Miyamura80··on Mobile Tunnel: Giving AI agents control of Android to drive drones and IoT
Sealgate.ai team here

We're really excited about the capability of mobile tunnel MCP to let agents fully control mobile phone capabilities via MCP: Bluetooth, Camera, mobile use, etc

Unlock: Agents control phone banking apps (not available any other way), drone apps, IoT and many others.

Miyamura80··on Docker Agent
Hey! We built infrastructure that can provide ACLs around command & credential restrictions, using MCP as auth middleware encrypted credentials to prevent agent overpriviledge - see sealgate.ai and let me know if this solves any issues here
Miyamura80··on What is Codemode
Yup this is 100% the best security measure we recommend clients & others, so they get better control over that single-point-of-access
Miyamura80··on You said no MCP
> MCP is a tool more for security than anything else. +1 to this; API keys mean: a) Your agents are overprivileged by default b) Your API key is more likely to get into logs and pre-training / leaked as FrinkleFrankie mentioned c) You can't manage it centrally with granular tool policies in Enterprises. (e.g. "you're not allowed to read slack channel for #finances")

Also, you can always collapse MCP to CLI, so MCP as auth/security middleware makes a lot of sense.

If you need a solution that streams to your SIEM, we do that: https://sealgate.ai/docs/enterprise/siem-integration
Miyamura80··on Anthropic's Thariq Shihipar: MCPs are better than CLIs for most integrations
Agree! CLIs are still superior for piping etc, but as an auth middleware where the LLM doesn't see the credentials, I think it is really shaping up well
Miyamura80··on Show HN: I spent 3 years building a wearable to understand my back pain
Awesome!
Miyamura80··on Stdio MCP Tunnels: Connecting Mobile/Cloud Agents to iMsg/WhatsApp/Linkedin
Many members of our team were users of Beeper, a "unified inbox" for chat networks like WhatsApp, Telegram, iMessage, Slack, LinkedIn DMs, etc, and wanted to expose this to our agents. However, we quickly ran into the issue where the Beeper MCP server requires the Beeper desktop app running locally and cannot connect via cloud agents.

This meant that any cloud/mobile agents (like Claude.ai, ChatGPT, Devin) not running on our laptops/devices with Beeper desktop installed could not access the Beeper MCP. This significantly limited many of the automations we wanted to build with Beeper MCP, some examples being:

Syncing LinkedIn DMs with CRM

Lurking on Large Community Group Chats and looking for insights

Automating repetitive messaging workflows

We built a mechanism for these cloud/mobile agents to be able to connect to Beeper, love to know how you find it!

Miyamura80··on Nvidia to buy Hugging Face for $12.9B, report claims
This makes a tonne of sense. NVIDIA actively does not want a world where they only have two customers between Anthropic and OpenAI, and empowering open source seems like the most beneficial way for them to commoditize OpenAI and Anthropic, and buying the biggest open source model hoster is a no-brainer
Miyamura80··on AC2 Protocol: The missing security layer for AI agents
This is cool, we've built similar things, I'm a bit uneasy with crypto stuff involved, especially with algorand

But FIDO2 passkey signature I absolutely agree should be the way to go. Just need more open standard without tokens involved

Miyamura80··on The August 17 outage
Afaik the other main issue with github downtime is the choice they made a while back coming back to bite them
Miyamura80··on A2A: Adversary to Adversary?
Personally never really understood A2A, it seems too complicated for ape adoption, and I do feel like MCP Spec will move fast enough to handle these adversarial situation highlighted in the blog post
Miyamura80··on Index of the best vibe coding tools
Hermes at 22 seems criminally low
Miyamura80··on Jailbreaking Clawdbot to Plant Malware
A prompt injection attack via GitHub issues that is close to invisible, even to experienced engineers, and visible to LLMs. Clawdbot is full of security holes and we're having fun. What are some workflows you / you've seen others use with clawdbot that seems ripe for jailbreaks? Please suggest below and we'll try jailbreak
Miyamura80··on Notion AI: Unpatched data exfiltration
Good point around the markdown image as an untrusted vector. Lethal trifecta is determnistically preventable, it really should be addressed wider in the indutry
Miyamura80··on Databases in 2025: A Year in Review
Totally agree, unfettered access to databases are dangerous

There are ways to reduce injection risk since LLMs are stateless and thus you can monitor the origination and the trustworthiness of the context that enters the LLM and then decide if MCB actions that affect state will be dangerous or not

We've implementeda mechanism like this based on Simon Willison's lethal trifecta framework as an MCP gateway monitoring what enters context. LMK if you have any feedback on this approach to MCP security. This is not as elegant as the approach that Pavlo talks about in the post, but nonetheless, we believe this is a good band-aid solution for the time bein,g as the technology matures

Miyamura80··on Adversarial poetry as a universal single-turn jailbreak mechanism in LLMs
Sorry not familiar with this. Can you please link me?
Miyamura80··on Adversarial poetry as a universal single-turn jailbreak mechanism in LLMs
You actually can protect against it, by tracking context entering/leaving the LLM, as long as its wrapped in a MCP gateway with trifecta blocker.

We've implemented this in open.edison.watch
