Agentic Finance: 500+ agent tools, multi-chain USDC over x402 or MPP, or free via proof-of-work
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.

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.
App Store Optimization data for AI agents: keyword ranks, scores, competitors, charts
B2B company, people and email enrichment with cited sources, built for GCC and MENA companies.
All public upAPI operations as MCP tools: web scraping, search, screenshots, PDF, OCR and more.
Web pages to Markdown, metadata and small crawls for agents. Free daily calls, then USDC x402/MPP.
Fetch any web page as text, markdown, HTML or a screenshot — JavaScript, CAPTCHAs and anti-bot blocking handled — and extract structured data; JSON tools for Google, Amazon, Walmart, YouTube, ChatGPT and Gemini.
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.
70+ pay-per-call tools for AI agents: web search, email verify, KYC, stocks, crypto, news, data
Send a prompt to ChatGPT anonymously and get the answer with its web sources, as JSON.
Read reusable technical experience from other AI agents. Search a real problem with search_memories, then inspect_memory for provenance, evidence, reported outcomes and limitations. Seven anonymous read-only tools also support public agent discovery and Trust Passport inspection/verification. No account or credentials; no publishing, feedback or Candy actions on this endpoint. Operational telemetry may be recorded, but /mcp/chatgpt does not store search query text. Confidence and cryptographic integrity are not proof of truth, safety or independent validation. Writing requires the separate Remnant Agent OAuth connection at https://remnant.dedale-bi.com/mcp/agent-connect. Documentation: https://remnant.dedale-bi.com/connect. Apache-2.0 integration code and examples: https://github.com/Dedale-Project/remnant-connect. The hosted service, backend and knowledge are governed separately.
Paid claim verification with cited web evidence, source provenance, snapshots, and hashes.
67 pay-per-call agent tools via x402: web, crypto, research, docs, charts, compliance
Hosted MCP: 3475 structured web-data tools across 468 platform groups.
Search products and stores in local physical shops. Find availability, prices, and store locations. Currently focused on hardware stores in Spain.
Web scraping for agents. Point it at a URL and it returns the page as clean markdown, JavaScript-rendered pages included. Point it at a site and it maps the URLs or crawls the section you need in the background, a few pages at a time so results fit in the conversation. Search the web and read full pages, extract fields with a JSON schema you define (validated, never invented), read a store's catalogue or a blog's posts from the platform's own feed, and check whether a page has changed. Failed requests cost nothing. The free plan includes 1,500 credits a month.
Web research across search, Reddit, YouTube, local businesses, reviews, ad libraries and more. Every answer carries line-numbered citations; up to 1,000 rows per call without loading them into context.
NordicContacts provides read-only company and decision-maker data for Finland, Sweden and Estonia through a hosted MCP server. Identify companies, count matching segments and retrieve company or contact records for B2B prospecting. Connect to https://nordiccontacts.eu/mcp using Streamable HTTP. You need a NordicContacts account with an active trial or subscription. Sign in and approve access through OAuth. For clients without OAuth support, create an API token in your NordicContacts account and configure Bearer authentication; do not share the token in a chat or public listing. Eligible new accounts receive a one-month trial with 50 shared usage units and no credit card requirement. Starter costs €49/month with 500 included units; Pro costs €79/month with 1,000 included units. Paid prices exclude VAT; applicable VAT is calculated at checkout. The trial is not a recurring free allowance. Service information, taxonomy discovery and segment-count tools do not consume balance. Record-retrieval tools, including company identification, consume the same balance as REST API retrieval and subscribed Excel exports: included units first, then prepaid top-ups. Completed retrieval calls have a one-unit minimum, including calls with no match. Exact charging is documented per tool; do not treat every MCP call as one contact. The MCP server does not create Excel files, send outreach or update CRM records. Excel downloads and Pro's HubSpot/Pipedrive integrations are separate web-application workflows. A one-time Excel purchase alone does not grant MCP access. Setup and tool reference: https://nordiccontacts.eu/agents/docs
