Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00224 | $0.00224 |
| Opus 5.5 | $0.00090 | $0.00090 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
aim scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Project Aim
Python to TypeScript Port
The aim of this project is to port the duckduckgo-mcp-server-python implementation to TypeScript (duckduckgo-mcp-server). When porting code:
- Refer to the original implementation of the Python files
- Replicate their logic faithfully in TypeScript
- Ensure the core functionality remains identical
- Maintain the same logical structure and components
Requirements
-
Logic Preservation: The TypeScript implementation MUST maintain the same logical flow and behavior as the Python version.
-
Component Naming: Core components should maintain conceptual naming parity with the Python version.
-
Architecture: Follow the same architectural patterns and separation of concerns as the Python implementation.
-
File Organization: Mirror the Python project's organizational structure where appropriate, adapting to TypeScript conventions.
Implementation Notes
- Use TypeScript's type system to enhance the original Python implementation
- Apply language-specific best practices for TypeScript while preserving the original logic
- Adapt Python-specific patterns to TypeScript equivalents where direct ports aren't possible
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

aim is a cursor rule published in the GitHub repository HeiSir2014/duckduckgo-mcp-server (3 stars, last pushed 7mo ago), licensed MIT. It adds 224 tokens to every session, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. It comes from a forked repository.

vue-typescript-patterns
A set of coding rules for Vue 3 projects using TypeScript, a language that adds type checking to JavaScript. It covers component structure, file locations, TypeScript usage, and Pinia, a library for shared application state.

Cursor rule "general-rule" from vinhnx/vtchat, covering development guidelines, tech stack & project overview, package management, code style and ui/ux design principles.
ts
A set of TypeScript coding rules covering types, naming, file organization, error handling, and strict type checking. TypeScript is JavaScript with checks that help catch many mistakes before the program runs.
naming-conventions-rule
A small set of naming rules for TypeScript, Node.js, and Next.js projects. It defines how directories and React components should be named and exported.
typescript-security
