The new Arcade Plugin takes you from signing up for Arcade.dev to your first tool call in one install. Add it to Claude Code, Cursor, VS Code, Codex, and more, then sign in and ask your agent for something real, with no gateway to set up. arcade.dev/blog/arcade-plugi…

This October, we’re sharing Agent Horror Stories, real moments when an AI agent struck terror into a user’s heart. First up: @ptdamiba told his agent to “kill the clusters” so he’d stop getting billed. The billing stopped, because the agent deleted every cluster. 🎃

“Even if you pretend that you don’t have agents running inside of your organization, you do.” @nbarbettini on the CyberBytes podcast with David Huish, from governing agents to how fast Arcade.dev has grown since his last startup. youtube.com/watch?v=g_G12EuW…

If you’re in San Jose for AGNTCon + MCPCon, join Arcade.dev and @mcpjams the night before, Oct. 21 from 4 to 7 PM, for lightning demos, drinks, and people building with agents and MCP. 21+, no badge needed. Request a spot: luma.com/c6w736u5

Arcade.dev released Tool Recommendation last week. Here’s the simplest way to explain it: agents searching a big tool catalog walk every aisle at Home Depot to find a hammer, and Tool Recommendation sends them straight to it. arcade.dev/blog/tool-recomme…

The Arcade.dev team is heading to AGNTCon + MCPCon in San Jose, 10/22 and 10/23. Catch our four sessions, including a live demo where an agent tries a wire transfer and gets held for approval. Save 25% with OUTREACH25: events.linuxfoundation.org/a… @AgenticAIFdn

Arcade.dev’s new Tool Recommendation gives agents your whole tool catalog for up to 37% less in token costs, with up to 91% fewer input tokens per session on every model we tested. Available now in Arcade Cloud: arcade.dev/blog/tool-recomme…

Thanks to @VentureBeat for the exclusive on Tool Recommendation’s launch. @carlfranzen nailed the problem it solves: “Connecting an agent to more business systems also makes its instructions larger and more expensive.” venturebeat.com/orchestratio…

Arcade.dev has three new teammates and a lot of confetti to clean up. Welcome to Thanh-Ha Nguyen (ex-Okta), Don Tregonning (ex-Splunk), and Alex Laughnan (ex-Asana), who all survived the confetti cannon. We’re hiring for the next round: arcade.dev/careers

If your afternoon in SF is open, there’s still time to join Arcade.dev, @mastra, and @elastic for a hands-on MCP for GTM workshop today at #SFTechWeek. Build a sales agent and see four ways a discount request goes wrong, plus how to catch them. Register: luma.com/q1jn2gjj

Our very own @kamathematic tried to announce Arcade.dev’s new Private Registry before Pascal finished making coffee. Open any Arcade MCP URL in your browser to see your tools, what you can access, and request anything missing, right from the page. arcade.dev/blog/private-regi…

Thanks to the banking, insurance, payments, retail, and healthcare leaders who joined Arcade.dev and @LangChain for dinner in Toronto. Determinism was the hot topic, since models can be probabilistic but the controls on what agents do need to be consistent.

Traders can't approve their own trades, and in a new @Forbes piece, Arcade.dev CEO @TheMostlyGreat argues AI agents shouldn't approve their own actions either. An agent on a shared service account can act with more access than any one employee would get. Read the full piece: forbes.com/councils/forbesbu…

Builders are already adopting MCP's July 28 spec. In Arcade.dev's ToolBench rescan of 90,000+ open-source servers, the 5.8% using its stateless request handling score about eight points higher on average. Full findings: arcade.dev/blog/toolbench-re…

Arcade.dev will be at #MCPDevSummit Toronto, presented by @AgenticAIFdn, on Oct. 5 and 6. Stop by our booth to talk identity, authorization, and auditability for MCP in production. Booth hours: Monday 10:20am to 6:30pm, Tuesday 10:20am to 3:40pm.

On 10/8 during #SFTechWeek, build a GTM agent with Arcade.dev, @mastra, and @elastic in a four-hour, hands-on MCP workshop. An AE's discount request goes wrong four ways, and Arcade's governance layer catches all four outside the model. Register: luma.com/q1jn2gjj

Arcade.dev's ToolBench now covers 90,000+ open-source MCP servers and over 600K agent-ready tools, making it the most comprehensive look at the MCP server and agent tool ecosystem out there. Across all of it, growth is far outpacing safety and quality, with only 260 servers earning an A and the riskiest tools getting the least documentation. arcade.dev/blog/toolbench-re…

Last night at HogPatch, @posthog's SF co-working space, @ptdamiba showed enterprise builders how to build a governed agent with Arcade at Fix My Agent. The big theme was how agents act on a user's behalf, and the MCP questions came from people who've clearly built with it. Thanks to all who joined.
