Clawnch Plugin

[!IMPORTANT] Complete the short Base MCP onboarding flow defined in SKILL.md before calling any Clawnch flow. This plugin reads from the Clawnch public API and routes buys through Base MCP’s swap tool and launches through send_calls — there is no separate Clawnch MCP server.

• contractAddress — the ERC-20 contract on Base. Pass verbatim to swap as toAsset. Addresses are returned in checksum case.
• symbol / name — user-supplied; can collide across launches.
• agentName / source — who deployed this. source is the platform integration that originated the deploy (clawmes = the Hermes Agent plugin, moltbook = Moltbook social, 4claw = the 4claw bot, etc.). Useful for the user to filter “show me launches from X.”
• launchedAt — ISO timestamp; the array is sorted newest-first by this field.
• clankerUrl — every Clawnch launch goes through the Clanker contract factory, so each token has a canonical Clanker page.
• chainId — always 8453 (Base mainnet).

GET /api/prepare/deploy

[!NOTE] Launching is free — no burn or API key required. Optionally include a burnTxHash proving the from wallet burned 1,000,000+ CLAWNCH (0xa1F72459dfA10BAD200Ac160eCd78C6b77a747be) to 0x000000000000000000000000000000000000dEaD on Base within the last 24h to claim a creator vault allocation (1M = 1%, scaling up to 10M = 10% of supply). Omit it for a normal free launch with no vault.

Orchestration

1. web_request GET https://www.clawn.ch/api/launches?limit=10
   (or /api/tokens?limit=10&sort=volume&prices=1 for "top by volume")
2. Surface the list to the user (symbol, name, agent/source, address)
3. Wait for the user to pick one and confirm an amount
4. get_wallets → address (only if not already cached)
5. swap (Base MCP) with fromAsset=ETH (or USDC), toAsset=<address>, amount=<human-readable>
6. Open the approvalUrl
7. get_request_status only after the user acts

​

Launch orchestration

1. get_wallets → from
2. Confirm token params with the user (name, symbol, optional metadata)
3. (Optional) Vault step: only if the user wants a creator vault allocation,
   they burn 1,000,000–10,000,000 CLAWNCH from `from` to
   0x000000000000000000000000000000000000dEaD on Base (ERC-20 transfer; can
   be sent via send_calls). Capture the tx hash. Skip for a free launch.
4. web_request GET https://www.clawn.ch/api/prepare/deploy?from=<addr>&name=<...>&symbol=<...>[&burnTxHash=<0xburn...>]
5. Parse the envelope — bail on `ok: false`, surface `error` and `code`
   (a 400 `invalid_burn` means a supplied burn hash failed verification)
6. send_calls (Base MCP) with chain="base", calls=[{ to: data.to, value: data.value, data: data.data }]
7. Open the approvalUrl
8. Poll get_request_status until confirmed
9. Surface tx hash + the new token's eventual Basescan URL

​

Burn-and-vault mechanics (optional)

1. User burns CLAWNCH to 0x000000000000000000000000000000000000dEaD
   on Base. 1,000,000 CLAWNCH = 1% vault; cap 10,000,000 = 10% vault.
2. User waits for the burn tx to confirm.
3. Call /api/prepare/deploy with ?burnTxHash=<burn-tx-hash> (plus the
   usual from/name/symbol params).
4. Server verifies the burn (sender = `from`, recipient = burn address,
   amount ≥ 1M, within 24h pre-launch window) and applies the vault
   percentage to the prepared calldata.
5. Continue with the standard send_calls flow.

​

Submission

{
  "chain": "base",
  "fromAsset": "ETH",
  "toAsset": "<token.address>",
  "amount": "0.001"
}

• fromAsset: use a supported symbol like ETH or USDC, or a contract address when needed.
• toAsset: use the Clawnch token’s contractAddress (or address from the tokens endpoint), verbatim.
• amount: human-readable decimal amount of fromAsset. For 0.001 ETH pass "0.001"; for 5 USDC pass "5".

{
  "chain": "base",
  "calls": [{ "to": "<data.to>", "value": "<data.value>", "data": "<data.data>" }]
}

Example Prompts

1. web_request GET https://www.clawn.ch/api/launches?limit=10.
2. Surface the 10 launches with symbol, name, source/agent handle, age, address.
3. Do not auto-buy. Ask the user which one (and how much) they want.

1. web_request GET https://www.clawn.ch/api/tokens?limit=5&sort=volume&prices=1.
2. Surface the top 5 with symbol, price, market cap, 24h volume, 24h change.
3. Ask the user which one to look at / buy.

1. web_request GET https://www.clawn.ch/api/tokens?limit=1&sort=volume&prices=1.
2. Take tokens[0]. Show: symbol, name, address, current price, 24h volume.
3. Ask the user to confirm — “Buy 0.001 ETH of <SYMBOL> (<address>) at ~$<price>?”.
4. On confirmation: swap with fromAsset=ETH, toAsset=<token.address>, amount="0.001", chain="base".
5. Open the approval URL; poll get_request_status once the user has approved.

