Run a composable MCP test server by hand — pick the showcase config for a feature or bug, build it, and connect with the right protocol era. Use when a change, a PR or a smoke test needs a real server to exercise it; when reproducing a reported bug by hand; when choosing which fixture or protocol era to run; when a fixture keeps serving stale code after an edit; or when the config or preset you need does not exist yet.

Converts one @packages/server unit spec from mocha (test/unit/**/*_spec.ts) to vitest (*.spec.ts) without changing what the test proves. Use when migrating a server unit spec, when a converted spec passes but its mocks may not be intercepting, or when the user mentions spec_helper, mockery, proxyquire, sinon, snap-shot-it, or the mocha/vitest split in packages/server.

Review the implementation source code of MCP (Model Context Protocol) servers, clients, and tool handlers against a security baseline — authentication, sessions, rate limiting, input-schema validation, official-SDK usage, RCE vectors, and the OWASP MCP Top 10 — producing a report with file/line evidence. Use this skill when: - Reviewing an MCP server implementation for security before release - Checking a server against the baseline controls (MCP-01 to MCP-05) and the OWASP MCP Top 10 - Auditing tools for RCE vectors (command/code injection, unsafe deserialization, path traversal, SSTI, dependency hijacking, SSRF) - Verifying auth, session, rate-limiting, and input-validation controls on a network-exposed server - Reviewing MCP client code that handles untrusted server responses and session IDs - Requests like "review this MCP server for security" or "is my MCP server implementation secure?"

Access MCP (Model Context Protocol) servers and their tools, resources, and prompts through the mcpdo CLI — connections it holds extend your capabilities alongside any built-in MCP support. Use this skill for any question or task about MCP servers, connections, or tools (e.g. "what MCP servers am I connected to?", "what MCP tools do I have?"), and whenever a task requires inspecting, testing, or scripting against an MCP server (stdio or HTTP) rather than writing custom client code.

Runs one workflow prompt through Instance AI, Claude Code with the n8n MCP server, and Codex with the n8n MCP server on a local n8n instance. Collects the traces, per-call tokens, cost, and canvas screenshots, judges each run against the expected outcome, and builds one HTML comparison page. Claude Code and Codex run in a sandbox that sees only the n8n MCP server. Use when the user wants to compare builders, test a prompt across Instance AI and MCP, or says /testmax-n8n-ai.

Audit MCP (Model Context Protocol) server configurations for security issues. Use this skill when: - Reviewing .mcp.json files for security risks - Checking MCP server args for hardcoded secrets or shell injection patterns - Validating that MCP package-runner dependencies use exact reviewed versions, not bare names, @latest, or ranges - Detecting mutable npm/npx, bunx, pnpm dlx, yarn dlx, npm exec, uvx, uv tool run, and pipx run references in MCP configurations - Auditing which MCP servers a project registers and whether they're on an approved list - Checking for environment variable usage vs. hardcoded credentials in MCP configs - Any request like "is my MCP config secure?", "audit my MCP servers", or "check .mcp.json" keywords: [mcp, security, audit, secrets, shell-injection, supply-chain, governance]

Build Model Context Protocol (MCP) servers in C#/.NET against the current ModelContextProtocol 2.x NuGet packages. Helps with cases the model gets wrong without guidance — stale versions (0.x preview or 1.x-era defaults), the v2 stateless-by-default HTTP flip, the 2026-07-28 spec deprecations (roots/sampling/logging), MCP Apps and Tasks extension packages, elicitation URL mode, per-session HTTP wiring, OAuth and reverse-proxy deploy specifics, and debugging MapMcp / STDIO / Streamable-HTTP errors. Also covers STDIO and Streamable HTTP transports (SSE is deprecated), tools, prompts, resources, completions, and a basic .NET MCP client. Trigger when the user says or implies any .NET MCP server work: ModelContextProtocol, McpServerTool, MapMcp, WithStdioServerTransport, "MCP server in C#", "MCP tool in dotnet", "expose this as MCP", or names a primitive (prompt/resource/elicitation/MCP App) in a .NET context. Skip for MCP work in other languages.

Serves and consumes Skills over MCP (SEP-2640, the `io.modelcontextprotocol/skills` extension) with v2 of the MCP TypeScript SDK: publishes a folder of `SKILL.md` skills from an MCP server with `loadSkills` and `SkillsExtension`, and lists, verifies and loads them in a client or host with `SkillsClient`. Use whenever a TypeScript project on `@modelcontextprotocol/server` or `@modelcontextprotocol/client` 2.x wants to expose agent skills from its MCP server, serve `skill://` resources or `skills/list`, or load skills from the MCP servers it connects to, even if the user does not say "SEP-2640" or "extension". Not for projects still on v1 (`@modelcontextprotocol/sdk`: upgrade them with the `mcp-typescript-sdk-upgrade-to-v2` skill first), for MCP SDKs in other languages (Python, Go, C#), or for writing the content of a `SKILL.md`.

Stores, retrieves, and manages data as objects in Cloud Storage on Google Cloud (also known colloquially as 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 generic MCP setup that doesn't mention Cloud Storage, other MCP servers, block storage (Persistent Disk), BigQuery, or databases (Cloud SQL, Spanner, Bigtable, Firestore).

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.

Operate a LangBot instance through its built-in MCP (Model Context Protocol) server.

Covers the /mcp endpoint, API-key auth (web-UI lbk_ keys and the config.yaml global key), the tool surface, and client configuration. Triggers on "langbot mcp", "manage langbot via mcp", "langbot /mcp", "langbot mcp server".

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.
