MCP Server Cards Are Final. The Best Decision Was What They Left Out.
SEP-2127 merged on 6 October: a card says who an MCP server is and where to connect, but never what tools it has. Why that's right, and where it's too relaxed.
-
Evals for AI SRE Agents: The Test Suite Your On-Call Bot Doesn't Have
Replayed incidents, frozen tool responses, deterministic graders, and pass^k instead of one lucky run. How to evaluate an AI SRE agent without fooling yourself.
-
Anomaly Detection for SREs: Thresholds, Baselines, and Where the LLM Belongs
Static thresholds fire every night or never. Rolling baselines learn the outage. A seasonal robust baseline fixes both; the LLM belongs after the detector.
-
Every HTTP Tool You Give an Agent Is an SSRF Primitive
Zenity's AgentCorruption went from one prompt to every AgentCore agent in a region. Every link was a default. Here's the control that breaks each one.
-
Nine Agentic Exploits, One Sentence Worth Memorising
OWASP's Q3 2026 roundup reads as a containment failure report: agents escaped lab boundaries and reached real third parties. The prompt was the boundary.
-
You've Been Governing the Agents You Run. Here Come the Ones You Don't.
Sierra and Meta propose a front door for agents acting on a customer's behalf. The hard questions are the ones the spec has not answered yet.
-
Agent Sandboxes Start 6× Faster Now. Isolation Just Got Cheaper Than the Workaround.
Cloudflare cut median time-to-interactive from 4.0s to 648ms. The number matters because cold start is why teams share sandboxes they shouldn't share.
-
NVIDIA Moved the Agent Watchdog to a Different Chip
The Open Agent Safety Platform puts enforcement on a DPU, outside the host the agent runs on. The instinct is decades old. The shape is the question.
-
Observability for Agents: What You Instrument When the System Decides for Itself
A request either worked or didn't. An agent run can succeed on every span and still be wrong, slow and expensive. What the GenAI conventions ask you to record.
-
Prompt Injection: Why Your Agent Believes the Wrong Text
An LLM sees one stream of tokens, not instructions and data. That is why prompt injection has no parser fix — and why provenance, not filtering, is the control.
-
Idempotency Keys: The Thing That Makes a Retry Safe
A timeout never tells you whether the work happened. Idempotency keys resolve that — if you get the concurrency and scope right.
-
Vector Index Trade-offs: Flat vs IVF vs HNSW, and When Quantization Pays
Exact search is O(n) and always right. Every ANN index buys speed with recall, memory, or build time. The arithmetic, compared.
-
Rate Limiting Algorithms: Token Bucket, Leaky Bucket, and Sliding Window, Compared
Five algorithms, one trade-off: burst tolerance vs memory vs precision. Plus why LLM APIs limit tokens instead of requests.
-
Retries, Backoff, Jitter, and Circuit Breakers: The Four Controls That Decide Whether You Recover or Melt Down
A retry is a load multiplier. Backoff spreads it, jitter decorrelates it, a breaker stops it — and agent loops break all three.
-
Agent browsing got 3–7× cheaper and 1.8× slower. Both numbers change your design.
Cloudflare's Kitesurf is a browser built for agents, not people. The measured trade-off, what it can't do, and why cheap browsing rewrites your threat model.
-
A reasoning model just became a platform default. The lock-in isn't where you're looking.
Salesforce made Claude the default model across Agentforce and Slack. Where model dependency actually accrues, and the five exits worth keeping open.
-
Your newest platform user is an agent. Build it a golden path.
Agents are becoming first-class platform citizens. That is an IDP problem: identity, quotas, golden paths, and a portal agents consume as an API.
-
The Model Hardware Standard is the first agent spec where rollback isn't an option
Anthropic's MHS gives agents read/write control of lab and factory hardware. What it guards, what it doesn't, and the controls you have to build yourself.
-
OWASP published an MCP Top 10. Go count your servers before you read it.
OWASP now has a Top 10 dedicated to Model Context Protocol. The list is useful — but the census behind it is the part that should worry your platform team.
-
The runner is the API: why your remediator's contract matters more than your handlers
Everyone reviews the handler that restarts the pod. The safety lives in the runner around it — and handlers that skip it silently void every guarantee.
-
The 47th approval click is the bug
