Overview

AI-generated overview

LongSpan connects an assistant to a household's long-range financial plan so it can read the plan, run what-if scenarios and keep it updated.

What you can do
  • Read the household's long-range financial plan.
  • Explore what-if scenarios against the plan.
  • Update and maintain the plan over time.
  • No individual tools are documented, so the exact actions available are not specified.
When to use it
Useful when you want an assistant to reason about a household's long-term finances, test alternative assumptions, or keep an existing plan current without switching to a separate app.
Requirements
A remote MCP endpoint at api.longspan.app over streamable HTTP. Sign-in with OAuth is required; no environment variables or headers are declared.
Before you install
The server holds sensitive household financial data and requires an OAuth sign-in, so grant access only to an account you trust. The description mentions changing the plan, so expect writes to your data; no tool list is published to confirm what can be modified.

Installation

In SourceWeft

  1. Open LongSpan in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/app.longspan%2Flongspan/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. The client completes OAuth sign-in on first connect.

{
  "mcpServers": {
    "longspan": {
      "type": "http",
      "url": "https://api.longspan.app/mcp"
    }
  }
}

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

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.
