Vouch MCP

Vouch provides a per-call counterparty risk score for autonomous AI agent payments. It assesses trust and reputation using threat feeds, domain signals, and a community-compounded reputation graph, allowing agents to verify merchants before transacting via x402 payments.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Vouch is a payment-trust gate for AI agents. BEFORE authorizing or sending a payment to a counterparty — a merchant, API, agent, wallet, or x402 resource — call `vouch_score` with the counterparty's URL or host to get a 0-100 trust score and a risk band (low/medium/high/critical). Treat medium-or-higher risk as a reason to pause or seek user confirmation before paying. After a transaction, use `vouch_report` to flag a host that turned out to be a scam or vouch for one that was legitimate — this strengthens the shared reputation graph for everyone. Both tools are free. For the full explainable reasons plus a signed, verifiable attestation (proof of due diligence for audits/disputes), call the paid POST /v1/check endpoint over x402.

Tools

2 advertised

vouch_score
Advertised by the server during the last successful anonymous check.

Check whether a counterparty is SAFE TO PAY before sending money. Given a URL or host, returns a 0-100 trust score and risk band (low/medium/high/critical), detecting scams, phishing, and known-malicious endpoints via threat feeds, domain risk heuristics, and a community reputation graph. Call this before paying any merchant, API, agent, or x402 resource. Free — for the full explainable reasons AND a signed, verifiable attestation (proof of the check for audit/disputes), call the paid POST /v1/check endpoint via x402.

vouch_report
Advertised by the server during the last successful anonymous check.

Report a host as a scam/bad actor ('flag') or as trustworthy ('vouch'), improving Vouch's community reputation graph for everyone's future payment-trust checks. Free.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http vouch-mcp-workers https://vouch.futuronoti.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add vouch-mcp-workers --url https://vouch.futuronoti.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable vouch-mcp-workers in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "vouch-mcp-workers": {
      "url": "https://vouch.futuronoti.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "vouch-mcp-workers": {
      "type": "streamableHttp",
      "url": "https://vouch.futuronoti.workers.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start vouch-mcp-workers and inspect its tools.
VS Code configuration
{
  "servers": {
    "vouch-mcp-workers": {
      "type": "http",
      "url": "https://vouch.futuronoti.workers.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http vouch-mcp-workers https://vouch.futuronoti.workers.dev/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "vouch-mcp-workers": {
      "serverUrl": "https://vouch.futuronoti.workers.dev/mcp"
