"Transmission" matching MCP servers:

Lets AI agents issue and query Colombia DIAN electronic invoices (factura electrónica) via the Matias API, handling IVA math locally and forwarding requests to Matias for signing and DIAN transmission.

Enables AI assistants to interact with TradingView Desktop via Chrome DevTools Protocol for chart analysis, Pine Script development, and workflow automation, all locally without external data transmission.

Enables MCP clients to fill any German ELSTER tax form by Kennzahl, start or continue returns, run the portal's own checks, and review every row before transmission. It never submits; the finished form is handed off in a visible browser for the user to send.

Enables local inspection of synthetic ACH files by parsing fixed-width records, validating structure and control totals, explaining findings, masking sensitive fields, repairing derived controls, and generating deterministic test files. All work happens on-device with no bank or network transmission.
