Search DailyMed drug labels, SPLs, NDCs and packaging. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the DailyMed connector, then ask in plain words. The AI picks the tools.
For pharmacists and drug-information researchers who check FDA drug labels on DailyMed.
The AI searches labels by drug name and shows setid, title, version and publish date. It can first check the exact spelling of brand and generic names.
The AI fetches the full label as XML for a setid. It can pull out indications, dosage, warnings, boxed warning and adverse reactions.
The AI lists every published version of a label with its date. You see when the labeling was updated.
The AI reads the NDC codes and packaging descriptions of a label. You see which package sizes and codes exist for a drug.
The AI reads product names and active ingredients with their strength, and lists the product and packaging images of a label.
The AI searches labels with one of these codes, and can list RxCUIs or UNII codes to find the right one.
You do not need an account or a key for DailyMed. You log in with your email address and a 6-digit code.
DailyMed needs no credential.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"dailymed": {
"url": "https://dailymed.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"dailymed": {
"type": "http",
"url": "https://dailymed.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your email address and a 6-digit code. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+ | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this DailyMed server only. Ask your AI to run dailymed_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with dailymed_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with dailymed_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by DailyMed. The server calls the public DailyMed API for you.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
Only an email address. You do not need a key for DailyMed.

All 12 DailyMed tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this DailyMed server only. Cancel any time: your paid plan then runs to the end of the paid period. Run dailymed_usage_status to see how many calls you used.
Ask the AI to run dailymed_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run dailymed_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with dailymed_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
