Hybrid

🚀 OneSearch MCP-Server: Websuche & Crawl & Scraper & Inhaltsaufbereitung

Eine Implementierung eines Model Context Protocol (MCP)-Servers, die sich für Websuche, lokale Browsersuche und Scraping-Funktionen mit agent-browser in mehrere Suchanbieter integriert.

Funktionen

Websuche, Scraping, Crawling und Vorverarbeitung von Inhalten von Websites.
Unterstützung mehrerer Suchmaschinen und Web-Scraper: SearXNG, Tavily, DuckDuckGo, Bing, Google, Zhipu (智谱), Exa, Bocha (博查) usw.
Lokale Websuche (Browsersuche), Unterstützung mehrerer Suchmaschinen: Bing, Google, Baidu, Sogou usw.
- Verwendung von agent-browser für Browser-Automatisierung.
- Kostenlos, keine API-Schlüssel erforderlich.
Aktivierte Tools: one_search, one_scrape, one_map, one_extract

Related MCP server: Firecrawl MCP Server

Migration von v1.1.0 und früher

Breaking Changes in v1.1.0:

Firecrawl entfernt: Die Firecrawl-Integration wurde zugunsten von agent-browser entfernt, das ähnliche Funktionen bietet, ohne externe API-Dienste zu erfordern.
Neue Browser-Anforderung: Sie müssen den Chromium-Browser installieren (siehe Abschnitt Voraussetzungen).
Umgebungsvariablen: FIRECRAWL_API_URL und FIRECRAWL_API_KEY werden nicht mehr verwendet.

Was hat sich geändert:

one_scrape und one_map verwenden jetzt agent-browser anstelle von Firecrawl
one_extract bereitet jetzt Seiteninhalte mit mehreren URLs für die nachgelagerte Analyse vor, anstatt eine integrierte LLM-Extraktion durchzuführen
Alle browserbasierten Vorgänge werden jetzt lokal abgewickelt, was für besseren Datenschutz sorgt und keine API-Kosten verursacht

Migrationsschritte:

Chromium-Browser installieren (siehe Voraussetzungen)
FIRECRAWL_API_URL und FIRECRAWL_API_KEY aus Ihren Umgebungsvariablen entfernen
Auf die neueste Version aktualisieren: npm install -g one-search-mcp@latest

Voraussetzungen

Browser-Anforderung: Dieser Server verwendet agent-browser für Web-Scraping und lokale Suche, was einen Chromium-basierten Browser erfordert.

Gute Nachrichten: Der Server erkennt und verwendet automatisch Browser, die bereits auf Ihrem System installiert sind:

✅ Google Chrome
✅ Microsoft Edge
✅ Chromium
✅ Google Chrome Canary

Wenn Sie keinen dieser Browser installiert haben, können Sie:

# Option 1: Install Google Chrome (Recommended)
# Download from: https://www.google.com/chrome/

# Option 2: Install Microsoft Edge
# Download from: https://www.microsoft.com/edge

# Option 3: Install Chromium via agent-browser
npx agent-browser install

# Option 4: Install Chromium directly
# Download from: https://www.chromium.org/getting-involved/download-chromium/

Available Tools

4 tools

one_extractA

Fetch and preprocess page content from one or more URLs. Returns cleaned text blocks that can be passed to downstream tools or models.

ParametersJSON Schema

Name	Required	Description	Default
`urls`	Yes	List of URLs to extract information from

TDQS

A3.5/5.0

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. 'Returns cleaned text blocks' hints at preprocessing but does not detail cleaning steps, error handling, or auth needs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with action, then output. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool (1 param, no output schema), description adequately covers purpose and output. Lacks details on cleaning specifics, error handling, or limits.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers parameter with 100% coverage. Description adds value by specifying preprocessing and output type ('cleaned text blocks'), going beyond schema's 'extract information'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'fetch and preprocess' and the resource 'page content from URLs'. Differentiates from siblings: one_map, one_scrape, one_search.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or when-not-to-use guidance. Mentions downstream use but lacks context for choosing over siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

one_mapA

Discover URLs from a starting point by loading a page in the browser and extracting links from its HTML.

