building-mcp-server-on-cloudflare

Builds remote MCP (Model Context Protocol) servers on Cloudflare Workers with tools, OAuth authentication, and production deployment. Generates server code, configures auth providers, and deploys to Workers. Use when: user wants to "build MCP server", "create MCP tools", "remote MCP", "deploy MCP", add "OAuth to MCP", or mentions Model Context Protocol on Cloudflare. Also triggers on "MCP authentication" or "MCP deployment". Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable skill body: concise code-first guidance, a clear multi-step workflow with validation and troubleshooting, and clean one-level-deep references that all resolve. Minor overlap between the body's Quick Start and examples.md is negligible against the overall organization.

DimensionReasoningScore

Conciseness

The body is lean throughout — retrieval-source table, numbered workflow steps, and tight code blocks — and assumes Claude's competence without explaining what MCP or Workers are, fitting the "every token earns its place" anchor rather than the padded or could-be-tightened levels.

3 / 3

Actionability

Provides fully executable bash commands (npm create cloudflare, npm start, npx wrangler deploy, codex mcp add, inspector) and complete copy-paste TypeScript (McpAgent, server.tool, fetch handler, Zod validation, env bindings), matching the top anchor for executable, specific examples.

3 / 3

Workflow Clarity

A clearly sequenced 5-step Core Workflow (Define Tools → Configure Entry → Test Locally → Deploy → Connect Clients) with an explicit test checkpoint (MCP Inspector) and a Common Issues section supplying error-recovery feedback loops, matching the anchor for explicit validation and recovery rather than mere step listing.

3 / 3

Progressive Disclosure

SKILL.md is an organized overview that defers detail to three real, clearly-signaled one-level-deep references (examples.md, oauth-setup.md, troubleshooting.md), all of which exist and none of which nest further, matching the anchor for clear overview with easy navigation rather than monolithic or poorly-signaled structure.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A high-quality description: third-person voice, concrete capabilities, and explicit trigger guidance with natural quoted terms. It clearly answers both what the skill does and when to use it within a distinct, low-conflict niche.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Builds remote MCP servers", "Generates server code", "configures auth providers", and "deploys to Workers" — matching the anchor for multiple specific concrete actions rather than the vague or partial levels.

3 / 3

Completeness

Clearly states what the skill does (capabilities listed above) and provides an explicit "Use when:" clause with concrete triggers, satisfying both halves required for the top anchor; not the level below where "when" is only implied.

3 / 3

Trigger Term Quality

Explicitly quotes natural phrases a user would say — "build MCP server", "create MCP tools", "remote MCP", "deploy MCP", "OAuth to MCP", "MCP authentication", "MCP deployment" — giving good coverage of common variations rather than jargon-only or partial keywords.

3 / 3

Distinctiveness Conflict Risk

The niche — remote MCP servers on Cloudflare Workers with OAuth — is specific and the triggers are scoped to MCP + Cloudflare, making it unlikely to fire for unrelated skills; not the vague or broadly-overlapping lower anchors.
