A short case study from my "building and testing MCP agents" series — it stands on its own, but the method behind it is laid out in https://dev.to/langensjonathan/the-parameters-that-actually-matter-when-youre-tuning-an-ai-agent-2agd . TL;DR: I benchmarked two agents that are identical except for one thing — how many MCP servers they're connected to — on the exact same question. Both got the right answer, both called the same single tool. The one with more MCP servers attached still cost 28% more per question , purely from the extra tool schemas the model has to be told about on every single call, whether it uses them or not. The setup MAVERIK is my open-source MCP test bench: define a suite of questions with pass criteria, run it against one or more agent configurations, and compare the results on hard numbers. This post is one deliberately tiny experiment with it: change exactly one thing about an agent, hold everything else fixed, and see what the numbers attribute to that one change. I have a small "GitHub summarizer" agent: one system prompt, one job — answer questions about my GitHub account by calling the GitHub MCP server . I duplicated its configuration (MAVERIK supports this directly — same model, same prompt, same everything) and changed one field on the copy: the set of attached MCP servers, adding deepwiki , microsoft-learn , and context7 . Neither agent needs any of those three for the question I was about to ask; they were attached because that's what the "kitchen sink" version of this agent had accumulated over a few sessions of general-purpose use. Then I wrote the simplest possible test suite — one question: "How many repositories do I have?" with a contains criterion checking the answer includes the correct count. No judge model, no subjectivity — it either says the right number or it doesn't. I ran both agents against it, 2 repetitions each, same model ( claude-haiku ) for both, and pulled up MAVERIK's Agent Comparison report. Agent A — github on

I built a small Flask example that turns voicemail into a routing workflow. Code: https://github.com/team-telnyx/telnyx-code-examples/tree/main/voicemail-smart-router-python The app accepts either: a voicemail transcript an uploaded voicemail audio file For audio, it transcribes the voicemail first. Then it uses Telnyx AI Inference to classify the message and decide where it should go. Categories The app classifies voicemails into: urgent billing support sales spam routine Each category maps to a route: urgent -> Slack alert billing -> email support -> ticket queue sales -> CRM lead spam -> blocklist + archive routine -> daily digest Run it git clone https://github.com/team-telnyx/telnyx-code-examples.git cd telnyx-code-examples/voicemail-smart-router-python cp .env.example .env pip install -r requirements.txt python app.py Configure .env : TELNYX_API_KEY=your_telnyx_api_key AI_MODEL=zai-org/GLM-5.2 FALLBACK_MODEL=meta-llama/Llama-3.3-70B-Instruct HOST=127.0.0.1 Optional Slack webhook for urgent messages: SLACK_WEBHOOK=https://hooks.slack.com/... Classify a transcript curl -X POST http://localhost:5000/voicemails/transcript \ -H "Content-Type: application/json" \ -d '{ "transcript": "This is an emergency. Our production system is down and we need help immediately.", "caller_number": "+17177247292" }' Example response: { "category" : "urgent" , "confidence" : 1.0 , "priority" : "high" , "reason" : "The caller reports a production system outage requiring immediate attention." , "suggested_action" : "Escalate immediately to the on-call engineering team." , "route" : "slack" , "routed_to" : "#oncall-alerts" , "routing_status" : "delivered" } Process voicemail audio curl -X POST http://localhost:5000/voicemails/process \ -F "file=@voicemail.wav" \ -F "caller_number=+17177247292" For audio, the app calls: POST /v2/ai/audio/transcriptions using: distil-whisper/distil-large-v2 Then it calls: POST /v2/ai/chat/completions to classify the transcript. Routes included POST /voic

Buying multiple lamps for different rooms can get expensive. Govee’s rechargeable Table Lamp Classic gives you one lamp you can use throughout your home instead of getting one for every room, and right now it’s down to $59 ($21 off) at Amazon. That’s just $4 shy of the all-time low set during Prime Day, and […]

The latest discovery from NASA's Curiosity Mars rover is a field of honeycomb-shaped polygons covering a Martian valley called Valle Grande. As Gizmodo reports, Curiosity has snapped pictures of the unusual terrain texture before, called polygonal fractures, each about 1.5 to 3 inches wide, but NASA says it's previously only found them in small patches, […]

As of this week in Montana, any biotech company with an experimental drug has a clear path to selling it to consumers.
