StartenPublished by AI Build Infra • Official MCP Identifier: io.github.AI-BuildInfra/proof-graph
Traditional Retrieval-Augmented Generation (RAG) dumps 5,000 to 20,000 unverified tokens of noisy HTML, sidebars, and duplicate paragraphs into LLM prompts. This causes context bloat, higher token costs, latency spikes, and hallucination amplification.
ProofGraph replaces fuzzy text dumping with Minimum Sufficient Context backed by Cryptographic Provenance:
Question ──► Entity Resolution ──► Claim Verification ──► Evidence Ranking ──► Token Optimizer ──► Compact Proof Packet
🎯 ProofGraph retrieves proof, not just text.
npxNo installation required:
npx -y @aibuildinfra/proofgraph
npm install -g @aibuildinfra/proofgraph
Add ProofGraph to your MCP configuration file (claude_desktop_config.json or Antigravity/Cursor MCP settings):
{
"mcpServers": {
"proofgraph": {
"command": "npx",
"args": ["-y", "@aibuildinfra/proofgraph"]
}
}
}
ProofGraph equips AI agents with 12 powerful verification and retrieval tools:
┌────────────────────────────────────────────────────────────────────────────┐
│ PROOFGRAPH MCP TOOLS │
├─────────────────────────┬──────────────────────────────────────────────────┤
│ get_evidence_packet │ Primary retrieval: Minimal sufficient proof │
│ search_entities │ Multi-signal fuzzy & alias entity matching │
│ get_entity │ Canonical record, relationships & Schema.org │
│ verify_claim │ Verify assertions against cryptographic proof │

When an AI agent queries:
{
"question": "Is AI Build Infra associated with HumanCraft and ProofGraph?"
}
ProofGraph returns a compact, citation-grounded evidence packet:

FAQ
Kopieren Sie auf dieser Seite die stdio-Konfiguration für Cursor, Claude Desktop, Claude Code oder VS Code. Sie nutzt die Installation des Herausgebers, keinen PlugMCP-Proxy.
In diesem Eintrag ist keine erforderliche Umgebungsvariable aufgeführt.
ProofGraph (Antigravity MCP) läuft lokal über stdio.