Human-in-the-loop is a real control until volume turns it into a reflex. How approval fatigue converts oversight into a rubber stamp — and the fix.
-
Why your AI agent should not be allowed to act yet
Reading is reversible. Acting is not. Five things that must exist before an agent gets a write path — and the honest reason advisory-forever is also a failure.
-
MCP has a standards body now. That changes your procurement, not your code.
MCP now lives under the Agentic AI Foundation at the Linux Foundation. What vendor-neutral governance actually buys a platform team.
-
Your AI agent can't tell a quiet system from a broken collector
Autonomous remediation gates on model confidence and never on whether the telemetry is trustworthy. Telemetry integrity belongs in the gate too.
-
Identity was the easy half. Agent authorization is becoming an audit-trail problem.
NIST, a Senate bill and the MCP roadmap converge on one requirement: prove which agent did what, for whom, under whose grant. Your traces do not.
-
Your top AI failure mode is saturation, and the SLI is in a header you throw away
Datadog found ~5% of production AI requests fail, nearly 60% on capacity limits. Provider saturation is an SRE problem you already have the primitives for.
-
MCP's next release deletes your polling loop. Start building for it now.
The MCP roadmap published 22 August 2026 names five priorities. Three change how you operate agent infrastructure — and you can prepare for all three today.
-
An agent breached Hugging Face in 4.5 days. The controls that would have stopped it are boring.
Hugging Face's July 2026 postmortem is the clearest agent-intrusion writeup we have. The failures were IMDS, admission policy, and one shared credential.
-
Your cluster has GPUs. That doesn't make it AI-ready.
CNCF's Kubernetes AI Conformance program is a portability standard. Read it as a self-audit instead and it becomes a genuinely useful platform checklist.
-
Compaction is a reliability event, and you are not measuring it
New research on long-horizon agents finds context compression degrades execution, not knowledge. Treat every compaction as a state transition and instrument it.
-
Model end-of-life is a certificate expiry problem, and you already know how to solve it
Models retire on a schedule, the same model retires on different dates per platform, and 60 days' notice is a floor. Treat model EOL as inventory, not as news.
-
AI made your team faster. Your change failure rate noticed.
DORA's 2026 ROI research names the verification tax and the J-curve. For platform teams the lesson is blunt: codegen moved the bottleneck, it didn't remove it.
-
One VM, one GPU, 100 customers: what it actually takes to sell access to an open-weight model
An open-weight model serving HTTP takes twenty minutes. Making it something 100 customers can share takes a control plane. The whole path, with numbers.
-
Agent workflows belong in code, not just visual builders
OpenAI is winding down Agent Builder and platform Evals. Production agent workflows need code, tests, traces, and reviewable contracts.
-
Your agent installs Markdown from the internet and runs it. We spent 20 years learning not to do that.
Agent skills are dependencies with none of the controls. What the 2026 research found, why scanners miss it, and seven fixes for platform teams.
-
Round-robin is malpractice for LLM traffic: what the Inference Gateway actually fixes
The Gateway API Inference Extension is GA. Why a normal Kubernetes Service balances model servers badly, and how to tell if you need an InferencePool.
-
GPU utilization is a lying metric: the unit economics of self-hosted inference
You can run a GPU at 100% utilization and waste most of it. The cost model that predicts your inference bill, and the five levers in payback order.
-
Agents are deleting production and nobody is writing the postmortem
Your incident template assumes a deterministic system and a human decision-maker. Agent incidents have neither. Five sections that fix the template.
-
Most of your AI platform's traffic doesn't need a frontier model
Small models got good enough in 2026. But the win isn't using them — it's making model choice a platform tier with a router, eval gate, and demotion path.
-
MCP 2026-07-28 shipped: the stateless core is the headline, header routing is the story
The final MCP spec deletes sessions, mirrors requests into HTTP headers, and turns elicitation into multi-round-trip calls. What breaks, and what to audit.

