MCP — AI Agents, Skills & Tools
Agents, skills, guides, tools, and commands for mcp — 33 curated resources for building with AI coding agents.
MCP Server Engineer
Use this agent to build, harden, or productionize a Model Context Protocol (MCP) server — designing tools/resources/prompts, choosing stdio vs. Streamable HTTP, taking a server remote with OAuth and stateless scaling, and testing it with the MCP Inspector. Examples — "wrap our internal API as an MCP server with three tools", "take our stdio server remote so the team can share it", "our tools confuse the model — fix the names, schemas, and descriptions".
MCP Server Scaffolder
Scaffold a new Model Context Protocol (MCP) server from a description — pick the SDK and transport, generate a typed first tool with a strict schema, and wire up MCP Inspector testing and the client-registration command. Use when starting a new MCP server and you want a correct, runnable skeleton instead of copying a README.
Building an MCP Server
An accurate introduction to the Model Context Protocol: server anatomy, transports, and connecting a tool to Claude Code.
The Best MCP Servers in 2026
The MCP servers actually worth connecting in 2026 — Context7, GitHub, Chrome DevTools, Playwright, Serena, Exa, Firecrawl, and official vendor servers.
Adding MCP Servers to Claude Code: Local, Remote, and Project-Scoped
The complete claude mcp add reference — stdio vs HTTP transports, local/project/user scopes, .mcp.json with env expansion, OAuth via /mcp, and the gotchas.
Deploying a Remote MCP Server: Stateless, Streamable HTTP, and Horizontal Scaling
Take an MCP server from local stdio to a remote, multi-user HTTP service — Streamable HTTP, stateless vs. stateful sessions, OAuth, and horizontal scaling.
Connecting and Governing MCP Servers: Registries, Gateways, and Tool Sprawl
As MCP servers multiply, discovery, trust, and tool sprawl become the problem. How registries, gateways, and curation keep a growing fleet secure and usable.
MCP Ecosystem Statistics 2026
The Model Context Protocol by the numbers — SDK downloads, server counts across registries, governance facts, and growth since the Linux Foundation donation.
MCP vs A2A: AI Agent Protocols Explained
What MCP and A2A each standardize, how Agent Cards and Tasks work, why the two protocols are complementary, and who governs them now (both Linux Foundation).
Skills vs MCP Servers: When to Use Which
Skills inject procedure into context; MCP servers expose tools and live data over a protocol. A decision framework, the combine pattern, and examples.
MCP Troubleshooting: Server Won't Connect & Other Fixes
Fixes for the MCP problems people actually hit — servers failing to connect, missing tools, OAuth loops, timeouts, truncated output, and Windows quirks.
Chrome DevTools MCP
Google's official MCP server that gives coding agents a live Chrome — Puppeteer automation plus DevTools network, console, and performance insights.
Cloudflare MCP
Cloudflare's official MCP servers — a Code Mode server covering 2,500 API endpoints in ~1k tokens, plus hosted servers for docs, Workers, and observability.
Context7
Upstash's MCP server that pulls up-to-date, version-specific library documentation into your agent's context — the cure for hallucinated APIs.
Exa
The search engine built for AIs — semantic web search, page contents, Websets, and research APIs, plus the ecosystem's most-used search MCP server.
FastMCP
A Pythonic framework for building Model Context Protocol servers and clients — decorator-based tools, resources, and prompts, with auth and deployment built in.
Figma MCP
Figma's official MCP server — structured design context, variables, screenshots, and Code Connect mappings for agents, plus write-back to the canvas.
Firecrawl
The API to search, scrape, and crawl the web for AI — clean Markdown out of any site, LLM-powered extraction, and a first-class MCP server.
Github MCP Server
GitHub's official MCP server — repos, issues, PRs, Actions, and security data for your agent, as a free hosted remote or a local Docker server.
Linear MCP
Linear's hosted MCP server — find, create, and update issues, projects, and comments from your AI agent, with OAuth and one-command setup.
MCP Inspector
The official open-source visual tool for testing and debugging Model Context Protocol servers — connect, list, and call tools, resources, and prompts.
Notion MCP
Notion's hosted MCP server — search the workspace, fetch and create pages and databases, and manage comments through Markdown-optimized agent tools.
Playwright MCP
Microsoft's open-source MCP server that gives AI agents structured browser automation via Playwright's accessibility tree.
Postgres MCP Pro
The maintained Postgres MCP server — safe SQL execution, EXPLAIN with hypothetical indexes, workload-driven index tuning, and database health checks.
Sentry MCP
Sentry's hosted MCP service for debugging — pull issues, events, traces, and releases into your agent, and trigger Seer root-cause analysis.
Sequential Thinking MCP
The official MCP reference server for structured reasoning — a sequential_thinking tool that lets agents decompose, revise, and branch their thinking.
Serena
An MCP toolkit that gives coding agents IDE-grade powers — symbol-level retrieval and editing via language servers, across 40+ languages.
Slack MCP Server
The community-canonical Slack MCP server — smart history fetch, message search, channels, reactions, and opt-in posting, after the official server was archived.
Smithery
A registry and hosting platform for Model Context Protocol servers — discover, deploy, and connect MCP servers from one place.
Stripe MCP
Stripe's official MCP server — customers, invoices, payment links, subscriptions, refunds, and docs search for agents, hosted at mcp.stripe.com.
Supabase MCP
Supabase's official MCP server — run SQL and migrations, read logs and advisors, generate types, and deploy Edge Functions, with read-only and project scoping.
Add MCP Server
Add an MCP server to the current project the safe way — pick the transport and scope, wire secrets through env vars, vet provenance, and verify the connection before trusting it.
MCP (Model Context Protocol)
MCP is the open standard for connecting AI models to external tools and data: write one server, and any MCP client — Claude Code, IDEs, agents — can use it.
