All limitations / Review context

What wallet, order, and approval safeguards are currently documented?

The bounded official-source review notes that the server can hold a wallet key and place real orders; this review does not certify installation safety, so those high-impact capabilities remain an explicit uncertainty while no separate public-tracking blocker was found.

Unlike analysis-only finance MCPs, full mode can move money through real prediction-market orders.
Wallet/account authority and configured safety limits.
Polygon wallet/private key for trading.
Market/account data is fetched remotely; private key is highly sensitive.
Reviewed write actions: Place trades; Cancel/manage orders; Manage positions
Sensitive access: Wallet private key, Trading account/positions
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
The repository documents wallet-key and real-order capabilities; no independent review of authorization, custody, or trading safeguards was performed.
No independent runtime, installation, or comprehensive security audit was performed.
No installation, runtime, client matrix, or complete tool-contract audit was performed in this review.
Live trading requires a Polygon wallet/private key and USDC.

Warning

Trading is financially consequential; demo is the only safe quickstart in MCP100.
Do not copy curl-pipe-shell one-liners as unattended install.
Exact vendor-specific credential revoke procedure not established from checked official Setup documentation; may be external or not applicable. Do not invent.
Requires review of install side effects, credentials, remote scripts, or privileged application/database access before execution. Multiple publisher-documented README steps combined as an ordered excerpt; not a verbatim single publisher code block.
Full mode uses wallet credentials and may trade.
Dashboard launch itself is not a check and must not be auto-run.
Review wallet keys and transaction approvals before retiring production installations; do not delete wallets or positions as part of ordinary MCP cleanup.

What setup and authentication are documented?

Recorded installation/entrypoint step: pip install polymarket-mcp. Recorded transport: stdio. Recorded environment-variable notes: DEMO_MODE; POLYGON_PRIVATE_KEY; POLYGON_ADDRESS. No configuration values are supplied here. Prerequisites: Python 3.10+. These are the documented setup details, not a claim that installation or client compatibility was independently tested. Authentication: Wallet/private-key auth for full trading; demo mode keyless. A demo or keyless description is not independently verified read-only authority. Confirm that live order execution is disabled in the configuration you actually run before research-only use.

Can it modify data or perform write operations?

Documented write actions include: Place trades; Cancel/manage orders; Manage positions. Recorded permission boundary: Wallet/account authority and configured safety limits.

What data-handling boundary should I consider?

Market/account data is fetched remotely; private key is highly sensitive. Recorded sensitive-access context: Wallet private key; Trading account/positions.

What limitations and risks should I check before use?

Unlike analysis-only finance MCPs, full mode can move money through real prediction-market orders. Live trading requires a Polygon wallet/private key and USDC. The record describes a demo mode for research-only use; this label does not establish that live orders are disabled. The repository documents wallet-key and real-order capabilities; no independent review of authorization, custody, or trading safeguards was performed. No independent runtime, installation, or comprehensive security audit was performed.
