mcp-reference-servers SKILL.md skillA
mcp-reference-servers from tuliosousapro/saas-blueprint is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tuliosousapro/saas-blueprint/mcp-reference-servers@git:20260520.0aeaf85Pins git:20260520.0aeaf85 in mdr.lock. Pin the fingerprint instead.

Guidance on using and integrating official reference servers. Use when building custom servers or deploying standard configurations. For server listings, see mcp-server-registry.
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 Reference Servers Skill
## When to Use
- When building new MCP servers and needing a reference implementation.
- When the user wants robust, community-tested servers for common tools (Filesystem, Google Search, Fetch, etc.).
- When debugging MCP connection issues using standardized servers.
## Reference
[MCP Reference Servers GitHub](https://github.com/modelcontextprotocol/servers)
## Instructions
### 1. Identify Target Server
- Review the `src` directory in the reference repository to see available servers.
- Common servers include:
- `fetch`: For web page scraping.
- `filesystem`: For local file access.
- `google-search`: For web searching capabilities.
- `postgres`: For database interaction.
### 2. Implementation & Setup
- Most reference servers are built with Node.js/TypeScript or Python.
- Follow the `README.md` within each sub-directory for build and run instructions.
- Ensure the appropriate runtime (Node.js 18+ or Python 3.10+) is installed.
### 3. Usage via MCP Configuration
```json
{
"mcpServers": {
"server-name": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-name"],
"env": {
"ENV_VAR": "value"
}

How to install
mdr add tuliosousapro/saas-blueprint/mcp-reference-servers@sha256:11fd8d3241c88925The line at the top of this page pins the label git:20260520.0aeaf85, 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.
