Build MCP Servers with mcp-use
MCP developers need consistent patterns for tools, resources, prompts, and widgets. This skill summarizes mcp-use implementation patterns and warns that new work should use mcp-app-builder.
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "mcp-builder" from https://skillstore.io/skills/shubhamsaboo-mcp-builder.md and its manifest at https://skillstore.io/api/skills/shubhamsaboo-mcp-builder/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Using "mcp-builder". Build a weather tool with a widget.
Expected outcome:
A short implementation plan with the tool schema, widget name, response helper, and environment variable setup.
Using "mcp-builder". Add a user profile resource.
Expected outcome:
A resource design with a parameterized URI, user identifier validation, structured profile data, and not-found handling.
Using "mcp-builder". Create a code review prompt.
Expected outcome:
A prompt template specification with described fields, completion guidance, and response helper selection.
Most static findings are false positives from Markdown code fences, TypeScript template literals, environment variable examples, and localhost URLs. One real issue remains: the deprecated skill asks users to run an npx installer for a replacement skill. No prompt injection text or credential exfiltration intent was found.
These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Design tool schemas, response helpers, and error handling for mcp-use servers.
Define resources and resource templates for configuration, profiles, and other structured data.
Connect server-side MCP tools to React TSX widget files and visible tool output.
Create a basic mcp-use tool for this task: [task]. Include schema fields, descriptions, response helper choice, and error handling.
Design MCP resources and prompts for this server: [server goal]. Separate read-only data from actions and explain each URI pattern.
Plan a widget-backed MCP workflow for [user workflow]. Include tool names, widget props, model-visible output, and loading states.
Review this mcp-use server plan for production readiness. Check schemas, destructive actions, environment variables, widgets, and deployment assumptions.

Improve UX With Research-Led Design Guidance
Teams often design flows from assumptions and miss accessibility issues. This skill guides research, structure, interaction design, and review using UX best practices.
Plan Projects with Clear Tasks and Milestones
Complex projects are hard to scope, sequence, and estimate. This skill turns a goal into milestones, task tables, dependencies, risks, and checkpoints.
Analyze Academic Research Faster
Academic research tasks often require careful reading, synthesis, and citation discipline. This skill helps structure paper reviews, literature summaries, and scholarly writing with consistent academic standards.
Improve Writing With Clear Editing
Unclear writing can hide good ideas and slow review. This skill edits grammar, tone, structure, and concision for cleaner drafts.
Evaluate Strategic Business Decisions
Strategic choices often lack clear comparison of options, risks, and success measures. This skill structures decisions into analysis, recommendations, roadmaps, and metrics.
Build Full-Stack Web Applications
Teams lose time when frontend, API, database, and deployment choices are handled separately. This skill guides Claude, Codex, and Claude Code through full-stack application planning and implementation.
