BidSonar – MCP server for UK/EU government contracts and grants
Yo HN - I built BidSonar, a free index of UK & EU public-sector contracts and grants, which today I just shipped an MCP server for. The data is all public, scattered across a bunch of gov portals - I built the platform a couple years back as an aggregator. I've been using the MCP side to keep an eye on contract/grant opportunities for my services business and our clients which I'm finding (not surprisingly) more effective than navigating the traditional UI. Data's under OGL and the EU TED reuse notice; not affiliated with any procurement body - free to use, you just need an account. For…
What it does
Use BidSonar from Claude, Cursor, ChatGPT and more via MCP. Search UK & EU contracts, grants and organisations. OAuth-secured, read-only, revoke any time.
10 read-only tools over the same index the site runs on — every UK and EU contract, grant, buyer and supplier — answered in the assistant you already work in, with links back to the record. Opens BidSonar in Claude’s connector directory — turn it on there, signing in to Claude first if you need to. One endpoint, the same everywhere. Your client signs in to BidSonar the first time it connects. The Free plan allows one custom connector; Pro, Max, Team and Enterprise allow several. Run it in a terminal. Drop --scope user to add BidSonar to the current project only. claude mcp add --transport http bidsonar --scope user https://bidsonar.com/api/mcp Copy Cursor Settings → MCP → Add server, or…from bidsonar.com

- MAMCPfinder – An MCP server that finds and installs other MCP serversApr 2026 · mcpfinder.dev · ▲9
I’ve been building and using agents heavily lately. The Model Context Protocol ecosystem is growing insanely fast, but discovering and configuring new tools is still highly manual. Every time I needed to connect an agent to a new service, I had to browse registries, figure out the transport type, identify required env vars, and manually update "mcp.json" files. So I built MCPfinder. It aggregates servers from the official MCP registry, Glama, and Smithery (around 25,000 combined entries) into a deduplicated, ranked catalog. But the real twist is the DX: MCPfinder is itself an MCP server :D…
- UCUK Company Dashboard and Search (Lockdown Project)2020 · ▲8
Hi HN, https://companies.bx.tc My colleague and I put together this tool for easily searching UK company data. We run a few server side batches daily to extract data from various government sources before linking it all together in (what is now) a fairly large database. We're also using this project as a way to test out a new JS UI library we built (similar to Vue, but a bit faster) to see how it stands up in a real project. We'd love to hear your feedback and any ideas you have for how we can improve the dashboard! Thanks :)
- MSMCP server gives your agent a budget (save tokens, get smarter results)Apr 2026 · l6e.ai · ▲6
As a consultant I foot my own Cursor bills, and last month was $1,263. Opus is too good not to use, but there's no way to cap spending per session. After blowing through my Ultra limit, I realized how token-hungry Cursor + Opus really is. It spins up sub-agents, balloons the context window, and suddenly, a task I expected to cost $2 comes back at $8. My bill kept going up, but was I really going to switch to a worse model? No. So I built l6e: an MCP server that gives your agent the ability to budget. It works with Cursor, Claude Code, Windsurf, Openclaw, and every MCP-compatible application.…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

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…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
