## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (9)

### `leaderboard` (~376 tokens)

Polymarket traders ranked by realized PnL and other stats over a window, with filters. Each row is an entity (one trader, possibly several wallets).

Input parameters:

- `bands` (string): unlock price bands to include, comma-separated: 0 = free … 5
- `category` (string): market category, e.g. "politics", "sports", "crypto", "crypto-updown", "esports"
- `dir` (string)
- `limit` (number): rows, at most 200 (rows count against a daily allowance of 20,000)
- `maxWallets` (number): at most this many wallets in the entity
- `minCategoryShare` (number): with category: at least this share (0–1] of the trader's volume in it
- `minEligible` (number): floor on markets that count toward the win rate
- `minFills` (number): floor on number of fills
- `minPnl` (number): floor on realized PnL in USD
- `minRoi` (number): floor on ROI on buys (0.1 = 10%)
- `minVolume` (number): floor on traded volume in USD
- `minWinLo` (number): floor on the lower bound of the 95% win-rate interval (0–1): a win rate that is not luck
- `minWinsLosses` (number): floor on markets won or lost
- `offset` (number): rows to skip (signed-in accounts; anonymous callers see a fixed sample)
- `period` (string): statistics window: "30d" (default) or "7d"
- `sort` (string): column to sort by (default realizedPnl)
- `status` (string)
- `style` (string)

### `entity` (~53 tokens)

One trader's statistics by handle or address (full address only once unlocked).

Input parameters:

- `id` (string, required): 12-character handle or 0x address
- `period` (string): "30d" or "7d"

### `subscriptions` (~18 tokens)

The traders this account follows (active and paused subscriptions).

### `subscribe` (~76 tokens)

Follow a trader: their fills start arriving from now on. BILLS THE ACCOUNT per hour (unless the plan covers it). 402 = balance too low; 409 = no fill for 7 days (retry with acceptInactive).

Input parameters:

- `acceptInactive` (boolean)
- `entityId` (string, required): handle or 0x address

### `cancel_subscription` (~35 tokens)

Stop following (and stop paying for) a subscription, by its id from `subscriptions`.

Input parameters:

- `id` (string, required): subscription id

### `new_fills` (~103 tokens)

Fills of the followed traders since the previous call of this tool (first call: the last hour). Each fill is returned once to this server; the CLI `pmwallets new-fills` shares the position file, so do not poll with both at once (or give each its own PMW_MCP_STATE). Call again while `more` is true.

Input parameters:

- `limit` (number): at most this many fills (default 100, max 500)

### `fills` (~73 tokens)

Fills of the followed traders strictly after a ledger position (block, logIndex), oldest first. Does not move the new_fills cursor.

Input parameters:

- `limit` (number): max 500
- `sinceBlock` (number, required): block
- `sinceLogIndex` (number): log index within the block (default 0)

### `market` (~44 tokens)

The Polymarket market and outcome an outcome token id belongs to (question, outcome name, slug, end date).

Input parameters:

- `tokenId` (string, required): outcome token id (decimal)

### `account` (~19 tokens)

The account's plan (allowances used) and balance.

## Common questions

### What is the PMWallets MCP server?

PMWallets is an MCP server listed in the public MCP registry as io.github.polymarketwallets/pmwallets. Polymarket smart-money data: rank traders by on-chain PnL, follow them, read their fills. This page covers its npm package (pmwallets).

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

PMWallets scores 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 18 October 2026. It declares no install or post-install scripts. 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 PMWallets MCP server expose?

PMWallets exposes 9 tools: leaderboard, entity, subscriptions, subscribe, cancel_subscription, and 4 more. Their descriptions and schemas cost roughly 797 tokens of context every time the server is loaded.

### Is the PMWallets MCP server still maintained?

PMWallets is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the PMWallets MCP server under?

PMWallets declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
