Hello from Raviole Labs

Why we're building MCP servers, what we ship, and what we don't.

intromcp

We build MCP servers. Not a framework, not a platform, not a “suite.” Three small, sharp tools that hand an AI agent something it can’t do out of the box.

The thesis

Tool-use capable models (Claude, GPT-4, Gemini, local models with function calling) are stuck on the same problem: their context is small, their training data is stale, and they have no native way to do things. MCP is the cleanest answer to that we’ve seen, because it isolates the capability layer from the model layer. You give an agent a tool. Any compatible client picks it up. The model doesn’t change. The tool stays small.

So we picked three capabilities we wanted ourselves and built one MCP per capability.

What we ship

PredMCP is live. Twenty-four tools that pull from Polymarket, Hyperliquid perps, and HIP-4, plus the cross-venue signal tools that compare them. If you’ve ever wanted to ask your agent “what do markets think about BTC right now, and where do they disagree,” that’s the question PredMCP answers. Free tier (100 calls/day), Pro at $9/month with a 7-day trial. The MCP core is open source on GitHub.

The cleanest demo is one read:

HL perps:  BTC $79,740 | funding +0.0000125 | OI 31,100 BTC   (slightly bullish)
HIP-4:     BTC > $81,041 by 6am  →  YES 12%                  (very bearish)
Signal:    DIVERGENCE, perps slightly bullish, prediction market very bearish

One call, two venues compared. Hard to do by hand, easy to do here.

RoverMCP is in private alpha. It hands the agent a real browser with your real sessions. Other tools give you twelve commands and a clean fingerprint. Rover gives you forty-six tools with fallbacks, designed for agents that need to finish a job: log into a DeFi frontend, fill the form, capture the confirmation. Built by OpenClaw inside our ecosystem.

EngramMCP is live in v0.4.2. A local semantic memory layer for any MCP-compatible agent. Twenty-one tools (remember, recall, recent, watch, ingest, relate, and the rest). Sources: Notion, Drive, YouTube, Obsidian, voice notes, agent conversations, all indexed on your machine via SQLite and LanceDB with Ollama embeddings. We’re not shipping a note-taking app. Obsidian already does that better. We’re shipping the memory layer underneath, the part that talks to agents directly. Core is MIT on GitHub. Pro ($9/month) adds mobile capture and end-to-end encrypted multi-PC sync. Install: brew install raviolelabs/tap/engram.

What we don’t ship

We’re going to be honest about scope on every page of this site. A few things we will never promise:

  • Features we haven’t built.
  • Dates we can’t hit.
  • Cross-venue arbitrage where the venues don’t actually overlap.
  • Open-source repos for products that aren’t open-source.

If you read something on this site that sounds like marketing, we screwed up. Tell us.
