Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "satrank": {
      "command": "npx",
      "args": [

      ],
      "env": {
        "SATRANK_API_BASE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add satrank --env SATRANK_API_BASE=your-value -- npx -y satrank-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "satrank": {
      "command": "npx",
      "args": [

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {

      "env": {
        "SATRANK_API_BASE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

SATRANK_API_BASE env
Hosted SatRank API endpoint. Default https://satrank.dev for the public oracle.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is SatRank — Lightning trust + audit oracle safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

SatRank

Lightning trust oracle for AI agents on L402. Bitcoin-pure.

What this does

Crawls the L402 ecosystem (l402.directory + RSS + DNS) to build a catalogue of paid endpoints.
Probes each endpoint, classifying outcomes across 5 stages: challenge / invoice / payment / delivery / quality.
Scores every (endpoint, stage) pair as a streaming Beta(α, β) posterior. The end-to-end success probability is the product of stage means.
Ranks candidates on POST /api/intent (paid 2 sats via L402): an agent passes a category + budget + SLA, gets back the top-K endpoints with full Bayesian breakdown.
Publishes signed Nostr trust assertions (kind 30782) so any agent can cache / verify SatRank's output offline.

Public endpoints

Doc surfaces:

GET  /                                 landing page (static HTML)

GET /methodology technical reference (static HTML) GET /api API reference (static HTML) GET /openapi.json OpenAPI 3.0 spec (machine-readable)

Functional API (nine routes — POST /api/intent is the only L402-gated one):

POST /api/intent                       paid, 2 sats via L402

POST /api/deposit free, mint a multi-use deposit macaroon (10–10000 sats, 30-day TTL) GET /api/deposit/:macaroon_id free, read remaining balance GET /api/services/:url_hash free, per-endpoint score snapshot GET /api/services/categories free, list of catalogue categories GET /api/services/best free, top-3 per category (5-min cache) GET /api/oracle/budget free, last 24h revenue + paid-probe spend GET /health free, liveness GET /.well-known/satrank-key free, oracle pubkey for offline verify

Deposit macaroons let an agent pre-pay N sats once and use the bearer preimage across many /api/intent calls without a Lightning round-trip per call. Authorization: L402 deposit_ : .

MCP

Three tools for any MCP-compatible AI runtime (Claude Code, Cursor, Codex, n8n):

intent              forwards POST /api/intent (paid)

get_endpoint_score forwards GET /api/services/:url_hash (free) verify_assertion offline Schnorr verification of kind 30782 (no network)

Install in Claude Code:

claude mcp add satrank -- npx -y satrank-mcp

Self-hosters point SATRANK_API_BASE at their own deployment.

Run it

cp .env.example .env

minimum: set DATABASE_URL

npm install npm run build npm start

For paid probes + paid /api/intent gate, set LND_REST_URL + LND_MACAROON_HEX + L402_MACAROON_SECRET. For Nostr trust assertions, set NOSTR_PRIVATE_KEY.

Scoring math

For each (endpoint, stage), maintain a Beta(α, β) posterior with α₀ = β₀ = 1 (uniform prior). On every observation:

success → α += 1
failure → β += 1

Stage mean: α / (α+β). 95% credible interval via Wilson (closed-form). End-to-end success: ∏ stage_means across the 5 stages, assuming stage independence.

is_meaningful is true iff the challenge stage has at least MEANINGFUL_N_OBS_MIN observations. The challenge stage is observed on every probe (free or paid), so its n_obs converges fastest. p_e2e remains the honest end-to-end product separately.
