AgentKey

The tool discovery part is really interesting. As agents get access to more tools, managing context efficiently will become a huge challenge. How does AgentKey handle custom/private APIs?

It's useful. How does auto-failover decide which source to switch to when one goes down?

the interesting part isn't any single integration, it's that the agent gets a whole catalog. my research assistant went from "answers from training data" to "checked five live sources" with zero code from me.

For research workflows, having FRED + finnhub + yahoo finance next to social sentiment behind the same key is a sneaky-good combo. Macro context and market chatter in one loop.

Hey the token math on tool discovery is honestly the most concrete detail in the whole pitch. Going from roughly 35,000 tokens to about 1,500 by training a retrieval layer instead of dumping every endpoint definition into context is a real architecture decision, not just a marketing line, and it's the kind of problem that quietly breaks a lot of MCP integrations once they scale past a handful of tools for sure.But when the retrieval model picks the wrong endpoint for an ambiguous request, is that visible anywhere, or does a wrong pick just look like a silent bad result downstream?

Installing into Claude Code with one command is the right call — most MCP setups still die in config. Does failover switch sources silently, or does the agent get told the data came from a different provider?

Half my agent demos used to die live because one upstream API picked that moment to have an outage. Failover should be table stakes and somehow nobody else ships it.

honestly the auto failover part sounds super useful, would be great if there was a way to see which data source it switched to and why, like a quick log or notification. that way its easier to trust the results when something jumps from one provider to another.

Every cool MCP server I found wanted its own key from a service with its own signup and its own minimum spend. The unbundling was exhausting. Glad someone rebundled it.

Hi Product Hunt, I'm Mogu, founder of Chainbase. Today I'm really happy to share the newest project out of our lab: AgentKey. It's been in private beta for a while, and a few thousand people have been using it and helping us shape it along the way, so it finally feels ready to put in front of you here.

Here's the thing we kept coming back to. Agents have gotten genuinely good at doing tasks. What they don't have is eyes. They can reason and act, but they can't actually see the live internet, which is where almost all the useful tools and real-time data actually live. So you end up with a strange gap: an agent smart enough to do the work, sitting behind a window it can't look through.

And today, giving an agent those eyes is a chore. You wire up one API for search, another for scraping, another for social, another for market data. You babysit a pile of keys and bills, and you basically have to understand the plumbing before you can even start. Most people who'd benefit from this never get past that part.

So we built AgentKey. You install it like a plugin, and your agent gets access to a whole marketplace of capabilities behind a single account. No juggling APIs, no keys to manage, no need to be technical. One account, one bill, and your agent suddenly gets a lot more powerful.

Right now the marketplace is organized into a few tiers, and it keeps growing:

- Everyday tools: search, web scraping, social media
- Professional data: finance, crypto, business data
- Life and travel: weather, maps, trip planning, and more

It already plugs into 20+ of the agents people actually use, including Claude, Codex, Openclaw, WorkBuddy and Cursor. And because everything sits behind one marketplace, if a provider has a bad day your agent can fall back to another source and keep running.

We really believe agents are about to bloom into a huge, messy, wonderful ecosystem. What excites me most is that people can finally hand their agents the real, complicated work, not just the basic stuff, and actually trust it to get done. That's most of why we're launching here. It's free to start, no card needed. Please go try to break it and tell me what's missing. I'll be in the comments all day.
