Build Better MCP Servers
MCP server design is difficult because agents need focused tools, clear schemas, and reliable evaluations. This skill guides planning, implementation, testing, and evaluation for Python and TypeScript MCP servers.
Stop for confirmation before installing.
Review the plan and obtain explicit user consent before changing files.
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/composiohq-mcp-builder.md and its manifest at https://skillstore.io/api/skills/composiohq-mcp-builder/manifest. Verify the artifact. Stop and obtain explicit user consent before installing or changing files.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". Plan an MCP server for a project management API.
Expected outcome:
Using "mcp-builder". Review my TypeScript MCP server before release.
Expected outcome:
Using "mcp-builder". Create evaluations for a new support ticket MCP server.
Expected outcome:
Most static findings are false positives from markdown examples, TypeScript template literals, placeholder secrets, and public documentation URLs. The real security concern is the evaluation harness, which can launch or connect to user-supplied MCP servers while forwarding headers or environment variables. No evidence found of prompt injection intended to influence this marketplace audit.

Plan tool names, schemas, response formats, and shared utilities before writing server code.
Follow language-specific guidance for validation, async API calls, error handling, and server setup.
Create realistic read-only questions and run them through an MCP evaluation harness.
Help me plan an MCP server for this API. Identify the most useful agent workflows, tool names, inputs, outputs, and evaluation questions.
Using the MCP builder guidance, create a Python FastMCP server for these workflows. Include Pydantic input models and clear error handling.
Using the MCP builder guidance, create a TypeScript MCP server with Zod schemas, strict typing, useful annotations, and concise responses.
Review this MCP server and evaluation file. Find gaps in tool design, validation, response size, error messages, and test coverage.
