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 | $0.00054 | $0.01387 |
| Opus 5 | $0.00027 | $0.00694 |
| Sonnet 5 | $0.00011 | $0.00277 |
| Haiku 4.5 | $0.00005 | $0.00139 |
Grade B, and why
rudder-mcp-setup scanned grade B with 1 finding 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 12d 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 directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

RudderStack MCP Setup
Configure Claude Code to connect to RudderStack's hosted MCP server at mcp.rudderstack.com. Authoritative reference: https://mcp.rudderstack.com/docs.
Setup Workflow
1. Check Prerequisites ──► which npx
│
├── Found ──► Configure Claude Code
│
└── Not Found ──► Install Node.js first
2. Configure Claude Code
│
├── Option A: /mcp command (recommended)
│
└── Option B: Edit settings.json directly
3. Authenticate (OAuth) ──► Browser opens, sign in to RudderStack
4. Verify Connection ──► Restart Claude, list workspace resources
Step 1: Check Prerequisites
which npx
If found: Continue to Step 2.
If not found: Install Node.js first from https://nodejs.org/ (includes npx).
Step 2: Configure Claude Code
Option A: Using /mcp Command (Recommended)
/mcp add rudderstack
Follow the prompts:
- Server name:
rudderstack - Transport type:
http(via mcp-remote) - URL:
https://mcp.rudderstack.com/mcp
Option B: Manual Configuration
Edit your Claude Code settings file.
Settings File Locations
| Platform | Path |
|---|---|
| macOS / Linux | ~/.claude/settings.json |
| Windows | %APPDATA%\claude\settings.json |
Add MCP Server Configuration
Add under mcpServers:
{
"mcpServers": {
"rudderstack": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.rudderstack.com/mcp"]
}
}
}
Step 3: Authenticate (OAuth)
The first time you invoke an MCP tool, mcp-remote opens your browser:
- Sign in with your RudderStack account (email/password)
- Review and approve the MCP integration's requested permissions
- The browser redirects back; the session is established
No long-lived tokens to manage — OAuth handles the handshake per session.
Step 4: Verify Connection
Restart Claude Code
After configuration, restart Claude Code:
- Close and reopen the terminal session, or
- Restart the Claude Code application
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.

rudder-mcp-setup is a skill published in the GitHub repository rudderlabs/rudder-agent-skills (18 stars, last pushed 7d ago), licensed MIT. It adds 54 tokens to every session and 1,387 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
