AnySearch MCP Server

Unified real-time search MCP server supporting general web search, vertical domain search (23 domains), parallel batch search, and full-page URL content extraction.

Features

• General Web Search — open-ended natural language queries
• Vertical Domain Search — structured queries across 23 domains (finance, academic, security, legal, code, etc.)
• Parallel Batch Search — up to 5 independent queries in one call
• URL Content Extraction — fetch and extract full page content as Markdown
• Anonymous Access — works without an API key (with lower rate limits)

API Key Configuration

An API key is optional but recommended. Without a key, all features still work via anonymous access with lower rate limits.

Get an API Key

Visit https://anysearch.com/console/api-keys to create a free API key.

Key Priority

Priority	Source
1 (highest)	--api_key CLI flag / Authorization header
2	Environment variable ANYSEARCH_API_KEY
3	.env file (ANYSEARCH_API_KEY=<key>)
4	Anonymous access (lower rate limits)

Key Behavior

Scenario	Behavior
No key	Proceed with anonymous access (lower rate limits)
Has key	Sent via Authorization: Bearer <key> header, higher rate limits
Key exhausted, auto-registered key returned	Agent should ask user for confirmation, then persist the new key
Key exhausted, no new key	Inform user and suggest configuring a new API key

MCP Transport

AnySearch MCP server natively supports Streamable HTTP transport (MCP spec 2025-03-26). SSE and stdio clients can connect via proxy.

Transport	Native?	Best for
Streamable HTTP	Yes	OpenCode, Claude Desktop (2025.6+), web-based clients
SSE	Via proxy	Cursor, Windsurf
stdio	Via proxy	Claude Desktop (legacy), VS Code Copilot, Cline

Installation

Streamable HTTP (Recommended — No Proxy Needed)

For agents that support the Streamable HTTP transport (MCP spec 2025-03-26+):

OpenCode (~/.opencode/config.json or project opencode.json):

{
  "mcp": {
    "anysearch": {
      "type": "streamable-http",
      "url": "https://api.anysearch.com/mcp",
      "headers": {
        "Authorization": "Bearer ${ANYSEARCH_API_KEY}"
      }
    }
  }
}

Claude Desktop (2025.6+, claude_desktop_config.json):

{
  "mcpServers": {
    "anysearch": {
      "type": "streamable-http",
      "url": "https://api.anysearch.com/mcp",
      "headers": {
        "Authorization": "Bearer ${ANYSEARCH_API_KEY}"
      }
    }
  }
}

Without an API key, omit the headers section. The server will use anonymous access automatically.

stdio (Via Proxy)

For agents that only support stdio transport. Two proxy options:

Option A: mcp-remote (Recommended)

mcp-remote — auto-detects Streamable HTTP, simplest config:

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "anysearch": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.anysearch.com/mcp",
        "--header",
        "Authorization: Bearer ${ANYSEARCH_API_KEY}"
      ]
    }
  }
}

VS Code Copilot (.vscode/mcp.json):

{
  "servers": {
    "anysearch": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.anysearch.com/mcp",
        "--header",
        "Authorization: Bearer ${ANYSEARCH_API_KEY}"
      ]
    }
  }
}

Cline (VS Code settings):

{
  "mcpServers": {
    "anysearch": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.anysearch.com/mcp",
        "--header",
        "Authorization: Bearer ${ANYSEARCH_API_KEY}"
      ]
    }
  }
}

Without an API key, omit the "--header" and "Authorization: Bearer ..." args.

Option B: supergateway

supergateway — more transport options, supports SSE output:

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "anysearch": {
      "command": "npx",
      "args": [
        "-y",
        "supergateway",
        "--streamableHttp",
        "https://api.anysearch.com/mcp",
        "--oauth2Bearer",
        "${ANYSEARCH_API_KEY}"
      ]
    }
  }
}

Without an API key, omit the "--oauth2Bearer" and key args.

SSE (Via Proxy)

For agents that only support SSE transport (Cursor, Windsurf). Requires running a local SSE proxy server:

Start the proxy

npx -y supergateway \
  --streamableHttp https://api.anysearch.com/mcp \
  --outputTransport sse \
  --port 8000 \
  --oauth2Bearer <your_api_key>

Without an API key, omit the --oauth2Bearer flag.

Then configure your agent:

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "anysearch": {
      "type": "sse",
      "url": "http://localhost:8000/sse"
    }
  }
}

Windsurf (~/.codeium/windsurf/mcp_config.json):

{
  "mcpServers": {
    "anysearch": {
      "serverUrl": "http://localhost:8000/sse"
    }
  }
}

The SSE proxy must remain running while the agent is active. Consider running it as a background service.

Available Tools

search

Execute a search query — general or vertical domain.

Parameter	Type	Required	Description
query	string	Yes	Search query. For vertical search, follow the query_format from list_domains
domain	string	No	Vertical domain (e.g. finance, academic, security)
sub_domain	string	No	Sub-domain routing key (e.g. finance.us_stock). Required for vertical search
sub_domain_params	object	No	Extra params per sub_domain schema
content_types	string[]	No	Filter: web, news, code, doc, academic, data, image, video, audio
zone	string	No	cn or intl. Required when sub_domain marks zone=CN
max_results	integer	No	1–100, default 10
freshness	string	No	day, week, month, year

list_domains

Query the vertical domain directory. Must be called before vertical search to discover available sub_domains and their query formats.

Parameter	Type	Required	Description
domain	string	One of	Single domain to query
domains	string[]	One of	Batch up to 5 domains

Returns a Markdown table: sub_domain | description | query_format | params_schema | zone

batch_search

Execute 2–5 independent search queries in parallel. Single failure does not block others.

Parameter	Type	Required	Description
queries	object[]	Yes	1–5 query objects, each with same fields as search

extract

Fetch full page content from a URL and return as Markdown. Truncated at 50,000 characters. HTML pages only.

Parameter	Type	Required	Description
url	string	Yes	Target URL (http:// or https://)

Decision Flow

User query
  |
  +-- Has structured identifiers? (Stock:/CVE:/DOI:/IATA:/patent etc.)
  |     YES -> 1) list_domains -> discover sub_domain & query_format
  |             2) search with domain + sub_domain + zone
  |
  +-- Multiple independent intents?
  |     YES -> batch_search
  |
  +-- Need deeper content than snippets?
  |     YES -> extract the URL
  |
  +-- Otherwise -> search (general)

Vertical Search Constraints

Before vertical search, you must call list_domains for the target domain and follow:

1. query_format — exact format for the query string (e.g. raw ticker, not natural language)
2. params_schema — JSON schema for optional extra parameters
3. zone — if CN, you must set zone: "cn" in the search call
4. sub_domain selection — match user intent to the best sub_domain description

Supported Domains

Examples

General search

{ "query": "quantum computing breakthroughs 2025", "max_results": 5, "freshness": "month" }

Vertical search (stock)

{ "query": "AAPL", "domain": "finance", "sub_domain": "finance.us_stock", "max_results": 5 }

Batch search

{
  "queries": [
    { "query": "AAPL", "domain": "finance", "sub_domain": "finance.us_stock" },
    { "query": "python async http client", "domain": "code", "sub_domain": "code.general" }
  ]
}

Extract URL

Security Notes

• Search queries, extracted URLs, and API keys are sent to https://api.anysearch.com
• Do not use for queries containing sensitive information (passwords, personal data, trade secrets) unless you trust the provider
• Avoid pasting API keys directly in chat — use environment variables or .env files
