## Changes things (10)

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

### `fetch_email`

- The name "fetch_email" says "fetch": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Look up the verified professional (work) email for a person you have already unlocked with find_people (or reveal_profile). Pass their `id`. Spends 1 credit, refunded automatically if no email is found. The lookup is live: if it returns emailStatus 'searching', call fetch_email again with the same id (no extra charge) to collect the result once it resolves. Returns a professional address, never a personal one; not every person has a findable work email.
```

### `find_company_emails`

- The name "find_company_emails" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Given a company domain or name, return the contactable role-based email addresses discovered for that organization (such as contact@, sales@, support@), each with a confidence level. Use this for reaching a company inbox, not a specific named person (for a named person use find_people or find_linkedin_profile). Spends 2 credits, refunded if none are found.
```

### `find_linkedin_profile`

- The name "find_linkedin_profile" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Find the LinkedIn profile URL for a named person. Provide their first and last name; adding the company or domain sharply improves the match. Spends 2 credits, refunded if no confident match is found.
```

### `find_people`

- The name "find_people" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The list-building tool. Runs a people search exactly as people_search does (the same `filters` or `query`, including its automatic broadening, reported in `broadenedBy`) and unlocks up to `count` full profiles in ONE atomic charge: 1 credit per newly unlocked person, and anyone you already own is free. Pass the same filters you checked with people_search, so you pay for the people you saw. Returns each person's real name, title, company, location, LinkedIn URL and an `id`. Emails are NOT fetched here (that is a separate credit): after unlocking, call fetch_email with each person's `id` to get their verified work email. WARNING for autonomous use: this can spend up to `count` credits in a single call, so choose `count` deliberately and confirm with the user before large batches. Returns an out-of-credits error instead of overspending.
```

### `find_work_email`

- The name "find_work_email" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Find and verify the professional (work) email of a person you can name: give their first name, last name and the company they work at (its domain, such as acme.com, matches best; a company name also works). Returns the address with a confidence label (Verified or Likely) and their LinkedIn profile when it can be matched. Spends 2 credits, refunded automatically if no email is found. People who asked to be removed from PeopleSearch.im are never looked up. To find people you cannot name yet, use people_search or find_people, then fetch_email.
```

### `lookup_company`

- The name "lookup_company" says "lookup": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turn a LinkedIn company URL into firmographic data: industry, size, location and website. Spends 1 credit, refunded if the company cannot be retrieved.
```

### `lookup_linkedin_profile`

- The name "lookup_linkedin_profile" says "lookup": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turn a LinkedIn profile URL into clean structured data: name, current role and company, and location. Spends 2 credits, refunded if the profile cannot be retrieved.
```

### `reveal_profile`

- The description's first verb is "unlock": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Unlock ONE person from a people_search result. Pass the `token` from that result. Spends 1 credit and returns the full profile: real name, current title and company, location and LinkedIn URL. Set `include_email` to true to also look up their verified professional (work) email in the same call, which spends 1 more credit that is refunded if no email is found. Revealing the same person again is free (idempotent). The email is looked up live and may take a moment: if it returns emailStatus 'searching', call reveal_profile again with the same token (no extra charge) to collect it.
```

### `reverse_email_lookup`

- The name "reverse_email_lookup" says "lookup": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turn a professional email address into the real person behind it and their LinkedIn profile. Best for work emails; free-mailbox addresses often have no public profile to match. Spends 13 credits (this is the single most expensive lookup), refunded automatically if no match is found.
```

### `verify_email`

- 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 whether an email address exists and is safe to send to, before it bounces. Returns a deliverability verdict (deliverable, undeliverable, or unknown) without sending anything. Spends 1 credit, refunded if no verdict can be reached.
```

## Only reads (3)

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

### `check_credits`

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

Description, as the server wrote it:

```untrusted-server-text
Return the current credit balance for the API key making the request. Free and read-only. Use it before a large find_people call to confirm there are enough credits.
```

### `company_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search a global company database and get matching companies with industry, size, location and website. Three ways to ask: a company's website ('warmly.ai') returns that one company, the most exact way to identify one; a company's name ('Warmly') returns the companies of that name; a description in plain English ('Series B fintech companies in London with 50-200 employees') returns the companies that fit it. Searching companies is FREE and spends no credits. It also works before a PeopleSearch.im account is connected: without one it returns up to 3 companies per search, up to 10 searches a day.
```

### `people_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search a global professional database for people and get a sample of matches plus the true total match count. Ask with `filters` (recommended: state each part exactly, for example {"job_titles": ["M&A Associate", "Investment Banking Associate"], "locations": ["Frankfurt", "Munich"], "industries": ["Investment Banking"], "schools": ["University of Mannheim"]}) or with `query`, a plain-English sentence that is parsed for you (for example 'Heads of Marketing at Series B SaaS in New York'). Results are masked previews (a masked name, role, industry, company size and location) and each one carries an opaque `token`. Searching is FREE and spends no credits: use it to check that the right people come back before you pay, and refine the filters if they do not. To look up one named person, give `first_name` and `last_name` with their company or company domain when known. For a kind of employer no industry names exactly, use `company_keywords` (words its own description contains, for example ["hostel"] or ["SEO"] with industries ["Marketing Services"]). If nothing matches exactly, the search broadens itself: a job title is read more broadly first (`broadenedRole` gives the title as asked and as searched), then the least essential filters are dropped and `broadenedBy` names them; `ignored` lists any filter that could not be applied. To get a person's real name, LinkedIn and verified email, pass their token to reveal_profile, or use find_people with the same filters to unlock a batch in one call. It also works before a PeopleSearch.im account is connected: without one it returns up to 3 previews per search, up to 10 searches a day.
```
