Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read devices, users, keys, ACLs and DNS for a tailnet; manage devices, routes and auth keys.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Works in Claude on the web, desktop and mobile:
https://tailscale.usefulapi.io/mcpRun this in your terminal
claude mcp add --transport http tailscale https://tailscale.usefulapi.io/mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"tailscale": {
"url": "https://tailscale.usefulapi.io/mcp"
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Paste into .vscode/mcp.json in your project

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
tailscale_list_devicesList all devices in the tailnet (name, addresses, OS, last seen, tags, etc.). Tailscale REST: GET /tailnet/{tailnet}/devices.
tailscale_get_deviceGet a single device by id. Tailscale REST: GET /device/{deviceId}.
tailscale_list_device_routesList the subnet routes a device advertises and which are enabled. Tailscale REST: GET /device/{deviceId}/routes.
tailscale_list_keysList auth keys and API access tokens for the tailnet. Tailscale REST: GET /tailnet/{tailnet}/keys.
tailscale_get_keyGet details of a single auth key / API access token by id (capabilities, expiry, usage). Tailscale REST: GET /tailnet/{tailnet}/keys/{keyId}.
tailscale_get_policy_fileGet the tailnet's ACL / policy file (returned as JSON via the Accept header, not HuJSON). Tailscale REST: GET /tailnet/{tailnet}/acl.
tailscale_list_dns_nameserversList the global DNS nameservers configured for the tailnet. Tailscale REST: GET /tailnet/{tailnet}/dns/nameservers.
tailscale_get_dns_preferencesGet the tailnet's DNS preferences (e.g. whether MagicDNS is enabled). Tailscale REST: GET /tailnet/{tailnet}/dns/preferences.
tailscale_list_dns_searchpathsList the DNS search paths (search domains) configured for the tailnet. Tailscale REST: GET /tailnet/{tailnet}/dns/searchpaths.
tailscale_get_split_dnsGet the tailnet's split-DNS configuration — a map of domain → nameservers. Tailscale REST: GET /tailnet/{tailnet}/dns/split-dns.
tailscale_list_usersList users of the tailnet, optionally filtered by type, role or status. Tailscale REST: GET /tailnet/{tailnet}/users.
tailscale_get_userGet a single user by id. Tailscale REST: GET /users/{userId}.
tailscale_list_webhooksList the webhook endpoints configured for the tailnet. Tailscale REST: GET /tailnet/{tailnet}/webhooks.
tailscale_get_tailnet_settingsGet the tailnet's settings (device approval, key expiry, posture, etc.). Tailscale REST: GET /tailnet/{tailnet}/settings.
tailscale_authorize_deviceAuthorize or de-authorize a device (only relevant when device approval is enabled for the tailnet). Tailscale REST: POST /device/{deviceId}/authorized.
tailscale_set_device_nameSet (rename) a device's name. Tailscale REST: POST /device/{deviceId}/name.
tailscale_set_device_tagsSet a device's ACL tags. REPLACES the device's existing tags. Tailscale REST: POST /device/{deviceId}/tags.
tailscale_expire_device_keyExpire a device's node key, forcing it to re-authenticate — a security response to a compromised or lost device. Tailscale REST: POST /device/{deviceId}/expire.
tailscale_set_device_routesSet the subnet routes ENABLED for a device (from the routes it advertises). REPLACES the enabled set. Tailscale REST: POST /device/{deviceId}/routes.
tailscale_create_auth_keyCreate a new auth key for the tailnet (used to register new devices). Tailscale REST: POST /tailnet/{tailnet}/keys.
tailscale_delete_keyDelete (revoke) an auth key or API access token by id — a security response. Tailscale REST: DELETE /tailnet/{tailnet}/keys/{keyId}.
tailscale_delete_deviceDelete a device, removing it from the tailnet. Tailscale REST: DELETE /device/{deviceId}.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.35.3) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Use your Tailscale account from Claude, Cursor, or any MCP client — read devices, users, keys, ACLs and DNS for a tailnet, and manage devices, routes and auth keys. Hosted, no local install: connect with your own credentials.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Tailscale credentials.

On first connect you'll provide your Tailscale API access token (admin console → Settings → Keys), optionally scoped to a tailnet. It is validated, stored per-user, and scoped to you — no keys in config files.
