What is templui-mcp-server CLAUDE.md?

Development instructions for a TemplUI MCP server, which gives AI assistants access to Go interface components and documentation for the templ templating language.

Use them when working on the server's TypeScript code, build process, tests, development workflow, or release process.

They document how to install, build, test, run, and publish the server, reducing uncertainty when developing or maintaining it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03047	$0.03047
Opus 5.5	$0.01219	$0.01219

Security

Grade C, and why

templui-mcp-server CLAUDE.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
