"Free and Easy-to-Use Minecraft Protocol Servers for Proof of Concept Projects" matching MCP servers:

Runtime access for AI coding agents to observe and control Android and iOS apps.

Enables LLMs to perform conceptual search over local PDF/EPUB documents using a RAG pipeline with corpus-driven concept extraction and WordNet enrichment.

Concept-test your product with synthetic consumers, straight from Claude Code. It turns free-text reactions from roleplayed personas into purchase-intent reports using Semantic Similarity Rating.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

Enables AI agents to operate a local containerized Paper/Folia Minecraft test server, including lifecycle control, version switching, world rebuilds, RCON, plugin management, config read/write, and optional MCC bot slots.

Enables developers to turn standard Python functions into Model Context Protocol tools for Claude Desktop and Claude Code using simple decorators, with automatic schema generation and a built-in config generator.

Enables clients to retrieve structured work briefings and item details, analyze blockers, and submit next-action proposals through streamable HTTP tools backed by Amazon Bedrock conversations. Supports human-confirmed approval or cancellation while preserving revisions, decision histories, and safe reuse or invalidation of pending proposals.

Launches multiple Browser-Use agents to automatically test websites for UI bugs, broken links, accessibility issues, and other technical problems on both live and localhost sites.

Enables managing GitHub Projects v2 boards through Claude Code and Codex, including project and item administration, field updates, sprint boards, epic rollups, and desired-state planning.

Enables access to a local Markdown knowledge base via MCP, currently only providing a ping tool.

Provides MCP tools to search, retrieve, and answer questions from the public Open Finance Brasil Confluence documentation using BM25-based local indexing.

An MCP server for intelligently reading Java source code, supporting extraction from Maven dependencies and local projects with dual decompilers.

Enables AI assistants to search, read, and cite Title 38 of the Code of Federal Regulations from a locally built SQLite full-text index, using read-only tools for ranked regulation search, full section retrieval, hierarchy browsing, part listing, and index freshness/health checks. All queries run offline against the local index, returning ranked hits with citations, snippets, cross-references, and staleness notices.

A local MCP server that lets AI assistants control a Minecraft player on a local Paper server, enabling movement, block breaking/placing, combat, inventory management, chat, and op-level commands like teleport, gamemode, and summoning.

Searches and queries the official minecraft wiki to answer any minecraft-related question with precision!

MCP server that provides six verification tools (Lean proof checking, axiom audit, bound, gridlock check, certificate verification, residency check) with honest status reporting (ok/failed/unavailable) to prevent agents from claiming unchecked proofs passed.

A Minecraft MCP Server powered by Mineflayer API. It allows to control a Minecraft character in real-time, allowing AI assistants to build structures, explore the world, and interact with the game environment through natural language instruction

Provides comprehensive administrator-level control for Minecraft Java Edition servers, allowing AI to manage world generation, server configuration, and player moderation. It enables remote execution of RCON commands, NBT data parsing, and automated backup management through the Model Context Protocol.

Enables MCP-connected assistants to read and edit Easy Spec Playwright project flows, scenarios, page objects, and variables, and to drive live browser automation through a human-approved browser extension side panel.

A Model Context Protocol server that automatically reads the Claude Desktop configuration file and presents all available MCP services in an easy-to-copy format at the top of the tools list.

Enables AI agents to read GitHub Projects v2 boards over stdio, letting them list projects and their items across repositories so cross-repository work can be coordinated without scanning every repository. The read-only MVP authenticates via a GitHub App installation token minted at runtime and exposes list_projects, get_project, and list_project_items tools with cursor-based pagination.

Enables local authoring and testing of Minecraft Java adventure maps through validated MCP tools, including structure building, snapshot/restore, and automated QA.

An MCP server that bridges ChatGPT Web Pro to local tools, enabling file read/write, shell command execution, git operations, and search within a specified project directory.

Allows AI models to observe and interact with the Minecraft world through a bot.

A set of MCP servers that allow AI assistants to control a Minecraft server and client, including running commands, managing plugins, taking screenshots, and calling arbitrary API methods via reflection.

Enables assistants and agents to query calendar availability from Google, Outlook, iCloud, or ICS feeds and return free time slots for specified days, date ranges, or pasted messages. It exposes read-only tools for finding availability and checking calendar readability without exposing calendar addresses.

Enables querying normalized real-world asset data through MCP tools, including listing assets, retrieving asset details, comparing yields against SOFR, and checking eligibility by jurisdiction.

Enables MCP clients to control a Minecraft survival character via Mineflayer, with a web UI, viewer, and custom TypeScript script execution.

Enables AI-driven creation and editing of Minecraft creature models, textures, and skeletal animations in Blockbench, targeting BetterModel and ModelEngine workflows.

Audits any MCP server (stdio or Streamable HTTP, legacy or modern era) with wire-level conformance, security, and behavior-regression checks, producing a fingerprinted delivery report and CI regression suite.
