Is my Real Estate Information Library API (MLIT Japan) credential exposed to the agent?

No. Relvo stores the credential and adds it server-side. The agent holds only its Relvo token, never the account's secret.

Are write calls retried?

No. Relvo never retries a write automatically; a call that may already have reached Real Estate Information Library API (MLIT Japan) is returned for review instead.

Create an account, connect Real Estate Information Library API (MLIT Japan) under Connections, and add https://app.relvo.si/mcp to your agent.

Set up Relvo for Real Estate Information Library API (MLIT Japan)

Pick the client you use, then pick a route: Automatic is that client's own link, command or prompt, and Manual is the same install done by hand. Both end at the same OAuth sign-in, with every tool on the Real Estate Information Library API (MLIT Japan) shelf behind one connector.

One link fills in the dialog.

On a desktop browser this opens Claude's Add custom connector form with Relvo's name and MCP URL already in place. Click Add and sign in — there is nothing to type.

Add the Relvo connector

Open the dialog
Click the button above in the browser where you are signed in to Claude. Customize → Connectors opens with the custom-connector form ready.
Add and authorise
Click Add, then choose Sign in now under Authentication. Relvo signs you in over OAuth, so no token or API key is pasted into Claude.

The agent picks the matching operations, runs them on your connection, then relays the provider's response verbatim.

Automatic way

One command, then one sign-in.

The CLI registers Relvo with HTTP transport and writes it into your Claude Code config; authentication happens in the browser.

Run the command

BASH

claude mcp add --transport http relvo https://app.relvo.si/mcp

Authenticate once
Open a session and run /mcp. Choose Relvo → Authenticate; Claude Code opens Relvo's OAuth page and stores the token for the project.

Using Relvo, find the right Real Estate Information Library API (MLIT Japan) tool to get emergency evacuation shelters and run it on my Real Estate Information Library API (MLIT Japan) connection. Return Real Estate Information Library API (MLIT Japan)'s response as it comes back.

The client picks the matching operations and runs them on your connected account.

The command uses local scope by default. Add --scope user to make Relvo available in every project, or --scope project to share it through the repository.

Manual way

Write it into .mcp.json.

Project scope lives in a file, so the whole team gets Relvo without running a command.

Add the server

JSON · .mcp.json

{
  "mcpServers": {
    "relvo": {
      "type": "http",
      "url": "https://app.relvo.si/mcp"
    }
  }
}

Create .mcp.json in the project root and add relvo as an HTTP server.

Reload and sign in
Start a Claude Code session, run /mcp, choose Relvo → Authenticate, then reload. The tools are available in that project.

Using Relvo, find the right Real Estate Information Library API (MLIT Japan) tool to get emergency evacuation shelters and run it on my Real Estate Information Library API (MLIT Japan) connection. Return Real Estate Information Library API (MLIT Japan)'s response as it comes back.

The agent picks the matching operations, runs them on your connection, then relays the provider's response verbatim.

The same entry works for every project when it is added at user scope instead of project scope. All 36 Real Estate Information Library API (MLIT Japan) operations run on your connected Real Estate Information Library API (MLIT Japan) account. Relvo charges no usage fee; Real Estate Information Library API (MLIT Japan) may bill that account on its own plan.

Automatic way

Hand the setup to Hermes.

Hermes can edit its own config, so one instruction is enough: it writes Relvo into mcp_servers, reloads, and reports the tools it can now call.

Copy the setup prompt

PROMPT

Add Relvo as a remote MCP server named "relvo": url https://app.relvo.si/mcp, auth oauth. Follow https://app.relvo.si/SKILL.md, reload MCP, then list the Relvo tools.

Paste it into a Hermes session
Hermes adds the remote server to ~/.hermes/config.yaml and reloads its MCP connections.
Approve the sign-in
Open the OAuth link Hermes prints and approve Relvo once. The token is cached, so later sessions do not ask again.

Manual way

Add it to ~/.hermes/config.yaml.

Two settings and one reload — the same entry Hermes would write itself.

Open the config
Edit ~/.hermes/config.yaml, the file Hermes reads at start-up.

Add the server

YAML

mcp_servers:
  Relvo:
    url: https://app.relvo.si/mcp

Add Relvo to Cursor

Open the install prompt
Click the button on the machine where Cursor is installed. Cursor receives a server named relvo pointing at https://app.relvo.si/mcp.

The client picks the matching operations and runs them on your connected account.

The install link opens Cursor directly, so it does nothing in a browser that has never installed the editor.

Manual way

Edit ~/.cursor/mcp.json.

Use the global or the project file when you want the entry under your own control.

Open the MCP config
Edit ~/.cursor/mcp.json for every project, or .cursor/mcp.json inside the repository for one.
