FeathersMCP: Skill for Claude Code

.agents/skills/feathersjs-mcp/SKILL.md

feathersjs-mcp is a skill for Claude Code, Codex from feathersjs-ecosystem/FeathersMCP. It costs 169 tokens per session (4,057 once invoked), scanned A, original, MIT.

A live reference guide for FeathersJS, a JavaScript framework for building web and real-time applications. It gives an AI assistant access to FeathersJS version 6 documentation and community discussions.

In plain words
What is it for?
Use it to answer questions about FeathersJS services, hooks, schemas, authentication, WebSockets, channels, deployment, and setup in coding tools.
Why use it?
It reduces the risk of using outdated or incorrect FeathersJS advice, since the framework has changed across versions and supports several runtimes.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is feathersjs-ecosystem/FeathersMCP's own configuration. It tells Claude Code and Codex how to work on FeathersMCP itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything FeathersMCP configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

feathersjs-mcp 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 10d 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.

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.

FeathersMCP Guide

REQUIRED ACTION — do not skip this. You have MCP tools named get-menu, search-doc, get-doc, search-community, get-community-post, share-knowledge, and get-schema available in your tool palette right now. Before answering ANY FeathersJS question, you must call at least search-doc (and search-community when routing rules below apply). Do not answer from training data, from reading this file, or from memory. Call the MCP tools first, then answer using their results. FeathersJS has changed significantly across versions — your training data is unreliable for it.

Ask before assuming runtime. FeathersJS supports Node.js, Bun, Deno, and Cloudflare Workers — each has different setup, config, and deployment. If the user asks about setup, deployment, or configuration without specifying a runtime, ask which one they're targeting before searching. Do not default to Node.js.

This skill gives you live access to the complete FeathersJS v6 documentation (47 pages across API reference, guides, cookbook, and ecosystem) via the FeathersMCP MCP server.

How to Use This Skill

This skill activates for any FeathersJS question. Here's what it covers:

User need What this skill does
"How do I build X in FeathersJS?" Searches official docs, retrieves full page if truncated, supplements with community patterns
"What is X / explain Y" Grounds the explanation in retrieved doc content rather than training data
"Set up feathersjs-mcp in Cursor/VS Code/Claude Desktop" Walks through installation and activation step by step
"My MCP server isn't connecting / tools not showing" Diagnoses the problem using the troubleshooting table
"Can FeathersJS do X?" (X not in docs) Searches honestly, says "not found", suggests the nearest documented alternative
"I just built X — can I share it?" Calls share-knowledge and gives the user a GitHub link to click
"Has anyone done X with FeathersJS?" Searches community knowledge base alongside official docs

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.
