Enables free-first English and Chinese web search through zero-key engines plus optional paid providers, returning compact multi-source evidence with bounded token and request budgets. Each result exposes provenance, independent source counts, routing decisions, and visible provider failures so agents can verify claims rather than receive unexplained empty results.

Enables English and Chinese web search without API keys by aggregating zero-key and optional paid providers, with compact multi-source evidence, visible provider failures, and bounded request/evidence budgets. Supports quick discovery, stricter verification, Chinese-source search, and URL extraction.

Enables free-first English and Chinese web search without API keys, returning compact multi-source evidence with visible provider failures and bounded request/evidence budgets. Optional paid providers can run only under explicit policy and credentials.

Enables English and Chinese web search that works without an API key by routing across zero-key engines, with optional paid providers used only under an explicit policy. Returns compact multi-source evidence with provenance, source-family counts, stop reasons, and visible provider failures, all bounded by request and evidence budgets.

Enables free-first English and Chinese web search without any API key, returning compact multi-source evidence that preserves provenance, source-family counts, and visible provider failures. Request and evidence budgets bound each query, while optional paid providers run only when an explicit routing policy and credentials allow.

Enables agents to perform free-first English and Chinese web searches without requiring API keys, returning compact multi-source evidence with provenance, bounded request/evidence budgets, and visible provider failures. It also supports optional paid providers under routing policy, Chinese-source search, and URL extraction.

Enables English and Chinese web search without an API key, returning compact multi-source evidence while recording provider failures and enforcing request and evidence budgets. Paid providers can be used only when policy and credentials allow.

Enables English and Chinese web search starting without any API key, aggregating zero-key and optional paid providers into compact, multi-source evidence packets. Exposes provenance, provider families, partial failures, stop reasons, and request/evidence budgets so agents can verify results and control cost and token usage.

Enables English and Chinese web search and URL extraction through zero-key sources with no API account required, returning compact multi-source evidence with provenance, visible provider failures, and bounded request and token budgets. Paid providers are used only when routing policy and credentials explicitly allow it.

Enables keyless English and Chinese web search across multiple engines, with optional paid providers governed by routing policy. Returns compact, budget-bounded evidence that preserves provenance, quality-gate stop reasons, and visible partial failures for verification.

Enables English and Chinese web search starting from zero-key sources, returning compact multi-source evidence with provenance and visible provider failures. Requests and output stay bounded by configurable result, time, and evidence budgets, with paid providers used only when policy and credentials allow.

Free multi-source web search server for AI agents, with confidence scoring and token optimization.

An MCP server that enables Claude Code to perform web searches via Bing, read webpage content, and get current time, with a smart search skill for structured multi-source verification.

Enables agents to run free-first English and Chinese web searches without API keys, returning compact multi-source evidence with visible provider failures and bounded request and evidence budgets. Optional paid providers can be used under routing policy when configured.

Enables AI agents to run English and Chinese web searches without any API key, returning compact multi-source evidence with provenance and preserving provider failures in the response. It also caps adapter attempts, elapsed time, and response tokens, and can optionally escalate to paid providers under an explicit routing policy.

Enables AI agents to run English and Chinese web searches without an API key, combining zero-key engines with optional paid providers and returning compact, provenance-tagged evidence under request and token budgets. Provider failures stay visible instead of being silently dropped, and additional tools extract URLs, GitHub READMEs, and Chinese technical articles.

Enables AI agents to run English and Chinese web searches that work without an API key, returning compact multi-source evidence with visible provider failures and bounded request and evidence budgets. Also supports extracting URLs and fetching pages such as GitHub READMEs and Chinese technical articles as clean Markdown.

A model context protocol server designed for AI development and QA, providing AntV document context and code examples.

Enables SDK and MCP clients to perform repository code search and retrieval, inspect current source and related evidence, and optionally use semantic search, reranking, and web sources while keeping the calling agent in control.

Enables AI agents to perform web search, extraction, and research across multiple provider backends with persistent multi-key rotation and auditable routing. Supports MCP, CLI, and Agent Skill entry points.

Provides real-time Google search capabilities to AI assistants like Claude, bypassing anti-scraping mechanisms.

Screens AI agent tool calls before execution and tool results before the agent reads them, acting as an MCP proxy and hooks adapter with shadow, enforce, and strict policy modes.

Automatically extracts technical concepts from AI coding conversations, organizes them into a searchable knowledge base with hierarchy and categories, and links them to specific locations in your codebase.

Enables AI assistants to perform Google searches with real, resolvable sources and transparent search terms.
