What is Gapup MCP?

A hosted Model Context Protocol server exposing 100+ business expertise tools for AI agents. Each tool returns a structured, audited, board-ready JSON deliverable in 1-30 seconds.

Pay-per-call via x402 (USDC + EURC on Base + Optimism). No subscription, no API gateway. The price is encoded in the response — agents pay what they consume.

Why agents use it

• Board-ready output — Zod-typed JSON, persona-stricte, no chat fluff
• Dual-audience format — audience param routes human (Mistral gold-standard, ~30s) vs agent (Cerebras qwen-3-235b, <5s)
• Source-grounded — citations, DOIs, evidence trails; no hallucinated facts
• EU-first moats — DVF Cerema + Géorisques for real estate, OFAC + EU + UK + UN + SECO + SEMA + DFAT for sanctions
• Free tier real — 100 calls/mo without credit card, no rate-limit games

The contents of THIS repository (manifests, docs, SDK examples, governance files) are licensed under MIT — you can fork, translate, reuse the snippets, contribute back.

The hosted API at mcp.gapup.io is governed separately by the Gapup Terms of Service. The MIT grant does NOT cover commercial API usage at scale — that's a per-call x402 settlement.

The server implementation itself is private (closed-source). This repository contains zero server source code — only the public surface (manifests + docs + examples) that lets clients integrate with the hosted endpoint.
