ARVX

Email for long-term client relationships: ARVX reads each person first and remembers every pair.

Overview

AI-generated overview

ARVX runs "Readings" on two people from the emails between them, returning relationship signals, predictions and a saved record.

What you can do
  • Run a Reading on a pair of people from at least three emails each, oldest first
  • Return area-by-area colors, up to three predictions, what changed since the last Reading, and outside context on the other person
  • Pass back the sealed record from the previous Reading on the same pair to continue the series
  • Summarize everything held in a saved record in plain words when someone asks
  • Explain how to get access, the price, and how to add the key
When to use it
For people or products working on long-term client or partner relationships who want an outside read on how an email exchange is going and what may happen next, and who are willing to pay per Reading after the first three.
Requirements
A remote MCP endpoint; an ARVX key created by the person themselves at the ARVX account site, sent in the x-arvx-key header (or as a bearer token). Readings cost money after the first three free ones, prepaid, and Stripe identity verification is required before the first payment.
Before you install
The key is a secret and should go in client settings, not in chat. Readings cost 43 cents each after three free ones, so usage spends money. You send real email content about two named people to a third-party service; the README says addresses are not stored or sent to a model, but the emails themselves are submitted. Record summaries are limited to 10 a month per account.

Installation

In SourceWeft

  1. Open ARVX in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.arvx%2Farvx/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

  "mcpServers": {
    "arvx": {
      "type": "http",
      "url": "https://mcp.arvx.ai/mcp"
    }
  }
}

README

ARVX connector

Email for long-term client relationships: ARVX reads each person first and remembers every pair.

Building a CRM or an email tool? ARVX is the bridge between your product and the email client. It reads each person first, knows their normal, and remembers every pair.

This connector lets any MCP-compatible AI assistant or coding agent run ARVX Readings. It keeps nothing: your key travels with each request to ARVX and is never stored.

What a Reading returns

Every Reading is on two people: the person you work for and a person they work with, read from the emails between them.

  • Colors, area by area (clarity, cadence, responsiveness, bench strength, meaningful moments): how this exchange fits this person. Green on target, yellow drifting, red off.
  • Up to three predictions: what ARVX expects next, each with what to do if it happens.
  • What moved since the last Reading on the same pair.
  • Up to two lines on what is acting on the other person this week: company news, severe weather, a U.S. holiday.
  • A sealed record only ARVX can open. Save it and send it back with the next Reading on the same pair.

ARVX never returns a score, a trait rating or a personality label on a named person. Email addresses are never stored and never sent to an AI model.

Tools

  • arvx_get_access: the signup link to give the person, the price, and how to add the key. Needs no key.
  • arvx_run_reading: runs a Reading on two people. The first 3 are free, then 43¢ each, prepaid.
  • arvx_record_summary: when someone asks what is held about them, every item in a saved record in plain words.

Get a key

A person must sign up at https://api.arvx.ai/account, accept the terms and create the key. An agent cannot. Before the first payment, Stripe checks a photo ID and a selfie, once.

Connect

Add a remote MCP server at:

https://mcp.arvx.ai/mcp

with your key in the x-arvx-key header (or Authorization: Bearer <key>). Put the key in your client's settings, never in a chat. For example:

json
{  "mcpServers": {    "arvx": {      "type": "http",      "url": "https://mcp.arvx.ai/mcp",      "headers": { "x-arvx-key": "YOUR_ARVX_KEY" }    }  }}

arvx_get_access

How to get access to ARVX: the signup link to give the person, what they must do themselves, the price, and how to add their key to this connector. Call this when there is no key, or when the person asks how to start. Costs nothing.

Takes no parameters.

arvx_run_reading

Run a Reading on two people from the emails between them. Send at least 3 emails written by the user and 3 by the other person, oldest first. From the second Reading on a pair, send the record from the last Reading exactly as it was returned. Costs one Reading (the first 3 are free). Save the record from the answer with this pair.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
