Overview

AI-generated overview

Sigil is a remote MCP endpoint for programmatic-advertising supply verification, covering ads.txt, schain and ATAP receipts through a cross_lens_verify tool.

What you can do
Verify advertising supply data such as ads.txt records and supply-chain (schain) objects through the cross_lens_verify tool, and check ATAP receipts as part of that verification. The manifest lists no individual tools, so the exact operations are not documented here.
When to use it
Relevant when an assistant needs to check programmatic-advertising supply paths, ads.txt or schain data, or ATAP receipts during ad-ops or verification work.
Requirements
A remote MCP endpoint reached over streamable HTTP at the provider's hosted address; no packages, environment variables or headers are declared. The manifest declares no authentication, so whether an account or key is needed is not stated.
Before you install
The manifest declares no authentication and no credentials, so it is unclear what data is sent to the provider or who can call it. Verification results should be treated as advisory until the provider's methodology is confirmed.

Installation

In SourceWeft

  1. Open Sigil 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.tunnelmind%2Fsigil/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
