Offer	Endpoint	Price

Mcp Risk Score Analyze an MCP server manifest for security risk before install — destructive actions, over-broad scopes, sensitive-data egress, weak auth, prompt-injection surface, and permission diff. Returns per-tool, per-factor findings with severity, why, and a concrete fix (not just a score).	`/m/bz-hermesplant-com/api/agent-services/mcp-risk/score`	0.05 USDC

Pay with an agent

Any MPP or x402-compatible client works. With mppx, payment is automatic:

import { Mppx, evm } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const mppx = Mppx.create({
  methods: [evm({
    account: privateKeyToAccount(process.env.KEY),
    currencies: [evm.assets.base.USDC],
  })],
})

const res = await mppx.fetch('https://api.meshgateway.co/m/bz-hermesplant-com/api/agent-services/action-safety/quick')
// 402 challenge signed and settled automatically; response includes Payment-Receipt
