Runs SQL statements in memory against real PostgreSQL 18 and SQLite 3.49 engines after loading your schema and sample rows, returning each statement's own verdict: errors with line, column, and hints, constraint violations, or the resulting rows. It also compares both dialects to expose portability differences, all with no database server, network, or API key.

Enables prioritizing vulnerabilities by real-world exploitation evidence, combining CISA KEV, EPSS, CVSS, and SSVC to rank CVEs and package versions, and providing fix recommendations.

Enables checking project files like Dockerfile, .nvmrc, and CI workflows to determine whether pinned runtime, database, and OS versions are still supported, providing end-of-life dates, latest patches, and upgrade targets for 470+ products.

Explains cron expressions in plain English, checks them for errors and gotchas, lists next run times in any time zone, and converts between Unix cron, GitHub Actions, Kubernetes, AWS EventBridge, Quartz and Spring dialects.

Searches US product recalls across CPSC, FDA, and NHTSA in one call, matching by name, brand, model number, UPC, or VIN with confidence scoring.

Enables agents to validate Dockerfiles for build-breaking syntax errors, risky patterns like root users and secrets in ENV/ARG, and cache-order problems, returning every finding with its line and a fix. It also verifies referenced container images against public registries, reporting tag existence, digests to pin, supported platforms, last rebuild time, and end-of-life status with an upgrade tag.

Answers upgrade questions from a package's own changelog, listing breaking changes, deprecations, security fixes, and raised requirements between two versions, retrieving notes for a single version, and searching changelog entries for specific APIs or options.

Provides comprehensive email deliverability and domain registration analysis, evaluating SPF, DKIM, DMARC, DNS records, and expiry to identify issues and suggest fixes.

Finds the clearest Sentinel-2, Landsat, Sentinel-1, or NAIP scene for any location and time, ranked by area coverage, cloud cover, and date, with previews and band download links.

A full finance desk for your AI agent: 355 tools in one free server with no API key, reading SEC filings, earnings guidance, insider trades, options, rates and macro data from the source, plus quant analytics and backtest validation. The agent sees 5 tools and searches the rest, so it stays light on context.

Runs a regular expression on real engines — JavaScript (V8), Python (CPython re), PCRE2 and RE2 — reporting each engine's own compile errors with positions, every match with its groups and named groups, replacement results, and where the engines disagree. It also detects catastrophic backtracking (ReDoS), naming the at-risk part of the pattern, generating an attack string, and timing how long each engine actually takes on it.

Provides authoritative open source license answers: SPDX identification, copyleft classification, and compatibility checks of dependencies against your project's license.

Enables verifying citations in reference lists and BibTeX by detecting fabricated or mismatched references and retractions, and returning corrected BibTeX.

Enables agents to validate and normalize phone numbers, email addresses, and postal addresses with production-grade, country-specific rules, including formatting, typo detection, and checks for disposable domains or fictional numbers.

Enables coding agents to retrieve exact RFC section text, status and obsoleted-by chains, errata, and IANA registry values such as HTTP status codes, media types, and port numbers.

Provides accurate time zone conversions, DST-safe scheduling, holidays for 200+ countries, business day calculations, and cross-zone meeting slot suggestions.

Enables agents and users to validate Kubernetes manifests (YAML/JSON, multi-document) against the API of a chosen Kubernetes version without needing a cluster. It reports removed or deprecated APIs with replacements, unknown or misspelt fields, misconfigurations the API server would reject, Pod Security Standard violations, and common risks, each with file, line, and fix.

Check a backtest before trusting it: deflated Sharpe, CSCV overfitting, minimum track record length, breadth ceiling and paper-evidence checks. Deflated Sharpe and track record are tested in CI against the papers' worked examples, CSCV against CRAN pbo. Runs hosted with no signup, or fully on your machine in private local mode. Also reads SEC-reported company financials by ticker.

Enables reviewing GitHub Actions workflows for outdated actions, deprecated Node runtimes, retired runners, deprecated commands, and security risks, with file, line, and fix for each finding.

Answers medication questions from official FDA labels with section citations, resolves drug names via RxNorm, and reports FDA recalls and shortages.

Enables reading web pages and PDFs as clean Markdown, extracting main content and letting agents query for relevant passages, outline sections, search in-page, and list links while respecting robots.txt and blocking private addresses.

Enables checking packages across npm, PyPI, Go, Maven, Cargo, NuGet, and RubyGems for existence, deprecation, known vulnerabilities, and license issues before installation, providing verdicts like does_not_exist, risky, verify, or ok.

Enables agents to validate JSON, JSONC, YAML, and TOML configuration files against official SchemaStore schemas, pinpointing errors and likely key misspellings, and to look up schema-backed setting details.

Enables email and domain checks, including SPF lookup limits, DKIM keys, DMARC, DNS records, and registration expiry.

Enables agents and users to explore 117 open benchmark problems, check candidate certificates against exact offline sandboxed checkers, compare values to best-known records, and retrieve verified results, replays, and citations. Every check yields a verdict and exact value, never an estimate.

Enables AI assistants to search and read an open quant research record: papers, topics, killed candidates, trial counts, live paper-trading sleeves, and a tamper-evident chain head. It provides six read-only tools over public CDN files, returning each source's stated limits alongside paper-execution-only caveats.

Enables AI agents to retrieve and cross-check public market, company, filing, economic, and alternative data from primary sources, including SEC filings, financial statements, screening, insider activity, options, prediction markets, DeFi metrics, and central-bank and macroeconomic series. Results include source URLs and evidence so answers can be cited and verified.

Enables local, keyless quantitative finance analysis across performance and risk, options and exotics, fixed income, portfolio construction, econometrics, technical indicators, strategy backtests, and data/ML labeling on user-supplied data without network calls.

Enables AI agents to build point-in-time factors from SEC filings and run cross-sectional signal backtests on locally supplied prices, with lookahead blocked in code, costs and market impact charged on real trades, crisis and out-of-sample checks, and every variant logged so the best run is judged against the whole search.

Enables AI assistants to look up SEC company fundamentals point in time: what a company first reported, what was known on any given date, and which values were later restated, with the filing behind each value. Supports querying history over time, tracing every vintage of a period, and resolving measures such as revenue or EPS across the XBRL tags a company has used.
