Use when building, extending, or debugging FastMCP v3 Python MCP servers — covers tools, resources, prompts, providers, transforms (including CodeMode and Tool Search), auth (MultiAuth, PropelAuth), client SDK, deployment (nginx reverse proxy), Prefab Apps, and testing. Grounded in local v3.1 docs — zero speculation.

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill's Claude Code integration docs explicitly state that MCP resources (e.g., @github:issue://...) "are fetched and included as attachments when referenced" (references/claude-code-mcp-integration.md), meaning the agent runtime will ingest open/public, user-generated third‑party content that can influence subsequent actions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.70). The skill serves UI resources that at runtime import and execute a remote JavaScript module required for the app (thus executing external code), e.g. "https://unpkg.com/@modelcontextprotocol/ext-apps@0.4.0/app-with-deps" referenced in the ui:// resource HTML, so this URL is fetched/executes during runtime and is required for the app UI to work.
