## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-ooni).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 609 tokens (~152/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `ooni_site_reachability` (~172 tokens)

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.

Input parameters:

- `country` (string, required): 2-letter country code, e.g. "CN", "IR", "RU".
- `days` (number|string): Lookback window in days (default 30, max 365).
- `domain` (string, required): Website domain, e.g. "www.bbc.com" or "twitter.com". A full URL is accepted (the host is extracted).

### `ooni_blocking_trend` (~115 tokens)

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.

Input parameters:

- `country` (string, required): 2-letter country code, e.g. "IR".
- `days` (number|string): Lookback window in days (default 30, max 365).
- `domain` (string, required): Website domain, e.g. "twitter.com".

### `ooni_app_blocking` (~136 tokens)

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".

Input parameters:

- `app` (string, required): One of: whatsapp | telegram | signal | facebook_messenger | tor.
- `country` (string, required): 2-letter country code, e.g. "IR", "RU", "CN".
- `days` (number|string): Lookback window in days (default 30, max 365).

### `ooni_measurements` (~133 tokens)

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.

Input parameters:

- `confirmed_only` (boolean): Only measurements with confirmed blocking fingerprints.
- `country` (string): 2-letter country code filter, e.g. "IR".
- `domain` (string): Website domain, e.g. "twitter.com".
- `limit` (number|string): Max results (1-50, default 10).

## Common questions

### What is the Ooni MCP server?

Ooni is an MCP server listed in the public MCP registry as io.github.pipeworx-io/ooni. OONI MCP, internet censorship & website reachability measurements from the Open Observatory of… This page covers its npm package (@pipeworx/mcp-ooni).

### Is the Ooni MCP server safe to use?

Ooni scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Ooni MCP server expose?

Ooni exposes 4 tools: ooni_site_reachability, ooni_blocking_trend, ooni_app_blocking, ooni_measurements. Their descriptions and schemas cost roughly 556 tokens of context every time the server is loaded.

### Is the Ooni MCP server still maintained?

Ooni is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Ooni MCP server under?

Ooni declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Ooni MCP server?

VerifyMCP ran 16 checks on Ooni, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
