Tools

Lets agents run terminal commands on your machine, manage long-running processes, and read, write, search and diff-edit files. Extends the official Filesystem server; collects pseudonymized telemetry by default (no file contents or command arguments), which you can turn off in config.

Processes CSV, TSV, JSON and other structured data like awk, sed, cut, join and sort, but by field name, for cleaning, aggregation, format conversion and pretty-printing. The command is mlr; written in Go with no runtime dependencies.

Open-source research agent: one command runs literature reviews, deep research, paper reviews, paper-code consistency checks and replication plans, searching arXiv, PubMed and more with sources recorded. Good for grad students writing reviews. Run feynman setup to sign in to a model provider.

Linter and formatter for 20+ SQL dialects that auto-fixes most issues and handles Jinja templating and dbt projects (dbt needs a plugin), suited to warehouse code review and CI.

Official AWS MCP that queries CloudWatch metrics, alarms and logs, analyzes log anomaly patterns and recommends alarm settings, helping agents with root cause analysis. Requires AWS credentials.

Lets agents query AWS bills, cost trends, budgets and spending anomalies, and recommends Savings Plans, Reserved Instances and rightsizing. Maintained by AWS; requires AWS credentials.

Official AWS MCP for managing FHIR health data in AWS HealthLake: CRUD, advanced search, full patient records, and import and export, with a read-only mode to prevent changes. Needs an AWS account, a paid HealthLake data store and local AWS credentials; clinical conclusions need professional review.

Official AWS MCP that validates CloudFormation templates for syntax and security compliance, diagnoses deployment failures, and searches CloudFormation and CDK docs, code samples and best practices. Replaces the deprecated Cloud Control API server; needs AWS credentials.

Official AWS MCP to create and manage EKS clusters, deploy apps, manage Kubernetes resources, and read pod logs and events for troubleshooting. Read-only by default; writes need --allow-write and reading logs needs --allow-sensitive-data-access.

Official AWS MCP that searches and reads AWS documentation, converts it to Markdown for agents to cite, and suggests related pages. No AWS credentials needed; requires uv.

Extracts the main content of a web page, stripping comments, sidebars, headers and footers, and outputs clean HTML or Markdown with metadata like title, author and publish date, saving tokens when agents read the web. Built for Obsidian Web Clipper by kepano; still in development.

Distributed data integration tool and Apache top-level project with 160+ connectors for batch, real-time and CDC sync. Define jobs in config files and run them on the built-in Zeta engine or on Flink or Spark. Requires Java.

Rendering engine that lays out HTML and CSS and exports PDF, supporting paged media and other print style standards, ideal for generating reports, invoices and receipts in bulk. Written in Python; depends on the system Pango library.

NVIDIA's open-source LLM vulnerability scanner that probes for prompt injection, jailbreaks, data leakage, hallucination and harmful content, supporting OpenAI, Hugging Face, Bedrock and most REST-accessible models. Scanning cloud models needs their API keys.

Annotate and review agent-generated plans, docs and code diffs in the browser, then send feedback back to the agent in one click. Hooks into plan mode and supports Claude Code, Codex and other agents. Run the official install script to set up the CLI first.

High-accuracy retrieval-augmented Q&A over paper PDFs, text and Office documents, filling in citation metadata, checking retractions and attaching traceable sources to answers. Provides the pqa CLI and a Python library. Needs an LLM API key by default; local models can be configured.

Terminal tool for exploring and wrangling tabular data: opens dozens of formats including CSV, JSON, Excel and SQLite for filtering, sorting, pivots and frequency counts. --batch mode replays actions headlessly or converts file formats.

Tencent's open-source browser bridge: through the bsk CLI and a Chrome/Edge extension, agents use your logged-in accounts in a separate visible window to browse, fill forms and take full-page screenshots, and correlate network requests with console output to debug sites.

Git worktree manager (wt) built for running multiple AI agents in parallel: create, switch and clean up worktrees by branch name, and spin up a worktree and launch Claude in one command. Supports hooks, LLM-generated commit messages and one-step merges.

Uses a strong model to audit your codebase and list evidence-backed issues across correctness, security, performance and testing, writes a plan a cheaper model can execute, and reviews the results. It never edits code itself. By shadcn.

Say build a harness for this project and it designs a domain-specific agent team, generating subagent definitions, companion skills and orchestration, validates them and keeps evolving them from feedback. Supports workflow orchestration, persistent agent teams and subagent delegation.

Static scanner for security and compliance issues in Terraform, CloudFormation, Kubernetes, Helm, Dockerfiles and CI pipeline configs, with over a thousand built-in policies and hard-coded secret detection. Outputs SARIF, JSON and more. Maintained by Prisma Cloud.

Manage database schemas as code: declare the desired schema in SQL, HCL or your ORM and Atlas plans, lints and applies migrations, and can export existing databases as HCL, SQL or Mermaid ER diagrams. Supports PostgreSQL, MySQL and a dozen other databases.

Converts the output of 100+ commands such as dig, ps, ls and ifconfig, plus common file formats, into JSON so agents can parse it reliably with jq or scripts. Also usable as a Python library.
