Hey Design AI
Hey Design AI MCP

Give your agent design direction.

Let your AI builder search a curated website design prompt library, compare directions, and retrieve the exact build brief inside its working context — before it starts generating another generic page.

Research before rendering

A better brief changes the build.

Most agents can write the components. The missing piece is a concrete design decision they can defend.

Hey Design AI MCP gives the model structured, copy-ready art direction at the moment it needs it. The agent can search by problem or category, inspect concise metadata, and pull one complete prompt into the same context where it is planning and coding.

Structured prompt metadata, not a pile of screenshots
Server-side Premium checks on every MCP request
Bearer keys you can rotate from your account

Three focused tools

Small surface. Useful context.

The server exposes only what an agent needs to move from an open-ended design question to a buildable brief. Search is separate from retrieval, so the model can compare first and spend a daily unlock only when it chooses a new locked prompt.

01
search_design_prompts

Search before choosing

Find prompts by keyword or exact category and receive IDs, titles, descriptions, access state, and the current daily balance.

No unlock charged
02
get_design_prompt

Retrieve the complete build brief

Fetch the full prompt text by ID. A new locked prompt uses one daily unlock; free or previously unlocked prompts do not charge again.

1 new prompt
03
get_mcp_usage

Check access and remaining quota

Let the agent confirm the active Premium plan, expiration time, UTC quota date, and remaining daily unlocks before it retrieves anything.

No unlock charged

Premium access boundary

Generous enough to explore. Finite by design.

MCP access belongs exclusively to Premium annual. The same entitlement system powers the website and MCP, so a prompt unlocked in either place stays in your library and never consumes another daily slot.

Required access

20

New locked prompts20 per UTC day
Catalog search and usage checksNo unlock cost
Daily reset00:00 UTC

The limit counts newly unlocked locked prompts, not MCP requests. Free prompts and prompts already in your library remain retrievable without using another slot.

Connect your tool

One endpoint. Your working context.

Create a key in your account, keep it private, then add the Streamable HTTP endpoint to your preferred MCP client. The server authenticates every call and rechecks Premium status before returning tools or prompt content.

  1. 1Activate Premium annual access. Standard annual and single-prompt purchases do not enable MCP.
  2. 2Create a dedicated API key in Account → API Keys so you can rotate it without affecting other tools.
  3. 3Add the configuration, restart or reload your client, then ask it to search Hey Design AI prompts.

Streamable HTTP endpoint

https://heydesign.ai/api/mcp

Keep the token in an environment variable, then register the remote server with the Codex CLI.

export HEYDESIGN_API_KEY="sk_..."

codex mcp add heydesign \
  --url https://heydesign.ai/api/mcp \
  --bearer-token-env-var HEYDESIGN_API_KEY
