Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to www.edgethirteen.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Checks ticker-tagged numeric claims in financial writing against SEC EDGAR XBRL data from the company's latest 10-K.

What you can do: Check financial numbers in a piece of writing: scan $CASHTAG-style ticker mentions such as $AAPL and compare the associated figures against SEC EDGAR XBRL company facts from the most recent 10-K.
Compare specific metrics: EPS, book value per share, revenue, market cap, total assets and total liabilities.
Flag numeric claims that do not match the filed figures.
When to use it: Useful when drafting or reviewing financial writing that cites per-share, revenue, asset or liability figures and you want a quick cross-check against what the company actually filed with the SEC.
Requirements: A remote streamable HTTP endpoint; no package, environment variables or headers are declared. The server relies on SEC EDGAR XBRL company-facts data, so network access to that source is implied.

Before you install

Only the latest 10-K is used, so figures from other periods or filings may be flagged even if correct elsewhere. Treat flags as a prompt to verify rather than as proof of error, and check the company's own filings before publishing.

Installation

In SourceWeft

Open Numbercheck in the dashboard and add it to a workspace.
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.edgethirteen.www%2Fnumbercheck/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
