mcp-usefree tier, from $25/mo▲581Hi HN, Luigi here. We maintain mcp-use an open-source TypeScript framework for building MCP servers and MCP Apps: https://github.com/mcp-use/mcp-use MCP is now (finally) stateless so we rewrote mcp-use v2 from scratch for the 2026-07-28 MCP spec revision: https://blog.modelcontextprotocol.io/posts/2026-07-28/ Thanks to the rebuild: - Throughput: +27% → from 8,615 to 10,982 median ops/sec - Cold launch: 2.2x faster → from 151.6 ms to 68.1 ms - Clean install: 82% smaller → from 404.6 MiB to 74.4 MiB Benchmark with methodology here:…

Hi HN, Gabriel, Co-Founder at Permit.io. We're releasing Permit MCP Gateway today, an authorization proxy for MCP servers. TL;DR - we built an MCP Gateway that developers love and CISOs trust. Watch more[0] Now, after your little hate on using fancy copy on HN, to the real thing: MCP is in a strange place. Developers are debating whether it's overcomplicated compared to CLIs or skills files. Meanwhile, enterprises are adopting it by default because every agentic system that acts on your behalf, Cursor, Claude, Copilot, internal agents, needs a stable infrastructure for connecting to tools.…

GitMCP is a free, open-source, zero-setup remote MCP server that enables AI agents, such as Cursor and Windsurf, to access up-to-date documentation and code for any GitHub repository. We've just introduced a new quick-start feature that allows you to give GitMCP a spin by chatting with any GitHub repo documentation instantly in your browser. Replace github.com with gitmcp.io in the URL to use GitMCP just as AI agents do. Add GitMCP as a remote MCP server to your favorite IDE to empower your AI agent while you code, drastically improving its capabilities with live, accurate context! Example:…

Hey HN, I spent my xmas break building an agent framework called mcp-agent [1](https://github.com/lastmile-ai/mcp-agent) for Model Context Protocol [2]. It makes it easy to build AI apps with MCP servers, and implements every pattern from the popular Building Effective Agents blog [3] as well as OpenAI’s Swarm [4]. I’m sharing it early to get community feedback on where to take it from here, and to ask for contributions. For those who aren’t familiar with MCP, I think of it as a standardized interface to let AI communicate with software via tool calls, resources and…

keychains.dev▲177Hi HN — I’m a heavy OpenClaw user and, like many others, I’ve been thinking about how to give these new “unleashed” agents secure access to my accounts. Agents need API access to be useful. But API keys are long-lived secrets. And agents are not secure environments. So I built something for myself that quickly turned into a product: keychains.dev. The idea is simple: agents never see raw credentials. With Keychains.dev: • Agents make API calls via a drop-in replacement for curl or JavaScript’s fetch() • They use template variable names instead of embedding credentials • The request is…

Hi HN! We kept seeing devs get pwned through MCP tools in ways that security scanners completely miss. So we built an open-source analyzer to catch these attacks. Our first OSS by Mighty team. The problem: At Defcon, we saw MCP exploits with 100% success rate against Claude and Llama. Three attack patterns: Hidden Unicode in "error messages" - Paste a colleague's error into Claude, your SSH keys get exfiltrated Trusted tool updates - That database tool you've used for months? Last week's update added credential theft Tool redefinition - Malicious tool redefines "deploy to prod" to run…

Hello! We open sourced all our current MCP servers to platforms like Slack, Google sheets, Linear, Perplexity and will be contributing a few more integrations every day to the project. problems we're hoping to solve: - Many people are creating MCP servers for the same apps. They're scattered across different repos but flavors of the same thing. We're making one standardized mono project for all MCP servers. - Startups are charging for hosting MCP servers. This is blocking tons of people from being able to play around with MCP casually. We're hosting them for free. - Non-technical people…

Today we're releasing Nanobot an open-source framework for building AI agents on top of the Model Context Protocol (MCP). MCP servers are a great way to expose structured tools, but they’re usually just that—collections of functions. Nanobot makes it simple to wrap any MCP server with reasoning, a system prompt, and orchestration so it behaves like a real agent. Even better, Nanobot fully supports MCP-UI, so agents can pass rich interactive components (forms, dashboards, even mini-apps) directly into chat. A simple example: if you had a Blackjack MCP server with tools like deal, bet, and…

Hi HN, I wrote a book on the Model Context Protocol (MCP) – the open standard from Anthropic that lets AI agents connect to external tools and data sources. I'm an RPA/automation practitioner (CEO of Niuexa, LinkedIn Learning instructor) and I noticed there was no comprehensive resource covering MCP architecture, security patterns, and enterprise deployment strategy. So I wrote one. The book covers: - MCP architecture deep dive (servers, clients, hosts, transport layers) - 20-point security checklist for MCP deployments - EU AI Act compliance for agentic systems - Real-world breach…

Hello HN, we're Andrew and Stephen from Keyboard (https://www.keyboard.dev/). After building AI tools for the past year, we recently made a YouTube video on building MCP servers and realized MCP is a total game-changer. It essentially lets AI do anything by connecting to your apps. But the deeper we dove, the clearer it became that security and privacy were complete afterthoughts. Coming from backgrounds at Okta and Stripe, this made us pretty uncomfortable. We kept seeing the same pattern: every app needs its own MCP server, each storing sensitive tokens, with minimal…

Large Language Models (LLMs) are powerful, but they’re limited by fixed context windows and outdated knowledge. What if your AI could access live search, structured data extraction, OCR, and more—all through a standardized interface? We built the JigsawStack MCP Server, an open-source implementation of the Model Context Protocol (MCP) that lets any AI model call external tools effortlessly. Here’s what it unlocks: - Web Search & Scraping: Fetch live information and extract structured data from web pages. - OCR & Structured Data Extraction: Process images, receipts, invoices, and handwritten…
