@assemblyline-agents/treg

Official Assembly Line connection plugin for Treg's hosted tool-catalog MCP server. The connection exposes a small reviewed discovery and calling surface; Treg's provider catalog remains remote data rather than thousands of static tool schemas in the agent prompt.

Install and configure

assembly-line add treg agent

The command selects capabilities: [treg] and updates plugins.lock; it does not create a root connection file.

Create an organization-scoped or agent token in Treg, then set it on the Assembly Line runtime:

TREG_TOKEN=your_treg_token

The connection uses https://treg.to/mcp/ by default. Set TREG_MCP_URL to the MCP endpoint of a self-hosted registry.

Reviewed tools

The plugin allows these Treg MCP tools:

• catalog_search, catalog_get, balance, and my_tools are reads.
• catalog_request is a write because it files a request in Treg.
• call is a write because it can spend prepaid balance or relay a mutating request to an upstream service.

New upstream tools remain hidden until the plugin reviews and classifies them.

Require approval for both reviewed writes when the agent should not spend or invoke upstream actions autonomously:

capabilities:
  treg:
    connections:
      treg:
        approval:
          catalog_request: always
          call: always
