endpoints
list_endpoints
List every paid Frontera Signal endpoint before you spend anything. Covers Rio Grande Valley, Texas market data: construction (permits, building-input prices, housing supply, labor, commercial projects filed with the state, company track records, filed cost per square foot, material shelf prices, the weekly briefing), bridge wait times, border crossings, peso, diesel, city sales tax, new businesses, bar and restaurant alcohol sales and home health agencies. Each entry has the price per call in USDC, what the call returns, an example question, its parameters with valid values and a free sample URL. Free.
free
get_free_series
Get the latest 4 weeks of a weekly Rio Grande Valley series for free: permits-weekly (building permits by city), cost-basket-weekly (building-input prices), absorption (housing supply), labor-ranges (labor and financing conditions) or calls (graded forecasts). Each row carries its week, as_of date and status. The full history is a paid endpoint; how_to_pay with series-<name> gives its URL and price.
how
how_to_pay
Get the exact URL to call for a paid answer, with its price, network and asset. Pass the endpoint key and the query parameters you plan to send; they go through the same free check the API runs before payment, so a query that would be refused or come back empty shows up here. This tool never calls the paid endpoint and never pays. Payment is x402: no account or API key, USDC on Base.
sample
get_sample
Get a real answer from one paid endpoint for free, exactly as a paid call returns it, so you can check the fields, dates and coverage before you pay. Pass the endpoint key from list_endpoints, such as snapshot, projects or series-permits-weekly.

Frontera Signal — questions

Answers built from our own checks of this server.

What can Frontera Signal do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_free_series, get_sample, how_to_pay, list_endpoints. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Frontera Signal working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 463 ms. The bar chart above shows every period we have measured.
How do I connect Frontera Signal?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Frontera Signal need an API key?
No. Frontera Signal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Frontera Signal?
It answers our handshake in 463 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
