Tools

22 tools listed at last check
  • cancel_order Ask the user to approve cancelling one of their open orders (hash from list_orders). Returns an approval link; the cancellation is signed by the user's wallet in the Epsilon app. Orders already filled cannot be cancelled.
  • check_order Check whether a resting order (limit, stop, DCA, trailing) for this pair and size would be executable: oracle support, liquidity, minimum size. Run this before signing any resting order; it does not price the trade — get_route does. Amounts are RAW token units.
  • get_approval Status of an approval you created: pending (user hasn't decided), submitted (with orderHash or txHash — then use get_order to follow fills), rejected, failed, or expired (links live 30 minutes). Poll no more than every few seconds.
  • get_error_catalog Machine-readable catalog of every error code the Epsilon API returns, with meanings and retry guidance. Consult it when any other tool returns an error code you need to interpret or decide whether to retry.
  • get_example Full source code of one Epsilon integration example, by id from list_examples. No API key required.
  • get_grant The signed-in account's agent grant for this channel, if any: the embedded wallet it signs with, per-order and daily caps, what remains today, allowed order kinds, and whether the Epsilon signer is actually granted on the wallet. Call it before placing to know whether an order will be placed immedia
  • get_market_stats Market-level numbers for Epsilon (Robinhood Chain DEX). scope=overview (default) is the best first call: top tokens by 30-day volume, 24h volume, and engine-wide order/fill stats in one response. scope=engine returns only order counts by status, fill counts and volume aggregates; scope=volume return
  • get_me The signed-in Epsilon account behind this session: account id, handle, linked wallets (embedded first), the scopes this client was granted, and which client is connected. Call it first after sign-in to learn the wallet address other tools need. Requires an OAuth session (connect to /mcp/account); on
  • get_order One Epsilon order by hash: status (pending/active/filled/cancelled/expired), parameters, and its fills. Use list_orders to find orders by wallet first; use get_orderbook for the market's resting orders on a pair.
  • get_orderbook The market's open (pending/active) limit orders on both sides of a token pair, largest first — liquidity you can rest against. For one wallet's own orders use list_orders instead.
  • get_quote Best executable quote for swapping tokenIn → tokenOut on Epsilon (Robinhood Chain, id 4663): expected output and price. Use this for a quick price check; use get_route when you need the venue split, fee legs or minimum output for an order you will sign. Amounts are RAW token units — scale by the tok
  • get_route Full routing breakdown for a swap: best venue split, expected and minimum output, price impact (ppm), and the feeLegs a signed order must embed (pass orderType for a resting order so the right fee cell is served). Use get_quote for a plain price; use check_order to learn whether a resting order woul
  • list_examples List runnable Epsilon integration examples (Python cron DCA, LangChain tools, Vercel AI SDK tools, Telegram bot). Fetch full source with get_example. No API key required.
  • list_fills Executed trades (swaps and order fills) on Epsilon, newest first, optionally for one wallet — the trade history. For resting/open orders use list_orders. Amounts are RAW token units.
  • list_orders A wallet's Epsilon orders filtered by status and/or type — the portfolio view, newest first. Use get_order for one order's fills; use list_fills for executed trades.
  • place_dca_order Ask the user to approve a DCA program: sell amount of tokenIn for tokenOut in `executions` equal slices, one every `every` (15m, 1h, 1d…). Optionally gated by triggerPrice (only sells at or below it). Keeper-executed after signing; always returns an approval link — DCA is never executed under an age
  • place_limit_order Place a resting limit order: sell amount tokenIn for tokenOut once the market reaches limitPrice (tokenOut per tokenIn) or better. Keeper-executed — it keeps working with the chat closed. If the user granted this client an agent grant and the order fits its caps, it is queued with a stable requestId
  • place_market_order Ask the user to approve a market swap of amount tokenIn → tokenOut at the best current route. Returns an approval link, not a fill: the user signs in the Epsilon app. Use get_quote first to tell the user what to expect. For a price-conditional order use place_limit_order or place_stop_order. Amounts
  • place_stop_order Place a stop-loss: sell amount tokenIn for tokenOut if the price falls to triggerPrice (tokenOut per tokenIn). Keeper-executed. Queued under an active agent grant that covers it, otherwise returns an approval link (status needs_approval). Use place_limit_order to sell ABOVE the market (take profit);
  • place_trailing_order Ask the user to approve a trailing stop: sell amount tokenIn for tokenOut when price drops trailPercent below its running high since placement. Keeper-executed after signing; always returns an approval link — trailing stops are never executed under an agent grant. For a fixed level use place_stop_or
  • search_docs Search the Epsilon developer documentation (API, auth, order signing, webhooks, rev-share, SDKs, MCP). Returns the most relevant doc sections. No API key required.
  • search_tokens Resolve a token symbol or name to its address and decimals — call this FIRST when the user names a token; every other tool takes addresses. volume30dUsd disambiguates same-symbol tokens: the real one has volume.
