"Answer" matching MCP servers:

Enables users to ask buyer questions across Google AI Overviews, ChatGPT, Claude, Perplexity, and Gemini and receive sampled answer rows, brand named/cited rates, competitor rates, and cited sources. Runs the tracking workflow on Apify and returns dataset rows ready for analysis.

Enables AI agents to query China's GB/T 47746—2026 customer-service compliance standard, providing clause-referenced answers, self-check lists, and standard metadata via MCP tools.

Enables agents to query China's GB/T 47746—2026 AI customer-service compliance standard through five clause-level tools — question listing, keyword search, full cited answers, enterprise self-check lists, and standard metadata — over a public read-only streamable-http endpoint with no API key required. Answers include clause sources so compliance questions like mandatory human-handoff scenarios can be resolved without manually paging through the 40-page standard.

Enables AI agents to search layered web and about 45 structured data sources and receive quote-checked answers with supporting citations, or not_found when the evidence is insufficient.

Enables finding information online, reading web pages, finding images, capturing screenshots, and performing multi-source research with per-answer confidence.

Source-backed hardware end-of-life (EOL/EOSL) lookups by part number for enterprise gear — support status, end-of-sale and end-of-support dates, with the vendor's own bulletin URL on every answer. Unknown parts return found:false, never a guess.

Search, filter, and sample over a million competition and olympiad math problems (AMC, AIME, IMO, Putnam, MATH, Omni-MATH) by topic, contest, year, and difficulty, and fetch any problem's LaTeX statement with its answer, hints, and solutions where available.

Lets an AI agent ask its owner first, on their phone, before doing something irreversible: ask_approval blocks until a person answers and distinguishes DENIED from NO ANSWER, so a timeout is never read as consent. send_notification covers one-way alerts with priorities and quiet hours.

MCP server exposing memory search, index, and stats tools for agents, with honesty guards to prevent re-litigation of settled decisions.

Enables AI assistants to answer questions about livestream advertising using GingerLive's up-to-date data on ad formats, network reach, campaign case studies, and the streamer program, as well as plan campaigns and evaluate streamer monetization.

Verifies factual claims against live sources and returns a verdict, confidence score, and citations for any agent to use before stating uncertain facts.

Stop hallucinating numbers. An MCP server that runs every math expression through four independent numeric engines in parallel and returns all four results side by side — so when they disagree, you know the answer is numerically unreliable.

Index docs websites and local folders, then let Claude, Cursor, or any MCP client answer from the current docs, with a link to every section it used.

Long-term memory for Claude Desktop and Claude Code over plain markdown files on your machine. It returns nothing when the corpus has no answer, naming the terms that appear nowhere — no least-bad match dressed as an answer. And it verifies cited commit SHAs against git, so an agent can tell what actually shipped from what was only discussed and abandoned. Local; nothing is transmitted.

Any Norwegian company's revenue, profit, debt and who sits on its board, which companies are going bankrupt, who owns what through group structures, plus house prices, mortgage rates, wages and inflation straight from Statistics Norway. Official registers, no API keys, every answer cites its source.

Read-only, masked views of a local US tax workspace: the documents, each form's checks and the to-do list. Every answer is masked (digits and names hidden), so a cloud agent never sees an amount, name or account number.

Checks whether a project name is free across package registries, app stores, agent and editor plugin directories, GitHub, and domains, applying each registry's own rules for similar, reserved, alias, and recently deleted names. Reports the evidence and confidence behind every answer so agents can distinguish available names (or probably available ones) from taken, unavailable, or unknown results.

Two AIs. One answer. ChatGPT and Claude discuss with each other until they agree, through your own signed-in CLIs: no API keys. Both read your project (never change it) and search the web. Plugin for Claude Code, Codex, Claude Desktop and the ChatGPT app.

Checks what GPTBot, ClaudeBot, PerplexityBot and 50+ other AI crawlers can read on a site and what its access policy allows, checks whether a page permits search, answers, training or agent use (with a signed receipt), generates llms.txt, robots.txt and JSON-LD, and reads your Answer Analysis. Nine tools for Claude Desktop, Cursor and other MCP clients.

Get a second opinion on your code from every coding agent you have. Claude Code, Codex and Grok review each other's diffs and answer each other's questions, even inside a session that's already running. Uses the CLIs you're signed in to, no API keys.
