Who's in your top 8? Today's vibe coding project is a Myspace-style Farcaster client proof of concept. Customizing the HTML and CSS *does* work: try it! It'd be fun in the future to circle back on this one and try adding Login with Farcaster and some Neynar endpoints for real content. https://v0-myspace-profile-interface.vercel.app

not yet. we found MCP is good if you want it to answer questions about farcaster but not if you want to write code using APIs. Then it still hallucinates, same as without MCP. That said, we are going to take another stab at it in a few weeks.

What can I do to help get it shipped before Farcon Builder day?

what's your use case? we could ship it now but it won't help writing code. That's an MCP level limitation afaik

yeah it still hallucinates API calls with MCP server alas we have LLM docs here: https://neynar.llmdocs.gopromptless.ai/ that you can feed in. Feedback on that is useful. Things we are doing in April before Farcon: - breaking up LLM docs into smaller chunks so free tier users can feed into LLMs - checking if MCP limitations still hold (I think they do) best way to help is to test and give us feedback when we share something

Can you elaborate on the writing code vs. answering questions. Nash MCP with a neynar api key in secrets gets to the right result within a few iterations. All the Nash mcp server is doing is executing code the llm writes. Which you can then get by asking llm for the code it used. Sonnet 3.7 under the hood

we were going for close to 100% success rate because we felt you can iterate without the MCP anyway

is doing something like this too heavy handed to get it to work? (my guess is Jordan will say yes, it should learn itself and create this info, not have a human write this translation layer) https://github.com/modelcontextprotocol/servers/tree/main/src/github

Are you saying something similar but for neynar? I’m not against one-off mcp servers, right now they make a lot of sense. I just think in the future great llms.txt and allowing arbitrary code execution is the ideal implementation for getting things done with ai.

Yes Like why wouldn’t Neynar have something like that github MCP?

That's a question for @rish :) Here's Nash one-shotting trending casts and then getting me the code it used: https://www.loom.com/share/c4003681f138443ba5bd732a330771c2

its not like it never happens, but if you try 10 different things, it wont work all 10 times. you're saying it works for you every time?

"write me code to deploy a token on clanker" fwiw if it works every time, would be eager to learn how and point users to your MCP server

This would need to use neynar to make a cast, right?

haha that would be acceptable and would good way to get around the actual api here's the api: https://docs.neynar.com/reference/deploy-fungible

Got it, was just wondering if I need to do more with my account and configuration. I'll give it a shot

and just to be fully clear - I am looking to get sold on this. That's why we spent time on this internally. What we found is that it will work after repeated trying but that also kinda works with llms.txt so the additional value was unclear. It's great for other things but the hallucination problems haven't gone away from what we could tell.
