- Ask a question the tools can answer.
Add to ~/.codex/config.toml:
[mcp_servers.pinloft]
url = "https://pinloft.cybermaxtools.com/mcp?via=use-with-codex"With a paid key:
[mcp_servers.pinloft]
url = "https://pinloft.cybermaxtools.com/mcp?via=use-with-codex"
env_http_headers = { "x-api-key" = "CYBERMAX_API_KEY" }env_http_headers maps the header to an environment variable name, so the key stays in your environment.

Endpoint checked 2026-10-09: https://pinloft.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 2 tools, all marked read-only. No key was used and no tool was called.
| Tool | What it does | Required inputs |
|---|---|---|
geocode_address | Convert up to 5 street addresses to latitude/longitude with a cleaned, matched address and match confidence. US addresses also get state, county, tract, block group and block FIPS codes (US Census geocoder); include_districts adds congressional and state legislative districts, city, school district and metro area. Worldwide addresses use OpenStreetMap. | addresses |
reverse_geocode | Convert up to 5 latitude/longitude points to the nearest street address (OpenStreetMap), and for US points add state/county/tract/block FIPS codes and congressional/state districts from the US Census geocoder. | coordinates |
Test the endpoint from a terminal
This lists the tools without a key and without calling any of them:
curl -s https://pinloft.cybermaxtools.com/mcp \
-H 'content-type: application/json' \
-H 'accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'If it does not work
- Each server is its own [mcp_servers.<name>] table; keep the name to letters, digits, dashes and underscores.
- For a fixed header value instead of an environment variable, Codex also documents http_headers.
- The free tier has a daily limit (see the pricing line above); a paid key raises it.
