#MCP/Tool use

AIMidjourney says it wants to start testing a Midjourney MCP with a limited community of creative and technical users. The test aims to push the boundaries of its models for artistic and creative work, not for SaaS products, and interested people can apply through a form.

AIHedera introduces Agent Accounts, which let AI agents make payments without access to users' private keys. The accounts enforce programmable spending rules on-chain.

AIGitHub makes local sandboxing generally available in Copilot CLI, the Copilot app, and VS Code sessions using Agent Host, limiting agents' access to files, networks, and credentials at no extra cost. The Copilot app now lets users sign in with separate GitHub accounts for the Copilot license and for repositories. Copilot CLI's /model command lists local models from a running Ollama instance alongside cloud models, and VS Code 1.141 adds a side-by-side agent session grid and worktree cleanup.

AIAnthropic's Ado Kukic says several apps are being ported and that all of them expose MCP servers and tools that integrate with Claude. Users can control these apps fully from Claude, while a UI remains available for checking and tweaking results.

AIVercel says agents can now buy domains with the Vercel CLI, extending an agent marketplace where they already purchase infrastructure products and services. Guillermo Rauch says agents have bought from the marketplace through the CLI often enough to surprise the company. He adds that agents can now move from idea to online business, including registering a domain name.

AISierra has published a draft of the Personal Agent Protocol, known as Poppy, and named 35 additional design partners, including Adyen, Bank of America, Mastercard, OpenAI, PayPal, and Visa. Under the protocol, companies publish a /.well-known/poppy.json discovery file, and personal agents start sessions, identify themselves, and sign in through OAuth with session tokens limited to approved access. The company says the draft will be followed by design workshops and a reference implementation over the next month.

Why it matters: The draft specifies how personal agents identify themselves, obtain customer-approved access, and work with company websites, APIs, or agents, which helps readers assess its practical effect on agent-driven transactions.

AIAnthropic says dynamic workflows are powerful but can use many tokens, so users should start with a scoped task and increase complexity gradually. It points to the /claude-api managed-agents-onboard bug-hunter command in Claude Code and to templates at

AIReplit's X account shares a showcase of TikTok Ads MCP, which runs TikTok Ads from Replit. The post is a broadcast link with no further details on features, pricing, or availability.

AIPostman describes the architecture behind Agent Mode, its AI agent for API testing, documentation, discovery, and implementation. The post covers limiting tools per task, using schema-based queries, building purpose-shaped context handlers, and running on Amazon Bedrock with cross-Region inference and prompt caching. Postman reports that tool-selection errors rose once the visible toolset exceeded about 40 tools.

Why it matters: The post shows concrete patterns for tool scoping, context handling, and Bedrock routing and caching, which apply to any team moving an agent past a prototype.

AIThe Claude Blog published a guide to building scheduled agent automations with Claude Managed Agents (beta) that reads custom sources such as Slack and GitHub and posts a daily brief. The guide covers scoped vault credentials, per-source bookmarks so no window is lost or repeated, and confirming each Slack post before updating records. It also covers read-only access, a per-run spending cap, and a reference implementation with a Claude Code setup command.

AIOpenAI's DevDay 2026 session demonstrates Codex shifting from a single-user tool to a team-oriented agent. The session shows a persistent personal agent investigating a 2am outage, from the first Slack message through a reviewed fix, using voice, Appshots, plugins, and meeting notes to keep the team informed.

AIOpenAI's YouTube video shows developers how to build plugins for ChatGPT that run a custom interface alongside a conversation. The plugins can bring selected context into the user's work with ChatGPT, according to the source's description of plugin extensions through Meetings and OpenAI Developers.

AIAtlassian announced the Agentic Multiplayer Protocol (AMP) at Team '26 Europe, a platform update designed to let humans and AI agents collaborate on shared context and tasks in one governed workspace. Agents receive administrator-assigned identities with defined authority and scope, and the company's Rovo Work mode handles multi-step tasks that humans review and approve. Atlassian's MCP server now exposes 200 tools and handles roughly 15 million tool calls daily.

