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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.02757 |
| Opus 5.5 | $0.00025 | $0.01103 |
| Sonnet 5.5 | $0.00013 | $0.00551 |
| Haiku 4.5 | $0.00006 | $0.00276 |
Grade B, and why
rudder-mcp-workflow scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
- Access-token route: the token stays in `RUDDERSTACK_ACCESS_TOKEN` and `.mcp.json` references it as `${RUDDERSTACK_ACCESS_TOKEN}`. Never write the token into a config file and never ask the user to paste it into the cha How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RudderStack MCP Workflow
RudderStack's hosted MCP server at mcp.rudderstack.com exposes a RudderStack workspace as an MCP endpoint so AI agents (Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, or any MCP client) can inspect and drive workspace resources via tool calls. Authoritative docs: https://mcp.rudderstack.com/docs.
When to use
The user wants an AI agent to drive RudderStack, mentions RudderStack + MCP, asks about mcp.rudderstack.com, or wants to configure MCP tool access for a RudderStack workspace.
Preflight
Before running any workflow, verify:
- Your MCP client is configured to connect to
https://mcp.rudderstack.com/mcp(OAuth, the default) orhttps://mcp.rudderstack.com/bearer-auth-mcp(access token). Seerudder-mcp-setupfor the Claude Code walkthrough of both; the official docs cover Claude Desktop, Cursor, VS Code, Windsurf, and the claude.ai web UI. - OAuth route: browser sign-in to your RudderStack account completed on first tool use. Access-token route:
RUDDERSTACK_ACCESS_TOKENwas exported in the shell that started the client, and theX-Workspace-IDheader holds the workspace ID. -
mcp.rudderstack.comis reachable on port 443 from your network.
Client configuration
If claude mcp list already shows a server at https://mcp.rudderstack.com/mcp or https://mcp.rudderstack.com/bearer-auth-mcp, under plugin:rudder-core:rudderstack (the rudder-core plugin's entry) or any other name, use it and add nothing. For an /mcp entry, choose it in /mcp and Authenticate. A /bearer-auth-mcp entry has no sign-in, so check that RUDDERSTACK_ACCESS_TOKEN is exported in the shell that started the client, as the access-token route in rudder-mcp-setup says. Adding a server under a name that the project's .mcp.json already uses writes a local entry that hides the project's one.
Otherwise, Claude Code connects over HTTP and runs the OAuth sign-in itself, with no npx or mcp-remote:
claude mcp add --transport http rudderstack https://mcp.rudderstack.com/mcp
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-workflow is a skill published in the GitHub repository rudderlabs/rudder-agent-skills (19 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 2,757 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
