Available tools 26

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

aggregate

aggregate_charging_utilization

Station-level utilization aggregated over a GeoJSON area and a date window of at most 92 days, optionally filtered to a capacity band (default 150 kW = HPC; pass 100 for fast charging). The reply is one row per station, so it reads an area without pulling any station's daily rows.

aggregate_evse_utilization

EVSE-level utilization aggregated over a GeoJSON area and a date window of at most 92 days, optionally filtered to a capacity band. The per-connector counterpart of aggregate_charging_utilization.

corridor

corridor_benchmark

How does this site's demand per EVSE-day compare with the corridor drawn around it? Reads the corridor_benchmark claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

corridor_comparison

How does this site compare with the named stations around it — distance, EVSE count, max kW, and sessions per EVSE-day each? Reads the corridor_comparison claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

estate

estate_coverage

Which estate sites reported on every day of the window, which are partial or young, and how full is the window's final day? Reads the estate_coverage claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

estate_monthly_series

Did demand per EVSE across the estate move month over month, and did each focus site move with it? Reads the estate_monthly_series claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

site

site_profile

What is this site — how many EVSEs, and how close is the nearest station? Reads the site_profile claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

site_ranking

How do the estate's sites rank on sessions per EVSE-day over one window, and how far is the leader above the estate median? Reads the site_ranking claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

total

total_charging_minutes

How many minutes of charging did this site actually deliver over the window? Reads the total_charging_minutes claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

total_sessions

How much charging demand did this site see over the window? Reads the total_sessions claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

area

area_benchmark

How hard is each EVSE at this site working compared with the area around it? Reads the area_benchmark claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

avg

avg_session_minutes

How long does a session at this site actually last? Reads the avg_session_minutes claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

busy

busy_evse_hours

How many EVSE-hours at this station carried charging on the drilled day, and how many of its EVSEs were charging at once in the busiest hour? Reads the busy_evse_hours claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

charging

search_charging_stations

Find charging stations in one country by structured filter — id, title, address, operator. The reply is the API payload inline: station ids, titles, addresses and operators, which is what the claim tools take as site_id and station_id.

daily

daily_spike

Which days ran far above this site's normal, and by how much? Reads the daily_spike claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

day

day_vs_similar

Was one particular day unusual for the day of week it fell on? Reads the day_vs_similar claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print.

hourly

hourly_spike

When in the day does demand at this site peak? Reads the hourly_spike claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

monthly

monthly_sessions_per_stall_day

Is demand per EVSE rising or falling month over month? Reads the monthly_sessions_per_stall_day claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

nearby

nearby_charging_stations

List the charging stations within a radius of a point, nearest first. The radius is in kilometres and at most 10; the reply is the API payload inline. This is how a site's competitors are found before any claim is read.

peak

peak_hour_co_saturation

When the site reaches its busiest hour of the day, do the stations around it reach their own busiest hours at the same time? Reads the peak_hour_co_saturation claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

poi

poi_context

What kind of place is this site sitting in? Reads the poi_context claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading. places carries the rows this claim reads, because they are transcribed by the caller rather than fetched.

rank

rank_gap

Where does this site sit in its estate's ranking, and how far is it from the estate median and the estate leader? Reads the rank_gap claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print.

Reads the road_context claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

sessions

sessions_per_stall_day

How hard is each EVSE at this site working per day? Reads the sessions_per_stall_day claim for one site and returns only its result: the status the claim decided from its own observations (computed or insufficient), the typed result, and the display a deliverable would print. The observations behind it are pulled into a scratch directory that is deleted before the call returns, so the rows never enter the conversation and nothing is left on the server to read back later — this call is the whole reading.

Tern EV-Charging Analytics — questions

Answers built from our own checks of this server.

What can Tern EV-Charging Analytics do?

It exposes 26 tools, read directly from the server on our last check. Among them: aggregate_charging_utilization, aggregate_evse_utilization, area_benchmark, avg_session_minutes, busy_evse_hours, corridor_benchmark and 20 more. 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 →

What is Tern EV-Charging Analytics mostly used for?

Its tools cluster around site, estate and aggregate. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Tern EV-Charging Analytics 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 465 ms. The bar chart above shows every period we have measured.

How do I connect Tern EV-Charging Analytics?

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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Tern EV-Charging Analytics?

No API key is involved. Tern EV-Charging Analytics answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Tern EV-Charging Analytics?

It answers our handshake in 465 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
