mcp▌

Create MCP servers using the C# SDK and .NET project templates. Covers scaffolding, tool/prompt/resource implementation, and transport configuration for stdio and HTTP. USE FOR: creating new MCP server projects, scaffolding with dotnet new mcpserver, adding MCP tools/prompts/resources, choosing stdio vs HTTP transport, configuring MCP hosting in Program.cs, setting up ASP.NET Core MCP endpoints with MapMcp. DO NOT USE FOR: debugging or running existing servers (use mcp-csharp-debug), writing tests (use mcp-csharp-test), publishing or deploying (use mcp-csharp-publish), building MCP clients, non-.NET MCP servers.

Test C# MCP servers at multiple levels: unit tests for individual tools and integration tests using the MCP client SDK. USE FOR: unit testing MCP tool methods, integration testing with in-memory MCP client/server, end-to-end testing via MCP protocol, testing HTTP MCP servers with WebApplicationFactory, mocking dependencies in tool tests, creating evaluations for MCP servers, writing eval questions, measuring tool quality. DO NOT USE FOR: testing MCP clients (this is server testing only), load or performance testing, testing non-.NET MCP servers, debugging server issues (use mcp-csharp-debug).

Use the Valet CLI (or 1-click Deploy URL fallback) to create, deploy, and manage AI agents that live inside Slack and handle research, follow-up, sync, and reporting for Sales, Venture, Finance, Product, Compliance, Procurement, Engineering, and Nonprofit teams.

Resolve an exact Packrift packaging SKU for a buyer requirement, confirm live price and inventory through the Packrift MCP server, and return a measured cart handoff URL or a bulk-quote URL when no exact match exists. Treats dimensions, material, color, adhesive, printer compatibility, case count, and SKU as strict exact-match constraints — never substitutes nearby SKUs.

Discover live startup raises on Hiveround — filter by keyword, stage, and max raise via the site's MCP server (anonymous reads) or the ECP HTTP endpoints, returning slug, name, stage, sector, raise amount, founder handle, and listing URL. Read-only.

Mint a one-time-use payment credential (virtual card PAN or Shared Payment Token) from a user's Link wallet so an agent can complete a purchase on their behalf. User approves each spend request from the Link mobile app; real card details never reach the agent.

Search, browse, and look up books on Books Mandala (Nepal's largest dedicated online bookstore, 50,000+ titles including deep Nepali / South-Asian literature). Returns title, authors, ISBN, NPR price, stock status, genres, and a canonical purchase URL. Uses Books Mandala's public MCP server (no auth) by default, with REST API and browser fallbacks documented.

Install, authenticate, and verify the @auto.dev/sdk npm package so a downstream agent can run any Auto.dev automotive data task (VIN decode, listings, photos, specs, recalls, payments, APR, TCO, plate-to-VIN, taxes) via the global `auto` CLI, the bundled stdio MCP server, or the JS/TS SDK.

Search the AgentPowers marketplace for skills, agents (subagents), and plugins by keyword, type, and category — returning slug, title, description, type, price, security status, install/download counts, rating, author, and source (native vs. external like ClawHub).

Model Context Protocol (MCP) enables Claude Code plugins to integrate with external services and APIs by providing structured tool access. Use MCP integration to expose external service capabilities as tools within Claude Code.
