Security Report
HOGSWAP MCP server is well-designed with strong security fundamentals. The server properly handles authentication through optional API keys, never touches user private keys (returning only unsigned transactions), and implements proper input validation with Zod schemas. Code is clean and well-documented. Minor findings relate to logging practices and error handling details that do not represent material security risks. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

hogswap-mcp
MCP server exposing HOGSWAP to AI
agents: DEX-aggregated quotes, unsigned swap builds, zero-human API-key
self-registration, and the star — pay_x402_invoice: pay any
Algorand-settled x402 invoice with any 1–4 assets you hold, via an
exact-out router swap. API reference:
hogswap-v1.liquihog.dev/reference.
Building an app rather than an agent? Official SDKs:
hogswap-js-sdk (npm)
and hogswap-py-sdk (PyPI).
Strictly non-custodial: every transaction-producing tool returns unsigned groups; you sign with your own wallet tooling and submit yourself. Never give any tool a mnemonic or private key.
Run (stdio)
npm install
HOGSWAP_API_KEY=hsk_... node src/index.mjs # key optional
Claude Code: claude mcp add hogswap -e HOGSWAP_API_KEY=hsk_... -- node <abs-path>/src/index.mjs
| Env | Meaning |
|---|---|
HOGSWAP_API_URL | API base (default https://hogswap-v1.liquihog.dev) |
HOGSWAP_API_KEY | hsk_ bearer key; self-issue via the register_agent / verify_registration tools |
Tools
Free (no key): list_payable_assets, get_quote, register_agent,
verify_registration. get_quote takes optional max_legs (1–16)
to cap total route legs, splits included — for replaying the route
under your own resource budget.
🔑 Require a HOGSWAP API key (set HOGSWAP_API_KEY, or self-issue one
with register_agent → sign → verify_registration): build_swap,
pay_x402_invoice, get_credit_offer, get_balance, plus the watch
tools set_watch / list_watches / delete_watch (standing
server-side price/target alerts — free of charge, but namespaced by
key). Without a key these return an auth error, not a build.
Watch fires are numbers-only hints — re-quote with get_quote when
one fires. From MCP, poll list_watches; outside MCP the server
pushes events over SSE at GET /watches/stream.
pay_x402_invoice returns two groups (swap, then payment) — sign all
txns in one pass, submit the groups in order; the swap's on-chain
floor guarantees the payment is funded. A HOGSWAP credit top-up's 402
offer is itself an x402 invoice: feed its accepts[0] (with the
note nonce) straight into pay_x402_invoice to buy credits with
any asset.
Remote (no local process)
The same 12 tools are served over MCP Streamable HTTP at
https://hogswap-v1.liquihog.dev/mcp/ — hosted by the HOGSWAP API
itself, no local process needed. Use the trailing slash — the
bare /mcp 307-redirects to /mcp/, costing an extra round trip per
call. Point any remote-capable MCP client at it; pass your key as
Authorization: Bearer hsk_... (the Claude API connector's
authorization_token does exactly this).
Smoke tests
HOGSWAP_API_KEY=hsk_... \
SMOKE_PAY_TO=<any USDC-opted addr> node test/smoke.mjs # stdio
HOGSWAP_API_KEY=hsk_... \
SMOKE_PAY_TO=<any USDC-opted addr> node test/smoke-remote.mjs # remote
Both default to the live API; set HOGSWAP_API_URL (stdio) or
MCP_URL (remote) to point them at another instance. Read-only +
build-only; nothing is signed or broadcast.
