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.

Federated search of books and papers, BibTeX/RIS citations, open-access retrieval and reading.
Ask questions about Claude Code, Cursor, Codex and MCP — get answers grounded in their official docs, with citations. A hybrid RAG service that AI agents call through two MCP tools (or over REST). It indexes ~600 pages of official documentation, refreshes itself daily, and every design choice is backed by an experiment.
Entity resolution — data mapping, SDK code generation, docs search, and error troubleshooting
Semantic retrieval across 292,000+ Indonesian regulations and 5.4M+ legal provisions, updated daily. Give AI direct access to Indonesian regulatory knowledge before reasoning.
XMemo is a user-owned Memory OS for AI agents, providing a shared, persistent memory layer across AI assistants, IDEs, CLIs, tools, projects, and sessions. It enables ChatGPT, Claude, Codex, Cursor, Gemini, and other supported AI clients to access authorized long-term context without requiring users to repeatedly explain their preferences, project decisions, or previous work. Beyond basic memory storage and retrieval, XMemo supports semantic search, contextual recall, memory updates and corrections, source attribution, version history, project-scoped context, task tracking, and governed memory lifecycle management. Identity-aware access controls, scoped authorization, and memory isolation help users manage which agents and workflows can access their information. XMemo also provides advanced capabilities for structured knowledge, reusable procedures, and memory consolidation through its broader Memory OS platform. Connect through hosted MCP with OAuth or bearer-token authentication, or integrate directly through REST APIs and supported client tools. Memory remains available across authorized clients and sessions, with user-controlled access, export, and deletion. Website: https://xmemo.dev Documentation: https://xmemo.dev/docs
Review supplied AI claims and source excerpts for quote mismatches, broken references and evidence gaps. MCP-native free_trial_status/free_trial: five attempts per network for the campaign, shared daily capacity. Paid checks are separate. No live retrieval or factual-truth certification; human review required.
VAR2 is a hosted creative MCP server for generating and editing images, creating videos, music, voiceovers and 3D assets, and assembling creative workflows. Connect with OAuth using a VAR2 account; generation uses account credits.
Secureship MCP gives AI assistants access to a multi-carrier shipping API covering rate comparison, label generation, package tracking, pickup scheduling, address book management, shipment history, customs documents, and more — across carriers like UPS, FedEx, Purolator, Canpar, and others.

Tools for learning path, coaching context, and handoffs require a Firebase Bearer token. Validation and usage summary tools require a Pro or Teams membership.
MCP server for GOV.UK — search, content retrieval, organisation lookup, and postcode resolution.
Access Zain Ahmed’s public engineering profile, project case studies, technical articles, and platform engineering resources through MCP tools and structured resources. Hosted Streamable HTTP endpoint at zainahmed.net; public retrieval requires no API key.
Read-only directory of vetted AI implementation agencies from the Ashton & Forge marketplace. Search supply by service cluster, industry, client size, engagement stage, or budget; get_matched returns the brief link for up to three human-verified introductions.
The AI-native video editing OS — timeline editing, color, audio, captions, generation (image/video/voice/music/SFX), review/share, and export — as MCP tools over your Arsaze account.
AI video editor for agents and humans: timeline, captions, color, audio and generation as MCP tools.
CUQU (找搭子) is a local offline social activities platform in China (Shenzhen-based, 10+ cities). Its MCP gateway exposes 8 tools: activity search, event booking, payment, check-in, organizer event creation, venue search, and share-link generation, covering 100+ activity categories (board games, frisbee, hiking, badminton, fishing, anime and more).
Your agent needs to find video — which channels own a topic, which videos rank for a phrase, what exists in a given country and language. **What you can ask for** • "Which videos rank for 'rag pipeline tutorial' in the US this month?" • "Find channels publishing about MCP, sorted by relevance." • "What playlists cover this subject in Japanese?" • "Search videos uploaded this week only." **How to use it** Point any MCP client at https://mcp.aisa.one/youtube-search/mcp and sign in with OAuth — there is no key to create or paste. One search tool covering videos, channels and playlists, narrowed by country, language, upload date, duration and sort order. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the video here, then ask the same agent what the channel's site traffic is or what the same phrase does in Google — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/social/mcp for X plus Instagram, Reddit, Pinterest and YouTube; https://mcp.aisa.one/gtm/mcp for those plus Similarweb and Apollo.
Magic Hour MCP lets AI agents create and edit images, videos, and audio using Magic Hour’s hosted generation tools.
Generate contextual prompts and reusable agent skills, evaluate prompts with the 16-dimension Prompt Score, and manage saved work in PromptDrive. Twelve MCP tools also provide authorized access to private Memory for source-grounded answers. Connect over Streamable HTTP using OAuth 2.1 and PKCE. Generation consumes account quota and automatically saves successful results; Memory access follows account permissions and plan limits.
