Product analytics (and evals) for agent sessions on your MCP
Hi HN! We’re Theodore and Louis, founders of Armature (YC P26). We reconstruct the entire session behind the MCP tool calls you receive, including what the user asked their agent to do and what the agent thought. You wrap your MCP in 3 lines of code (our SDK is available in Typescript, Python and Go) and start seeing in your dashboard: - All sessions reconstructed: it’s like reading the real conversation the user had inside Claude or ChatGPT! - A ranking of your MCP most popular use cases, built from sessions clustering - The most frequent issues your users’ agents encounter so you can fix…

In plain words
Armature is an analytics platform for MCP (Model Context Protocol) tool integrations that reconstructs entire agent sessions including user requests and agent reasoning. Developers wrap their MCP in three lines of code using SDKs for Typescript, Python, or Go, then access a dashboard showing complete session transcripts, ranked use cases based on session clustering, and frequent issues users encounter. It's built for developers who want visibility into how their AI agents interact with their tools.

From the sources
Armature helps your product get picked by coding agents such as Claude Code, Codex and Cursor. Then it shows you what users do with your product through AI, and runs evals so it keeps working.
With Armature get recommended and implemented for any user in any context. Then see what users do, and run evals so it keeps working. A service we run with you: a dedicated growth engineer measures how agents choose tools in your category, and works with your team to get them to choose you. Armature Search® mimics how Claude Code and Codex search the web. It reaches over 90% similarity with their results in our tests, so we can evaluate every change before it ships. A self-serve product. Install it yourself, see what users do on your MCP, and keep it working with evals. One strong methodology, applied category by category across hundreds of runs: who gets picked, and in which context.…from armature.tech

Glue2025 · glue.ai · ▲291Glue is team chat optimized for AI. Today we're releasing support for MCP tools right in your Glue team conversations. Just like MCP in Cursor or Windsurf, you can now use any tool in a private AI chat or any Glue team thread while pulling in its full context to help. Using team chat context for MCP is kind of game-changing, letting you do anything from creating a calendar event or Linear issue to looking up data from an internal system. Our team has been using MCP tools as part of core team workflows for a few weeks now, and it's fantastic. We're particularly fans of remote-hosted MCP…
Mcp-Agent – Build effective agents with Model Context Protocol2025 · github.com · ▲80Hey 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…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
