MCP 2026-07-28 drops initialize, session IDs, and SSE resume; Sampling, Roots, and Logging are deprecated. I wrote minimal servers for both specs and diffed them with curl.
Tested MinishLab/semble on a 1595-md Astro blog: warm bm25 returns symbol definitions in 0.84s, hybrid mode loses `seasonalBanner` to the article corpus.
What to patch, rotate, and grep after OpenClaw 2026.4.22. Walks CVE-2026-44112/44113/44115/44118 as one chain on agent runtime, with detection log fields and 24h/1w response steps.
158K lines of AI-generated C# for a Cities: Skylines II total conversion mod. CivicRAG for codebase indexing, 300+ custom Roslyn analyzers as compile-time design rules, and manual visual debugging for render bugs AI couldn't see.
Vektor Memory v1.5.4 supersession chains positioned against YourMemory decay, Cloudflare key-overwrite, and CTX, with a BM25 vs cosine threshold trap and a 5-field minimum schema for agent memory.
Tested connecting MCP servers to Ollama local LLMs on M1 Max 64GB. MCPHost is deprecated, tool calling breaks with quantized models, and context fills fast. Includes working TypeScript and Python custom MCP server setups.
Starting from Claude Code's 1.67B token runaway (anthropics/claude-code#4095), this traces why tool responses need is_complete, retryable: false, duplicate detection, and orchestrator-level budget caps. Directly applicable to MCP server design.
Designing field-level confidence thresholds for human-in-the-loop document extraction, and the OCR and threshold walls hit when automating journal entries with freee MCP.
Playwright MCP v0.0.71 added browser_drop. MCP clients can now invoke Locator.drop directly, reducing the need to fake drag-and-drop via evaluate or mouse.move chains. Covers intermediate event firing and screenshot verification of CSS changes during drag.
A comparison of AI CMS features across Cosmic, Sanity, and Hygraph, examining agent execution, MCP connectivity, and editorial workflows. Hygraph's coverage in the original comparison article is corrected with official documentation.
