Build HTTP servers with effect/unstable/http — HttpRouter routes and middleware, HttpServerRequest schema decoding, HttpServerResponse constructors, multipart uploads, websocket upgrades, static files, NodeHttpServer/BunHttpServer layers, and in-memory web handlers. Use when serving raw HTTP routes, reading request bodies/cookies/uploads, writing server middleware, streaming responses, or testing handlers without a real port.
Use when the user needs to create, manage, or operate Hetzner Cloud servers, including power management, SSH access, server types, images, snapshots, backups, rescue mode, placement groups, ISOs, or viewing locations and datacenters.
Stand up the `body` MCP for the foundational "Body" add-on on a new machine and wire it into both Claude clients — an in-repo thin fetch-wrapper over the board's /api/body/* routes (like the nutrition/fitness servers). Body is the single owner of body identity, the weight + body-composition series, and the free-text objective that Nutrition + Fitness read. Its writes are add-on-gated (attributed to the agent via `x-actor`) and its reads are open. It is exposed to Claude Code via a supergateway + launchd BRIDGE on $BODY_BRIDGE_PORT/:8012 and to Claude Cowork Desktop as a direct stdio command. The add-on HARD AUTO-ENABLES whenever Nutrition or Fitness is enabled (so it is usually already on). Use when setting up the body add-on on a new machine, when Cowork or Code can't see the `body` server, when the body bridge (:8012) is down, when a body write 404s, or when wiring the /body surface.
Scaffold production-ready Python MCP servers using FastMCP. Use when creating new MCP servers, initializing MCP projects, generating server boilerplate, or setting up MCP development environments. Supports all MCP primitives (tools, resources, prompts) with Pydantic validation, async patterns, and proper project structure.
This skill should be used when the user asks to "create an MCP server", "build MCP tools", "add MCP resources", "create MCP prompts", "implement MCP protocol", "deploy MCP server", "create AI tools", "expose API as MCP", "build Claude tools", "create LLM tools", or mentions FastMCP, MCP server, Model Context Protocol, MCP tools, MCP resources, MCP prompts, or server composition.
Expert skill for building Model Context Protocol (MCP) servers with tool definitions for AI agents. Specializes in Official MCP SDK for Python, tool schema design, and integration with OpenAI Agents SDK.
This skill should be used when the user asks to "add MCP server", "integrate MCP", "configure MCP in plugin", "use .mcp.json", "set up Model Context Protocol", "connect external service", mentions "${CLAUDE_PLUGIN_ROOT} with MCP", or discusses MCP server types (SSE, stdio, HTTP, WebSocket). Provides comprehensive guidance for integrating Model Context Protocol servers into Claude Code plugins for external tool and service integration.
Convert OpenAPI v3 specifications into MCP servers using HAPI CLI. Supports local, Docker, and Cloudflare Workers deployment. Zero code required. Use when you need to expose API functionality as MCP tools or deploy API-based services to multiple hosting platforms.
Inbound mail-server protocol hardening for mid-2026 — SMTP smuggling, STARTTLS command/response injection, IMAP/POP3/ManageSieve command injection, Sieve redirect exfiltration, open relay, mailbox-DAV traversal/XXE, and cleartext-AUTH (the server-side protocol layer that SPF/DKIM/DMARC do not protect)
Build a robust host-side FastMCP (Model Context Protocol) service that survives restarts and reboots, reconnects cleanly to a Dockerized MCP gateway/agent, and auto-recovers its own dependency. Use when standing up an MCP server (tool server) for an agent — especially on macOS with launchd and a containerized gateway. Trigger on "build an MCP server", "MCP keeps dropping / Session not found", "MCP service won't stay up", "register MCP with the gateway", or "host.docker.internal MCP".
Building a CrateStack HTTP server — include_server_schema! with db = Postgres or db = None, the generated Cratestack runtime and Axum routers, AuthProvider wiring, the REST query-parameter contract, error envelope, codecs, events and the transactional outbox, idempotency and rate-limit layers, and the signed-transport EnvelopeLayer (envelope / cose features, COSE-signed requests, envelope_layer). Load when working in a crate that depends on package = "cratestack-pg" or "cratestack-api", or when a question concerns generated routes, 403/404/422 behaviour, list filters, or router() arguments.
Download, install, update, or maintain the IMR Biotic DuckDB database with BioticExplorerServer. Use compileDatabase() for first-time setup and updateDatabase() for routine refreshes. Use when the user wants to set up the database, update it to newer data, fix a missing or outdated database, or check its location. Handles intranet checks, monitored background jobs, incremental changed-year updates, and safe full rebuilds when schemas change.
Specialized skill for building production-ready serverless applications on AWS. Covers Lambda functions, API Gateway, DynamoDB, SQS/SNS event-driven patterns, SAM/CDK deployment, and cold start optimization.
Configure AWS MCP servers for documentation search and API access. Use when setting up AWS MCP, configuring AWS documentation tools, troubleshooting MCP connectivity, or when user mentions aws-mcp, awsdocs, uvx setup, or MCP server configuration. Covers both Full AWS MCP Server (with uvx + credentials) and lightweight Documentation MCP (no auth required).
Provides connectivity, authentication, and troubleshooting guidance for Amazon RDS for SQL Server. Applicable when users ask about SSMS times out connecting from EC2, Cannot generate SSPI context with Windows auth, connect RDS SQL Server from Lambda with pymssql, auth_scheme shows NTLM instead of KERBEROS on ECS Fargate, SSM tunnel to RDS SQL Server from laptop, port 1433 security group, TrustServerCertificate=True for localhost tunnels, SPN MSSQLSvc, AWS Managed Microsoft AD, CNAME not RDS endpoint for Kerberos, tds_version='7.4', encryption='require', port-as-string for pymssql, Secrets Manager credential caching in Lambda, error 18456 login failed. Covers Python (pymssql, pyodbc), .NET (Microsoft.Data.SqlClient), Java (JDBC mssql-jdbc), Node.js (tedious), IAM auth via RDS Proxy, and VPC/ECS/EKS/Lambda deployment.
Use when a user needs structured Talordata SERP results through installed Talordata MCP for Google, Bing, Yandex, DuckDuckGo, news, images, videos, maps/local, shopping, SEO ranking, price/news/local monitoring, fresh public search data, or research with source links.
Stores, retrieves, and manages data as objects in Cloud Storage (Google Cloud Storage, or GCS) buckets. Use when you need to interact with Cloud Storage — set up a Storage MCP server (remote or local Toolbox), create or configure buckets, upload, download, stream, or transfer data, organize objects with folders, generate signed URLs, control access (IAM, ACLs, public access prevention), set storage classes (Standard, Nearline, Coldline, Archive), manage lifecycle and cost, protect data (versioning, CMEK, retention, Bucket Lock, holds, soft delete), host static websites, trigger Pub/Sub notifications, mount buckets (gcsfuse), or optimize performance. Covers gcloud storage / gsutil, JSON/XML APIs, client libraries, Terraform, and Cloud Storage MCP servers. Don't use for non-Storage MCP servers, block storage (Persistent Disk), BigQuery, or databases (Cloud SQL, Spanner, Bigtable, Firestore).
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