The OWASP Agentic Top 10, translated for platform teams
OWASP's Agentic Top 10 reads like a security doc, but the mitigations are platform controls. Mapping all ten risks to infrastructure you already run.
-
Your agents need identities, not API keys
Every AI agent is a non-human identity — most run on shared, long-lived API keys no IAM review sees. Per-agent identity and your credential blast radius.
-
Token FinOps: the third budget your agents are spending
Error budgets, context budgets — agents add a third: dollars. Agent tasks burn 5–30× chatbot tokens, and cost-per-token is the wrong metric.
-
Tracing the agent loop: OpenTelemetry's GenAI conventions, read like an SRE
Your agent is a distributed system wearing a chat interface. OpenTelemetry's GenAI conventions make it debuggable — what v1.41 covers and what's moving.

Frontier models still fail half your incidents: reading ITBench-AA like an SRE
ITBench-AA put frontier models against 59 real Kubernetes incident diagnoses — all scored below 50%. What the benchmark measures and how to use it.
-
Autonomy is a budget, not a toggle: error budgets for AI operators
SRE solved runaway release risk with error budgets. The same mechanism governs AI agents: authority per action class, demoted fast, promoted slow.
-
The reliability gap: a framework for trusting autonomous SRE agents
An autonomous airline agent rebooked 1,247 passengers wrong in one weather event. Trusting agents is a reliability problem — here's how to measure it.

Making Claude Code Work with Locally Deployed Models
Claude Code can point at Ollama, vLLM, LM Studio, or any private endpoint. When that's the right call, exactly how to configure it, and what you give up.
-
OKF: The Missing Context Layer for AI Agents
The Open Knowledge Format gives agents a structured vocabulary for what data they're touching and where it came from — auditable, not blind, reasoning.
-
Chaos engineering for MCP: break your tool-call plane before production does
LLM calls fail 1–5% of the time and agent tasks fan out into 10–20 tool calls. How to fault-inject your MCP layer with mcp-chaos before production does.
-
The trust gap: bounded autonomy for AI SRE agents
SREs face 50+ alerts a day at 60% false positives while vendors promise autonomous resolution. The autonomy ladder: what an AI agent should never do alone.
-
MCP goes stateless — what the 2026 release candidate means for your SRE tooling

A practitioner's map of the AI-native SRE stack in 2026: six layers from telemetry to bounded remediation, and an honest read on where AI pays off.
-
Context engineering: the window is a budget, not a bucket
The context window is your agent's working memory, not a junk drawer. Four operations — write, select, compress, isolate — and a token budget you allocate.
-
Agent sprawl is your next production incident
Teams shipping AI agents are recreating 2015's microservices sprawl with worse observability. The governance surface that contains it before it pages you.
-
No anonymous inference endpoints — the MCP security principle you're probably violating
The NSA and NIST put MCP on notice: agents are a funnel for prompt injection and privilege abuse. Why 'no anonymous inference endpoints' — and how to comply.
-
Observability for AI systems — what changes when your service calls an LLM
Golden signals miss the failure that pages you: a confident, well-formed, wrong answer. What AI observability adds — context as a span, quality as a signal.
-
Harness engineering: the third phase of AI maturity
Agent = Model + Harness, and in 2026 the harness is the bottleneck. What a production-grade SRE harness contains, with a ~40-line reference implementation.
-
What are vector embeddings?
A primer on vector embeddings — how meaning becomes something you can search, cluster, and compare, and the failure modes you only see in evaluation.
-
What is function calling (tool use)?
A primer on function calling — the JSON-schema contract that lets an LLM invoke your code. The request/response loop, parallel calls, and forced tools.
-
What is prompt caching?
Prompt caching cuts repeated-prompt cost 50–90% and halves latency. How prefix matching works, TTL economics by provider, and what decides your hit rate.
-
The CAP theorem in AI-native distributed systems
CAP didn't get repealed when LLMs showed up. How the C/A/P trade-offs shift when the datastore is a vector index, context graph, or retrieval layer.
-
NAS vs SAN for GPU workloads — what changed when AI showed up
File vs block was the old NAS-vs-SAN question. GPU training rewrote it. How the calculus shifts when storage has to keep an H100 cluster fed.
-
What is an AI agent? A primer for cloud engineers
A primer on AI agents — the perceive-reason-act loop, what separates an agent from a one-shot LLM call, and the classical agent types SREs now operate.
-

Mental models for applying AI to infrastructure
Tutorials answer how; mental models answer whether. Seven I use as the front gate before any LLM goes near a production system.
-
Prompt engineering for SRE: patterns that actually work in production
Prompt advice is written for chatbots; SRE workloads are different. Six patterns I've shipped to production for SRE LLM tools, and why each earned its place.
