Summary

Critical issues: Only 2 unique tools exist (get_price, get_price_price_change), but the tool list shows 7 duplicates, indicating either a registration bug or incomplete deduplication in the server. Both tools have minimal descriptions (50-60 chars, below the 194-char baseline). Parameter schemas are present but lack type constraints (no enums, ranges, or format specs). No output schema documentation. No error handling guidance. The code shows basic HTTP calls with EnsureSuccessStatusCode() but no recovery hints for LLMs. Symbol resolution (bitcoin→BTCUSDT) is undocumented, forcing LLMs to guess valid inputs.

Issues (5)

CRITICALtool ↗

Tool list shows 7 entries but only 2 unique tools (get_price appears 4x, get_price_price_change appears 3x). Indicates duplicate registration or incomplete deduplication. LLMs will see conflicting tool definitions.

get_priceget_price_price_change

HIGHconstrained-input ↗

Parameter 'symbol' lacks type constraints. Description says 'e.g. BTC, ETH, BTCUSDT' but does not document that 'bitcoin' and 'ethereum' are also valid aliases. LLMs cannot infer the symbol resolution logic (GetSymbolFromName). No enum or pattern constraint.

get_priceget_price_price_change

HIGHresponse-shaper ↗

No output schema documented. Tools return raw JSON from Binance API (e.g. {"price": "..."}). LLMs cannot plan downstream operations or extract fields reliably. Mcp.WithPrompts variant parses and formats output, but this is not documented in tool definitions.

Recommendations

Deduplicate tool registration. Ensure each tool is registered exactly once in the MCP server. Verify McpServerTool attributes are not duplicated across multiple files or methods.
Expand parameter description for 'symbol' to document valid formats and aliases: 'The trading symbol (e.g., BTCUSDT, ETHUSDT) or common name (bitcoin, ethereum). Aliases are case-insensitive and auto-converted to uppercase trading pairs.'
Document output schema in tool descriptions. E.g., 'Returns JSON with fields: price (string, USD price), symbol (string, trading pair).' Or return a formatted string like Mcp.WithPrompts does: 'The current price of BTCUSDT is $...'
Expand tool descriptions to 150 - 250 characters. Explain when to use each tool: 'Get the current spot price of a crypto asset from Binance. Use this for real-time pricing; use get_price_price_change for 24-hour trends.'
Add error handling guidance in descriptions: 'If the symbol is not found, try a common alias (bitcoin, ethereum) or a full trading pair (BTCUSDT). Invalid symbols return HTTP 400.'
