OONI MCP — internet censorship & website reachability measurements from the

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

Tool	Description
ooni_site_reachability	Check whether a website is blocked or censored in a specific country, using OONI network measurements from volunteer probes. Returns counts of OK, anomalous, confirmed-blocked, and failed measurements over the window plus a blocking assessment — e.g. is bbc.com blocked in China, is twitter.com blocked in Iran. Great-Firewall / national-censorship / internet-freedom research.
ooni_blocking_trend	Daily time series of OONI censorship measurements for a website in a country — shows when blocking started, stopped, or intensified (e.g. Twitter in Iran day by day). Returns per-day OK / anomaly / confirmed-blocked counts.
ooni_app_blocking	Check whether a messaging or circumvention app is blocked in a country using OONI app-specific tests: WhatsApp, Telegram, Signal, Facebook Messenger, or Tor. Returns measurement counts and a blocking assessment, e.g. "is Telegram blocked in Iran", "is Tor reachable from Russia".
ooni_measurements	List recent raw OONI measurements for a domain and/or country — individual probe results with timestamp, network (ASN), anomaly/confirmed flags, and a link to the full measurement on OONI Explorer. Use after ooni_site_reachability to inspect specific blocking evidence.

Quick Start

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

{
  "mcpServers": {
    "ooni": {
      "url": "https://gateway.pipeworx.io/ooni/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/ooni/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Ooni data" })

The gateway picks the right tool and fills the arguments automatically.
