x402 MCP for agents: crypto prices, funding, DeFi yields, Polymarket, Base RPC + MCP security.

io.github.rezearcher/tech-risk (MCP)

This MCP server for agents provides access to crypto-related market data, including crypto prices and funding, DeFi yields, and Polymarket information. It also works with Base RPC and includes “MCP security” as part of its stated scope, with a total of 22 tools available.

🛠️ Key Features

Crypto prices
Funding data
DeFi yields
Polymarket information
Base RPC support
MCP security
22 tools

🚀 Use Cases

Agent workflows that need up-to-date crypto price inputs
DeFi analytics that require yield and funding information
Decisioning that incorporates Polymarket data
Integrations that rely on Base RPC and MCP security

⚡ Developer Benefits

Use 22 dedicated tools for crypto/DeFi/Polymarket data retrieval
Integrate Base RPC-backed data sources with MCP

⚠️ Limitations

Scope is limited to the domains explicitly listed: crypto prices, funding, DeFi yields, Polymarket, and Base RPC/MCP security.

Captured live from the server via tools/list.

enrich_tech_risk

Security enrichment: tech-stack fingerprint + CVE mapping + EPSS + CISA KEV + verdict (clear/review/block) for a domain. Cost: $0.05 USDC per call (x402 micropayment).

Parameters2

domain	string	optional
techstack	array	optional

}

enrich_domain

Firmographic + tech-stack enrichment: RDAP registrant/registrar, DNS records, full subdomain enumeration + certificate-transparency history, tech-stack fingerprint, verdict (clear/review/block, based on domain age) for a domain. Cost: $0.05 USDC per call via the shared MCP payment gate (the direct HTTP endpoint GET /enrich/domain is $0.01 — MCP tools/call is gated at a flat $0.05 per request today).

Parameters1

domain

scan_mcp_server

Security-audit a target MCP server for prompt-injection / tool-poisoning. Fetches the server's advertised tools and statically analyzes each for hidden instructions, data-exfiltration hints, dangerous capabilities, cross-tool shadowing, and invisible-unicode payloads (OWASP LLM01/LLM08). Returns findings + a 0-100 risk score + verdict (clear/review/block). Cost: $0.05 USDC per scan via x402.

scan_mcp_preview
