People Data

Overview

Perform authorized professional-profile and public business-contact research through the Agent Body MCP server at /mcp/people-data. It covers LinkedIn profile retrieval, email and phone lookup, filtered people search, and YouTube channel business-email discovery.

Read [references/tool-reference.md](references/tool-reference.md) for exact tool names and input fields.

When to Use This Skill

• Use when the user asks to look up, enrich, or verify a LinkedIn professional profile.
• Use when the user needs a business email or phone number for a LinkedIn profile they are authorized to contact.
• Use when the user wants to find people by role, company, location, seniority, or other LinkedIn filters.
• Use when the user wants to find public business contact emails for YouTube channels.
• Use when the user asks to validate or deduplicate people-search results before outreach.

How It Works

Step 1: Choose one operation

• linkedin_person_profile with linkedin_url retrieves one professional profile.
• linkedin_email_lookup with profileUrl looks up one profile email address.
• linkedin_phone_lookup with profileUrl looks up one profile phone number.
• linkedin_people_search accepts optional filters and returns a nextPageToken for continuation.
• youtube_email_finder takes channels (1-1000 channel URLs) and optional scrape_fresh_emails to find public business emails.

Step 2: Prefer canonical URLs and explicit filters

Use canonical profile or channel URLs when available. For name-only searches, add explicit role, company, location, or keyword filters. companyFilter must be current, past, or all.

Step 3: Verify and present only returned data

Confirm that returned identities match the request, deduplicate search results by canonical profile identity, and never construct or guess an email address or phone number. Preserve per-channel found/not-found state from YouTube results.

Examples

Example 1: Look up one LinkedIn profile

Call linkedin_person_profile with:

{
  "linkedin_url": "https://www.linkedin.com/in/example-person"
}

Example 2: Find public business emails for YouTube channels

Call youtube_email_finder with:

{
  "channels": ["https://www.youtube.com/@example"],
  "scrape_fresh_emails": false
}

Best Practices

• ✅ Use canonical profile or channel URLs instead of guessing handles.
• ✅ Confirm the returned identity matches the person or channel before presenting it.
• ✅ Use only public, authorized, or explicitly permitted business data.
• ✅ Keep nextPageToken unchanged when continuing a linkedin_people_search.
• ❌ Do not fabricate, guess, or infer email addresses or phone numbers.
• ❌ Do not bypass access controls or collect private profiles without authorization.

Limitations

• Requires an Agent Body API key and access to the /mcp/people-data MCP server; results depend on the live tool schema.
• Email and phone lookup may return no result for profiles without public contact data; a missing result is not evidence that a person has no contact information.
• Search filters are optional, but unfiltered name-only searches can return ambiguous matches that need manual verification.
• youtube_email_finder only finds public business emails and may report channels where no email is found.

Security & Safety Notes

• Never print, log, or commit API keys or other credentials.
• Use contact information only for authorized business purposes and respect privacy, anti-harassment, and outreach rules.
• Do not use this skill to build contact lists without a lawful basis or to contact people who have opted out.
• This skill is read-only: it queries business data and does not modify files or systems.

Common Pitfalls

• Problem: Using the wrong input key for profile versus email/phone lookups.

Solution: Profile lookup uses linkedin_url; email and phone lookup use profileUrl.

• Problem: Guessing an email when lookup returns nothing.

Solution: Report the missing result and stop; never invent contact data.

• Problem: Repeating the same people-search page.

Solution: Pass the returned nextPageToken unchanged to continue instead of replaying the initial query.
