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 | $0.00122 | $0.02201 |
| Opus 5.5 | $0.00049 | $0.00880 |
| Sonnet 5.5 | $0.00024 | $0.00440 |
| Haiku 4.5 | $0.00012 | $0.00220 |
Grade A, and why
mcp-management scanned grade A with 2 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.
Reads agent configuration directorieslowAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
| Config location | `~/.claude/settings.json` | `~/Library/Application Support/Claude/claude_desktop_config.json` | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Discovering MCP Servers
Primary Registries
| Registry | Servers | Best For |
|---|---|---|
| Official MCP Registry | Canonical | Verified, authoritative source |
| GitHub MCP Registry | Curated | GitHub-native, one-click VS Code install |
| Smithery.ai | 4,600+ | Usage metrics, edge deployment |
| Glama.ai | 10,000+ | Hosted option, no local setup |
| PulseMCP | 7,500+ | Daily updates, streaming focus |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-management is a skill published in the GitHub repository clearfunction/cf-devtools (5 stars, last pushed 9mo ago), licensed Apache-2.0. It adds 122 tokens to every session and 2,201 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
