Top Gainers (Alpha-Ranked): Today's biggest 24h gainers across the CoinGecko top-1000 universe (stablecoins and wrapped BTC/ETH derivatives filtered out) plus per-chain ecosystem gainers for Ethereum, Base, Arbitrum, BNB Chain, Polygon, and Optimism — RANKED BY CROSS-SIGNAL ALPHA CONFLUENCE, not ...

AI agents call top_gainers_comprehensive to retrieve information from Agent Einstein — Autonomous Crypto Intelligence without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though top_gainers_comprehensive only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Top Gainers (Alpha-Ranked): Today's biggest 24h gainers across the CoinGecko top-1000 universe (stablecoins and wrapped BTC/ETH derivatives filtered out) plus per-chain ecosystem gainers for Ethereum, Base, Arbitrum, BNB Chain, Polygon, and Optimism — RANKED BY CROSS-SIGNAL ALPHA CONFLUENCE, not raw % move. Each gainer is scored by how many independent signals corroborate it (whale accumulation, cross-chain DEX trending, social/CT hype, sector rotation, multi-timeframe chart trend, AI forecast); tokens with real confluence lead and pure price-pumps are demoted. Returns: alphaRanked[] (symbol, verdict, signalCount, per-signal badges + evidence), rawMovers[] (no-confluence pumps), losers, and per-chain breakdown. Optional { params: { chain } } drills into one chain. Reads cached signals (zero extra API cost) with graceful degradation. Use to find what's actually worth attention, not just what's pumping.. It is categorised as a Read tool in the Agent Einstein — Autonomous Crypto Intelligence MCP Server, which means it retrieves data without modifying state.
Register the Agent Einstein — Autonomous Crypto Intelligence MCP server in PolicyLayer and add a rule for top_gainers_comprehensive: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Agent Einstein — Autonomous Crypto Intelligence. Nothing to install.
top_gainers_comprehensive is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the top_gainers_comprehensive rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for top_gainers_comprehensive. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
top_gainers_comprehensive is provided by the Agent Einstein — Autonomous Crypto Intelligence MCP server (https://emc2ai.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
