Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Remote Plugin
No local installation needed. Your AI client connects to the remote endpoint directly.
Add this to your MCP configuration to connect:

Structured data from PDFs and web pages, where every value is backed by an exact source quote — or honestly left null. Never guessed. Each result ships with a cryptographically signed receipt you can verify yourself.
proofetch is a hosted MCP server and HTTP API built for developers and AI agents. You pay only for fields that pass the proof — €0.02 per verified field. Empty or unprovable fields cost nothing.
https://proofetch-vektoris-ai-workflows.vercel.app/mcpio.github.Vektoris-AI/proofetchThis repository is the public connector & documentation for the hosted proofetch service. The extraction pipeline itself is operated as a service — you don't self-host it, you call it with an API key.
Normal extraction fills every field — even when the value is invented. You then have to re-check every number by hand. proofetch is different:
null + flagged, instead of a fabricated value.verdict: PASS).Buy prepaid balance (from €5) on the landing page — you get your key instantly after payment:

proofetch speaks the Model Context Protocol over Streamable HTTP. Point any MCP-capable client at the remote endpoint with your key as a bearer token.
Endpoint: https://proofetch-vektoris-ai-workflows.vercel.app/mcp
Auth: Authorization: Bearer YOUR_API_KEY
Tool: verified_extract — same contract as the HTTP API above.
Example client config (generic MCP streamable-http remote):
{
"mcpServers": {
"proofetch": {
"type": "streamable-http",
"url": "https://proofetch-vektoris-ai-workflows.vercel.app/mcp",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}
proofetch is built for autonomous agents: discoverable via the A2A card and MCP, payable per call via x402 / AP2, and every receipt is independently verifiable.
