This server has 10 tools with explicit schemas and descriptions, but quality is inconsistent. Tool naming generally follows verb patterns (search, create, research, update, fetch, coingecko-*, defillama-*), meeting basic standards. However, descriptions are terse (averaging ~50-80 chars, well below the 194-char production baseline), parameter descriptions are sparse or missing entirely, and output schemas are not documented. The server shows READ_ONLY and WRITE risk classifications, indicating awareness of state-changing operations, but error handling and recovery guidance are absent from tool definitions. Per-tool analysis reveals 4 tools with minimal description quality, 6 tools with incomplete parameter documentation, and zero tools with documented output structures. This is typical of a functioning but immature MCP server that prioritizes core functionality over LLM-optimized interface design.

Descriptions are uniformly terse (35-55 chars). Production baseline is 194 chars. Critical tool selection context is missing. Examples: 'Search query' for search tool, 'Update the status of a research section' for update-status. LLMs cannot infer WHEN or WHY to call these tools without richer context (what happens? what returns? what prerequisites?).
Parameter descriptions are generic or absent. 'query' param appears in search, coingecko-search, defillama-search but lacks guidance on format, length constraints, or what makes a good query. 'tokenName' and 'tokenTicker' params lack distinguishing context (is ticker optional? does it need to be uppercase?). No guidance on when to use name vs ticker vs both.
Expand tool descriptions to 150-250 chars each. Include: (1) What the tool does, (2) When to use it instead of similar tools, (3) What it returns, (4) Any prerequisites. Example: 'search' → 'Search the web for information. Returns snippets and links from web, news, image, or video sources. Use this before calling research-with-keywords if you don't know which keywords to target. Set searchType to specify the source (web|news|images|videos, default: web).'
Add explicit parameter descriptions for all 'query', 'tokenName', 'tokenTicker' fields. Example: 'query: A search term (2-100 chars). Can be a token name (Bitcoin), symbol (BTC), or protocol name (Uniswap). Fuzzy matching is applied; exact matches are preferred.' Example: 'tokenTicker: Stock-style symbol in uppercase (e.g., BTC, ETH). Must match coingecko-search results exactly or lookup will fail.'
Document output schemas for every tool. Provide examples showing field names, types, and availability. For coingecko-summary, document that it returns {name, symbol, market_cap_rank, current_price, market_cap, 24h_change, ...}. For search, document {results: [{title, url, snippet}], total_results}.
Add error handling guidance to CoinGecko/DeFiLlama tools. Examples: '(429) Rate limited, CoinGecko free tier allows ~30 req/min. Wait 60 seconds and retry.' '(timeout) Request took >15s. Try a simpler query (shorter token name) or use coingecko-search as a lighter alternative.'
Add 'When to retry' and 'When to ask the user' guidance to all error scenarios. Retryable: rate limits, timeouts. User-fixable: token not found (suggest search first). Fatal: malformed query.
Output schemas are not documented in any tool. LLMs do not know what fields to expect in responses, preventing them from planning downstream calls or extracting required data. Source code shows rich responses (e.g., coinGeckoTool.ts with CoinGeckoCoinDetail, CoinGeckoSearchResponse interfaces) but these are not reflected in tool definitions.
Error handling and recovery guidance are completely absent from tool definitions. Code shows sophisticated timeout handling (15-second CoinGecko timeout, AbortController) and rate-limit detection (429 response), but these are invisible to LLMs. Tools may fail silently or with generic errors, leaving agents unable to recover. No guidance like 'If rate limited, wait 60s and retry' or 'If timeout, try a simpler query'.
create-research-plan and update-status are marked WRITE operations but lack confirmation or dry-run patterns. An LLM could accidentally overwrite a research plan or corrupt status state without a safety gate. No guidance on idempotency or undo mechanisms.
fetch-content accepts a 'format' enum (text, html, markdown, json) but the description does not explain when to use each format or what the output looks like. An LLM cannot reason about which format suits its downstream needs.
coingecko-tickers has a 'limit' parameter (default 10) but no constraint documentation (min/max, why 10 as default, when to increase). An LLM might pass limit=1000 thinking more data is better, hitting rate limits or timeouts.
coingecko-tickers
For create-research-plan and update-status (WRITE ops), add a 'dry-run' parameter (boolean, default false) or reference a companion 'confirm_research_plan_creation' tool. This prevents accidental overwrites.
Expand fetch-content format parameter description: 'Output format: text (plaintext, fastest), markdown (formatted, good for readability), html (raw structure, for parsing), json (if source provides structured data). Choose markdown for chat, json for downstream parsing.'
Add numeric constraints to coingecko-tickers limit: 'Maximum number of tickers to return (1-250, default 10). Higher values increase response time; recommended max 50.'
Group related tools (coingecko-*, defillama-*) and document their interaction. Example: 'Use coingecko-search to discover a token ID, then coingecko-summary for detailed data, then coingecko-tickers for exchange listings.' This helps LLMs compose tools correctly.
Add 'Prerequisites' notes where applicable. Example for update-status: 'You must call create-research-plan first to initialize a research session, or update-status will fail with 'research context not found'.'
Document pagination/limits for tools returning many results. If search, coingecko-tickers, or defillama results are capped, state it: 'Results are limited to 20 matches. Use fetch-content to explore detailed results.'
Add 'Ambiguity handling' notes for search/coingecko-search/defillama-search. Example: 'If multiple coins match (e.g., 'Shiba' could be Shiba Inu or Shiba Predator), the tool returns the highest-ranked match by market cap. Use coingecko-search first to disambiguate if unsure.'
