Enables free-first English and Chinese web search through zero-key sources with optional credentialed providers, returning compact multi-source evidence, visible provider failures, and bounded request/evidence budgets.

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 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.

Enables MCP-compatible agents to perform web searches via the agent-web-search engine, returning ranked results with sources.

Enables MCP agents to perform native X (Twitter) searches with original-post citations and transparent usage tracking. Supports existing Grok login sessions or explicit xAI API billing without runtime dependencies.

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

Enables turning a research topic keyword or OpenAlex topic ID into ranked institutions and authors, including identifiers, citation metrics, h-index, and newest papers, with optional filters for year, country, and institution type. It runs the analysis on Apify and returns dataset rows to MCP clients.

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.

Self-hosted web search and page extraction for AI agents. Stdio MCP server, HTTP API and Python/npm CLI.

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 English and Chinese web search that starts working with zero API keys, returning compact multi-source evidence with provenance, visible provider failures, and bounded request and evidence budgets. Optional paid providers run only when routing policy and credentials allow, and results can be fetched as clean Markdown from supported sources.

Enables English and Chinese web search through zero-key sources, plus optional paid providers under an explicit routing policy, without requiring an API account to start. Returns compact multi-source results that preserve provenance, provider failures, and bounded evidence budgets so agents can inspect how each result was found.

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 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.
