Claude Code: deny. ### `delete_watch` - The name "delete_watch" says "delete": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Delete one of your watches by its client_key. ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `pay_x402_invoice` - The name "pay_x402_invoice" says "pay": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Changes things (6) Creates or changes something that can be changed back. Claude Code: ask. ### `build_swap` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `get_credit_offer` - The name "get_credit_offer" says "get": a word for reading. - The description's first verb is "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `register_agent` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `set_watch` - The name "set_watch" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `value_lp_token` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_registration` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `get_balance` - The name "get_balance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Current HOGSWAP credit balance for your API key. ``` ### `get_quote` - The name "get_quote" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `list_payable_assets` - The name "list_payable_assets" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Assets accepted as payment inputs for pay_x402_invoice and credit top-ups (price-confidence gated; ALGO and USDC always included). ``` ### `list_watches` - The name "list_watches" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `hogswap`: ```json { "permissions": { "allow": [ "mcp__hogswap__list_payable_assets", "mcp__hogswap__get_quote", "mcp__hogswap__get_balance", "mcp__hogswap__list_watches" ], "ask": [ "mcp__hogswap__build_swap", "mcp__hogswap__pay_x402_invoice", "mcp__hogswap__register_agent", "mcp__hogswap__verify_registration", "mcp__hogswap__get_credit_offer", "mcp__hogswap__value_lp_token", "mcp__hogswap__set_watch" ], "deny": [ "mcp__hogswap__delete_watch" ] } } ```
