Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

watch

delete_watch

Delete one of your watches by its client_key.

set_watch

Register a standing server-side watch (FREE, needs a key; idempotent upsert by client_key — re-registering replaces the watch and resets arming). kind='price': advisory µUSD threshold (asset_id, op gte/lte, threshold_usd_micro). kind='target': size-aware surrogate — would swapping amount_in of asset_in→asset_out deliver ≥ min_out? (margin_bps haircut, default 30; NO quote is run). Edge-triggered one-shot; re-arms after rearm_bps retreat + cooldown_s; ttl_s auto-expiry (default 86400) — refresh by re-upserting. Fires are numbers-only HINTS: re-quote with get_quote. Events push over SSE at GET /watches/stream (outside MCP); from MCP, poll list_watches.

balance

get_balance

Current HOGSWAP credit balance for your API key.

build

build_swap

Unsigned transaction group for a get_quote quote_id. Sign every txn with your own wallet and submit as one group. NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

credit

get_credit_offer

Create a credit top-up and get the x402 offer (HTTP 402 IS the payment instruction, not an error). Feed accepts[0] straight into pay_x402_invoice (keep the note nonce) to pay with any asset. Credits land ~1 block after payment.

pay

pay_x402_invoice

Pay ANY Algorand-settled x402 invoice with any 1-4 routable assets you hold, even holding none of the demanded asset. Pass the `accepts` entry you picked as `invoice` (keep its note!) plus your inputs (single input with no amount = minimum solved). Returns UNSIGNED groups — sign all in one pass, submit IN ORDER (swap first; its on-chain floor guarantees the payment is funded; holding the asset already = one direct payment). HOGSWAP credit top-up offers feed this verbatim. EVM invoices unsupported (no bridge). NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

payable

list_payable_assets

Assets accepted as payment inputs for pay_x402_invoice and credit top-ups (price-confidence gated; ALGO and USDC always included).

quote

get_quote

HOGSWAP swap quote across every Algorand DEX. Give amount (exact input) OR amount_out (exact output — minimum input is solved). Base units (µ); asset 0 = ALGO. Returns expected_out, route legs, and a quote_id for build_swap. expected_out is NET of the 5 bps routing fee; passing sender also returns router_fee_* fields and the wallet's HOG discount (hog_discount_pct, 100 = fully waived at 100 HOG). Optional sender enables HOG-holding fee discounts. Optional max_legs (1-16) caps TOTAL route legs, splits included — slightly worse price at size, 404 if nothing fits; forward (amount) quotes only.

register_agent

Self-service HOGSWAP API key, step 1 of 2 — zero human. Returns a challenge; sign its exact bytes with the address's key in YOUR wallet tooling, then call verify_registration. NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

value

value_lp_token

Value a liquidity-provider position. Give the LP token's asset id (free, no key) and optionally `amount` in LP BASE units — what the wallet holds — for its USD value and the redeemable amount of each underlying. Also identifies the issuing pool/DEX (and STAMM tier). Per-unit figures are per WHOLE LP token. Values are a proportional-share redemption at analytics prices: no slippage, no exit fee, NOT a market quote — fields are null rather than guessed when supply or a price is missing, so check before reporting a number.

verify

verify_registration

Self-service key issuance, step 2 of 2. Returns your hsk_ key ONCE — store it yourself; it is not recoverable and this server does not keep it. Send it on later calls as Authorization: Bearer, X-API-Key, or the api_key argument.

watches

list_watches

List your key's active watches (spec + arming/fired state), quota, and latest event seq. Poll this from MCP to see fires; SSE at GET /watches/stream is the push alternative outside MCP.

Hogswap MCP — questions

Answers built from our own checks of this server.

What can Hogswap MCP do?

It exposes 12 tools, read directly from the server on our last check. Among them: build_swap, delete_watch, get_balance, get_credit_offer, get_quote, list_payable_assets and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Hogswap MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 610 ms. The bar chart above shows every period we have measured.

How do I connect Hogswap MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Hogswap MCP need an API key?

No. Hogswap MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Hogswap MCP?

It answers our handshake in 610 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Hogswap MCP?

The npm package hogswap-mcp was installed 91 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Hogswap MCP open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
