Description from the maker (original English)
Polymarket & Kalshi sentiment from X (Twitter) via Grok. Free daily scores; live scoring via x402.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

| Tool | Price | What it returns |
|---|---|---|
get_daily_scores | free | Today's X-sentiment score for each market we track, with the change since yesterday |
get_catalog, get_pricing, get_sample, get_health | free | Routes, prices, example output, status |

get_sentiment_shift(q) | $0.35 | Change in sentiment since the previous score |
get_market_sentiment(q) | $0.35 | Fresh score -100..100, catalyst and volume trend for any market question |

Add this URL as a remote MCP server (streamable HTTP):
https://prediction-bot-iggf.onrender.com/mcp
For example, in a client that takes a JSON config:
{
"mcpServers": { "prediction-bot": { "type": "http", "url": "https://prediction-bot-iggf.onrender.com/mcp" } } }
Free tools work straight away. The hosted server never pays for anyone: paid tools return the x402 price quote (price, network, pay-to) so your own x402 client can pay, or use option 2.
Requires uv:
{
"mcpServers": { "prediction-bot": { "command": "uvx", "args": ["prediction-bot-mcp"], "env": { "PREDICTION_BOT_EVM_PRIVATE_KEY": " ", "PREDICTION_BOT_MAX_USD_PER_CALL": "0.50", "PREDICTION_BOT_SESSION_BUDGET_USD": "1.00" } } } }
Without a wallet key, free tools work and paid tools return the x402 payment quote instead of paying.
With a wallet key, paid tools pay automatically. The server never pays more than PREDICTION_BOT_MAX_USD_PER_CALL per call or PREDICTION_BOT_SESSION_BUDGET_USD per session. Use a dedicated low-balance wallet. The key stays on your machine and is only used to sign USDC payments.
| Env var | Default | Purpose |
|---|---|---|
PREDICTION_BOT_API_BASE | https://prediction-bot-iggf.onrender.com | API base URL |
PREDICTION_BOT_EVM_PRIVATE_KEY | unset | Enables auto-pay |
PREDICTION_BOT_MAX_USD_PER_CALL | 0.50 | Hard cap per paid call |
PREDICTION_BOT_SESSION_BUDGET_USD | 1.00 | Cap per server session |
Scores run from -100 (very bearish on the question) to +100 (very bullish), based on recent X posts about the market. They reflect public discussion, not a forecast, and are not financial advice.
