---

This is the EVIDIQ Model Context Protocol server — the remote endpoint that exposes EVIDIQ's trust tools to any MCP-capable agent. It verifies a counterparty's capability, scores its risk, checks its on-chain reputation, and returns a signed Trust Report so an agent can decide to proceed, escrow, or walk away — before any value moves.

Live at https://evidiq.dev/mcp (Streamable HTTP).

Tools

Tool	Access	What it returns
how_to_install	free	How to connect the server or install the skill.
get_evidiq_skill	free	The latest EVIDIQ Agent Skill (open-skill markdown).
verify_agent	paid (x402)	A Trust Report: score (0–100), tier, risk breakdown, recommendation, and a signed attestation anchored on 0G.

Resource: evidiq://skill — the live skill document.

Pay-per-call (x402)

verify_agent is metered per call over x402. Unauthenticated calls receive an HTTP 402 challenge (scheme exact, EIP-3009); sign it and retry with a PAYMENT-SIGNATURE header. Pricing/discovery is at GET /x402. The free tools stay free, and the gate is a no-op until payment is configured, so the server runs in either mode.

How a check runs

probe endpoint  →  score identity · capability · reputation · risk
               →  AI risk analysis (GLM via 0G compute / TEE)
               →  attest: keccak256(report) + 0G Storage + EIP-191 signature
               →  Trust Report

Source layout

Path	Description
route.ts	MCP route handler — registers the tools + resource; mounts at /mcp.
lib/x402/	x402 pay-per-call gate (config, challenge, verify, facilitator).
lib/trust/	Endpoint probe, deterministic scoring, and report types.
lib/og/	0G Storage, compute (GLM / TEE), and attestation.
lib/skill.ts, lib/install.ts	The skill document + install instructions.
lib/request-context.ts	Per-request base URL + payment context.

The canonical deployment runs this handler as a Next.js Route Handler in the EVIDIQ platform. The skill it serves lives at evidiq/evidiq-skill.
