Mcp Tactics

mcp-tactics

A Claude Code Skill: the cross-cutting tactics book for [nlink-jp](https://github.com/nlink-jp)'s 21 MCP servers and 2 proxies ([ADR-003](https://github.com/nlink-jp/.github/blob/main/adr/003-mcp-tactics-skill.md), amended by [ADR-018](https://github.com/nlink-jp/.github/blob/main/adr/018-mcp-observability-tiers.md)). `SKILL.md` is a router of decision tables — input artifact → route, cross-server chains, and a four-tier escalation doctrine ranked by who can see that you asked, from no external observer up to contact from your own IP — with per-domain playbooks under `references/`. It records selection and ordering only; each server's own `get_usage` tool stays authoritative for parameters and error recovery.

Install

Download `mcp-tactics-vX.Y.Z.zip` from [Releases](https://github.com/nlink-jp/mcp-tactics/releases), then register it:

• In the app (Claude Desktop, claude.ai, mobile) — add the zip from the skill settings (Customize → Skills). Prefer this route; it survives changes to where skills are stored on disk.
• Claude Code — unzip mcp-tactics-vX.Y.Z.zip -d ~/.claude/skills/, or into a project's .claude/skills/ for a project-scoped install.

From a checkout:

make install

That builds the release zip and unpacks *that*, so what you run is what a release ships — a packaging defect breaks your install rather than reaching users. `make install DEST=/path/to/skills` installs elsewhere; `make uninstall` removes it.

Usage

This is a reference skill: Claude loads it on its own when a task involves one of the organization's MCP servers, and `/mcp-tactics` shows it on demand.

Development

make check     # structural validation (frontmatter, relative links)
make package   # build dist/mcp-tactics-vX.Y.Z.zip (zip root = skill folder)

The skill content lives in [`mcp-tactics/`](mcp-tactics/) — that directory is exactly what `make package` ships and `make install` copies. Repository scaffolding (README,
