## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_grid_connection`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check nearest UK electricity Distribution Network Operator (DNO) grid
connection headroom for a location — generation/demand headroom (MW/MVA),
RAG status, voltage, and a combined BNG+grid siting signal. Covers all of
Great Britain (England/Scotland/Wales), not just England. Free, no key.
```

### `estimate_bng_cost`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Estimate the cost of meeting England's mandatory 10% biodiversity net
gain requirement for a development scheme of `scheme_ha` hectares, across
3 procurement routes (off-site habitat bank mosaic, off-site grassland/
heathland, statutory biodiversity credits, priced per unit at two Defra
credits per unit), and the units to buy from a gain site in the same, a
neighbouring or a further authority (spatial risk multiplier 1.0 / 0.75 /
0.5, with this point's authority names). land_type: brownfield /
arable / improved / semi_improved / mixed. England only. Free, no key.
```

### `estimate_bng_income`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Estimate 30-year lump-sum BNG income (LOW/MID/HIGH) for dedicating
`area_ha` hectares of an England parcel to biodiversity net gain habitat
creation, from LandBNG planning assumptions per habitat capped at the
Defra statutory credit price; local factors (flood zone, SSSI, Green Belt,
NSIP demand, Ancient Woodland, AONB, Agricultural Land Class) are listed,
not priced. England only. Free, no key.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `check_planning_history`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find planning applications near a UK location, via UK PlanIt's public
aggregator (over 400 UK planning authorities). Free, no key. radius_km must be
between 0.1 and 5.0.
```
