"Semantic search, RAG, and memory systems" matching MCP servers:

An MCP server for domain name availability checking, WHOIS lookups, and domain suggestions — no API key required.

Enables agents to run SEO and AI-search readiness audits (llms.txt, crawler access, sitemaps, structured data, redirects, indexability, and more), look up startup revenue listings and leaderboards, and check a domain's SPF, DKIM, DMARC, and MX records with concrete fixes. Runs locally over stdio with no account or API key, and frames all third-party responses as untrusted data.

The official remote Model Context Protocol (MCP) server for Muumuu Domain — a domain registration service operated by GMO Pepabo, Inc. Search and register domains, manage owned domains and contracts, and configure DNS records — all through natural language conversations with AI assistants.

MCP server that parses 3GPP .docx specifications into structured sections with full-text search, letting LLMs browse, search, and follow cross-references without a vector database.

Routes web requests through 175M+ residential IPs across 195+ countries, enabling AI to bypass geo-restrictions and anti-bot systems.

Exposes network-monitoring tools (query metrics, analyze windows, compare, logs, status, runbooks, speed tests) as an MCP server for agentic workflows. Designed with evaluation suites, cost-aware model routing, and semantic tool retrieval.

A Model Context Protocol (MCP) server for the RIPE Atlas network measurement platform. Enables AI assistants to create network measurements, retrieve results, search probes, and manage credits.

Analyzes Telerik Fiddler SAZ session archives, enabling AI assistants to inspect, search, and filter HTTP sessions, plus performance and security auditing.

Bridges LLMs with Uyuni infrastructure management, enabling natural language system administration such as inspecting systems, managing updates, and scheduling actions.

Control your UniFi network via AI with a lightweight 2-tool MCP server that supports both cloud and local UniFi controllers.

Provides search and detail tools for YANG paths across network vendor models (Nokia, Cisco, Arista), enabling models to find correct gNMI paths without guessing. The server is offline and does not connect to any devices.

Lets an AI assistant inspect a Linux machine through ten fixed read-only tools covering load, memory, disks, processes, ports, interfaces, systemd units, the journal, and allowlisted log files. All output is size-capped, control-character-stripped and secret-redacted, and nothing in the package can write to the system.

An MCP server for querying the Qianxin Hunter network asset mapping platform, enabling asset search, batch queries, and export tasks.

A minimal MCP server for Shodan, enabling infrastructure reconnaissance through tools like host lookup, search, CVE lookup, and DNS queries.

Enables AI agents to perform passive reconnaissance, vulnerability intelligence, DNS analysis, and device search using Shodan's database of internet-connected devices, all from within your IDE.

A read-only diagnostic server that inspects Linux PTP/Chrony status, PHC hardware-timestamping capabilities, and ROS 2 topic header timestamps to surface clock-domain mismatches, jitter, drift, and alignment problems in robotics systems. It exposes 15 tools and 4 prompts that generate traceable JSON or Markdown reports, running entirely locally over stdio without root access, cloud inference, or any clock modification.

UniFi semantic-analysis MCP — 54 tools on Site Manager API and Cloud Connector. 8 workflow Prompts (4 fleet-ops + 4 MSP). Read-only.

Provides MCP servers for VPN control (NordVPN) and torrent lifecycle management via Jackett search and qBittorrent operations, plus a unified CLI.

Enables AI assistants to read and manage NetBox network infrastructure data via MCP. Supports querying all object types, search, changelogs, GraphQL, IP/prefix/VLAN allocation, cable tracing, config rendering, and write operations with safety modes.

A hosted MCP server that enables AI agents to interact with the Starlink Enterprise API using service accounts, with transparent OAuth token management and 55 auto-generated tools.

AgentDomain MCP allows AI agents to register, buy, and manage internet domains via the Model Context Protocol. Features include domain search, availability check, purchase, DNS record management, and wallet operations.

A read-only MCP server for Peering Manager that exposes BGP sessions, autonomous systems, routers, IXPs, and other peering infrastructure data as conversational tools for Claude and other MCP clients.

Provides access to Shodan's IoT search engine API for device search, host intelligence, exploit database, network scanning, and security analysis through natural language.

MCP server that enables AI agents to search domain, IP, port, service, title, ICP, server header, and component assets via the SCANDOMAIN API using Quake-style DSL queries.

A complete MCP server for the Internet.bs domain registrar API, providing 47 tools for domain management, DNS, transfers, and more.

MCP server for Packmate, a CTF network traffic analyzer, enabling LLMs to analyze network traffic streams, search patterns, and manage pcap files.

MCP server that exposes Shodan API for host information, search, alerts, scanning, and exploit data.

Aggregates multiple cyberspace search engines (FOFA, Quake, Hunter, ZoomEye) into a unified MCP server, enabling asset search, pagination, statistics, and account info retrieval.

Geekflare MCP server connects your AI agents to the live web for scraping, search, screenshots, DNS lookup, site uptime and more.

Enables AI clients to drive the full Remnawave panel API, exposing one tool per method+path operation (users, nodes, hosts, subscriptions, inbound, bulk actions) plus search, describe, status, audit and metrics helpers. Read-only/read-write gating, deny rules, confirm-preview and dry-run, response secret redaction and an audit journal keep mutations controlled.
