## 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 2026-09-25.

- **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**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1409 tokens (~93/item across 15 items; 11 tools + 4 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `quote_order` (~206 tokens)

Quote an order (fee-inclusive)

Preview an order against the live book without placing it: average and worst price, shares, cost, payout if the outcome wins, Polymarket fee, predictDEX fee and warnings. Market BUY amount is USD to spend all-in; market SELL and limit amounts are shares.

Input parameters:

- `type` (string): market (default) or limit

### `get_trading_setup` (~68 tokens)

How to trade through predictDEX

Everything an agent with its own wallet needs to trade: chain, collateral (pUSD), builder code, signer URL, attestation steps, fees and a ready-to-run TypeScript snippet using Polymarket's official SDK. Non-custodial: you sign with your own key.

### `create_trade_link` (~132 tokens)

Create a trade link for a person

A pre-filled predictDEX ticket URL (event, market, outcome, side, amount) for a person to review and sign in their own wallet. Opening it executes nothing. Use this when you have no wallet or need human confirmation.

Input parameters:

- `amount` (number): USD to spend for BUY, shares for SELL
- `market` (string): Market id or conditionId (defaults to the event's main market)
- `outcome` (string): 0 = first outcome (Yes), 1 = second (No)
- `side` (string): BUY or SELL

### `attest_agent` (~91 tokens)

Attest as an agent (get a token)

- `message` (string, required): The exact challenge message
- `signature` (string, required): 0x EIP-191 signature

## Common questions

### What is the predictDEX MCP server?

predictDEX is an MCP server listed in the public MCP registry as mk.dex/predictdex. Live Polymarket odds, order books, fee-inclusive quotes and non-custodial prediction trading. This page covers its hosted endpoint (https://predict.dex.mk/mcp).

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

predictDEX scores 76 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 predictDEX MCP server expose?

predictDEX exposes 11 tools: search_markets, get_event, get_orderbook, get_price_history, quote_order, and 6 more. Their descriptions and schemas cost roughly 1,036 tokens of context every time the server is loaded.

### Does the predictDEX MCP server require authentication?

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

### Is the predictDEX MCP server still maintained?

predictDEX is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
