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.
get_market_overviewget_strategiesget_positionsReturns all open positions. Each has: symbol, detected strategy type, legs (strike/expiry/qty), entry price, current value, P&L ($, %), DTE.
execute_tradeclose_positionReturns instructions to close a position (does NOT auto-execute). Shows inverse legs and recommended price. You must then call execute_trade() yourself.
adjust_orderAdjust a working order's price to improve fill. 'improve_fill' moves price by one tick toward fill (credit→cheaper, debit→pricier). 'custom' sets exact price. Requires ENABLE_LIVE_TRADING=true.
get_working_ordersget_account_infoReturns account balance: cash, net liquidating value, options buying power, stock buying power. Check before trading.
get_connection_statusCheck if TastyTrade is connected, streamer is active, and market status (open/closed). Call first to verify server is operational.
get_watchlistsReturns personal + platform watchlists. Use names as input to get_market_overview(watchlist='...'). Manage with manage_watchlist().
manage_watchlistManage personal watchlists. Actions: create (new list), add (symbols to list), remove (symbols from list), delete (entire list).
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 — get_market_overview (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_strategies (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_positions (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 4/11 tool handlers declare input schemas (36%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
10/11 tool handlers wrap calls in try/catch (91%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
