Paid web research, fact-check, page summary and page extraction tools for AI agents. Pay per call in USDC with x402 (Base or Solana). A failed call is not charged.
Search Fragments — two tools for the queries an agent can't place, both built to decline rather than guess. resolve_fragment takes a half-remembered, cross-source query ("a musician who became famous for stopping performing") and returns a grounded answer, ranked web sources to confirm by eye, or an explicit no-resolution. verify_claim takes a specific factual assertion and returns supported, partially_supported, insufficient_evidence, or unsupported, with cited evidence and a stated_limits field that is always present. There is no confidence score — insufficient_evidence fires freely, and unsupported requires a source that explicitly contradicts, never mere absence of confirmation. Every verdict is decide-by-eye: "supported" means current web sources confirm it, not that the claim is true. Calibrated against 18 known claims before release. Free, no signup. Streamable HTTP (MCP 2025-11-25). Read-only.
Execute supported agent tasks through verified providers with fallback and durable outcomes.

Engram is a persistent, long-term memory layer for AI agents and assistants. Claude, ChatGPT, Grok, Cursor and any MCP client share one memory, stored as plain markdown notes: your knowledge base, second brain and AI context in one place. No extraction step: the memory is the note itself, so you can read exactly what your AI remembers and fix it. Edit your memory in Obsidian (real-time sync), the web app, or on your phone. Hybrid keyword + semantic search (RAG over your notes) finds exact strings like error messages, config keys and IDs. Remote MCP server over Streamable HTTP with OAuth 2.1; notes encrypted at rest.

Read-only discovery and bounded access to a finite market briefing with evidence boundaries.
SEO and AI-search audit for websites, built for Uzbekistan (Uzbek and Russian sites). Checks on-page SEO, technical health (HTTPS, TLS 1.3, HSTS, HTTP/2-3, robots.txt, sitemap, broken links), AI-search readiness (GEO/AEO), speed and Core Web Vitals, content and social tags, and returns concrete fixes plus AI recommendations for title, description and H1 based on real search demand in Uzbekistan. Start an audit with start_audit, then fetch the result with get_audit.
Give your AI a network of real people. Marcel is an MCP server that lets your AI find and connect you with people who can help. Connect Marcel to Claude, ChatGPT, Codex, Cursor, or another MCP-compatible AI and ask things like: “Who can help me with B2B SaaS distribution?” “Find someone who has hired a customer success team.” “Do I have any new connection requests?” Marcel uses your profile and network to find relevant people and explain why an introduction makes sense. No social feed. No f
Collective memory and evidence-backed trust for AI agents. Search reusable knowledge with search_memories, then inspect_memory to review provenance, reported outcomes and limitations before applying it. Discover public agents and inspect Trust Passports. Public reads require no account or credentials. This Streamable HTTP connector exposes public discovery and existing Candy sandbox tools; Candy participation uses a temporary bearer token and grants no canonical reputation or verified identity. Persistent Agent contributions use a separate authenticated connection described at https://remnant.dedale-bi.com/connect. Remote MCP: https://remnant.dedale-bi.com/mcp. Documentation: https://remnant.dedale-bi.com/connect. Examples: https://github.com/Dedale-Project/remnant-connect. Evidence and cryptographic integrity do not guarantee truth or safety. Bootstrap memories are operator-published, not independently validated.

OPX is a buyer-side routing layer for x402 machine commerce. Before an agent pays a downstream provider, OPX ranks currently tested x402 services using recent paid performance evidence including success rate, latency, price, freshness and task fit, then returns the best provider plus independent fallbacks. Each routing decision costs $0.002 USDC on Base.

Connect LLM tools to your Algolia account with user-scoped access for internal workflows.
Real-time Google Flights fares for agents. Three things people do with this server. Scan for deals: one call takes a date range and a list of destination airports, expands every combination server side, and returns each fare with Google's own low, typical or high verdict. Put live search in your app: flat JSON with a bookable link on every result, and round trips priced as paired legs. Run a 24/7 AI travel agent: add the server, sign in with Google, and schedule it. No ads, no sponsored content. You bring your own RapidAPI key, so every search is billed to your plan and never to anyone else's. Add https://flights.flightpowers.com/mcp , click Sign in, sign in with Google, and paste your RapidAPI key once on the page that opens. Scripts and clients without a sign-in button send the key as x-rapidapi-key on the same URL.
Now part of GAIP Witness: tests supplier claims and compares them with published metadata.
Evidence-first registry of real-world APIs for AI agents, with verified metadata and comparison.
Read-only flight fares for AI assistants: the cheapest fares a2bflight has seen on thousands of routes, one-way and round trip, each with the day it was seen. Three tools, no auth, no key.
AMZScout Skill + MCP gives AI agents live access to real Amazon marketplace data across 14 Amazon marketplaces. Analyze any ASIN, validate product ideas, research niches, compare competitors, discover profitable keywords, and build data-driven PPC strategies using trusted Amazon insights instead of AI assumptions. Works with Claude, ChatGPT, Cursor, and any other MCP-compatible AI client. To connect, you'll need an AMZScout API plan and authorize your account.

A second opinion before your agent acts on one model's unearned confidence. One question goes to 3-4 different AI models that answer independently, then a chair returns a single verdict with a confidence score, the consensus and the dissent that held. A grounded tier buys evidence first (honeypot simulation, OFAC sanctions screen, page content, SEC profile, web results) and itemises what it spent. Pay-per-call with x402 in USDC on Base: no account, no API key, one free call a day.
