## MCP tools (5)

### `full-web-search` (~153 tokens)

Search the web and fetch complete page content from top results. This is the most comprehensive web search tool. It searches the web and then follows the resulting links to extract their full page content, providing the most detailed and complete information available. Use get-web-search-summaries for a lightweight alternative.

Input parameters:

- `includeContent` (boolean|string): Whether to fetch full page content (default: true)
- `limit` (number|string): Number of results to return with full content (1-10)
- `maxContentLength` (number|string): Maximum characters per result content (0 = no limit). Usually not needed - content length is automatically optimized.
- `query` (string, required): Search query to execute (recommended for comprehensive research)

### `search-gdweb-designs` (~196 tokens)

Use this tool only when the user wants a lightweight list of GDWEB references. It applies the dashboard-managed exclusion list before returning results, returns metadata for multiple results, and does not generate implementation documents. For layout analysis, frontend specifications, DESIGN_INDEX files, or implementation planning, use generate-gdweb-design-indexes instead so every result is processed by a separate isolated LLM request.

Input parameters:

- `awardOnly` (boolean|string): Whether to require a non-empty GDWEB award field. Defaults to true.
- `includePreviousYear` (boolean|string): Whether to include the previous year in addition to the target year. Defaults to true.
- `limit` (number|string): Number of GDWEB design results to return (1-10)
- `query` (string, required): Natural-language design reference query to search directly on GDWEB
- `year` (number|string): Target award/registration year. Defaults to the current runtime year.

### `generate-gdweb-design-indexes` (~325 tokens)

Automatically use this tool when the user asks to find GDWEB references and create layout analysis, frontend specifications, implementation plans, or DESIGN_INDEX files. This tool applies the dashboard-managed exclusion list, performs the GDWEB search internally, and sends one completely separate MCP sampling/createMessage request per non-excluded result. Each isolated request contains only one result and has no previous-result context. It writes one page-by-page, measurement-first DESIGN_INDEX_gdweb-<strNo>.md file before starting the next request, then returns only file paths and statuses to the calling LLM. Never replace this tool with search-gdweb-designs plus a combined summary. The connected MCP client must support sampling.

Input parameters:

- `awardOnly` (boolean|string): Whether to require a non-empty GDWEB award field
- `includePreviousYear` (boolean|string): Whether to include the previous year
- `language` (string): Language for every generated document. Defaults to English; choose Korean for Korean output.
- `limit` (number|string): Number of isolated result requests and output documents (1-10)
- `maxTokens` (number|string): Per-work output budget for a complete multi-page specification (131,072-262,144 tokens; default 131,072)
- `outputDirectory` (string): Directory for generated DESIGN_INDEX files. Defaults to DESIGN_INDEX_OUTPUT_DIR or ./design-index.
- `query` (string, required): Natural-language design query to search directly on GDWEB
- `year` (number|string): Target award/registration year. Defaults to the current runtime year.

### `get-web-search-summaries` (~94 tokens)

Search the web and return only the search result snippets/descriptions without following links to extract full page content. This is a lightweight alternative to full-web-search for when you only need brief search results. For comprehensive information, use full-web-search instead.

Input parameters:

- `limit` (number|string): Number of search results to return (1-10)
- `query` (string, required): Search query to execute (lightweight alternative)

### `get-single-web-page-content` (~105 tokens)

Extract and return the full content from a single web page URL. This tool follows a provided URL and extracts the main page content. Useful for getting detailed content from a specific webpage without performing a search.

Input parameters:

- `maxContentLength` (number|string): Maximum characters for the extracted content (0 = no limit, undefined = use default limit). Usually not needed - content length is automatically optimized.
- `url` (string, required): The URL of the web page to extract content from

## Common questions

### What is the Secret MCP server?

Secret MCP is listed in the public MCP registry as io.github.yyeongjin/secret-mcp. Local MCP server for isolated, evidence-backed GDWEB design analysis and web search. This page covers its npm package (secret-design-mcp).

### Is the Secret MCP server safe to use?

Secret MCP scores 80 out of 100 on VerifyMCP. We recorded 2 known advisories against it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Secret MCP server expose?

Secret MCP exposes 5 tools: full-web-search, search-gdweb-designs, generate-gdweb-design-indexes, get-web-search-summaries, get-single-web-page-content. Their descriptions and schemas cost roughly 873 tokens of context every time the server is loaded.

### Is the Secret MCP server still maintained?

Secret MCP is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Secret MCP server under?

Secret MCP declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
