Trading tools for AI agents: token risk checks, swap quotes, unsigned swaps, holdings on 5 chains.
Remote MCP server giving assistants token prices, risk checks, swap quotes and unsigned swaps across five chains, plus stock tokens, perps and wallet holdings.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.fivebar-xyz%2Ffivebar/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Skills that teach AI agents to work with live data and act on it safely, through the Fivebar MCP. Every answer shows its sources.
The routine a careful trader follows, as one tool call per step:
token_risk before every buy. Honeypots, mint and freeze authorities, taxes, owners, thin liquidity.swap_quote with the minimum out and every fee shown, before anything is built.swap_build returns unsigned transactions. Exact-amount approvals only. Your own wallet signs.wallet_holdings after the swap, valued at what selling would get now. Airdrops nobody can sell are flagged, not counted.Was the launch clean? Safety, who bought in the first minute and whether they're linked, what the dev did since, who holds it now: four checks, run side by side. Then follow a wallet's money, read what it did today with fake lookalike tokens flagged, and check an x402 seller before paying. Facts, not accusations: wallets are never named.
Due diligence the way an analyst does it: growth and margins from the 10-K and 10-Q, insiders' open-market buys and sales (routine pay and 10b5-1 plans told apart), dilution (share growth first, then shelves, ATMs and warrants; splits never counted), the filing's own words, and a fund's 13F holdings. Every number comes with its filing and date.
Instructions only. No scripts, nothing runs on your machine, no keys ever asked for or handled. Each skill reads in a minute.
Claude Code: the plugin installs the skill and connects the Fivebar MCP in one go.
Codex, Cursor, GitHub Copilot, Gemini CLI and other agents that read Agent Skills:
From a script or another agent (no prompts, every agent on the machine):
Then connect the MCP if your agent doesn't have it yet: add https://fivebar.xyz/mcp as a remote (Streamable HTTP) MCP server. Free, no key.
Any agent: the MCP sends a short version of these routines when it connects, and offers seven prompts: "Trade a token safely", "Is this token safe?", "What do I hold?", "Was this launch clean?", "Due diligence on a company", "Check a seller before paying" and "Watch a wallet".
Data tools are free. Wallet watchlists are a paid feature for agents: $5 for 10 wallets or $20 for 50, per 30 days, over x402. Swaps built through Fivebar carry a 0.5% fee, paid inside the swap and shown in every quote next to the router's fee and gas.

Robinhood stock tokens
List the tokenized stocks Robinhood issues on Robinhood Chain (about 100: AAPL, TSLA, NVDA...): symbol, name, token address, shares-per-token multiplier, which trading sessions they trade in, and whether a Chainlink price feed exists. Filter with query (symbol or name).
limitqueryStock token price
Price of a Robinhood stock token on Robinhood Chain, by symbol (e.g. AAPL) or token address: the Chainlink feed price per token (dividends and splits included through the multiplier), how fresh it is, the on-chain DEX price where a Uniswap pool exists, and which sessions it trades in. Equity feeds follow US market hours 24/5 and hold their last price when markets are closed.
symbolrequiredToken price (memecoins and any ERC-20)
Price and market cap of any token by its contract address. A 0x address is read on Robinhood Chain by default (Uniswap v3 and v4 pools; when the best pool is thin, under $2,000 in range, or missing, the price comes from a $10 buy routed by 0x and a warning says so); pass chain base, ethereum or arbitrum for those chains. A Solana mint is priced from a small USDC buy routed across Solana DEXes.
chainaddressrequiredSwap quote (best route, fees shown)
What swapping one token for another would give right now, on Robinhood Chain (default), Solana (SOL, USDC, USDT and memecoins by mint address; picked automatically for those), Base, Ethereum or Arbitrum (ETH, WETH, USDC, USDT or a token address; pass chain). EVM chains: the best route across Uniswap v2/v3/v4, PancakeSwap, SushiSwap, Aerodrome, Curve and other DEXes. Solana: the best route across Solana DEXes. Routed by 0x, with the amount out and the minimum after slippage, the USD value, and every fee shown separately (Fivebar's 0.5%, the router's fee where it applies, and network gas). Flags token taxes and, if you pass your wallet as taker, a missing balance or approval. xStocks are coming soon: use stock_quote for their prices. Quote only: nothing is signed or sent; to swap, use swap_build.
