CONNECTED
MODE.
Everything in Local mode, plus a marketplace of tool servers your agent can search and run, workflows it can build and run, and an encrypted Vault for credentials. Access is limited for now — join the waitlist to get in.
LOCAL STORAGE. CLOUD EXECUTION.
Steroid MCP and Steroid Flows are cloud platforms that plug into the agents on your machine. Their operations run in the cloud, not on your device — worth knowing before you connect.
STEROID MCP
Tools run on Steroid's cloud gateway, not on your machine. Results and the credentials a run needs are held only temporarily for that run, and expire automatically.
STEROID FLOWS
Your workflows run in the cloud, so the flows you build and the encrypted connections they use are stored there, ready whenever a flow is called.
STEROID VAULT
Every credential is stored encrypted on your machine, not on Steroid servers. A cloud tool receives only the values its run needs, and a flow keeps an encrypted copy of the connections it uses.
STEROID MCP
What it is
A unified MCP gateway that exposes 200+ servers through exactly 2 tools — search_tools and run_tool. Your agent searches for what it needs at runtime and executes it, instead of loading every server upfront. No context bloat, no hallucinated tool names. The gateway runs tools on your behalf in the cloud and holds their results and credentials only temporarily, for the run.
Features
Dynamic discovery, isolated execution, secure credential injection, a random ten-character process-local handle for each discovered tool, and short-lived handling of tool results and credentials.

STEROID FLOWS
What it is
A deterministic flow builder for AI workflows. Instead of prompting an agent to follow steps and hoping it does, you define each step as a block — LLM nodes, MCP blocks, conditionals, webhooks — and the engine executes them in order, every time, with full tracing.
Features
Workflows exposed as REST APIs, SSE webhooks for real-time updates, LLM nodes powered by your IDE/Coding Agent subscription, efficient data flow between nodes.

STEROID VAULT
What it is
An encrypted credential store shared across every IDE connected to the Steroid ecosystem. Every credential is stored encrypted on your machine: API keys never appear in config files and never touch LLM context. You don't even need to enter secrets upfront — when your agent runs a tool for the first time and the credential is missing, Steroid MCP elicits it during execution, stores it securely in the Vault, and from the next run onward the secret is injected automatically. The LLM simply asks for the tool — it has zero awareness of the secret management happening underneath.
Features
Just-in-time secret elicitation on first use, automatic injection on subsequent runs, cross-IDE credential sharing, and AES-encrypted local storage with tamper detection.

THE NUMBERS DON'T LIE.
Every number below is sourced. Every problem is live in production today. Every fix ships with Steroid Kit.
| PROBLEM | THE REALITY | WITH STEROID KIT |
|---|---|---|
Context Window Bloat | Connect GitHub, Slack, and Sentry — 3 servers, ~40 tools — and 55K tokens are gone before your agent reads a single message. GPT-5 scores just 43.7% on real-world MCP tasks. Tool accuracy degrades rapidly as servers scale. | STEROID MCP 200+ servers through 2 tools. ~500 tokens total overhead. 99.7% of your context preserved. |
Tool Hallucination | Even frontier models complete only 43–54% of real-world MCP tool tasks. Smaller reasoning models hallucinate tools up to 74% of the time — and alignment cuts it to 56% while degrading utility. Tool accuracy collapses as servers scale. | STEROID MCP Workflow-enforced discovery + a random ten-character process-local handle per discovered tool. The LLM can only run tools it discovered first. |
Plaintext Secrets | 100% of MCP setups store API keys in plaintext JSON. Indirect prompt injection exfiltrates credentials with up to 88% success. 315 MCP vulnerabilities identified in 2025 alone. | STEROID VAULT AES-encrypted local vault. Secrets elicited just-in-time on first use, then injected automatically. Shared across every connected IDE. The LLM never sees credentials — it just calls the tool. |
Skills Can't Orchestrate | Skills embed workflow instructions in plain text — the LLM can skip, reorder, or hallucinate steps. SkillsBench shows top models achieve only 44–49% success even with curated skill scripts across 84 tasks. Without enforcement, a skill saying "commit, update Jira, write Confluence wiki" is a suggestion — not a guarantee. | STEROID FLOWS Replace instructions with a Flow API call. The skill triggers one endpoint — the flow engine enforces every step end-to-end. The LLM can't skip what it doesn't control. |
Skills Run on Hope | Today's skills rely on plain-text instructions and shell scripts executed in sequence — the LLM decides whether to follow them. A 10-step skill at 95% per-step reliability delivers only 59.9% end-to-end success. Scripts break across OS, shells, and environments. There is no retry, no tracing, and no guarantee any step ran. | STEROID FLOWS Replace scripts with a Steroid Flows API call. The skill triggers one endpoint — the flow engine handles every step with full tracing, retries, and 100% execution guarantee. Same skill, 4× more reliable, works identically on every OS. |
No Tool → API Bridge | You can build a skill, but you can't expose a multi-tool AI workflow as a REST endpoint. There's no bridge between "LLM can use tools" and "my system can call a reliable pipeline." | STEROID FLOWS Set a webhook trigger, chain tool nodes + LLM nodes, end with a response node — your workflow is now a REST API. 1 flow, callable from anywhere. |
Token Cost Explosion | MCP costs 4–32× more tokens than alternatives. One user's 3-server setup turned a $2 chat into $47. Monthly at 10K ops: $3.20 (CLI) vs $55.20 (MCP). | STEROID MCP Constant low overhead regardless of server count. Search + run architecture — nothing loaded upfront. |
Setup Hell | 7–12 manual steps per server. JSON editing, env vars, restarts, debugging — per IDE, per server. 70% of devs manage 2–7 servers simultaneously. | STEROID CLI 1 curl command. IDE configured, vault set up, 200+ servers ready. Zero re-configuration. |
Zero Sandboxing | Local MCP servers run with full user permissions. Files, network, env vars — all exposed. 50% of builders cite security as their #1 challenge. | STEROID MCP Cloud-isolated runtimes. No foreign code runs on your machine. Request in, response out. |
Ecosystem Chaos | 16,000+ MCP servers. 97M+ monthly SDK downloads. No unified access. Every developer reinvents the wheel. | STEROID MCP One gateway. 200+ curated servers. Access grows automatically — every server doubles as a block in your flows. |
