"A memory-efficient MCP server with vectorized memory bank synchronization" matching MCP servers:

Hermetic memory for AI agents — one Rust binary, one SQLite file, zero network. Recall returns evidence with provenance or abstains: no code path for making things up.

Cite-able, content-addressed, signed memory of every place on Earth

This MCP server enables AI agents to perform exploratory UI testing of live web apps by providing a structured view of page elements, deterministic correctness oracles, enforced read-only or opt-in write policies, persistent cross-run memory, and gap-checked coverage reports.

Enables AI agents to read, write, search, and manage .klypix canvas files for persistent spatial memory across sessions.

Enables transferring conversation context between different AI chats or projects with automatic server discovery and memory-based storage. Supports saving, loading, and managing conversation histories in a human-readable Markdown format.

Persistent project context (AGENTS.md), cross-session memory, and identity — discoverable by any MCP client.

Social layer for AI coding — DMs, presence, discovery, and multiplayer games between developers. 68 tools including messaging, presence, memory, and 27 multiplayer games.

Query bank accounts, credit cards, and transactions via Sophtron's financial data API. Works with Claude Desktop and any MCP-compatible client.

An MCP server for TouchDesigner that lets AI agents inspect, build, wire, optimize, and stabilize live TD networks with 106 tools, plus a technique memory system for reusable patterns.

Multi-agent shared brain MCP server enabling cross-session memory, self-improving skill loops, and inter-agent signaling across Claude, Codex, Gemini, Copilot, and VS Code CLI agents.

Deterministic state layer for AI agents that stores versioned entities such as contacts, tasks, transactions, and decisions with immutable observations and full provenance. Local-first SQLite memory shared across Claude, Cursor, ChatGPT, Codex, and OpenClaw via MCP and native plugins.

Enables real-time domain registration lookups via RDAP, including availability, expiration, and registrar details, with no API key required. Supports natural language queries like 'is example.com available?' or 'when does example.com expire?'.

Enables AI assistants to bulk-check hundreds of brainstormed domain names in a single call, reporting which are available, taken, or reserved along with buy links and prices from multiple registrars. It runs locally via DNS, RDAP, and WHOIS lookups, with optional registrar API keys for confirming availability and premium pricing.

Embeds live, interactive Tableau dashboards in ChatGPT, pushing mark selections to the model so questions about specific data points are answered with live queried numbers.

MCP server that lets agents create, display, and export rich UI widgets (cards, dashboards, charts, forms) inline in conversations, with interactive iframe support in MCP Apps hosts and PNG image fallback for other clients.

Vacation rental software. A signed stay offer on the host's own domain. Agents discover a host domain, verify an Ed25519-signed offer (VRP), and send the guest to that domain to book and pay the host. Do not compare hosts or prices. HemmaBo + VRP, 6 runtime tools: 2 HemmaBo tools, 2 host onboarding tools, and 2 VRP verification tools. Not an OTA. Not a marketplace.

Local-first crypto portfolio aggregation across exchanges (Bybit, Binance), EVM and Solana wallets, and Polymarket. Read-only credentials, runs as a local MCP server. Data aggregation only, not financial advice.

Provides real, official public holiday data for ~100 countries with tools to list holidays for a year and check if a specific date is a holiday. Free, no API key required, powered by Nager.Date.

A demo MCP server that returns an interactive dashboard (bar chart with dataset selector) as an MCP App via the official MCP Apps extension (SEP-1865).

Provides real-time air quality data (US AQI, PM2.5, PM10, ozone, NO2, SO2, CO) for any city via natural language, using free Open-Meteo data and a single tool.
