Overview

AI-generated overview

A remote MCP server that scans TCP ports on a host and returns open/closed status and response times, paid per call via x402 micropayments.

What you can do
Scan TCP ports on a hostname or IP address, choosing a custom port list or the 16 common defaults (21, 22, 25, 53, 80, 110, 143, 443, 993, 995, 3306, 3389, 5432, 6379, 8080, 8443). Get back JSON with each port's status, response time, open count, total scanned and scan duration. Use results for server reconnaissance, firewall verification, service availability checks and infrastructure auditing.
When to use it
When an assistant needs to check which TCP ports are open on a host, confirm firewall rules, verify that a service is reachable, or do light infrastructure auditing. Not intended for DNS lookups, SSL certificate checks or HTTP header analysis.
Requirements
A remote MCP endpoint added by URL to an MCP client; no API key or signup. Each call is paid in USDC on Base L2 through the x402 protocol, so an x402-aware client or wallet that can sign the payment challenge is needed. Network access to the endpoint is required.
Before you install
Every scan costs money (listed at $0.008 per call) in USDC on Base, so an assistant could spend funds without a clear per-call confirmation. Scanning hosts you do not own or administer may be unauthorized or against provider policy. The host you submit is sent to a third-party service, and payment goes through Coinbase CDP and PayAI facilitators.

Installation

In SourceWeft

  1. Open Port Scanner API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fport-scanner/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Port Scanner API

[MCP Server] [x402] [License: MIT]

Scan TCP ports on any host -- check open/closed status, response time. 16 common ports by default. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "port-scanner": {      "url": "https://port-scanner.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://port-scanner.api.klymax402.com/api/scan" \  -H "Content-Type: application/json" \  -d '{"host":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

ToolMethodPathPriceDescription
network_scan_portsPOST/api/scan$0.008Scan common ports on a host to check which are open

network_scan_ports

Use this when you need to check which TCP ports are open on a host. Returns port status and response times in JSON.

Parameters

NameTypeRequiredDescription
hoststringyesThe hostname or IP address to scan
portsarraynoArray of port numbers to scan (default: [21,22,25,53,80,110,143,443,993,995,3306,3389,5432,6379,8080,8443])

Example response:

json
{"host":"example.com","ports":[{"port":80,"status":"open","responseTime":45},{"port":443,"status":"open","responseTime":52},{"port":22,"status":"closed","responseTime":null}],"openCount":2,"totalScanned":16,"scanDuration":1200}

When to use: server reconnaissance, verifying firewall rules, checking service availability, and infrastructure auditing.

Not for: DNS resolution (use network_lookup_dns), SSL certificate checks (use security_check_ssl), HTTP header analysis (use network_analyze_headers).

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
