM geocoder

This MCP server provides an interface to the Chinese Railway (12306) system, allowing Claude to query train schedules, ticket availability, and related information. Built with Node.js and the Model Context Protocol SDK, it leverages the moment.js library for date handling and zod for input validation. The implementation exposes railway data through a structured API that can be integrated into conversations, making it useful for travel planning, itinerary creation, and transportation logistics within China without requiring users to navigate the official railway website.

Enables AI assistants to look up any Pine Script function, search TradingView documentation, and find code examples in real time.

Gmail MCP server — send, read, and search email. By Strider Labs.

StackExchange MCP — wraps the StackExchange API v2.3 (free, no auth required for read)

MCP server that bridges MQTT sensor data to MCP, allowing clients to query cached sensor readings and send commands via tools like list_topics, read_topic, and publish.

Enables AI assistants to query DalPraLab's SEO/GEO consulting services, prices, case studies, availability, and submit audit requests directly from MCP clients.

A starter template for building MCP servers that can integrate with Claude, Cursor, or other MCP-compatible AI assistants to create custom tools, resource providers, and prompt templates.

Validates every agent action against policy files before execution, implementing runtime governance enforcement. Supports path permissions (writable, read-only, forbidden), role-based boundaries, content pattern scanning for sensitive data, and quality gate validation. Achieves zero token overhead by loading governance files into server memory rather than including them in the agent context window. Provides three operational modes: Universal (role selection), Construction (full access), and Fixed (pre-assigned role).

Provides AI assistants with access to sales data from a Northwind-style database through GraphQL queries, enabling natural language requests for orders, customers, products, and analytics.

Provides AI agents with direct access to local Yomitan dictionary databases for offline Japanese vocabulary lookups, kanji searches, and sentence tokenization. It leverages the Yomitan browser extension's API to enable rich dictionary interactions and Anki flashcard field generation.
