Magic MCP vs Ssid MCP
A side-by-side look at the Magic MCP and Ssid MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Magic MCP for architecture & design work as a local process; choose Ssid MCP for security as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Magic MCP when
- You need dedicated capabilities in the Architecture & Design domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
TWENTY_FIRST_API_KEY, API_KEY_21ST.
Choose Ssid MCP when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
SSID_API_KEY. - You want tools like
get_router_defaults, check_router_compliance, lookup_mac.

Ssid MCP tools 4
get_router_defaultsDefault gateway IP, admin username and password (or the fact that there is none), credential type and factory-reset steps for a router or gateway model, each cited to the manufacturer's own documentation with the source URL. Pass the ssid.ai slug, or brand plus model. Use after lookup_mac identifies the vendor, or whenever a user asks for a router's default login, factory password, gateway address or reset procedure. Covers the 409-model ssid.ai directory; no listing or wildcard search.check_router_complianceWhether a router model still ships a universal default password, the pattern prohibited for consumer connectable products under the UK PSTI Act and targeted by the EU Cyber Resilience Act, based on the manufacturer-cited credential type, with the ssid.ai Router Compliance Index totals for context. Pass the ssid.ai slug (get it from get_router_defaults). Documentation reading, not legal advice.lookup_macIdentify the organisation behind a MAC address and detect randomized/private (locally-administered) addresses used by modern phones. Resolves the IEEE registries longest-prefix-first, so an address inside a block the IEEE subdivided returns the company that actually holds it (MA-M, MA-S or IAB) rather than the MA-L registrar. Returns vendor, blockType (MA-L | MA-M | MA-S | IAB), block start/end for a sub-block, OUI, kind, randomized flag, confidence and the source registry file. A randomized address keeps vendor: null and adds cidRegistrant when its prefix is a registered Company ID (DA:A1:19 is Google's). For the router's factory login, call get_router_defaults next.submit_correctionPropose a fix to a router model's default gateway IP, username, password, credential type, or reset steps on ssid.ai. Requires an official manufacturer source URL (never an aggregator/forum). Queued for verification — never applied automatically. Use the router's slug from ssid.ai/routers/<slug>. Requires an ssid Pro key ($15/mo, ssid.ai/pricing) sent as SSID_API_KEY or a Bearer token; the three read tools stay free.

Frequently asked questions
Magic MCP is categorized under Architecture & Design and uses a local stdio subprocess. Ssid MCP belongs to Security and uses a local stdio subprocess. Pick Magic MCP for architecture & design work and Ssid MCP for security.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Magic MCP is listed as a paid service. Auth: api key required. Ssid MCP has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add 21st-dev-magic-mcp and ssid-mcp-2 as separate keys in the same mcpServers object, and your assistant will call tools from either one.
