## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 82/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1242 tokens (~82/item across 15 items; 15 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 80/100
  - Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 15 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 15 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (15)

### `error_catalog` (~27 tokens)

Machine-readable catalog of every error code the Epsilon API returns, with meanings and retry guidance.

### `get_example` (~50 tokens)

Input parameters:

- `id` (string, required): example id from list_examples, e.g. python-dca-cron

### `get_market_overview` (~53 tokens)

One-call market snapshot of Epsilon (Robinhood Chain DEX): top tokens by 30-day volume, 24h volume aggregates, and engine-wide order/fill stats. Good first call for market context.

### `get_order_status` (~58 tokens)

Look up an Epsilon order by hash: status (pending/active/filled/cancelled), parameters, and its fills.

Input parameters:

### `get_quote` (~125 tokens)

Best executable quote for swapping tokenIn → tokenOut on Epsilon (Robinhood Chain, id 4663). Amounts are RAW token units — scale by the token's decimals first. This only quotes; it never executes.

Input parameters:

- `amountIn` (string, required): amount of tokenIn in RAW token units (decimal string, already scaled by the token's decimals)
- `tokenIn` (string, required): ERC-20 address of the token being sold (0x-hex)
- `tokenOut` (string, required): ERC-20 address of the token being bought (0x-hex)

### `get_route` (~240 tokens)

Full routing breakdown for a swap: best venue split, expected and minimum output, price impact (ppm), and the feeLegs a signed order must embed. Read-only. Amounts are RAW token units.

Input parameters:

- `amountIn` (string, required): amount of tokenIn in RAW token units (decimal string, already scaled by the token's decimals)
- `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
- `slippageBps` (integer): slippage tolerance in basis points (default 100 = 1%)
- `tokenIn` (string, required): ERC-20 address of the token being sold (0x-hex)
- `tokenOut` (string, required): ERC-20 address of the token being bought (0x-hex)

- `wallet` (string): optional maker wallet address — include it to get the exact feeLegs an order for this wallet must embed

### `list_examples` (~46 tokens)

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_orders` (~104 tokens)

List Epsilon orders by maker wallet, status, and/or type — the portfolio view. Newest first.

Input parameters:

- `limit` (integer): max rows (default 100, cap 500)
- `status` (string): order status filter, e.g. active, filled, cancelled
- `type` (string): order type filter, e.g. limit, dca, trailing
- `wallet` (string): maker wallet address to filter by (0x-hex)

### `market_stats` (~26 tokens)

Engine-wide Epsilon stats: order counts by status, fill counts, and volume aggregates.

### `order_preflight` (~118 tokens)

Check whether a limit/DCA order for this pair and size would be executable: oracle support, liquidity, minimum size. Run this before signing an order. Amounts are RAW token units.

Input parameters:

- `amountIn` (string, required): amount of tokenIn in RAW token units (decimal string, already scaled by the token's decimals)
- `tokenIn` (string, required): ERC-20 address of the token being sold (0x-hex)
- `tokenOut` (string, required): ERC-20 address of the token being bought (0x-hex)

### `recent_swaps` (~60 tokens)

Most recent swaps executed through Epsilon, optionally filtered to one wallet. Amounts are RAW token units.

Input parameters:

- `limit` (integer): max rows (default 100, cap 500)
- `wallet` (string): optional wallet address to filter by

### `search_docs` (~98 tokens)

Search the Epsilon developer documentation (API, auth, order signing, webhooks, rev-share, SDKs, MCP). Returns the most relevant doc sections. No API key required.

Input parameters:

- `limit` (integer): max sections to return (default 5, cap 10)
- `query` (string, required): what to look for in the Epsilon developer docs, e.g. 'sign an order', 'rate limits', 'webhooks signature'

### `search_tokens` (~106 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.

Input parameters:

- `limit` (integer): max rows (default 20, cap 100)
- `search` (string): symbol or name fragment (e.g. USDG), or an exact 0x address; empty returns the top tokens by 30-day volume

### `token_volume` (~65 tokens)

Per-token and total swap volume over a window (1h, 24h, 7d, 30d, all).

Input parameters:

- `window` (string): aggregation window: 1h, 24h (default), 7d, 30d, or all

## Common questions

### What is the Epsilon MCP server?

Epsilon is an MCP server listed in the public MCP registry as io.github.alienbase-xyz/epsilon. Non-custodial limit, stop-loss and DCA trading on Epsilon (Robinhood Chain) for AI agents. This page covers its hosted endpoint (https://api.epsilon.exchange/mcp).

### Is the Epsilon MCP server safe to use?

Epsilon scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Epsilon MCP server expose?

Epsilon exposes 15 tools: error_catalog, get_example, get_market_overview, get_order_status, get_orderbook, and 10 more. Their descriptions and schemas cost roughly 1,242 tokens of context every time the server is loaded.

### Does the Epsilon MCP server require authentication?

No. We connected to Epsilon without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Epsilon MCP server still maintained?

Epsilon is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
