Project mention: I got tired of copy-pasting GitHub issues into AI chats. So I fixed it. | dev.to | 2026-04-10
What really inspired this was Context7. Watching it fetch fresh docs as a subagent made something click:

Project mention: CLI over MCP: a small Chrome DevTools experiment in Copilot CLI | dev.to | 2026-06-10
I ran the same browser smoke task through two paths: direct Chrome DevTools MCP and a custom CLI skill around mcp2cli. In GitHub Copilot CLI with gpt-5.3-codex-medium, direct Chrome DevTools MCP added about 5k tokens of upfront context before the agent did any work. The runtime table is too small and too noisy to rank the tools. The useful question is where the agent pays to discover the browser-control surface.

Project mention: The AI Harness: why your AI coding agent is only as smart as the repo you put it in | dev.to | 2026-05-01Hi. I am an engineer at Activepieces, an open source automation platform (think Zapier, but you can self host it and read the source code). I write TypeScript for a living. I argue with bots about tabs vs spaces now. And our team spent the last few months really, really invested in one question:

OpenMetadata
The Open Context Layer for Data and AI , OpenMetadata is the open platform for building trusted data context and business semantics for humans, AI assistants, and agents.
Project mention: Show HN: Marmot – Single-binary data catalog (no Kafka, no Elasticsearch) | news.ycombinator.com | 2025-12-02Great to see Marmot here and I'm a huge fan of your project. Recently, we deployed a catalog but we went with open-metadata https://open-metadata.org/ another amazing project.
What we missed on marmot was existing integrations with Airflow and other plugins like Tableau, PowerBI etc. We're an enterprise and needed a more mature product. Fingers crossed marmot reaches there soon.

mcp
Browser MCP is a Model Context Provider (MCP) server that allows AI applications to control your browser (by BrowserMCP)
Project mention: Ask HN: Has anyone replaced Claude/GPT with a local model for daily coding? | news.ycombinator.com | 2026-06-15Pi is decent.
I've used the cli agents for claude, cursor, and pi, plus several custom harnesses I've written myself from time to time as experiments (and I guess technically gastown, if we're calling that a harness).
Pi is... just fine.
It does what I need it to, has a decent selection of tooling out of the box, integrates nicely with other tools, and generally gets out of my way enough that I don't think about it much anymore.
If you can run ~30b models at decent speeds, I think most folks would be pleasantly surprised at how capable they are with pi.
Tack on some of the extensions (ex https://pi.dev/packages/pi-mcp-adapter?name=mcp and https://pi.dev/packages/pi-web-access?name=search) and I get web tooling (ex - perplexity search), access to mcps to do things like drive chrome (https://browsermcp.io/) or firefox (https://github.com/mozilla/firefox-devtools-mcp)
It's fine. Is it as good as a subsidized top tier model? Nope. Is it free and still very capable? Yup.
And personally, I've been having a LOT of fun with the pi sdk (https://pi.dev/docs/latest/sdk)
Which is something that all the other providers charge you api access rates for (ex - thousands a month).

Project mention: We've raised $10M to build open source AI security | news.ycombinator.com | 2026-06-02
Hey, Ildar here, CTO at Archestra
Archestra is an open-source AI gateway and MCP orchestrator. It runs MCP servers in sandboxed environments, applies deterministic context-aware policy at the tool-call level, and handles the auth, audit, cost tracking, and observability, so an in-house AI team can let business users connect to real internal data. Now we are raising next round to expand.
We’re strong believers that there should be an independent, battle-tested, cloud-native, open-source platform that's free from big players and takes care of all that boring stuff. Something like GitLab, Grafana, or Clickhouse.
Repo is here: https://github.com/archestra-ai/archestra Matvey (CEO), Joey (Co-founder), and I are all in the thread. Ask us anything, including the unflattering stuff.

contextplus
Semantic Intelligence for Large-Scale Engineering. Context+ is an MCP server designed for developers who demand 99% accuracy. By combining RAG, Tree-sitter AST, Spectral Clustering, and Obsidian-style linking, Context+ turns a massive codebase into a searchable, hierarchical feature graph.
Project mention: Show HN: I Built Context+ AST and Embeddings for Codebase Understanding | news.ycombinator.com | 2026-03-01I cant believe i just made a permanent solution to context bloat and open sourced it all!
when we tested this tool (Context+) for solving an issue on the OpenCode repository, the agent using this tool used ~6.5k fewer tokens, found the code and fixed it in half the time!
the results were surprising: 6 to 10k tokens saved per prompt, completed task in ~2 minutes while the agent running without the tool took ~4 mins for the same and got stuck in loops
built an entire beast by using all the modern tools that we could think of: undo trees, semantic search by meaning (by haskellforall), advanced refactoring, blast radius, advanced file context trees, restore points... i can keep going on
semantic code search and context trees are the future of agentic coding and this tool proves it
the feature i loved the most is semantic search and how it gets things done 2x faster with least possible tokens
it makes an agent that actually knows what it’s doing and not just guessing, it makes meaning from your code similar to RAG. if you aren't optimizing your context, you are just burning money
this tool is still under development, it can have unexpected behavior and the docs need updates but the video shows the reality of how fast it can be

ref-tools-mcp
Helping coding agents never make mistakes working with public or private libraries without wasting the context window.
Project mention: Ref uses MCP to build documentation search that minimizes token use | news.ycombinator.com | 2025-07-29Hi! I'm the developer of Ref (https://ref.tools), the MCP server for giving coding agents access to public and private docs. Ref's goal is to provide exactly the tokens you need to guide the model and nothing else.
I've been working on this one MCP server for about 6 months and I wanted to share the ways I've used and considered using different MCP features. If you're new to MCP, I hope this article can give you a sense of how developers can leverage MCP in practice.
Repo: https://github.com/ref-tools/ref-tools-mcp
And because I get asked this ALL the time : how is Ref different from Context7?
