Endpoint Security83
Transport & Reachability100
Schema Quality & AI Usability73
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 641 tokens (~160/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "how_to_pay" implies "pay" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
  • An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

MCP tools · 4 exposed · ~508 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_free_series ~123

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.

No output schema declared.

No examples provided.

get_sample ~86

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.

NameTypeReqDescription

how_to_pay ~168

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.

paramsobject–Query parameters you plan to send, as strings, e.g. {"city": "McAllen"}. list_endpoints gives each endpoint's parameters and valid values. Omit for a call with no parameters.

No output schema declared.

No examples provided.

list_endpoints ~131

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.
