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 | $0.03038 |
| Opus 5.5 | $0.00022 | $0.01215 |
| Sonnet 5.5 | $0.00011 | $0.00608 |
| Haiku 4.5 | $0.00005 | $0.00304 |
Grade C, and why
rudder-mcp-setup scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
| Tools not appearing | Restart Claude Code; check `settings.json` syntax with `python3 -m json.tool ~/.claude/settings.json` | Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
- Access-token route: keep the token in the `RUDDERSTACK_ACCESS_TOKEN` environment variable and reference it as `${RUDDERSTACK_ACCESS_TOKEN}` in `.mcp.json`. Never write the token into `.mcp.json` or any other committed How it starts

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.
Choose an auth route
The server accepts two kinds of credentials on two endpoints:
| Route | Endpoint | Credential | Use it for |
|---|---|---|---|
| OAuth (default) | https://mcp.rudderstack.com/mcp |
Browser sign-in, run by the client | People and coding agents in an interactive client |
| Access token | https://mcp.rudderstack.com/bearer-auth-mcp |
Authorization: Bearer <token> plus X-Workspace-ID: <workspace id> headers |
Headless sessions that cannot open a browser, such as CI |
Use OAuth, coding agents included. Use the access-token route only when the session cannot open a browser. The access-token route is in Access-token route below; Steps 1 to 3 cover OAuth.
Setup workflow (OAuth)
1. Add the server ──► claude mcp add --transport http rudderstack https://mcp.rudderstack.com/mcp
2. Sign in (OAuth) ──► /mcp, choose rudderstack, Authenticate, approve in the browser
3. Verify ──► list the sources in one of your workspaces
Step 1: Add the server
Run claude mcp list first. If it shows a server at https://mcp.rudderstack.com/mcp, under plugin:rudder-core:rudderstack (the rudder-core plugin's entry) or any other name, the server is already added. Skip this step and authenticate that entry in Step 2. Adding rudderstack as well is redundant. Claude Code hides a plugin's server when a server you added has the same URL, so /mcp would then list only rudderstack.
Claude Code talks to the server over HTTP and runs the OAuth sign-in itself, so it needs no npx or mcp-remote:
claude mcp add --transport http rudderstack https://mcp.rudderstack.com/mcp
The default scope is this project, for you only. Add --scope project to write it to the project's .mcp.json for everyone who clones the repository, or --scope user for all your projects.
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 (19 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 3,038 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (reads agent configuration directories, reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
