@apify @coinbase Cool! Love it

[Apify @apify]

Until today, agents could buy about 2,000 tools through x402.

We just 10x'd that to 20,000+ 🚀

In partnership with @coinbase, we’re launching x402 support to give autonomous agents access to the largest marketplace of web automation tools.

No account, API keys, or human in the loop.

Live-demoed at "The Trust Layer" @okta SF last night: an agent pays via @trySkyfire , runs an @apify Actor, pulls live prices from Amazon, Best Buy & eBay. Agents with wallets, working. Thanks @trySkyfire, love this partnership.

MCP connectors are live! Actors now work where you do🔌

Actors were once limited to the open web.

With connectors, they now securely connect to apps like @NotionHQ, @SlackHQ, @GitHub, or any MCP server, access business data, send results, and integrate with external workflows.

@jancurn @dsp_ I think the SEP-2549: TTL for List Results explains it.

"Two fields will be added ttlMs and cacheScope. The TTL tells clients how long the response may be considered fresh before re-fetching"

"TTL supplements rather than replaces the existing notif mechanism, both can coexist"

Dear @MCP_Community: after 3 weeks of late nights, 300 commits, and $300 spent on Claude Code, I’m excited to present:

𝚖𝚌𝚙𝚌 — a universal CLI client for MCP

It supports OAuth, sessions, --𝚓𝚜𝚘𝚗 for code mode, --𝚙𝚛𝚘𝚡𝚢 for sandboxes, and more

@apify Wow, let's go 😎

AI is here, but the tools are still missing. That’s your opportunity.

AI agents need web data extractors, automation workflows, MCP servers, and API wrappers.

Build them. Publish on Apify. $1M Challenge prize pool.

Good summary of the AI infra stack @anyscalecompute : Kubernetes + Ray + PyTorch + vLLM (with real-world examples)

[Jiří Spilka @jirkaspilka]

Greg Kamradt explained the ARC dataset—great breakdown of tough AI challenges

[Jiří Spilka @jirkaspilka]

RL post-training really works—heard from several people (and at Fully Connected)

[Jiří Spilka @jirkaspilka]

Spent the day at #ArizeObserve2025 🚦 Checking out observability for Apify MCP server: https://t.co/j4f7r8H5oM. Well-run event, solid talks, strong crowd. AI is moving fast! 🚀

[Jiří Spilka @jirkaspilka]

@Letta_AI : OS for LLMs = stateful agents with long-term memory (weeks, months, years)

[Jiří Spilka @jirkaspilka]

@VibeMarketer_ Thank you for using Apify and Apify's MCP server!

[Jiří Spilka @jirkaspilka]

Spending time in SF = event overload, but Fully Connected Conf by @wandb really stands out. Great vibe, super motivated crowd, 🔥 AI keynotes were inspiring. Users now expect frontier tech—“it works” isn’t enough. Awesome event!

#fullyconnected2025

Thanks to @traceloopdev for the best swag! 😍

Still wrapping my head around the AI Engineer World’s Fair 🤯 and the next conference is just around the corner! Here are my favorite takeaways from Day 2 at AI Engineer: 🧵👇

[Jiří Spilka @jirkaspilka]

René Brandel (Casco, YC X25): On AI agent security and common pitfalls—like exposing resource IDs, executing malicious code, and leaking secrets via third-party services. Most agents still run in full YOLO mode! 🦾⚠️
