# PikaSim MCP Server

> Buy eSIMs from an AI agent — no account, no email, no KYC. Anonymous data plans, **real carrier phone numbers**, and **SMS verification numbers** across 190+ countries, settled in crypto from a prepaid agent wallet.

PikaSim is a **remote, hosted MCP server** (Streamable HTTP). You don't run any code — just point your AI agent at the URL and it can search plans, check coverage, get pricing, and (with a funded agent wallet) purchase eSIMs and SMS numbers autonomously.

- **Browse (no auth):** `https://pikasim.com/mcp`
- **Purchase (OAuth):** `https://pikasim.com/mcp/wallet`
- **Transport:** Streamable HTTP (JSON-RPC over HTTP POST)
- **Docs:** https://pikasim.com/mcp-docs?utm_source=github_pikasim_mcp
- **Agent wallet:** https://pikasim.com/agent-wallet?utm_source=github_pikasim_mcp
- **Browsing needs no key.** Purchasing connects a prepaid agent wallet via one-click OAuth (or an `ak_live_` key on CLI clients).

## Install as an agent skill

This repo also ships a [`pikasim` agent skill](skills/pikasim/SKILL.md) — an
installable instruction package that teaches any skill-capable agent (Claude
Code, claude.ai, and other SKILL.md-compatible hosts) when and how to buy
connectivity from PikaSim, including the no-MCP REST fallback and the
cold-start wallet flow:

```bash
npx skills add codebruinc/pikasim-mcp
```

or copy `skills/pikasim/` into your agent's skills directory (e.g.
`~/.claude/skills/pikasim/`).

---

## Quick start

Add PikaSim to your AI agent's MCP config:

```json
{
  "mcpServers": {
    "pikasim": {
      "type": "streamable-http",
      "url": "https://pikasim.com/mcp"
    }
  }
}
```

That's it — your agent can now search data and phone-number eSIM plans, check country coverage, and get pricing for 190+ countries. **No API key needed for browsing.**

To **purchase** too, connect `https://pikasim.com/mcp/wallet` instead — it triggers a one-click OAuth flow where you authorize a free, prepaid [agent wallet](https://pikasim.com/agent-wallet) by pasting your wallet code (no key handling, no account, no email). See [Authentication](#authentication).

---

## Fully autonomous: from zero to buying, no human

A terminal or headless agent (Claude Code, a script, an autonomous loop) needs **no browser and no person**. Connect the keyless `https://pikasim.com/mcp` and onboard in four calls:

```jsonc
// 1. The agent creates its own wallet — returns a wallet code, an ak_live_ key,
//    and a small spend-only welcome credit. No account, email, KYC, or browser.
{ "tool": "create_wallet", "arguments": { "acceptTos": true } }

// 2. Reconnect with the returned key:  Authorization: Bearer ak_live_...
//    (or use the URL https://pikasim.com/mcp/ak_live_YOUR_KEY)

// 3. Confirm the welcome credit is there
{ "tool": "check_balance", "arguments": {} }          // -> $1.00

// 4. Buy — the welcome credit covers a first eSIM data plan (from $0.75); SMS numbers need a $1 deposit
{ "tool": "order_sms_verification", "arguments": { "serviceId": "817", "countryId": "2" } }
```

That's the whole loop: **no human, no browser, no card, no account.** When the agent needs more funds, `create_deposit` returns Lightning, USDT, Monero, and Bitcoin destinations it can pay itself. Save the wallet code and key from the `create_wallet` response — each is shown once.

## Three product lines

Don't assume "eSIM" means data-only. PikaSim sells:

1. **Data eSIMs** — anonymous data plans across 190+ countries, from **$0.75**. Discover with `search_esim_packages` / `check_country_coverage`; buy with `purchase_esim`.
2. **Phone-number eSIMs** — a **real carrier phone number** (not VoIP) with voice calls, SMS, and data. US plans give a real **+1** number on AT&T and T-Mobile; global plans cover 157 countries. Discover with `search_phone_plans`; buy with `purchase_phone_plan`.
3. **SMS verification numbers** — receive-only numbers for getting verification codes, no eSIM involved. **Quick SMS**: a one-time code on a temporary number, auto-refund if nothing arrives in 20 minutes (`search_sms_services` → `get_sms_service_countries` → `order_sms_verification` → poll `check_sms_verification`). **Long-term rentals**: keep a number for days to months and receive multiple SMS, with live stock shown per duration (`list_sms_rentals` → `rent_sms_number` → `get_sms_rental_messages` / `extend_sms_rental`).

`search_esim_packages` and `check_country_coverage` return **both** eSIM lines in separate buckets. Package codes appear in `[brackets]` — pass them to the matching purchase tool.

## Setup guides

PikaSim is a remote MCP server at `https://pikasim.com/mcp`. The config key and steps differ per client.