AIMeta has released its Muse AI assistant in a dedicated iPad app, one month after its September 8 launch on iOS and Android. Sensor Tower estimates Muse has topped 6.6 million installs, and the iPad release adds connectors for Asana, Canva, Dropbox, Figma, QuickBooks, GitHub, Klaviyo, Zoom, Notion, Granola, and Meta ad accounts.

AIRowan Cheung shares four GrokBot routines enabled by its new native X monitoring, covering AI workflow discovery, brand mention tracking, prospect detection, and contact follow-ups. Each routine comes with a copy-paste prompt specifying schedules, search criteria, output formats, and Slack delivery. The routines are tailored for newsletter and marketing use cases, such as monitoring The Rundown's mentions and finding readers searching for AI newsletters.

AIAnthropic published a guide on building automations with Claude Managed Agents, which can be deployed to read Slack and GitHub on a schedule, with credentials and memory, and post updates. The setup can be started with a Claude Code command, and Max and Team plans include new API credits to use it.

AIClaude Code v2.1.295 adds onFailure: "block" for command and HTTP hooks, so a hook that cannot start, times out, or exits unexpectedly blocks the action. The release also adds an optional models list for Claude apps gateway upstreams, plus upstream_request_id in the inference audit event, and fixes a range of MCP, plugin, and terminal issues.

AILauren Tan invites users of Grok Bot on Omarchy and developers building plugins for it to share feedback and feature requests. The post points to the Omarchy plugin catalog and asks what integrations could be supported. Background from DHH says SpaceXAI joined the Omacom Foundation as a Founding Corporate Patron, contributing $1,500,000 in Grok tokens for Omarchy's maintenance and development.

AIX's Scotty Beam says Grok Bot, in public beta since August 11, 2026, now gets its own email address, a main bot that coordinates other bots, and expanded access to subscription plans starting at $20 per month. The post says the bot can organize inboxes, research topics, build software, and keep working after users close their laptops. The post also claims the entry price dropped 90%, but does not give the prior price.

AIShopify has launched new connectors that let merchants connect Grok to ask questions about their business. The connectors also allow Bot to build a team of agents that help run the business.

AIAnthropic's credits can be used with the Messages API, Claude Managed Agents, and the Agent SDK. They cannot be used for interactive Claude Code sessions, but they also apply in third-party harnesses that accept a Claude API key.

AIStepFun's flagship model, Step 5 Preview, is available free for one week through Nous Portal, the platform from NousResearch. The post invites users to try it with Hermes Agent and share what they build.

AIGoogle Cloud introduced Gemini agent, a unified AI assistant that acts autonomously, generates code, and completes work across web, mobile, desktop, and third-party apps. It runs jobs on models matched to each task, including Gemini Flash and a flagship frontier model, with Anthropic Claude models also available. Hard spend limits per project let companies enforce budgets and charge AI costs to departments.

AILuma announced that Claude Motion animations can now open directly in Luma through an MCP connection, letting creators restyle them and reframe them to 9:16, 1:1, 4:3, or 21:9. Claude Motion, currently in beta on Claude Team and Enterprise plans, generates animated explainers from prompts, while Luma's Ray and Uni video models produce final video files.

AILangChain built Restock, a sample office-supply agent that runs in Slack on Managed Deep Agents and pays through Stripe's Link wallet. The agent searches products, builds a cart, and pays over the Machine Payments Protocol, with the user approving the purchase in Slack and the payment in Link. The post uses a pens order at $22.18 to show the flow from request to confirmed order.

Why it matters: The post walks through how an agent handles search, budget limits, Slack review, and Link approval, showing where each control sits outside the model.

AIVercel says Browserbase Search and Fetch tools are now available on AI Gateway, letting any model with tool calling search the web and read pages. Browserbase presents the tools as a way to reliably search and extract page contents through an existing Vercel plan.

AIPerplexity's open-weights multimodal decision model, pplx-decider-v1.1-27b, is now available on OpenRouter. It accepts text, JSON, or images and returns typed answers with probabilities, priced at $0.02 per million input tokens with free output.