buyrequiredsellrequiredchaintakeramountrequiredslippage_pctToken risk check (before you buy)
What could go wrong buying a token, by contract address, on Solana, Robinhood Chain, Base, Ethereum or Arbitrum. Solana: whether someone can still mint more or freeze holders, Token-2022 traps (transfer fees, a permanent delegate, transfer hooks), and how concentrated the top holders are. EVM: buy and sell taxes and whether the contract still has an owner. Both: a $100 buy-then-sell test through the router (can you sell it, and what's lost). Returns a verdict (high, caution or low) and the reasons. Not a guarantee.
chainaddressrequiredSwap: build the transactions to sign
Build a swap for your own wallet to sign and send, on Robinhood Chain, Base, Ethereum, Arbitrum or Solana. Returns a firm quote (amount out, minimum, every fee) and the unsigned transactions in order. EVM chains: an exact-amount approval when needed, then the swap. Solana: one versioned transaction (base64) your wallet pays for and signs. Fivebar's 0.5% fee is paid inside the swap; Fivebar never sees your keys or holds your funds. Wallets on the US sanctions list are refused. xStocks are coming soon.
buyrequiredsellrequiredchaintakerrequiredamountrequiredslippage_pctETH price
ETH price in USD on Robinhood Chain (Chainlink feed, or the deepest WETH/USDG pool if the feed is unavailable).
Takes no parameters.
Wallet holdings (every token, 5 chains)
Every token a wallet holds, with USD values, across Robinhood Chain, Base, Arbitrum and Ethereum for a 0x address (or one chain with chain), or on Solana for a Solana address. Includes ETH or SOL, stablecoins, Robinhood stock tokens and memecoins. Values: $1 for stablecoins, the ETH price for ETH and WETH, Chainlink for stock tokens, Uniswap pools on Robinhood Chain (a router buy when the pool is thin), a small buy routed by 0x elsewhere. The biggest positions carry a quick risk verdict (run token_risk for the full check). Tokens that look like airdropped spam are hidden and counted; tokens with no route to sell are listed apart. If the router is busy, a holding is valued from its last good quote (at most 15 minutes old) and marked priceAsOf.
chainaddressrequiredPerpetual futures (Hyperliquid)
Perpetual futures markets on Hyperliquid: mark price, 24h change, funding (hourly and yearly), open interest, 24h volume and max leverage. Sort by volume, open interest or funding; filter by coin.
sortlimitqueryOne perp market (Hyperliquid)
One Hyperliquid perpetual market by coin (e.g. BTC, ETH, HYPE): mark and oracle price, 24h change, funding, open interest, volume and max leverage.
coinrequiredx402 payments on Robinhood Chain
Fivebar's index of x402 payments (USDG transferWithAuthorization) on Robinhood Chain: the last 24 hours and recent days, screened before they count. Volume that doesn't pass is split two ways: flaggedUsd shows a wash pattern (a seller paying itself, circular payments, two wallets paying 90%+ of a seller); tooFewBuyersUsd only went to sellers with under 10 distinct buyers, which isn't evidence of washing, just not enough to judge yet. topSellers lists sellers that passed. Updated every 3 hours.
Takes no parameters.
Agent record (Fivebar board)
Look up an AI agent on Robinhood Chain by ERC-8004 agent ID, wallet address or name: its owner and agent wallet, Fivebar Score (as a seller: how many independent operators pay it, with bundled buyer wallets counted once; as a buyer: how many real sellers it pays; 'not scored yet' with progress when the evidence is thin, never a 0), screened x402 record (passed, not counted yet, removed for wash patterns), flags and clusters. Use before paying or trusting an agent.
queryrequiredCheck a seller before paying
Before paying an x402 seller on Robinhood Chain, check its address against Fivebar's wash screen: whether it's among the sellers whose payments passed in the last 24 hours, its buyers and volume, and its agent record if it's a registered agent.
addressrequired100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
