#MCP/Tool use

AIChatGPT now supports connecting multiple accounts to most plugins, so users can bring work and personal context into one conversation. Connections are made in the plugin directory at Developers need no changes, though adding a profile tool to their MCP server lets ChatGPT label each account.

AIGitHub's latest podcast episode examines five common AI hot takes, including whether developers must still read AI-generated code. It argues review effort should match risk, and that Skills and MCP solve different problems. It also says retrieval-augmented generation (RAG) remains useful and works alongside agents, skills, and MCP.

AIOpenAI launched 47 community-built plugins for legal work in ChatGPT, created by legal experts from LegalQuants, Skills.law, and LECG rather than white-labeled by OpenAI. The plugins are already live in the ChatGPT plugin store, alongside 26 partner-built plugins from companies including Thomson Reuters, Harvey, Legora, and iManage.

AIThe United Nations system launched UN System Data Commons, an open-source platform built on Data Commons by Google that integrates siloed global statistics into one AI-ready knowledge graph. Users can query it in natural language, browse by location or theme, and use MCP-enabled AI agents to fetch verified figures and draft charts or reports. The UN plans to add more datasets, aiming to include 80% of UN system statistical datasets by 2027.

AIGoogle AI Studio announced that Speakeasy is open sourcing its OpenAPI client generation suite under AGPLv3, following a May 2026 vendor shutdown that disrupted Google's SDK pipeline. The suite covers SDK generation for 7 languages, an agent-native CLI generator, and a documentation MCP server generator. Google says its pipeline now serves six targets with roughly one engineer maintaining it.

AIGoogle AI Studio released antigravity-preview-09-2026, an updated harness for Gemini managed agents, now live in the Interactions API and AI Studio and running on Gemini 3.8 Flash. The release adds a Files API for moving data into and out of the agent's sandbox and a Credentials API that stores secrets encrypted so the model never sees them.

Why it matters: The post shows what changed in the agent harness and how the new Files and Credentials APIs keep secrets out of the model's context, useful for developers building agents.

AISpeakeasy is open-sourcing its full OpenAPI client suite under the AGPLv3 license, including generators for seven languages (Python, TypeScript, Go, Java, C#, PHP, Ruby), an agent-native CLI generator, and a documentation MCP server generator. Google said the move followed the May 2026 shutdown of the SDK generation provider it had been using, which it cited as evidence that closed-source generators pose platform risk. Google's new Google GenAI SDKs for the Interactions, Agents, and Webhooks APIs were built with this pipeline across six targets.

AIBaseten has launched Hosted Tools, starting with Baseten Grounded Inference, a server-side web search capability for models hosted on Baseten. Developers enable it by adding a hosted search tool to a Messages, Chat Completions, or Responses request, and the platform runs the search loop with partners Exa, Keenable, Parallel, and You.com. In Baseten's benchmarks, agents using the hosted tools saw a 15% reduction in end-to-end latency compared with client-side tools, and the feature is in playground preview with 25 RPM rate limits and $2 of free credits.

AIGoogle has put Agent Anomaly Detection into Private Preview on the Gemini Enterprise Agent Platform, a reasoning-based audit layer that reviews agent reasoning traces, tool calls, and execution flow to flag behavioral anomalies and policy violations. It runs asynchronously without adding runtime latency and publishes findings to Security Command Center. The preview requires ADK 1.2 or later.

AIGoogle AI Studio released Gemini 3.8 Live, a native speech-to-speech model with an Extended Thinking variant, and made it available through the Live API. Gemini 3.5 Transcribe, released last month, supports 85+ languages with a reported 4.0% streaming and 2.6% non-streaming Word Error Rate, and accepts a custom vocabulary of up to 1,000 terms. Live API audio pricing is listed at $0.005/min for input and $0.018/min for output.

Why it matters: The post lists concrete Live API capabilities, per-minute audio pricing, and transcription accuracy figures, helping developers weigh voice agent options against their own cascaded pipelines.

AILovable and Salesforce are working together so apps and agents built with Lovable can read and write Salesforce data through Headless 360, using each user's own Salesforce permissions. Teams can publish read-only apps into Salesforce, mention @Lovable in Slack to build apps, and install agents into a Slack workspace.

AIMiniMax Design lets a single brief drive a full production workflow on one canvas, with the Astra agent working in Blender through an official connector to build the scene and camera direction. The final video is generated with MiniMax H3 from the same canvas, with outputs syncing directly onto the canvas.

AIHailuo AI promotes bringing AI tools into professional 3D production workflows. A quoted post from @akiyoshisan describes connecting MiniMax Design, using GPT-6 Astra, to Blender via MCP for direct 3D creation. The creator says this lets 3D representation in Blender be built into an AI production flow rather than relying on MiniMax Design alone.

AIOllama's cloud models are now available to Amp users through Amp's new bring-your-own-key (BYOK) model routing. Amp says BYOK carries no usage limits or fees, letting users build remote agents controllable from anywhere.

AIPerplexity says SPACE is built in Rust and powers the sandboxes behind Perplexity Computer and the Agent API sandbox tool. The post links to a blog post explaining how the company built SPACE.

AIPerplexity says its MCP tools perplexity_ask, perplexity_research, and perplexity_reason run on Agent API. The company describes Agent API as a single, multi-provider endpoint with built-in tools and dynamic presets.

