The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
etrade_cancel_orderCancel an open E*TRADE order by orderId. Requires confirm:true. An order already routed to or filled at market cannot be cancelled.
etrade_get_balanceGet cash balance, buying power, and NAV for an E*TRADE account.
etrade_get_portfolioGet current positions for an E*TRADE account.
etrade_get_transactionGet detail for a specific E*TRADE transaction.
etrade_list_accountsList all E*TRADE accounts for the authenticated user.
etrade_list_ordersList orders for an E*TRADE account (read-only). Use status=OPEN to see working orders or status=EXECUTED to confirm a fill before placing a paired stop.
etrade_list_transactionsList transactions for an E*TRADE account in a date range.
etrade_place_orderSTEP 2 — SENDS THE ORDER TO MARKET (real money in PROD). Accepts ONLY a previewId from a recent etrade_preview_order plus confirm:true. It replays the exact order that was previewed, so you can never place something that was not previewed and shown to the user first.
etrade_preview_orderSTEP 1 of placing an E*TRADE order. Validates the order and returns E*TRADE's own cost/commission estimate plus a previewId. Nothing is sent to market. Show the preview to the user, then call etrade_place_order with that previewId and confirm:true within 3 minutes to execute.
etrade_preview_spreadetrade_snapshotFan-out snapshot of all E*TRADE accounts: balances + positions (+ optional recent transactions).
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
11/11 tools missing one or more hints — etrade_cancel_order (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); etrade_get_balance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); etrade_get_portfolio (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/11 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
5/11 tools referenced in tests (45%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.11 (high), @modelcontextprotocol/sdk@1.11 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
1/4 production deps stale: oauth-1.0a@2022-06-22 (4.1y)
