auth0/auth0-mcp-server is a local MCP server that lets language models and AI agents communicate with Auth0 Management APIs. It enables users to administer Auth0 tenants with natural-language requests, including creating applications, deploying Actions, checking logs, and managing users. The catalogue entries are instructions, a plugin, and an MCP integration for using these operations from compatible AI tools.

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 | $0.01010 | $0.01010 |
| Opus 5.5 | $0.00404 | $0.00404 |
| Sonnet 5.5 | $0.00202 | $0.00202 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
auth0-mcp-server AGENTS.md 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 1mo 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.

What This Is
An MCP (Model Context Protocol) server that lets AI assistants interact with the Auth0 Management API. It exposes Auth0 operations as "tools" an LLM can call.
Commands
npm run dev # Run with tsx (no build needed)
npm run build # Compile TypeScript → dist/ (runs format + lint first)
npm run typecheck # Type check without emitting
npm run test # Run vitest once
npx vitest run test/tools/applications.test.ts # Single test file
npm run lint:fix # Auto-fix lint issues
npm run format # Prettier format
Architecture
Request path: src/server.ts validates each tool call (token expiry, rejects undeclared parameters) → src/tools/index.ts dispatches to domain handler → handler calls Auth0 API → src/utils/response-masker.ts redacts secrets before the response reaches the LLM.
Key directories:
src/tools/— one file per domain (applications, actions, logs, forms, etc.). Each exports tool definitions and handlers.src/auth/— two flows:device-auth-flow.ts(browser OAuth2, primary) andclient-credentials-flow.ts(M2M for private cloud).src/clients/— per-client config managers (Claude, Cursor, Windsurf, VS Code, Gemini) that write MCP config into each tool's config file.src/commands/— CLI commands:init(auth),run(start server),logout,session.src/utils/— shared utilities; notable:config.ts(credential loading),tools.ts(filtering logic),response-masker.ts.
Tool System
Tools are named auth0_<verb>_<resource> (e.g. auth0_create_application, auth0_list_logs). Read operations carry readOnly: true in _meta.
To add a tool: define it in src/tools/<domain>.ts, add the handler, register both in src/tools/index.ts.
Tools are filtered at startup by glob patterns (--tools / AUTH0_MCP_TOOLS) and a read-only flag (--read-only / AUTH0_MCP_READ_ONLY=true). Read-only takes priority over patterns.
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.

auth0-mcp-server AGENTS.md is an instructions file published in the GitHub repository auth0/auth0-mcp-server (121 stars, last pushed 7d ago), licensed MIT. It adds 1,010 tokens to every session, about $0.0040 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