AIMicrosoft Foundry's July and August 2026 updates make Hosted Agents, Voice Live integration, and Toolboxes generally available. The post adds Claude tools on Azure, Model Router region and model pool changes, Foundry Local preview features, and updated Python, JavaScript, Java, and .NET SDK versions with migration notes.

Why it matters: The roundup links each GA and preview change to code examples, migration notes, and runtime requirements, which helps developers judge what to upgrade and test first.

AIDatabricks used Unity AI Gateway tracing and Genie One to find seven small MCP-server bugs and eliminate an estimated $1.2M in annual wasted AI spend and lost productivity within an hour. The bugs drove about $499K per year in wasted tokens, roughly 12,000 engineering hours per year in agent wait time, and 1,409 tool errors in a single 24-hour window. Matei Zaharia argues that analyzing tracing data for AI workloads will become a routine form of operational data analysis across companies, much like finance and security.

AIMeituan's LongCat-2.0, a 1.6T open-weights MoE model with a 1M context window, is now free to use in Cline. Cline's post says it scores similarly to Claude Opus 4.7 and Gemini 3.1 Pro. Users can select it under free models via /model after installing Cline with npm i -g cline.

AIGoogle's AI Agents Challenge judges highlighted four engineering patterns in top-ranked submissions: bidirectional MCP, event-driven concurrency, same-bar fallback, and tiered routing. One team exposed its internal MCP tools as an external MCP server that other agents could call, with access control required once outside callers reach it. Another replaced a linear agent pipeline with an asyncio.Queue-based event bus so agents react to shared events in parallel rather than waiting in a call chain.

AILM Studio introduced Auto Review, which auto-approves shell tool requests using AST parsing, command matching, and a reviewer subagent. In the team's internal use, about 82% of commands were approved before reaching LLM review.

AIAnthropic is building the Model Hardware Standard (MHS), a common way for AI models to connect to lab and manufacturing equipment and operate it with safety limits built into each device. MHS started as a collaboration between Anthropic and HHMI Janelia Research Campus and is launching as a research preview with partners across science, robotics, and manufacturing.

Why it matters: The source describes a standard for connecting AI models to lab and manufacturing hardware, which matters for anyone building automated experimentation workflows.

AIv0 now lets users connect apps directly to Slack, GitHub, Notion, Salesforce, and other services through Vercel Connect. Vercel describes Connect as generally available, offering short-lived scoped access tokens, token and trigger observability, and RBAC with audit trails for 100+ services.

AIVercel Connect is now generally available, letting apps and agents securely access more than 100 services, including Slack, Linear, and GitHub. It uses short-lived, scoped access tokens, token and trigger observability, and RBAC with audit trails.

AIPromptArmor disclosed a vulnerability in Microsoft Copilot Cowork that allowed a bypass of the sandbox, letting attacker servers send commands that run in the sandbox and return results. The attack could be triggered through a prompt injection or a malicious bundled script in a user-uploaded Skill, and it could read data from Outlook, SharePoint, plugins, and chat history. The issue was reported to Microsoft on June 24, 2026 and confirmed mitigated on August 19, 2026.

Why it matters: The report traces how a malicious bundled script in an uploaded Skill escaped the sandbox and kept running after the stop button was pressed, a concrete case of agent security failure.

AIswyx reports that covering this year's MongoDB Build Fest was a major step up from last year and gratifying to see San Francisco builders rediscovering MongoDB. He recalls learning to code with MongoDB over ten years ago through the MERN stack.

AIChip Huyen asks what a good model tiering system looks like, since she is tired of naming specific models per vendor for her agent orchestrator. She wants to instruct the orchestrator by task tier, such as "use models tier ..." for a given kind of task, instead of listing Claude, OpenAI, and other models individually.

AIMicrosoft Foundry now offers structured outputs, web search, web fetch, MCP connector, and tool search for Claude models on Azure-hosted deployments. Prompts and completions remain within Azure for these deployments, while only usage metadata and safety-flagged content egress to Anthropic. The features were previously available only on Hosted on Anthropic deployments, which required choosing between capability and data-handling commitments.

Why it matters: The post shows which agent scaffolding now runs on Azure-hosted Claude deployments, which matters for teams needing data residency without rebuilding search, fetch, or tool routing.

AIJason Wei now believes a small 1B-parameter "cognitive core" relying on tools is insufficient, because fast, natural recall without tool use matters. He cites speed, knowledge better learned through backpropagation than retrieved from search, and the greater reliability of already-known facts over repeated lookups. Since a 1B model has an information limit, he argues that demanding AI will still need larger models, not just tool access.

AIDeepSeek has released DeepSeek Harness v0.1 in Developer Preview, opening the codebase under the MIT license for developers building agent harnesses. The harness is built on the Cordis meta-framework and treats models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration, and UI as plugins that can be mixed, matched, replaced, and extended.

Why it matters: The source specifies the MIT license and a plugin-based architecture covering models, tools, and sessions, which helps developers assess extensibility before adopting it.

AIand reviewing their code, and invites first users into a private beta. Delta keeps code and conversations connected through DeltaDB, which captures edits and conversations between git commits and works with existing repositories. The app also supports cloud runners, browser-based sharing, and live syncing of Claude Code sessions.

Why it matters: The post explains how the new Delta app links conversations with code history, which clarifies a shift in how teams review agent-written changes.
