## Findings

- **warn** Annotations that disagree with the tool in `pdl_person_search` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "pdl_person_search" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true}; The name "pdl_person_search" says "search": a word for reading.
```

- **warn** Annotations that disagree with the tool in `pdl_company_search` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text

## Changes things (5)

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

### `pdl_company_search`

- The name "pdl_company_search" says "search": a word for reading.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Search the full PDL Company Dataset with an Elasticsearch query object OR a SQL string over the Company Schema (e.g. all SaaS companies with 50-200 employees in the US). Paginate with scroll_token. Each returned record costs 1 credit. API: POST /company/search.
```

### `pdl_ip_enrich`

- 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
Enrich an IP address with its location, company, and (optionally) associated person data via a 1:1 match against PDL's IP dataset. API: GET /ip/enrich.
```

### `pdl_job_posting_search`

- The name "pdl_job_posting_search" says "search": a word for reading.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Search PDL's Job Posting Dataset (millions of active & historical postings sourced from company career pages) with an Elasticsearch query object OR a SQL string. Beta — may require plan access (HTTP 403 if not enabled). Each returned posting costs 1 credit. API: POST /job_posting/search.
```

### `pdl_person_identify`

- 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
Given broad, possibly-ambiguous attributes about a person, return up to 20 strongly-related profiles ranked by match score. Sits between enrich (1:1) and search (open-ended) — ideal when you can't uniquely resolve someone. API: GET /person/identify.
```

### `pdl_person_search`

- The name "pdl_person_search" says "search": a word for reading.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Search the full PDL Person Dataset with an Elasticsearch query object OR a SQL string over the Person Schema (e.g. everyone with job_title_role='engineering' at a company). Returns matching profiles sorted by completeness; paginate with scroll_token. Each returned record costs 1 credit. API: POST /person/search.
```

## Only reads (3)

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

### `pdl_autocomplete`

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

Description, as the server wrote it:

```untrusted-server-text
Get suggested values for a search field along with the number of available records for each — useful for building valid Person/Company Search queries. Free on all plans. API: GET /autocomplete.
```

### `pdl_company_enrich`

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

Description, as the server wrote it:

```untrusted-server-text
Find the single best-matching company record. Requires a non-ambiguous input — name OR website OR ticker OR profile (website/ticker/profile resolve more reliably than name). Returns firmographics (industry, size, location, etc.) or a 404 'no match' body. API: GET /company/enrich.
```

### `pdl_person_enrich`

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

Description, as the server wrote it:

```untrusted-server-text
Find the single best-matching person profile for a set of identifying attributes (name, email, phone, profile URL, company, etc.). Returns one record plus a likelihood score (1-10), or a 404 'no match' body. Use uniquely-identifying inputs for best results. API: GET /person/enrich.
```
