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 | $0.00035 | $0.02355 |
| Opus 5.5 | $0.00014 | $0.00942 |
| Sonnet 5.5 | $0.00007 | $0.00471 |
| Haiku 4.5 | $0.00003 | $0.00235 |
Grade A, and why
mcp-server-creation 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.

MCP Server Creation
Part of Agent Skills™ by googleadsagent.ai™
Description
MCP Server Creation is the skill of building Model Context Protocol servers that expose tools, resources, and capabilities to AI agents through a standardized interface. MCP has emerged as the universal integration layer for AI agent tooling — a single protocol that lets any compliant agent (Claude Code, Cursor, Codex, and others) discover and invoke server-side tools without custom integration code. Building production-quality MCP servers on Cloudflare Workers enables global, low-latency tool access with zero infrastructure management.
This skill draws from the production MCP server powering the Buddy™ agent at googleadsagent.ai™, deployed on Cloudflare Workers in the workers/buddy-agent/ directory. That server exposes Google Ads analysis tools, knowledge base search, entity memory management, and web search capabilities through MCP, making them available to any MCP-compatible client. The architecture handles authentication, rate limiting, and multi-tenant isolation at the edge.
The MCP specification defines three core primitives: tools (executable functions the agent can invoke), resources (read-only data the agent can access), and prompts (reusable prompt templates). A well-designed MCP server exposes a focused set of high-value tools with clear schemas, meaningful descriptions, and robust error handling. The transport layer supports both stdio (for local development) and SSE/HTTP (for remote deployment), with authentication integrated at the transport level.
Use When
- You need to expose custom tools to AI agents through a standardized protocol
- Building integrations that work across Claude Code, Cursor, and other MCP clients
- Deploying agent tools to Cloudflare Workers for global edge access
- Creating a tool marketplace or shared tooling infrastructure for your organization
- Migrating from proprietary tool interfaces to the open MCP standard
- Your agent needs tools that require server-side secrets or API access
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.

mcp-server-creation is a skill published in the GitHub repository itallstartedwithaidea/agent-skills (44 stars, last pushed 6mo ago), licensed MIT. It adds 35 tokens to every session and 2,355 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
