Plain-English people search with verified work emails, email verification and LinkedIn lookup.
PeopleSearch.im is a remote MCP server published at peoplesearch.im. It has been probed 7 times since 9/12/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 1,673 ms, a delay an agent will notice. It offers a narrow, focused set of 12 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
people_search — Description truncated mid-sentence with 'o'reveal_profile — Description cut off mid-sentence with 'whic'find_people — Functionally overlaps with people_searchfind_linkedin_profile — Similar purpose to lookup_linkedin_profile but different parameterstools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
people_searchSearch a global professional database in plain English (for example 'Heads of Marketing at Series B SaaS in New York') and get a sample of matching people plus the true total match count. 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 validate that the right people exist before you pay. To get a person's real name, LinkedIn and verified email, pass their token to reveal_profile, or use find_people to unlock a batch in one call.
querystringrequiredlimitintegerreveal_profileUnlock 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.
tokenstringrequiredinclude_emailbooleanfind_peopleThe list-building tool. Re-runs a plain-English people search and unlocks up to `count` full profiles in ONE atomic charge: 1 credit per newly unlocked person, and anyone you already own is free. 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.
querystringrequiredcountintegerfetch_emailLook 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.
profile_idstringrequiredverify_emailCheck 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.
emailstringrequiredfind_company_emailsGiven 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.
domain_or_companystringrequiredreverse_email_lookupTurn 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.
emailstringrequiredfind_linkedin_profileFind 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.
first_namestringrequiredlast_namestringrequiredcompany_or_domainstringlookup_linkedin_profileTurn 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.
linkedin_urlstringrequiredlookup_companyTurn a LinkedIn company URL into firmographic data: industry, size, location and website. Spends 1 credit, refunded if the company cannot be retrieved.
linkedin_company_urlstringrequiredcompany_searchSearch a global company database in plain English (for example 'Series B fintech companies in London with 50-200 employees') and get matching companies with industry, size, location and website. Searching companies is FREE and spends no credits.
querystringrequiredcheck_creditsReturn 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.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
