Functions exposed to the LLM to take actions

| get_sentiment_state | Get the current crypto sentiment state including Fear & Greed Index, 7-day trend, contrarian signals, and whether extreme fear/greed opportunities are active. |
| get_narrative_pulse | Identify accelerating, decelerating, and emerging crypto narratives. Shows sector rotation, momentum scores, and narrative cycle phase for positioning. |
| get_asset_context | Get deep context on a specific crypto asset: cycle position, price trend, volume health, holder behavior, risk level, and positioning guidance. Pass asset name or symbol (e.g., "bitcoin", "btc", "ethereum", "sol"). |
| get_temporal_context | Get Bitcoin halving cycle positioning: days since last halving, estimated cycle phase, historical analogs from cycles 1-3, and cycle-based guidance. |
| get_defi_health | Assess DeFi ecosystem health: total TVL, TVL trends, top chains and protocols, health score, revenue trends, and ecosystem concentration risk. |
| get_macro_context | Get macro economic context for crypto: Federal Funds Rate, DXY (dollar strength), yield curve, recession probability, and net macro impact on crypto. |
| get_onchain_pulse | Get Bitcoin on-chain health: mempool congestion, fees, miner distribution, network security, mining economics, and activity levels. |
| get_reality_check | The master tool. Synthesizes ALL data sources into a unified financial reality briefing: executive summary, risk/opportunity scores, regime, cycle, DeFi, macro, sentiment, on-chain, narratives, suggested posture, key risks, and key opportunities. Call this before any financially consequential decision. |
| set_portfolio_context | Save your portfolio holdings so Fathom can give personalized guidance. Pass an array of holdings with asset name and amount. Example: [{asset: "bitcoin", amount: 2}, {asset: "solana", amount: 50}, {asset: "usdc", amount: 10000}]. |
| get_portfolio_analysis | Get personalized portfolio analysis against current market conditions. Shows position values, allocation percentages, PnL, concentration risk, regime alignment, and specific rebalancing suggestions. Requires set_portfolio_context to be called first. |
| get_crowd_intelligence | [BETA] See what other Fathom-connected agents are doing. Returns aggregate posture distribution, consensus strength, most-queried assets, and crowd fear levels. Signal quality scales with network size. |
| get_signal_history | [BETA] View Fathom's signal log. Shows recent signals with their regimes, postures, and risk scores. Useful for tracking how conditions evolved over time. Accuracy scoring is under development. |
| set_alert | Set custom alerts that trigger when market conditions meet your thresholds. Example: [{field: "fear_greed", operator: "<", threshold: 20, label: "Extreme fear"}]. Call get_alerts to check which are triggered. |
| get_alerts | Check which of your configured alerts are currently triggered. Evaluates all alert conditions against live market data. |
| get_watchlist_report | Analyze multiple assets at once. Returns cycle position, risk level, and volume health for each. Detects state changes since last check. Max 10 assets. |
| evaluate_strategy | Evaluate a trading strategy against current market conditions. Built-in strategies: conservative_dca, momentum_rider, macro_aligned, fear_accumulator, full_defensive. Also evaluates custom strategies created with set_custom_strategy. |
| set_custom_strategy | Create a custom trading strategy with your own conditions. Then use evaluate_strategy to test it against current market conditions. |
| get_chain_context | Get DeFi context for a specific blockchain: TVL, dominance, trend, top protocols, and whether the chain is gaining or losing market share. Supports: ethereum, solana, base, arbitrum, optimism, polygon, avalanche, bsc, tron, bitcoin. |
| get_historical_context | Look up what market conditions were on a specific date. Returns regime, fear/greed, risk score, BTC price, and TVL from that date. Useful for comparing past conditions to current ones. |
| get_alternative_signals | Unconventional market signals that 99% of agents ignore. Weather in financial centers (sunshine effect), political cycle positioning (presidential year), seasonality patterns (sell in May, January effect, Santa Claus rally), and macro event calendar (FOMC, CPI, options expiry). Academically documented patterns most tools overlook. |
| set_signal_preferences | Customize which signals feed into your reality check. Turn individual signal sources on or off. Regime and sentiment are always included. Preferences persist between sessions. Example: {weather: false, political_cycle: false} to disable those signals. |
| get_account_status | Check your Fathom account: current tier, requests used this hour, available and locked tools, cache freshness, and upgrade options. Available on all tiers including free. |
| set_webhook | Register a webhook that fires when market conditions meet your criteria. Fathom evaluates conditions every 60 seconds and POSTs a JSON payload to your URL when all conditions are met. Example: alert me at my bot URL when fear_greed < 20 and regime == capitulation. Available fields: fear_greed, risk_score, opportunity_score, regime, posture, cycle_phase, tvl_change_7d, defi_health, macro_impact, net_flow_signal, leverage_signal, btc_put_call, btc_sp500_correlation, macro_risk_appetite. |
| manage_webhooks | List all registered webhooks or remove one by ID. Use action "list" to see all webhooks with their conditions, trigger counts, and last triggered time. Use action "remove" with a webhook_id to delete a webhook. |
| get_derivatives_context | Derivatives intelligence: perpetual funding rates (BTC/ETH/SOL), options data (put/call ratio, open interest, implied volatility, max pain price), and leverage positioning. Critical for understanding market positioning and liquidation risk. Data from Deribit. |
| get_stablecoin_flows | Track stablecoin supply changes across USDT, USDC, and all major stablecoins. Shows total supply, 24h/7d/30d minting and redemptions, net capital flow signal, depeg warnings, and liquidity assessment. Stablecoin flows are a leading indicator of capital entering or leaving crypto. |
| get_correlation_matrix | BTC correlation with traditional finance: 30-day Pearson correlation with S&P 500 and Gold, plus current TradFi prices. Shows whether BTC is trading as a risk asset, safe haven, or independently. Critical for understanding macro spillover risk. |
| rotate_api_key | Rotate your Fathom API key. Generates a new key, deactivates the old one, and returns the new key. The user must update their MCP config with the new key. Max 3 rotations per day. Requires Starter tier or above. |