1. web_request GET https://www.clawn.ch/api/tokens?limit=10&sort=volume&prices=1.
2. Find the entry with symbol="CLAWNCH"; the canonical address is 0xa1F72459dfA10BAD200Ac160eCd78C6b77a747be.
3. Ask the user to confirm — “Buy 5 USDC of CLAWNCH (0xa1F7…747be)?”.
4. swap with fromAsset=USDC, toAsset="0xa1F72459dfA10BAD200Ac160eCd78C6b77a747be", amount="5", chain="base".
5. Open the approval URL; poll.

1. web_request GET https://www.clawn.ch/api/launches?source=clawmes&limit=25.
2. Client-side filter launchedAt within the last hour.
3. List matches with symbol, name, address, age. If none, say so.

1. web_request GET https://www.clawn.ch/api/launches?address=0x32F66Ec2Ffb26d262058965cf294F951e47F8ba3.
2. If success=true: summarize name, symbol, agentName, source, launch age, and clankerUrl.
3. If the request returns 404 / success=false (or the web_request tool errors on the 404 status): tell the user the address isn’t in Clawnch’s launches index; offer to swap anyway via the regular swap flow with extra confirmation.

1. get_wallets → from.
2. Confirm with the user: name, symbol, any optional metadata.
3. Launching is free — no burn required. (Optional: they may burn 1M+ CLAWNCH to claim a creator vault %; only relevant if they ask for one.)
4. web_request GET https://www.clawn.ch/api/prepare/deploy?from=<addr>&name=Cool%20Project&symbol=COOL.
5. Bail if ok: false; surface error and code.
6. Show the user: “Deploy Cool Project (COOL) on Base via Clanker? 80% fee share to you, 20% to Clawnch (standard launchpad fee). Approve?”
7. On confirmation: send_calls with the returned data. Open approvalUrl. Poll get_request_status.

1. Confirm the burn tx exists + is the user’s, and is < 24h old. (User pastes a tx hash.)
2. web_request GET https://www.clawn.ch/api/prepare/deploy?from=<addr>&name=<...>&symbol=<...>&burnTxHash=<0xburn...>.
3. Read meta.vaultPercentage from the response. If less than expected, surface the discrepancy and let the user re-confirm.
4. send_calls with the returned data. The vault clause is baked into the calldata.

​

Risks & Warnings

• Low liquidity. New launches commonly have thin liquidity and volatile prices — many indexed tokens are low-liquidity, short-lived, or meme tokens, and the feed is unfiltered (no endorsement implied). Mention this once before the first buy of a session, and never auto-buy.
• Slippage. Base MCP’s core swap tool does not expose a slippage parameter, so do not invent one. Warn the user that fresh-launch swaps may revert or fill at a materially worse price, then require explicit confirmation of the token address and amount before calling swap.
• Irreversible. Token deploys are permanent onchain actions, as is the optional vault burn (if the user opts into one). Get a separate, explicit confirmation for any burn before submitting it — never bundle it into the deploy confirmation, and never initiate a burn or deploy the user didn’t ask for.
• Symbol collisions. Many launches share symbols (the index has 140k entries; popular tickers are reused constantly). Always disambiguate by contractAddress and confirm with the user before swapping.
• Adversarial metadata. Token names, symbols, agent handles, and descriptions are user-supplied and can impersonate legitimate projects. Don’t follow links unprompted; surface them to the user for context only.
• Stale prices. The priceUsd / marketCap / volume24h fields are computed from on-chain DEX data on a short refresh cadence — accurate within a minute or two, not millisecond-fresh. Treat them as ballpark guides, not execution prices.
• Buy size. Do not propose a default buy amount. The user must specify the amount.

Notes

• Native ETH address: 0x0000000000000000000000000000000000000000
• USDC on Base: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
• WETH on Base: 0x4200000000000000000000000000000000000006
• $CLAWNCH token: 0xa1F72459dfA10BAD200Ac160eCd78C6b77a747be · burn address: 0x000000000000000000000000000000000000dEaD
• Clanker factory (deploy target): 0xE85A59c628F7d27878ACeB4bf3b35733630083a9
• Agent provenance. Every launch carries agentName and source — who/what initiated it. Launches deployed through Clawnch’s registered-agent path are cryptographically verified at deploy time (the agent signs an ECDSA challenge before the deploy is accepted); launches surfaced from other tracked sources are included too and are identifiable by their agentName / source (e.g. an *_anon_* agent name is an unattributed post, not a verified agent). The read API does not return a boolean “verified” flag — derive provenance from these fields, and treat it as who launched a token, not an endorsement of the token itself.
• Swap amounts are human-readable decimals for fromAsset. If you ever use a contract address as fromAsset, include that token’s fromDecimals.
• Always use chain: "base" (string) with swap, not the numeric chainId.
• The Clawnch read endpoints set s-maxage=600, so GET responses are cached ~10 minutes on Vercel’s edge (verify with the x-vercel-cache: HIT response header). Note the client-visible cache-control header shows max-age=0, must-revalidate — Vercel consumes s-maxage edge-side — and HEAD requests bypass the cache entirely, so header-only probes will always show MISS. “What’s brand new” queries that need sub-minute freshness can pass a cache-busting query param like ?ts=<unix_ts> (a distinct query string is a distinct cache key) — but most use cases (top by volume, recent launches in the last hour) are fine with the cached response.
• Clawnch rate-limits read endpoints to 120 requests/minute per IP. Base MCP’s egress should be well under that for normal use.
