My MCPs - Automated MCP Subdomain Delegation Service
You can claim a dedicated subdomain to use as your project's address. Use it as the endpoint for your MCP server or as a simple site to host your documentation
Documentation
0$ Free — the only plan
1 URL to connect your assistant
4 Essential record types
0% DNSSEC-signed zones
Everything included,nothing to configure.
Security and convenience are the defaults, not add-ons.
DNSSEC included
Every zone is automatically signed with NSEC3. Validation-safe out of the box — no key management, no expiry surprises.
Open standard
MCP is an open protocol — bring the client you use today and whatever you prefer tomorrow. No vendor lock on either side.
MCP native
One server URL from your operator, added to your favourite MCP client — Codex, Claude Code, Cursor, OpenCode or anything that speaks MCP.
Plain-language control
"Claim the subdomain iris for me." Your assistant checks availability, verifies you, and does the rest — no forms, no dashboards.
Essential DNS records
A, AAAA, CNAME and TXT — set, update or remove them by simply asking. Need more? Delegate the whole subdomain to a third-party nameserver of your choice.
Bring your own nameserver
Delegate your whole subdomain to third-party nameservers whenever you outgrow the operator's zone — one sentence, handled.
Secrets stay yours
You get a one-time login token and an optional recovery key, shown exactly once. The server never echoes them back.
Questions, answered.
Is it really free?
Yes — claiming and using your subdomain costs nothing. Free is the whole point, not a trial.
What is an MCP server?
MCP (Model Context Protocol) is the standard way AI clients connect to external tools. mcp-semeion is a remote MCP server: once your client knows its URL, your assistant can claim and manage subdomains for you — you never call it directly.
Which AI clients work with mcp-semeion?
Anything that speaks MCP: Codex, Claude Code, Cursor, OpenCode and most others. Add it as a remote server with the URL your operator gave you — the connect dialog has copy-paste snippets.
What is the scope of mcps.my services?
mcps.my is a specialized subdomain registry designed for the Model Context Protocol ecosystem and beyond. We provide developers with standardized subdomains to act as unique identifiers for their distributed services.
Our subdomains are ideal for:
- MCP Server Endpoints: Providing a consistent URL for your protocol implementations.
- Project Documentation: Serving as a lightweight web presence for your open-source or private MCP tools.
- Custom Tooling: Any specialized service that benefits from being part of the mcps.my ecosystem. The name I want is already taken.
Then it's gone — subdomains are first come, first served. Pick another label; short and memorable beats clever and long.
Can I delegate my subdomain to other nameservers?
Yes. Set NS records for your subdomain to delegate it elsewhere. If the other operator doesn't support DNSSEC, simply don't publish a DS record — the delegation is then provably insecure and keeps resolving everywhere.
Can I change or release my subdomain later?
Your records are yours — set, change or delegate them at any time. The name itself isn't transferable, but you can release it when you no longer need it. No lock-in.
What if I lose my login token?
Set up a recovery key while you still have access — it reconnects you to the same subdomain. Both secrets are shown exactly once; the server never echoes them back.
What do you collect?
Nothing, basically. This page is static — no cookies, no trackers, no analytics — and DNS gets answered without keeping a log of who asked. The registry holds your records and your login secrets, and that's the whole file.
Is this site AI-generated?
Yes — and the EU agrees that's worth saying plainly. Copy, canvas and code, all of it came out of AI sessions, directed by an AI agent from first prompt to final pixel. Welcome to the future. Want one like it? Ask your code agent — that's how this one was made.
Do I need to understand DNSSEC?
No. Keys are generated, rotated and published automatically, and every answer your visitors receive is cryptographically signed. It just works.
Is this service going to change my life?
It's a subdomain. It's going to give your MCP server a professional-looking URL. It won't solve your relationship problems or fix your broken code. Next question.
