No check matched anything in these tool definitions.


## Changes things (2)

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

### `expiring_contracts`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Awarded service and supply contracts whose term ends within the next months according to the notice (end date or duration, without renewals), with winner, renewals and offers. A new tender is likely but not certain. Needs at least gewerk, land or buyer.
```

### `market_stats`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Market of one trade in Germany, a Bundesland or a Kreis: tenders in the last 12 months, open now, median offers per award, share with a single offer, typical award sums (quartiles) and frequent winners.
```

## Only reads (6)

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

### `find_organisations`

- The name "find_organisations" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find contracting authorities (Vergabestellen) and companies by name or its beginning, e.g. "Stadt Köln", "Fraunhofer", "WISAG". Returns name, city, slug and page URL for get_buyer and get_company_awards, the most active first. Only organisations with a page in the index; sole traders are never listed.
```

### `get_buyer`

- The name "get_buyer" says "get": a word for reading.
- Tag private-data: The description's first sentence says "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
A contracting authority (Vergabestelle): contact data from one of its notices (no persons; may belong to a law firm or central purchasing body that runs procedures for it, for a procedure use the contact in its notice), platforms, open tenders, recent awards, offers per award, frequent winners, trades and contracts that end soon.
```

### `get_company_awards`

- The name "get_company_awards" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Contracts won by a company (legal entities with a page on vergabeweiser.de/unternehmen only, never sole traders): totals, buyers, Länder, trades and the awards, 25 per page, with the company's published sum. firm_shared_max: an amount the notice gives alike for several winners of a lot (usually a shared framework ceiling); not counted as the company's sum or share.
```

### `get_tender`

- The name "get_tender" says "get": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
One tender: description, all deadlines (Bieterfragen, Teilnahmeantrag, Angebotsfrist), procedure, lots, result with winners, sums and number of offers, link to the documents on the buyer's platform and to the original notice. result.framework_max is the ceiling of a framework agreement for all call-offs, not an award sum: never report it as the contract value or a firm's share.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Slugs of all trades (Gewerke) and Bundesländer for the other tools.
```

### `search_tenders`

- The name "search_tenders" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search German public tenders like vergabeweiser.de/suche. Free text in German may contain a trade and a place ("Gebäudereinigung Rosenheim", "Dach 25 km um 90402"). Returns 20 results per page with deadline, buyer, place, estimated value and the page URL. result.framework_max is the ceiling of a framework agreement, never an award sum.
```