### Claude Desktop

Remote servers are added as **Connectors**, not via `claude_desktop_config.json`. Go to **Settings → Connectors → Add custom connector**. To browse, paste `https://pikasim.com/mcp`. To **purchase**, paste `https://pikasim.com/mcp/wallet` and click **Connect** — Claude opens a PikaSim page where you authorize a wallet by pasting your wallet code (one-click OAuth, no key in the URL).

### Claude Code (CLI)

```bash
# Browse only (also lets the agent self-onboard via the create_wallet tool)
claude mcp add --transport http pikasim https://pikasim.com/mcp

# With purchasing via key (recommended for headless/terminal agents)
claude mcp add --transport http pikasim https://pikasim.com/mcp \
  --header "Authorization: Bearer ak_live_YOUR_KEY"

# With purchasing via OAuth: add the wallet URL, then run /mcp inside Claude
# Code and pick "Authenticate" — a browser opens the PikaSim consent page
# where you paste your wallet code
claude mcp add --transport http pikasim https://pikasim.com/mcp/wallet
```

**No wallet yet?** Connect the browse URL above and ask the agent to call `create_wallet` — it mints a wallet + `ak_live_` key + welcome credit in one call, then reconnect with the key (`--header "Authorization: Bearer ak_live_…"`). Fully autonomous, no browser. See [Fully autonomous](#fully-autonomous-from-zero-to-buying-no-human).

### Cursor / Windsurf / other JSON-config clients

```json
{
  "mcpServers": {
    "pikasim": {
      "type": "streamable-http",
      "url": "https://pikasim.com/mcp"
    }
  }
}
```

To purchase from clients that support MCP OAuth (Cursor does), use `https://pikasim.com/mcp/wallet` as the URL instead — the client opens the PikaSim consent page where you paste your wallet code.

### ChatGPT (custom connector)

Add a custom connector with URL `https://pikasim.com/mcp` to browse, or `https://pikasim.com/mcp/wallet` to purchase (the wallet URL triggers OAuth — authorize by pasting your wallet code).

## Authentication

Browsing is open at `https://pikasim.com/mcp`. To purchase, connect `https://pikasim.com/mcp/wallet`, which supports two auth methods:

1. **OAuth (recommended, for app clients like Claude Desktop / ChatGPT):** connecting the wallet URL triggers OAuth 2.1 (Dynamic Client Registration + PKCE). You're sent to a PikaSim consent page where you paste your **wallet code** to authorize. The client receives a revocable access token — never your wallet code or `ak_live_` key. No account, no email, no KYC.
2. **Bearer key (for CLI clients):** send `Authorization: Bearer ak_live_YOUR_KEY`.

The plain `https://pikasim.com/mcp` URL is **browse-only** — but the `create_wallet` tool works there, so an agent can mint its own wallet + key + welcome credit with no browser (see [Fully autonomous](#fully-autonomous-from-zero-to-buying-no-human)). A human can instead create a wallet at **https://pikasim.com/agent-wallet?utm_source=github_pikasim_mcp** (save the wallet code; it's the only way back in).

### Wallet, in brief

- Prepaid, crypto-funded balance. Retail pricing. Minimum deposit **$1** — and new wallets carry a small spend-only welcome credit, so a first eSIM data plan (from $0.75) needs no deposit at all. SMS verification numbers always need a deposit.
- Fund via `create_deposit` — it returns **agent-payable** Lightning, USDT (TRC-20), Monero, and Bitcoin destinations inline (an agent holding crypto pays without a human), plus a payment page (card + 50+ altcoins) for a human.
- No personal account, email, or KYC required.
- Welcome credit is spend-only (never withdrawable); deposits are.

> There's also a separate **reseller** program at https://pikasim.com/reseller — a B2B track with its own `pk_live_` key and a 10% discount. Reseller keys also work on this MCP server at wholesale pricing.

## Example

```jsonc
// 1. Find data plans for Japan
{ "tool": "search_esim_packages", "arguments": { "country": "JP", "type": "data" } }

// 2. Get a real US phone number plan
{ "tool": "search_phone_plans", "arguments": { "country": "US" } }

// 3. Check your wallet, then buy (needs ak_live_ key)
{ "tool": "check_balance", "arguments": {} }
{ "tool": "purchase_esim", "arguments": { "packageCode": "PACKAGE_CODE_FROM_SEARCH" } }
```

## Rate limits & errors

- Public browsing is rate-limited per IP. Authenticated tools are scoped to your wallet.
- Errors return a clear message (e.g. insufficient balance → fund via `create_deposit` or the wallet page).

## For registries (Dockerfile)

You do **not** need Docker to use PikaSim — just point your client at the URL above. The included [`Dockerfile`](Dockerfile) exists only so registries (e.g. [Glama](https://glama.ai/mcp/servers/codebruinc/pikasim-mcp)) can start a container, speak MCP over stdio, and introspect the tool set. It runs [`mcp-remote`](https://www.npmjs.com/package/mcp-remote), which bridges a local stdio client to the hosted Streamable HTTP endpoint. All public tools are discoverable with no key.