ParametersJSON Schema

Name	Required	Description
`url`	Yes	Starting URL for URL discovery
`limit`	No	Maximum number of URLs to return
`search`	No	Optional search term to filter URLs
`includeSubdomains`	No	Include URLs from subdomains in results

TDQS

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It does disclose the core mechanism—loading a page in the browser and extracting links from its HTML—but it omits important details such as whether the crawl is recursive, whether subdomains are included by default, or any performance/rate implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that immediately conveys the main action and mechanism. It contains no filler, repetition, or unnecessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is minimal but sufficient for a simple one-page link extractor. However, with no output schema, it leaves ambiguity about return format and whether discovery is recursive or limited to the initial page, which is important for a mapping tool with four parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description does not need to add much parameter detail. It simply reinforces 'starting point' for the url parameter and adds no new meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action: discover URLs from a starting point by loading a page in the browser and extracting HTML links. This clearly distinguishes it from sibling tools like one_extract, one_search, and one_scrape, which focus on other tasks.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context that this tool is for mapping/discovering URLs from a starting page, which implies when it should be selected. However, it does not explicitly mention alternatives or state when not to use it, so it falls short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

one_scrapeA

Scrape a single webpage and return markdown, HTML, links, or a screenshot. Supports navigation timeout, TLS verification control, full-page screenshots, bounded pre-scrape actions, and advanced executeJavascript only when allowExecuteJavascript is true.

ParametersJSON Schema

Name	Required	Description
`url`	Yes	The URL to scrape
`actions`	No	List of pre-scrape actions to run before content capture. Standard actions are bounded; executeJavascript requires allowExecuteJavascript: true.
`formats`	No	Content formats to extract (default: ['markdown'])
`timeout`	No	Maximum time in milliseconds to wait for the page to load
`waitFor`	No	Time in milliseconds to wait for dynamic content to load
`skipTlsVerification`	No	Skip TLS certificate verification
`allowExecuteJavascript`	No	Must be true when actions contain executeJavascript. Use only for advanced page-side scripting.

TDQS

A3.7/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It notably discloses support for navigation timeout, TLS verification control, full-page screenshots, bounded pre-scrape actions, and the gating of executeJavascript. It does not mention error behavior or return structure, but these are less critical for a scraping tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise at two sentences, front-loaded with the core purpose, and every clause adds value (outputs, timeout, TLS, screenshots, actions). There is no fluff or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (7 parameters, no output schema, no annotations), the description provides a good overview of capabilities but lacks details on return value structure, error handling, or pagination/navigation behavior. It is adequate but has clear gaps, especially regarding what the returned data looks like for each format.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Since schema description coverage is 100%, the baseline is 3. The description adds some context by mentioning 'bounded pre-scrape actions' and the executeJavascript requirement, which aligns with the actions and allowExecuteJavascript parameters. However, it does not add significant syntax or format details beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool's action ('Scrape a single webpage') and its outputs ('markdown, HTML, links, or a screenshot'), which distinguishes it from the sibling tools by focusing on single-page scraping. It is a specific verb+resource statement, though it does not explicitly contrast with siblings like 'one_extract'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for scraping a single webpage and mentions the prerequisite for executeJavascript ('only when allowExecuteJavascript is true'). However, it does not explicitly state when to choose this tool over alternatives such as one_extract, one_search, or one_map, nor does it provide exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

one_searchB

Search and retrieve content from web pages. Returns SERP results by default (url, title, description).

ParametersJSON Schema

Name	Required	Description
`limit`	No	Maximum number of results to return (default: 10)
`query`	Yes	Search query string
`language`	No	Language code for search results (default: auto)
`timeRange`	No	Time range for search results (default: all)
`categories`	No	Categories to search for (default: general)

TDQS

B3.2/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description states it returns SERP results (url, title, description), which is helpful. However, with no annotations, it lacks details on pagination, rate limits, or blocking behaviors. It adequately covers the basic return value but could be more transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with two sentences, front-loading the purpose. Every sentence adds value with no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the absence of an output schema and the presence of 5 parameters (including enums for categories and timeRange), the description does not fully explain the usage of these parameters or the structure of the response beyond basic SERP fields. It feels incomplete for an agent to use effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema coverage is 100%, so the schema already describes all parameters. The description adds no extra meaning beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches and retrieves content from web pages and returns SERP results with URL, title, and description. It is specific but does not explicitly distinguish itself from sibling tools like one_map or one_scrape.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. No when-not-to-use or prerequisite information is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A3.7/5.0

Scored 2026-07-31 22:35 across 4 tools

Disambiguation4/5

Each tool has a distinct core function: search returns SERP results, extract preprocesses multiple URLs, scrape handles single-page advanced operations, and map discovers links. There is minor overlap between extract and scrape for fetching page content, but their descriptions make the intended use cases clear.

Naming Consistency5/5

All tool names follow the consistent pattern 'one_' prefix followed by a lowercase action verb (search, extract, scrape, map), with underscores between words. No mixed conventions or camelCase.

Tool Count5/5

Four tools is well within the ideal range for a focused search/scraping server. Each tool covers a distinct aspect of web research, making the set feel appropriately scoped without being bloated.

Completeness4/5

The tool set covers the primary workflows: searching, extracting content, single-page scraping with advanced options, and link discovery. Minor gaps exist, such as no dedicated batch scraping tool, but the combined functionality handles most common use cases.
