ProbeOps MCP Server

MCP server for running infrastructure diagnostics from 6 global regions. SSL checks, DNS lookups, ping, whois, port checks, traceroute, latency tests, and more — each executed simultaneously from US East, US West, EU Central, Canada, India, and Australia.

Works instantly — no API key required. Run npx @probeops/mcp-server and get 11 diagnostic tools with 10 free calls per day. Add an API key to unlock all 21 tools, 6 regions, and higher limits.

Works with Claude Code, Codex, Cursor, Windsurf, Cline, and any Model Context Protocol compatible client.

Quick Start

Option 1: Try It Now (No API Key)

Claude Code:

claude mcp add probeops -- npx -y @probeops/mcp-server

Codex:

codex mcp add probeops -- npx -y @probeops/mcp-server

Cursor / Windsurf / Cline (add to .mcp.json or your client's MCP config):

{
  "mcpServers": {
    "probeops": {
      "command": "npx",
      "args": ["-y", "@probeops/mcp-server"]
    }
  }
}

That's it. You get 11 tools with 10 calls per day and 2 probe regions — no signup, no configuration.

Option 2: Full Access (Free API Key)

Claude Code:

claude mcp add probeops -e PROBEOPS_API_KEY=your-key -- npx -y @probeops/mcp-server

Codex (add to ~/.codex/config.toml):

[mcp_servers.probeops]
command = "npx"
args = ["-y", "@probeops/mcp-server"]

[mcp_servers.probeops.env]
PROBEOPS_API_KEY = "your-api-key-here"

Cursor / Windsurf / Cline:

{
  "mcpServers": {
    "probeops": {
      "command": "npx",
      "args": ["-y", "@probeops/mcp-server"],
      "env": {
        "PROBEOPS_API_KEY": "your-api-key-here"
      }
    }
  }
}

Demo Mode vs Full Access

	Demo Mode (no key)	Free Tier (with key)	Professional

What You Get

21 infrastructure diagnostic tools, each running from up to 6 regions simultaneously. Plus geo-proxy browsing and account management.

Every diagnostic tool call returns per-region results and a quota footer showing remaining usage.

Diagnostic Tools (14)

Tool	What it does	Example input

DNS Shortcuts

These call dns_lookup with a preset record_type so you don't have to remember record type names:

Tool	Equivalent to
`mx_lookup`	`dns_lookup` with `record_type: "MX"`
`txt_lookup`	`dns_lookup` with `record_type: "TXT"`
`ns_lookup`	`dns_lookup` with `record_type: "NS"`
`cname_lookup`	`dns_lookup` with `record_type: "CNAME"`

Geo-Proxy Browsing

Tool	What it does	Example input
`get_geo_proxy`	Get proxy credentials for a region. Use with Playwright or any HTTPS proxy client	`{ "region": "eu-central" }`
`geo_browse`	Browse a URL from a region using a real browser. Returns page content and/or screenshot	`{ "url": "https://example.com", "region": "ap-south" }`

Account

Tool	What it does
`account_status`	Current quota usage (minute/hour/day/month), subscription tier, active proxy token

Resources

URI	Description
`probeops://regions`	Probe regions with location, country, and node count
`probeops://proxy-regions`	Geo-proxy regions with FQDNs and proxy URLs
`probeops://usage`	Current API usage, remaining quota, active token status

Global Regions

All diagnostic tools run from these 6 regions simultaneously:

Region Code	Location	Country
`us-east`	Ashburn, Virginia	United States
`us-west`	Boardman, Oregon	United States
`eu-central`	Helsinki	Finland
`ca-central`	Montreal	Canada
`ap-south`	Mumbai	India
`ap-southeast`	Sydney	Australia

Geo-Proxy Token Management

The server manages proxy tokens automatically:

Token State	Action	Quota Cost
> 5 min remaining	Reuse cached token	0
0-5 min remaining	Auto-extend +1 hour	1 unit
Expired or no token	Generate new token	1 unit

A single token works across all 6 regions. Switching regions does not consume quota.
Daily quota = total hours of proxy browsing per day.
Quota resets at midnight UTC.

Development

git clone https://github.com/kumarprobeops/probeops-mcp-server.git
cd probeops-mcp-server
npm install
npm run build

Test locally:

PROBEOPS_API_KEY=your-key node dist/index.js

Requirements

Node.js >= 18.0.0
Playwright (optional) - only needed for geo_browse screenshots
```
npx playwright install chromium
```
Without Playwright, geo_browse falls back to HTTP fetch (raw HTML, no screenshots).

FAQ

Q: How is this different from running curl or dig locally? Every check runs from 6 global regions simultaneously. You see DNS propagation, latency, and availability from the perspective of real users worldwide, not your local network.

Q: Do I need to install anything besides Node.js? No. npx -y @probeops/mcp-server handles everything. Playwright is optional (only for geo_browse screenshots).

Q: Can I use this in CI/CD pipelines? Yes. Set PROBEOPS_API_KEY as an environment variable and call the MCP server from any MCP-compatible tool.

Q: Is the API key sent securely? Yes. All communication uses HTTPS. The key is sent via the X-API-Key header, never in URLs or logs.
