SpeedOf.Me MCP Server

Official MCP server for SpeedOf.Me. Lets an AI agent run a real internet speed test and read the result: download, upload, latency and jitter, measured against 130+ global edge servers.

"How fast is my connection right now?"
→ 187.4 Mbps down / 41.2 Mbps up / 11 ms latency / 1.8 ms jitter (San Jose)

Tools

Tool	What it does
`run_speed_test`	Runs a live speed test and returns download, upload, latency and jitter
`get_test_history`	Returns previous results from local history

Resource	Contents
`speedofme://history`	Recent test results (JSON)
`speedofme://config`	Current configuration and status

Quick start

1. Get a free API secret

2. Add the server to your MCP client

{
  "mcpServers": {
    "speedofme": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@speedofme/mcp"],
      "env": {
        "SOM_API_SECRET": "SOM_SECRET_xxx"
      }
    }
  }
}

Claude Code, one command:

claude mcp add speedofme --env SOM_API_SECRET=SOM_SECRET_xxx -- npx -y @speedofme/mcp

VS Code (Copilot) uses servers instead of mcpServers in .vscode/mcp.json; the rest of the block is identical. Cursor, Windsurf, Zed, Cline, Continue, JetBrains and Goose all take the JSON above. Client-specific configs and agent-framework examples (LangChain, LlamaIndex, AutoGen, CrewAI, Semantic Kernel) are in the integration docs.

3. Restart the client and ask for a speed test.

Tool reference

`run_speed_test`

Parameter	Type	Default	Description
`tests`	string[]	all	Which tests to run: `download`, `upload`, `latency`
`sustainTime`	number	6	Seconds to sustain each sample (1-8). Lower is faster, higher is more accurate
`testTimeout`	number	300	Wall-clock cap for the whole run, in seconds. 0 disables, min 30, max 1800

The tool replies with formatted text. The underlying result looks like this:

{
  "testId": "abc123",
  "download": 150.5,
  "upload": 45.2,
  "latency": 12,
  "jitter": 2.3,
  "testServer": "San Jose",
  "timestamp": "2026-08-18T10:30:00Z"
}

Speeds are Mbps, latency and jitter are milliseconds.

`get_test_history`

Parameter	Type	Default	Description
`limit`	number	10	Maximum number of results
`since`	string	none	ISO date string. Only results after this time

History is stored locally in ~/.speedofme/history.json, capped at 1 MB (roughly 2,600 results).

Also a CLI

The same package runs standalone, no MCP client required:

SOM_API_SECRET=SOM_SECRET_xxx npx -y @speedofme/mcp --progress   # human readable
SOM_API_SECRET=SOM_SECRET_xxx npx -y @speedofme/mcp --json       # for scripts
npx -y @speedofme/mcp history --limit 5                          # past results
npx -y @speedofme/mcp --help

And as a Node SDK:

const { SpeedTest } = require('@speedofme/mcp');

const test = new SpeedTest({ apiSecret: process.env.SOM_API_SECRET });
const result = await test.run();          // { download, upload, latency, jitter, ... }

Full CLI and SDK options are documented on npm.

How the measurement works

SpeedOf.Me has measured what we call Real-World Speed the same way since 2011. Rather than blasting a fixed payload, the test downloads progressively larger samples, starting at 128 KB, until one takes longer than the sustain time (6 seconds by default), and reports the rate of that final sample. Upload works the same way in reverse, and latency and jitter come from 10 round-trip samples. Tests run against the nearest of 130+ edge locations, so an agent gets the same number a person would see in the browser.

Every test also lands in your dashboard with geographic, device and platform breakdowns, and usage against your plan.

Details: how it works.

Requirements

Node.js 18 or newer
A SpeedOf.Me API account and secret (free tier available)
