China Urges Banks to Curb Exposure to US Treasuries
Show HN: MCPlexor – MCP multiplexer that cuts agent context usage by 95%
I built MCPlexor to solve a token waste problem I kept running into with MCP-based agents.
The Problem: MCP (Model Context Protocol) is great for giving LLMs access to external tools. But if you connect multiple servers (GitHub, Linear, Postgres, Slack), you end up with 40-50k tokens of tool definitions injected into every request – before the agent even does anything.
On a 200k context model, that's 25% gone. On smaller models, it's worse. And most runs only use 1-2 tools.
The Solution: MCPlexor sits between your agent and your MCP servers. Instead of loading all tool definitions upfront:
Agent asks for a capability ("create an issue") MCPlexor routes to the right server using semantic matching Only relevant tools get exposed Result: ~500 tokens overhead instead of ~20k.
Technical Details: - Written in Go, single binary, no runtime deps - Supports both stdio and HTTP transports - Stores credentials in OS keychain (macOS Keychain, Windows Credential Manager, Linux keyring via zalando/go-keyring) - Works with Claude Desktop, Cursor, Augment Code, or any MCP-compatible client
The routing logic can run entirely locally using Ollama. No API calls, no cost, works offline.
Business Model (for transparency): - Local/Ollama users: completely free - Cloud tier (on waitlist): we run inference on efficient small models instead of Opus/Pro, pass on savings, take a margin The bet is that routing is a narrow enough task that a fine-tuned 7B model does it as well as a frontier model. Early testing suggests this works.
CLI uploads: https://github.com/arustagi101/mcplexor Install: `curl -fsSL https://mcplexor.com/install.sh | bash` Happy to answer questions about the architecture, the routing approach, or anything else.

Show HN: Logifai – Auto-capture dev logs for AI coding assistants
The idea is simple: pipe your command through logifai, and Claude Code can search your logs directly.
npm run dev 2>&1 | logifai Hit an error → just ask Claude "what went wrong?" It captures everything into structured NDJSON, has a Web UI with live streaming, auto-redacts secrets, and includes a Claude Code Skill so Claude can search your logs without you ever copy-pasting terminal output.
It also has a Log Reference feature — select lines in the Web UI, click "Copy Ref", paste a compact logifai:// URI into Claude instead of hundreds of log lines. Keeps your context window clean.
It solves what I found to be the biggest pain point: the manual copy-paste shuttle between terminal and Claude Code.
Feedback and contributions welcome!
