Overview

AI-generated overview

Remote pay-per-call MCP server for company, compliance and public-record lookups: SEC filings, sanctions screening, tenders, KYB, web reading and domain…

What you can do
  • Look up company and filing data: SEC 13F holdings, 8-K filings, GLEIF/SEC KYB verification and Japanese qualified-invoice registration status
  • Screen names and wallets: OFAC SDN and UK sanctions lists for people and entities, plus EVM address risk against OFAC and a phishing list
  • Find procurement notices: bundled EU, UK, France and Australia tenders, plus separate UK, French and Australian contract feeds
  • Read and crawl the web: one page or up to 20 pages under a start URL as Markdown
  • Profile a domain: DNS records, SPF/DMARC, mail and hosting providers, TLS issuer and homepage tech stack
  • List open jobs from named Lever boards
When to use it
Useful when an assistant needs current public-record facts about companies, filings, sanctions exposure, public tenders or a domain, without building separate integrations. Each tool is billed per call, so it suits occasional targeted lookups rather than bulk data collection.
Requirements
A remote streamable HTTP endpoint; no local package, account, API key or environment variable is declared. Calls are paid per use through x402, so a wallet or payment-capable client is implied by the pricing. Network access to the endpoint and to the underlying public sources is required.
Before you install
Most tools charge per call (for example 0.02 to 0.11 USD), so repeated or paged calls spend money; a free sample is offered per tool. Web read and crawl tools put the caller responsible for the target site's terms. Results are drawn from third-party public lists and feeds with stated snapshot dates, so verify before relying on them for compliance decisions.

Installation

In SourceWeft

  1. Open Johto Data 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/com.johtodata%2Fjohto-data/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.
