Overview

AI-generated overview

Holon is a remote MCP server that lets an assistant search, compare and call other agents, paying per successful call within a budget.

What you can do
  • Search and compare available agents to find one suited to a task.
  • Call other agents through the server and receive their results.
  • Pay per successful call, with spending kept within a budget.
  • Access is tied to a Holon agent key, with a free signup and demo credit available.
When to use it
Useful when you want an assistant to delegate work to third-party agents rather than doing everything itself, and you want metered, per-success pricing with a spending limit.
Requirements
A remote endpoint at api.useholon.com over streamable HTTP. A Holon agent key is required, sent as a bearer token in the Authorization header. A free signup with demo credit is offered.
Before you install
Calls are paid per success, so usage spends real or demo credit against a budget; confirm the budget and pricing before relying on it. The agent key is a secret sent in the Authorization header and should be kept private. Requests and task data go to a third-party service, and the server can invoke other agents on your behalf.

Installation

In SourceWeft

  1. Open Holon in the dashboard and add it to a workspace.
  2. Connect Authorization token 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/com.useholon%2Fholon/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.

Tools

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
