OSIR Agent Platform

AI integration servers for the OSIR domain registrar. Connect Claude, ChatGPT, or any AI assistant to real domain, DNS, VPS, billing, and account operations — either as individual tools (MCP) or as task-solving specialist agents (A2A).

Two servers, one shared backend client library:

ServerPortProtocolWhat it gives an AI
MCP Server8081Model Context Protocol (SSE + Streamable HTTP)103 fine-grained tools (checkDomainAvailability, registerDomain, createDnsRecord, createMailbox, osirSitePublish, …) + 11 guided prompts
A2A Server8082Google Agent-to-Agent (JSON-RPC 2.0)9 specialist agents with 89 skills and an orchestrator for multi-step workflows

Use MCP when one assistant should call individual operations. Use A2A when you want to hand a whole task ("set up example.com with DNS and check my balance") to agents that coordinate the work.


What is MCP?

MCP (Model Context Protocol) is an open standard that connects AI assistants to external tools and data. An MCP server publishes a set of callable tools; any MCP client — Claude Desktop, Cursor, Copilot, or a custom agent — can discover and invoke them. OSIR implements an MCP server purpose-built for domain and infrastructure management, which is what makes it an AI-native registrar rather than a traditional one with a chat box bolted on.

Connect OSIR to Claude

In Claude, open Settings → Connectors → Add custom connector, then pick one of two setups:

Option A: No sign-in (recommended)Option B: OAuth
Server URLhttps://be.osir.com/mcp/httphttps://be.osir.com/mcp/oauth
AuthenticationNo sign-inSign in now
OAuth client—Use your own OAuth client, Client ID mcp-client, secret blank
LoginIn the chat, one conversation at a time (below)Browser login when you add the connector; the connector stays signed in

For Option B, don't pick "Use Claude's published identity" or "Register automatically". OSIR doesn't support either one.

Option A: signing in happens inside the conversation. The first time your assistant needs an authenticated tool, it starts a device login: you get a link to auth.osir.com and a short code, you approve in your browser, and the assistant continues with a session scoped to that conversation. Sessions are deliberately short-lived (they expire after ~30 minutes of inactivity, 8 hours maximum) and end instantly when you say "log me out" — so a connected chat never holds standing access to your domains, servers, and billing.

The same URL works in any MCP client that supports a remote (streamable HTTP) server and can drive the in-chat device login.

Self-hosting note: /mcp/oauth always requires OAuth: it returns 401 with an RFC 9728

challenge. The URL-only /mcp/http needs MCP_OAUTH_CHALLENGE_ENABLED=false. If you leave

that at its default (true), every MCP path requires OAuth. Session lifetimes

are tunable via MCP_SESSION_IDLE_MINUTES and MCP_SESSION_MAX_HOURS.

What your assistant can do
CapabilityExample request
Search availability"Is coolstartup.io available, and what does it cost?"
Register a domain"Register it for two years with WHOIS privacy."
Manage DNS"Point it at 192.0.2.10 and add my email records."
Renew and transfer"Renew everything expiring in the next 30 days."
Provision a VPS"Spin up a 2 vCPU server in Frankfurt running Ubuntu."
Host email"Enable email on example.com and create info@ with a 10 GB mailbox."

Running the servers yourself

Want to host your own instance or develop against the code? Requires Java 21; Gradle is bundled via the wrapper.

# Run the MCP server (port 8081)

./gradlew :mcp-server:quarkusDev

Run the A2A server (port 8082)

./gradlew :a2a-server:quarkusDev

Copy .env.example to .env and adjust if you're pointing at your own backend/KeyCloak. Everything defaults to the public OSIR endpoints, so the servers run out of the box.

Connect an MCP client (Claude Desktop / Claude Code)

Add to your client's MCP config (e.g. claude_desktop_config.json):

{

"mcpServers": { "osir": { "url": "http://localhost:8081/mcp/sse" } } }

Restart the client and the OSIR tools appear. Then just ask:

"Is pizzashqip.al available? If not, suggest alternatives."

"List all my domains and show which expire in the next 30 days."

"Add an A record pointing example.al to 203.0.113.10 and a CNAME for www."

Most operations need authentication — ask the assistant to *"log me in to OSIR using the device flow"* and it walks you through browser-based OAuth (KeyCloak, RFC 8628).

Call the A2A server
# Discover the agents

curl http://localhost:8082/.well-known/agents | jq '.[].name'

Send a task (the platform routes it to the right specialist)

curl -X POST http://localhost:8082/a2a \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_TOKEN" \ -d '{ "jsonrpc": "2.0", "id": "1", "method": "tasks/send", "params": { "message": { "role": "user", "parts": [{"type": "text", "text": "Check if example.com is available"}] } } }'

Tasks stream over POST /a2a/stream (SSE), support multi-turn input-required flows, and the orchestrator decomposes complex requests across agents (max 15 steps).


What you can do

Domains — availability, registration, renewal, transfer, lock/unlock, auto-renew, WHOIS privacy, nameservers, AI-powered name suggestions. DNS — list/create/update/delete records. VPS — browse packages and locations, order, manage, panel login. Billing — balance, invoices, payments, fee previews, domain pricing. Contacts, Transfers, Hosts, Audit logs, Account profile & summary.

Full tool/skill catalog, example conversations, and end-to-end walkthroughs are in [GUIDE.md](docs/GUIDE.md).
