X-API-Key (required)

Epsilon developer key (eps_…) — create one at developers.epsilon.exchange

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

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.

orderHashstring, required

EIP-712 order hash to cancel (0x-hex, 32 bytes) — from list_orders

notestring

optional reason shown to the user (≤ 140 chars)

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

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.

read-only

Argument	Type	Description
tokenIn*	string	ERC-20 address of the token being sold (0x-hex)
amountIn*	string	amount of tokenIn in RAW token units (decimal string, already scaled by the token's decimals)

    }
  },
  "additionalProperties": false

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.

read-only

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.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",
  "additionalProperties": false

  },
  "additionalProperties": false
}

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 immediately or need an approval link. Grants are created and revoked by the user in the Epsilon app, never by a tool.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",

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 returns per-token and total swap volume over window. For one token use search_tokens; for executed trades use list_fills.

read-only

Argument	Type	Description
scope	string	what to return: overview (default — top tokens by 30d volume + 24h volume + engine stats, the best first call), engine (order counts by status, fill counts, volume aggregates), or volume (per-token and total swap volume over window)
window	string	for scope=volume: 1h, 24h (default), 7d, 30d, or all

    }
  },
  "additionalProperties": false
}

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 the keyless /mcp endpoint it explains how to sign in instead.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",
  "additionalProperties": false
}

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.

read-only

Argument	Type	Description
orderHash*	string	EIP-712 order hash (0x-hex, 32 bytes)

      "description": "EIP-712 order hash (0x-hex, 32 bytes)"
    }
  },
  "additionalProperties": false
}

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.

read-only

Argument	Type	Description
tokenA*	string	first token address of the pair (0x-hex)
tokenB*	string	second token address of the pair (0x-hex)

    }
  },
  "additionalProperties": false
}

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 token's decimals first. Never executes.

read-only

Argument	Type	Description
tokenIn*	string	ERC-20 address of the token being sold (0x-hex)
amountIn*	string	amount of tokenIn in RAW token units (decimal string, already scaled by the token's decimals)

      "description": "ERC-20 address of the token being bought (0x-hex)"
    }
  },
  "additionalProperties": false
}

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 would be executable at all. Read-only. Amounts are RAW token units.

read-only

Argument	Type	Description
wallet	string	optional maker wallet address — include it to get the exact feeLegs an order for this wallet must embed
tokenIn*	string	ERC-20 address of the token being sold (0x-hex)

tokenOut*	string	ERC-20 address of the token being bought (0x-hex)
orderType	string	order kind being priced (limit \| stop_loss \| take_profit \| dca \| trailing) — selects the fee cell served in feeLegs; omit for a direct swap

    }
  },
  "additionalProperties": false

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.

read-only

Argument	Type	Description

limit	integer	max rows (default 100, cap 500)
status	string	order status filter, e.g. active, filled, cancelled

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 agent grant. HUMAN units; amount is the TOTAL.

Argument	Type	Description
note	string	optional one-line reason shown to the user (≤ 140 chars)
every*	string	interval between sells like 15m, 1h, 1d (minimum 1m)
amount*	string	TOTAL amount of tokenIn across the whole program, HUMAN units, decimal string
tokenIn*	string	ERC-20 address being sold in slices (0x-hex)
tokenOut*	string	ERC-20 address being accumulated (0x-hex)
executions*	integer	number of sells, 2–500; each sells amount/executions
slippageBps	integer	slippage tolerance per execution in basis points (default 100)
triggerPrice	string

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 (status reserved or submitted); otherwise you get an approval link the user signs in the Epsilon app (status needs_approval). Run check_order first. For a protective sell below the market use place_stop_order; for an immediate swap use place_market_order. HUMAN units.

Argument	Type	Description
note	string	optional one-line reason shown to the user (≤ 140 chars)
amount*	string	amount of tokenIn in HUMAN units, decimal string
tokenIn*	string	ERC-20 address being sold (0x-hex)
tokenOut*	string	ERC-20 address being bought (0x-hex)
expiresIn	string	optional lifetime like 7d, 24h, 30m; default: never
requestId	string	stable 32 lowercase hex characters for this trade; required for autonomous execution, reuse unchanged when retrying
limitPrice*	string	price in tokenOut per 1 tokenIn, decimal string (e.g. selling WETH for USDG at "4200")

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 are HUMAN units.

Argument	Type	Description
note	string	optional one-line reason shown to the user on the approval page (≤ 140 chars)
amount*	string	amount of tokenIn in HUMAN units, decimal string (e.g. "50" USDG, "0.25" WETH) — not raw units
tokenIn*	string	ERC-20 address being sold (0x-hex); resolve symbols with search_tokens first
tokenOut*	string	ERC-20 address being bought (0x-hex)
slippageBps	integer	slippage tolerance in basis points (default 100 = 1%, max 5000)

  },
  "additionalProperties": false
}

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); this tool is for protection BELOW it. Autonomous stops enforce a signed minimum and may remain unfilled after a price gap. HUMAN units.

Argument	Type	Description
note	string	optional one-line reason shown to the user (≤ 140 chars)
amount*	string	amount of tokenIn to sell, HUMAN units, decimal string
tokenIn*	string	ERC-20 address being sold when the stop triggers (0x-hex)
tokenOut*	string	ERC-20 address received (0x-hex), usually USDG
requestId	string	stable 32 lowercase hex characters for this trade; required for autonomous execution, reuse unchanged when retrying
slippageBps	integer	slippage tolerance for the fill in basis points (default 100)
triggerPrice*	string	stop trigger in tokenOut per 1 tokenIn, decimal string — strict floor stop order; may remain unfilled if the price gaps below its minimum

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_order. HUMAN units.

Argument	Type	Description
note	string	optional one-line reason shown to the user (≤ 140 chars)
amount*	string	amount of tokenIn to sell, HUMAN units, decimal string
tokenIn*	string	ERC-20 address being protected / sold when the trail triggers (0x-hex)
tokenOut*	string	ERC-20 address received (0x-hex), usually USDG
expiresIn	string	optional lifetime like 7d, 30d; default 7d
slippageBps	integer	slippage tolerance for the fill in basis points (default 100)
trailPercent*	number	distance below the running high that triggers the sell, in percent (e.g. 5 = 5%); 0.1–99
