30/60/90-day cash flow forecasts for small businesses: reads receivables, payables and collections from your accounting system, PayPal or Stripe (or an uploaded CSV), gives a forecast with ranges and risk flags, and exports to Excel. Have an accountant review. Official from Anthropic.

Tax prep for US small business owners: estimates quarterly taxes from QuickBooks, Xero or an uploaded P&L, and at year end lists contractors paid over $600 for 1099-NEC, flagging missing W-9s, for your accountant. US federal only; books must be closed. Not tax advice. From Anthropic.

For preclinical life sciences research: bundles MCP connectors for PubMed, bioRxiv, ChEMBL, Open Targets, ClinicalTrials and more, plus analysis skills for single-cell RNA QC, scvi-tools and nf-core pipelines. Official from Anthropic; some data sources need accounts.

Month-end reconciliation for small businesses: matches QuickBooks or Xero line by line against PayPal, Stripe and Shopify payouts, flags likely duplicates and missing receipts, explains the P&L in plain terms and exports a close package (Excel and PDF). CSVs work too. Official from Anthropic.

Grafana's load and performance testing tool: write test scripts in JavaScript covering HTTP, WebSocket, gRPC and browsers, set threshold assertions and run them in CI.

Processes large tool outputs in a sandbox and returns only the results to context; logs session events in SQLite with FTS5 so work continues after context compaction. Supports Claude Code, Codex and a dozen other clients. ELv2 licensed.

Compensation analysis for HR and managers: market pay percentiles by role, level and location, offer competitiveness checks and equity modeling; upload a pay sheet to find employees outside their band and flight risks. Without a comp data source it uses public web data, so verify. By Anthropic.

Checks hours before payroll for US small businesses: totals regular time, overtime and PTO from Gusto, QuickBooks Payroll or timesheets, and flags missed punches, overtime anomalies, rate changes and mid-period hires or exits. Prepares only, never runs payroll. Official from Anthropic.

Data analysis plugin: writes queries in each SQL dialect, explores datasets, runs statistical tests, charts with Python and builds interactive HTML dashboards, then reviews methods and conclusions before sharing. Connects to Snowflake, BigQuery and other warehouses. Official from Anthropic.

Runs commands and scripts in a sandbox, indexes large tool outputs for full-text search and returns only results to the context window to save tokens; after compaction it can retrieve edits and task state. Supports Claude Code, Codex and more. Needs Node.js 22.5+.

Methodology reference for US SOX 404 internal control audits: scoping significant accounts, sampling methods, workpaper and evidence standards, and classifying deficiencies, significant deficiencies and material weaknesses. Not audit or legal advice; needs professional review. By Anthropic.

For internal auditors running SOX tests: lists key controls by area (revenue, procure-to-pay, payroll, close, ITGC) and period, sets sample sizes, samples from your population, and generates test workpaper templates and deficiency assessments. Needs professional review. Official from Anthropic.

Finance and accounting plugin: prepares journal entries, reconciles accounts, generates income statements, runs variance analysis, manages month-end close and supports SOX audit testing. Can pull data from ERPs and data warehouses. Official from Anthropic.

Helps accountants prepare month-end journal entries: debit/credit treatment for accruals, prepaid amortization, depreciation, payroll and revenue recognition, plus required support and review checklists, following US GAAP. Not financial advice; review before posting. From Anthropic's finance plugin.

Official web auditing tool from the Google Chrome team: score pages on performance, accessibility, best practices and SEO from the command line and get HTML, JSON or CSV reports, so agents can iterate on a page. Needs Node 22+ and Chrome.

Gives coding agents IDE-like symbol-level code search, editing and refactoring via language servers (LSP) across 40+ languages, with cross-session memory. An optional paid JetBrains plugin backend adds breakpoint debugging. Install with uv first.

Open-source infrastructure-as-code tool and community fork of Terraform: describe cloud resources declaratively, run plan to generate an execution plan, then apply changes, creating resources in parallel by dependency graph. Community-governed, MPL-2.0.
