## Description
SEO and AI-visibility checks an agent pays for per call, with no account: keyword research, on-page audits, AI-citation checks across ChatGPT, Claude, Gemini and Perplexity, plus rank, SERP, domain and backlink data. 17 endpoints at $0.005–0.30 each, settled in USDC on Solana over x402; a failed call is never charged. Install: npx -y citable-mcp.

## Tools
Capabilities this server exposes over MCP:

- **citable_prices** — endpoints, prices, wallet, balance, spend cap — call this first
- **citable_connect** — a sign-in link for funding without touching crypto
- **citable_keyword_suggest** — autocomplete expansions and questions for a seed
- **citable_serp** — the Google results page for a keyword
- **citable_onpage_audit** — citability score for one URL, 20 checks, ordered fixes
- **citable_rank_check** — where a domain ranks on Google for a keyword, plus the top 10
- **citable_keyword_metrics** — volume, CPC, competition, difficulty and intent for 1–20 keywords
- **citable_domain_overview** — a domain's organic footprint: keywords ranked, top positions, traffic
- **citable_domain_history** — that footprint month by month
- **citable_domain_keywords** — the keywords a domain ranks for, with month-over-month movement
- **citable_keyword_ideas** — related keywords for a seed, with volume and difficulty
- **citable_ai_visibility** — which AI engines cite a domain for your question, and who they cite instead
- **citable_keyword_research** — one seed → keywords and questions, merged and priced
- **citable_backlinks** — backlink totals, referring domains, domain rank
- **citable_ai_mentions_trend** — monthly AI mentions for a domain, with the trend
- **citable_ai_share_of_voice** — 2–10 domains compared inside the AI-answer index
- **citable_top_cited_pages** — the domain's pages AI answers cite most

- **citable_citability_report** — audit + AI visibility + top cited pages in one call ($0.43 apart)

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json

  "citable-mcp": {
    "command": "npx",
    "args": ["-y","citable-mcp"]
  }
}
```

## Documentation & README

# citable-mcp

MCP server for [Citable](https://citable.run) — SEO and AI-visibility data an agent can buy
by the call. Each tool pays for itself in USDC on Solana over [x402](https://x402.org) from a
wallet on your machine: no account, no API key, no subscription. $0.005–0.30 per call, and a
failed call is never charged.

The code that signs those payments is in this repo — `server.ts` is the whole server.

## Install

```bash
claude mcp add citable -- npx -y citable-mcp     # Claude Code
codex mcp add citable -- npx -y citable-mcp      # Codex
```

Cursor, Claude Desktop, or any MCP client — `mcp.json`:

```json
{
  "mcpServers": {
    "citable": {
      "command": "npx",
      "args": ["-y", "citable-mcp"],
      "env": { "CITABLE_MAX_PRICE": "0.30" }
    }
  }
}
```

Node ≥ 20.18, or `bunx citable-mcp`.

## Skills

The server gives the agent the tools; the open-source
[skills pack](https://github.com/zaialamm/seo-ai-visibility-skills) teaches it the workflows —
a guided `start`, citability audits that apply fixes in your code, keyword briefs, rank
tracking with history in your repo, AI-citation checks, and a `full-check` that runs end to
end under one budget consent. 13 skills, 5 of them free.

```bash
npx skills add zaialamm/seo-ai-visibility-skills          # any agent: Codex, Cursor, Gemini CLI, 17+
/plugin marketplace add zaialamm/seo-ai-visibility-skills # Claude Code plugin (bundles this server)
```

## Wallet

Start with `citable_prices` — it reports the wallet, its balance, and how to fund it. Two ways:

- **Sign in, no crypto needed.** `citable_connect` returns a link: sign in at citable.run with
  Google or email, add a few dollars, click Connect. The agent then pays from that wallet.
- **Keypair, if you already use Solana.** With nothing configured the server creates
  `~/.config/citable/agent.json` on first need and shows the address. Send it USDC on Solana —
  no SOL required, the x402 facilitator covers the network fee — or point `CITABLE_WALLET` at
  a funded keypair.

## Config

| Env | Default | Meaning |
|---|---|---|
| `CITABLE_WALLET` | `~/.config/citable/agent.json` | keypair JSON path, or the JSON byte array itself, holding mainnet USDC. Created when first needed |
| `CITABLE_MAX_PRICE` | `0.30` | refuse any single call priced above this many USD; nothing is signed |
| `CITABLE_API` | `https://citable.run` | base URL |

Every paid result carries `_payment.transaction`, the on-chain settlement. A call above the
cap, or without funds, returns a structured error and pays nothing.

## How a call works

1. The tool requests the endpoint. Citable answers `402` with the price, the USDC mint and
   the pay-to address.
2. The server signs a USDC transfer for exactly that amount — only if it is at or below
   `CITABLE_MAX_PRICE` — and retries with the payment header.
3. The facilitator settles on Solana in about 400 ms and the endpoint returns `200`.

The keypair is read from disk and used only to sign these transfers. Nothing else leaves
your machine, and Citable stores nothing about you: the wallet is the only identity.
