mcp-builder SKILL.md skillA

mcp-builder from kanevry/session-orchestrator is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add kanevry/session-orchestrator/mcp-builder@git:20261003.c34ec50

Pins git:20261003.c34ec50 in mdr.lock. Pin the fingerprint instead.

Use when creating a new MCP (Model Context Protocol) server, extending an existing one, or debugging tool discoverability/performance. Guides through research → implementation → test → eval phases with TypeScript-first guidance matching our stack. Trigger on phrases like "build an MCP server", "expose X as an MCP tool", "write MCP tools for Y", "integrate Z via MCP".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MCP Server Development

Adapted from [anthropics/skills/mcp-builder](https://github.com/anthropics/skills/tree/main/skills/mcp-builder). MCP-server quality is measured by how well it lets LLMs accomplish real-world tasks — not by endpoint count.

## Stack default for our projects

- **Language:** TypeScript (matches our stack; static typing + Zod schemas + good LLM code-gen)
- **Transport:** `stdio` for local tools, **Streamable HTTP (stateless JSON)** for remote
- **SDK:** [`@modelcontextprotocol/sdk`](https://github.com/modelcontextprotocol/typescript-sdk)
- **Package manager:** pnpm (never npm/yarn in our repos)

## Phase 1 — Research & Plan

### 1.1 Design principles

**API coverage vs. workflow tools.** Balance comprehensive endpoint coverage with specialized workflow shortcuts. Default to coverage unless you have a clear reason — agents compose basic tools well; workflow tools ossify.

**Tool naming & discoverability.** Consistent prefix + action verb. Examples:
- `github_create_issue`, `github_list_repos`
- `gitlab_search_issues`, `gitlab_close_mr`

**Context management.** Return focused, paginated data. Agents suffer when a single tool call floods context.

How to install

The exact contents, by fingerprint

mdr add kanevry/session-orchestrator/mcp-builder@sha256:cb9f2f32d0d6565a

The line at the top of this page pins the label git:20261003.c34ec50, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
