AnySearch MCP Server

English | 简体中文

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

Features

• General Web Search — open-ended natural language queries
• Vertical Domain Search — structured queries across finance, academic, security, legal, code, and more
• Parallel Batch Search — execute multiple 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.

Register for an API Key (Recommended)

The agent can register the user and obtain an API key in a single call — no verification code, no manual signup. Ask the user for a real email address: it becomes the account username.

curl -s -X POST "https://api.anysearch.com/v1/auth/email/register" \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com"}'

Success response (code: 0) returns the account info and a one-time plaintext API key:

{
  "code": 0,
  "message": "success",
  "data": {
    "username": "you@example.com",
    "email": "you@example.com",
    "login_url": "https://www.anysearch.com/login",
    "api_key": {
      "id": "key_xxxxxxxx",
      "key": "as_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      "key_prefix": "as_sk_xxxxxx...",
      "name": "default",
      "rate_limit": 100,
      "quota_limit": 0,
      "expires_at": null,
      "created_at": "2026-06-23T10:23:00Z"
    }
  }
}

Quota fields such as rate_limit are account-specific response values; do not treat the example as a fixed plan.

On success the agent MUST:

1. Put data.api_key.key into the MCP server config as the Authorization: Bearer <key> value (and/or set ANYSEARCH_API_KEY) — it is shown only once (it can also be retrieved later from the dashboard).
2. Tell the user their username (= email) and the login_url.

Errors can be expressed through the HTTP status, application-level code, or message; do not assume every error uses code: -1:

status / code / message	what to do
Invalid email address.	ask the user to re-enter the email
HTTP 409 or email_already_registered	email is taken — tell the user to sign in at login_url; do not retry
code: 42901, rate_limited, or contains Rate limited	prefer a retry delay from Retry-After, response data, or the message; if none is provided, stop repeated requests and retry later or use anonymous access
starts with Key creation failed.	account created but key failed — extract the email and URL from the message ("Key creation failed. Your account <email> was created; sign in at <url>.") and tell the user to sign in there to create a key manually
Internal server error.	retry later or fall back to anonymous

The email must be real and reachable.
