Endpoint, auth type and tool list, checked by connecting on 4 November 2026. Source: https://agentmcpdirectory.com/directory/nslookup-io Site: Agent MCP Directory Last reviewed: 2026-11-05 # Nslookup: MCP server, CLI and agent surfaces Yes: Nslookup runs a public MCP server at mcp.nslookup.io that listed 23 tools to a client with no credentials on 4 November 2026. Examples: dns\_lookup, dns\_record, dns\_propagation. It speaks streamable-http, protocol 2025-11-25. Open servers are readable by any agent; writes still depend on each tool. ## Fact sheet | Company | Nslookup (registry title: Venomseven Nslookup) | | --- | --- | | Domain | nslookup.io | | Category | Uncategorised (assigned by this directory from the registry description) | | MCP server | Verified (No authentication) | | Ora score | none: Ora returned no cached score for nslookup.io when asked on 5 November 2026 | | Company found through | the GitHub MCP Registry | | Last verified | 4 November 2026 | ## MCP server | Endpoint | https://mcp.nslookup.io/mcp | | --- | --- | | How it was found | listed in the GitHub MCP Registry | | Transport | streamable-http | | HTTP status | 200 | | Protocol version | 2025-11-25 | | Server | nslookup 1.6.0 | | Capabilities | tools | | Tools | 23 | | Resources | 0 | | Prompts | 0 | | Connected | 4 November 2026, 20:03 UTC | | Handshake time | 554 ms over 1 attempt | ### Tools listed 23 tools - dns\_lookup - dns\_record - dns\_propagation - webservers - ssl\_certificate - bimi\_vmc - security\_scan - uptime\_check - uptime\_check\_multi - dns\_health - geo\_checker - rdap\_lookup - hosting\_report - domain\_scanner - dns\_change\_review - bimi\_check - status\_page - my\_overview - my\_monitors - my\_incidents - my\_uptime\_history - my\_dns\_changes - my\_certificates ### Connector log 2 connections on 4 November 2026, read-only methods only - 19:58:34Z https://mcp.nslookup.io/mcp sent initialize, notifications/initialized, tools/list result verified (HTTP 200) 655 ms - 20:03:47Z https://mcp.nslookup.io/mcp sent initialize, notifications/initialized, tools/list result verified (HTTP 200) 554 ms ## Authentication | Auth type | No authentication | | --- | --- | ### The sign-in route, step by step 1. Send the handshake to `https://mcp.nslookup.io/mcp` over streamable-http. Servers on the 2026-07-28 revision answer `server/discover`; older servers answer `initialize`. 2. Send `tools/list`, then `resources/list` and `prompts/list` if the capabilities name them. 3. Send no token. The connector sent none and the server answered, so any MCP client can read this list. 4. Calling a tool is a separate step this directory never takes. See [OAuth for MCP: client ID metadata documents and dynamic registration](https://agentmcpdirectory.com/guides/oauth-for-mcp-cimd-dcr/) for how each route works. ## CLI No CLI is on record for Nslookup. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See [shipping a CLI agents can use](https://agentmcpdirectory.com/guides/ship-a-cli-for-agents/). ## Other agent surfaces | Surface | Result | | --- | --- | | OpenAPI file | Not read: the site's robots.txt disallows the path for this crawler. | | WebMCP in the initial HTML | Not checked: the home page was not read by the shared crawl. | | MCP discovery file | Not checked: the domain is not in the shared crawl for this edition. | | A2A agent card | Not checked: the domain is not in the shared crawl for this edition. | | A2A agent card (older path) | Not checked: the domain is not in the shared crawl for this edition. | | agents.json | Not checked: the domain is not in the shared crawl for this edition. | | OAuth authorization server metadata | Not checked: the domain is not in the shared crawl for this edition. | | NLWeb endpoint | Not checked in this edition. | ## Registry listings | Registry | Listed | | --- | --- | | Official MCP Registry | No | | GitHub MCP Registry | Yes | | awesome-remote-mcp-servers | No | | Smithery | Not checked: Smithery's listing pages and search API were unavailable on 4 November 2026. | | Glama | Not checked: Glama's API needs a key and attribution terms. | Edition 4 November 2026 Method [How rows are verified](https://agentmcpdirectory.com/method/) Data [CSV and JSON](https://agentmcpdirectory.com/data/) Markdown [This page as markdown](https://agentmcpdirectory.com/directory/nslookup-io/index.md) ## Sources - [Nslookup website](https://nslookup.io), read 4 November 2026 - [Official MCP Registry API, the registry read for this edition](https://registry.modelcontextprotocol.io/v0/servers), read 4 November 2026 Last reviewed 5 November 2026
