mjunaidcaSkill

building-mcp-servers

mjunaidca/mjs-agent-skills/.claude/skills/building-mcp-servers/SKILL.md

Guides creation of high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK). Covers tool design, authentication, Docker deployment, and evaluation creation. NOT when consuming existing MCP servers (use the server directly).

Add and configure custom MCP servers in Docker MCP Gateway. Use when users want to: (1) Integrate their own MCP server into the gateway, (2) Add new servers to catalogs or profiles, (3) Set up server authentication, networking, and configuration, (4) Understand MCP server integration requirements.

chohra-medSkill

mcp-server-blueprint

chohra-med/mcp-for-your-app/skills/mcp-server-blueprint/SKILL.md

Design and build a safe, useful MCP server that exposes your app's own data (analytics, funnel, revenue, crashes) to an AI assistant: read-only, least-privilege, AI-consumable. Use when someone asks "how do i build an MCP server for my app", "expose my analytics/funnel to my AI", "make my app's data reachable by Claude/Cursor", "wire an MCP over my backend", or "MCP security best practices". Enforces a security layer (read-only, field allowlist, no secrets in tool output, aggregate-not-row-level) and usability rules (Markdown output, few well-named tools) so the server helps without leaking.

tak-server

nkuntz1934/TAK-Skills/skills/tak-server/SKILL.md

TAK Server API reference covering Missions, Data Sync, WebCOP, Federation, Certificates, CoT (Cursor on Target), and server administration. Load this skill whenever the user mentions TAK, ATAK, TAK Server, CoT events, missions, data sync, WebCOP, or is building any integration that talks to a TAK Server -- even if they just say 'connect to the server' or 'send position data' in a TAK project context. Also load when you see TAK-related paths like /Marti/api/ or references to callsigns, UIDs, or mission packages.

DaveGoldSkill

rich-domain-mcp-server

DaveGold/mcp-metadata-demo/.agents/skills/rich-domain-mcp-server/SKILL.md

Guides building a NEW rich-domain MCP server or tool, and auditing an EXISTING one up to a measured reference, using Introspective Context Engineering: discover the domain from live data, name fields so they cannot be misread, deliver guidance where every target client receives it (description head, input schema, response — not the output schema, not past the host's cut), compute determinate verdicts, record provenance per rule, and measure the result. Invoke when asked to add, build, scaffold or wire an MCP server or tool; review, audit, enrich or fix tool metadata (descriptions, inputSchema, outputSchema, field names, alerts, interpretation, summaries); run a data-discovery session against an API (what does this field mean, which fields are null, probe the API); decide where discovered knowledge should be written down; prepare a domain-expert validation session; or measure a metadata change with an eval. Also triggers on "the agent picks the wrong tool", "the agent misreads this field", "the agent ignores the description", user-feedback triage, and tool-call-log pattern analysis.

Set up, connect, validate, and repair Claude Desktop and MCP servers using Desktop Commander — inspecting and fixing mcp.json / claude_desktop_config.json, getting MCP servers to connect, and diagnosing local AI tooling. Use when a user wants to install, configure, connect, validate, or fix Claude Desktop, an MCP server, an MCP config file, or a local AI agent/gateway. Trigger on the symptoms that actually bring people in: "Claude can't see my tools", "my MCP server isn't showing up", "tools aren't loading in Claude", "add an MCP server", "my MCP isn't connecting", "fix my Claude Desktop config", "the agent won't respond", "wire up Ollama / LM Studio", "restart Claude Desktop". Also covers local agent gateways like OpenClaw and Hermes.
