Descriptive statistics for an array of numbers: count, sum, mean, median, mode, min, max, range, variance, stddev, and percentiles.

Compute the full descriptive-stats panel for an array of numbers in one call: count, sum, mean, median, mode, stddev (sample), variance, min, max, range, q1, q3, IQR. Beats calling 12 separate tools when you already have the array in front of you.

Split text into overlapping chunks for RAG ingestion - by characters (default) or by exact LLM tokens. Returns the chunks plus offsets. Deterministic, no model needed.

Convert between epoch (s or ms), ISO 8601, and any IANA timezone. Give a value (epoch seconds or milliseconds, an ISO string, or 'now'), get every representation back: utc, epochSeconds, epochMillis and, with tz, timezone, localIso (ISO 8601 with the zone's offset, e.g. 2026-06-11T19:00:00+09:00), utcOffset and local (a display string). A bare number under 1e12 is read as seconds, otherwise as milliseconds.

Count exact LLM tokens for a string using the real OpenAI BPE (o200k_base for gpt-4o/o-series, cl100k_base for gpt-4/gpt-3.5). Deterministic, offline - budget context windows without calling a model.

Base wallet lookup / address balance: ETH balance, transaction count (nonce) and whether the address is a smart contract or an ordinary wallet (EOA), live from Base mainnet in one call. Use it to check a counterparty, deposit address or contract before paying it. Input: address (0x...). For token balances or any other read use chain.rpc.

Validate a UUID and report its version (1-8) and variant. Accepts hyphenated or braced forms.

Bluesky data, live and keyless: a profile with its latest posts and engagement (likes, reposts, replies, quotes), an account search, or a post thread with its replies, from the public AppView. Use it for social listening and influencer checks on Bluesky. Input: mode (profile, search_actors, thread) with actor, query or uri; optional posts, limit, depth.

SEC filings / company fundamentals: revenue, net income, diluted EPS, operating income, assets, liabilities, equity, cash and shares outstanding by quarter and year (10-K, 10-Q) as the company reported them to the SEC, from EDGAR's official XBRL API at call time. Name any other XBRL line item; restatements resolve to the latest filing. Input: symbol (US ticker) or cik; optional concepts, periods, forms.

Heuristic user-agent string parser: browser, version, OS, device class, and bot detection.

Parse YAML into JSON (safe schema - no code execution).

Base transaction lookup by hash: sender, recipient, ETH value, block, success or failure, gas used and log count, with the receipt folded in, live from Base mainnet. Use it to confirm a payment or transfer landed on-chain. Input: hash (the 0x transaction hash). For the raw receipt use chain.rpc.

YouTube search and video stats, live: search YouTube or look up videos by id, each with title, channel, upload time, duration, views, likes, comments, live flag and thumbnail from the YouTube Data API at call time. Sort by relevance, date, views or rating; filter by upload date, country and language. Input: query or video_ids; optional max_results, order, published_after, region_code.

Base RPC endpoint, pay per call: any allowlisted read-only JSON-RPC method on Base mainnet (eth_call, eth_getBalance, eth_getLogs, eth_getBlockByNumber, eth_getTransactionReceipt and more) with your own params, no API key. Revert reasons come back as the result. Input: method; optional params.

Top prediction market events: Polymarket events (groups of related markets) ranked by trading volume, with title, slug, end date and market count. Use it to see what the biggest prediction markets are right now. Input: optional limit.

Top GitHub repositories by language and/or topic (optionally newer than a date), ranked by stars/forks/recently-updated: name, full_name, stars, language, description, url, pushed_at. From the official GitHub Search API.

Exchange rates / currency conversion table: Coinbase's full rate table for one base currency against every crypto and fiat currency it quotes (USD to BTC, ETH, EUR, GBP, JPY...). Use it to convert amounts between currencies. Input: currency code such as USD.

Static application-security scan of a single code blob for CWE Top-25 logic bugs (SQL injection, XSS, command injection, SSRF, path traversal, insecure deserialization, weak crypto and more). Pass the code and its language; returns a verdict with per-finding CWE, severity and line. Static indicators, not a guarantee.

OpenAI-compatible chat completion, priced by counted input tokens + max output tokens at per-model rates

Base network status and gas price: current block height and gas price (wei and gwei), live from a Base mainnet RPC node. Use it to check Base is moving, time an on-chain action or estimate gas before sending a transaction. Keyless, pay per call. No input needed.
