_ is it live, free and safe measured by this hub
Is emission-factors live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is emission-factors free to use?
Yes — the hub reached it with no key and no payment.
What tools does emission-factors have?
11 tools: calculate_emissions, hourly_intensity, plant_emissions, utility_tariff, electricity_rate, compare_sites, cleanest_hours, calculate_fuel_emissions, ….
Is emission-factors safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 11 tools

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • calculate_emissions unknown never probed

    Calculate Scope 2 CO2e for a facility from its ZIP and kWh, using both GHG Protocol methods: location-based (eGRID subregion rate) and market-based (Green-e residual mix applied to kWh not covered by RECs, PPAs or green tariffs). Returns kg CO2e for each method with the factors used.

  • hourly_intensity unknown never probed

    Get hourly grid carbon intensity (kg CO2e per kWh) for any US ZIP code, derived from EIA-930 hourly fuel-mix data. Data lags approximately 24 hours (not real-time). Returns time series with per-hour fuel mix, total generation, and carbon intensity. Useful for backtesting demand response, computing post-hoc time-weighted Scope 2 emissions, or analyzing grid carbon patterns. For live or forecast intensity, WattTime or Electricity Maps are better options.

  • plant_emissions unknown never probed

    Get hourly unit-level emissions from EPA Clean Air Markets Division (CAMD) for a specific US power plant or state. Covers ~1,300 fossil units >25 MW reporting to the Acid Rain Program and CSAPR. Per facility returns total CO2 (short tons), gross generation (MWh), heat input (mmBtu), NOx and SO2 (lb), primary fuel type, operating hours, and derived emissions rate (kg CO2/MWh). Data has ~21 day lag to ensure CAMD has published. Use for plant-specific carbon accounting, state-level fossil emissions aggregation, and "dirtiest plants in [state]" queries. Paywall-free alternative to S&P Global Market Intelligence ($30k+/yr).

  • utility_tariff unknown never probed

    Get the actual utility-specific electricity rate (not state average) for a US ZIP code or named utility. Returns the current default tariff with effective rate ($/kWh), fixed monthly charge, tier count, TOU indicator, and effective date. Data source: OpenEI URDB (NREL-hosted). Covers ~85% of US utilities. Upgrade from /api/rate (state average). For example, California state avg is $0.30/kWh but actual tariffs range from $0.21 (CleanPowerSF) to $0.52 (PG&E peak TOU). Does not cover Texas retail electric providers outside the old TDU territory (deregulated market).

  • electricity_rate unknown never probed

    Get the latest monthly average retail electricity rate ($/kWh and cents/kWh) for any US ZIP code, broken out by sector (residential, commercial, industrial, etc.). Data is state-level from EIA Form 861 - a ballpark, not utility- or ZIP-specific tariffs. Pairs with emission factors to estimate carbon cost in $/tCO2e.

  • compare_sites unknown never probed

    Compare and rank 2-25 candidate US sites (ZIP codes) for a facility, data center or EV/flexible load on grid carbon and electricity cost in one call. Per site: eGRID CO2e kg/kWh (location-based), Green-e residual mix (market-based), carbon-free %, state retail $/kWh for the sector, and the cleanest daily window from the hourly grid profile. With annual_kwh, also annual tCO2e and annual cost. Returns ranks by carbon, cost and combined.

  • cleanest_hours unknown never probed

    Find the cleanest (lowest grid carbon) contiguous window of N hours in the day to run a flexible load (batch jobs, EV charging, pumping, HVAC pre-cooling) at a US ZIP code or balancing authority. Based on the hour-of-day pattern of the last ~7 days of EIA-930 data, in local time. Returns the cleanest and dirtiest windows, % saved vs the daily average, and all hours ranked. A scheduling guide from recent history, not a forecast.

  • calculate_fuel_emissions unknown never probed

    Calculate Scope 1 stationary-combustion emissions (CO2, CH4, N2O and CO2e) for fuels burned on site, using the EPA GHG Emission Factors Hub (2025). Pass one or more items with fuel, quantity and unit, e.g. natural gas in therms/ccf/mcf/scf, propane/diesel/heating oil in gallons, coal in short tons. Biomass CO2 is reported separately (biogenic). Returns per-item and total CO2e. Pair with calculate_emissions for a facility's electricity (Scope 2).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id ab30b8cee8c338b6.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ab30b8cee8c338b6/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
