Prospect Engine MCP Server

MCP server for the Mamba Labs Prospect Engine actor on Apify.

Four modes in one actor: enrich companies you already have, discover who is hiring for your keywords, find contacts at a company, or run the whole chain end to end with an ICP gate in the middle.

Tool

run_prospect_engine

Four modes in one actor: enrich companies you already have, discover who is hiring for your keywords, find contacts at a company, or run the whole chain end to end with an ICP gate in the middle.

InputTypeRequiredNotes
modeenumnoWhat to run. enrich_companies resolves identity, firmographics, LinkedIn and social for each company. discover_jobs finds who is hiring for your keywords and resolves the real employer from the job description. find_contacts finds people at each company. full chains all three. Default: "enrich_companies". One of: enrich_companies, discover_jobs, find_contacts, full.
domainsarraynoOne domain per line. Used by enrich_companies and find_contacts.
company_namesarraynoOne name per line. Used when you have a name but no domain.
keywordsarraynoRoles to search for. Used by discover_jobs and full. Example: copy editor, proofreader, content editor. Default: ["copy editor", "proofreader", "content editor"].
countrystringnoTwo letter country code for job search, for example us or gb. Default: "us".
locationstringnoOptional location filter for job search, for example New York.
lookback_daysstringnoDrop postings older than this many days. Sent as a string because Clay sends every field as a string. Default: "30".
max_resultsstringnoCap on postings returned per run. Keeps a broad keyword set from running away. Default: "25".
max_pagesstringno1 to 5. Each page is one SerpAPI call, so this is the main cost dial on discovery. Default: "1".
new_postings_onlystringnotrue to return only postings not seen in a previous run. Default: "false".
previous_run_datestringnoYYYY-MM-DD watermark for delta detection when the cross-run cache is unavailable.
remote_onlystringnotrue to keep only postings flagged remote by the board. Default: "false".
company_size_minstringnoDrop companies below this headcount. Only takes effect once headcount is known, so it applies in full mode and to any discovery row that carried an employee count. Discovery alone does not enrich.
company_size_maxstringnoDrop companies above this headcount. Same condition as the minimum.
exclude_staffingstringnotrue to drop postings from staffing and recruitment agencies. Default: "true".
exclude_marketplacesstringnotrue to drop Upwork, Fiverr, Freelancer and similar gig listings. Default: "true".
extra_marketplacesarraynoAdditional marketplace names to filter out.
fetch_posting_pagestringnotrue to open the job posting when the description alone does not identify the employer. Slower, and it is what catches a job board posting on an employer's behalf. Default: "true".
target_contactsstringno1 to 25. Default: "3".
target_rolesarraynoOnly enrich contacts whose title plausibly matches one of these roles. Filters after discovery and before any paid email lookup, so a non-matching contact costs nothing. Leave empty to keep every contact the seniority and department filters allow.
deny_tokensarraynoWhole words that disqualify a contact even when the title matched a target role, for example product refuses Product Owner and keeps Production Editor. Applies even when no target roles are set.
company_concurrencystringnoHow many companies to work at once. Simultaneous provider calls are this times contact_concurrency; 6 x 3 = 18 sits under the tightest documented provider ceiling. Default: "6".
contact_concurrencystringnoHow many contacts to enrich at once within one company. The email waterfall itself always runs in order. Default: "3".
max_spend_usdstringnoStop making paid vendor calls once this much of your own vendor spend (Findymail, Icypeas, Prospeo, BounceBan) is committed, and return everything completed so far. Caps your vendor bills, not the Apify charge for this actor. Leave empty for no cap.
max_charge_usdnumbernoYour cap on this actor's Apify charge for the run, in USD. A charge that would cross it is not made, the run stops, and one notice row says so. Separate from max_spend_usd, which caps your own vendor bills.
job_titlesarraynoTitles to search for when finding contacts.
seniorityarraynoc_level, vp, director, manager, senior.
departmentsarraynomarketing, sales, engineering, product, finance, hr, operations, legal.
include_emailstringnotrue to run the email waterfall. Needs an Icypeas or Prospeo key, which you supply and are billed for directly. Default: "false".
verify_emailstringnotrue to verify each address. Needs a BounceBan key. Default: "true".
verify_positionstringnotrue to ask a model whether each contact's title on record is consistent and plausibly current, from the supplied evidence only. Needs claude_api_key; skipped without it. Contacts found on the company's own website are skipped. Default: "true".
personalizestringnotrue to write a one or two sentence opener per contact that has an address, referencing something specific about the company. Needs claude_api_key; skipped without it. Default: "true".
brand_voicestringnoHow the opener should sound. Leave empty and it writes plainly and directly.
score_icpstringnotrue to score every row against the ICP rules and tier it A to D. Default: "true".
icp_presetenumnoWhich scoring model to apply. "editorial_services" scores for a seller of managed copy editing and proofreading. "generic_b2b" scores on hiring intent, employer resolvability and headcount with no service-specific vocabulary. Default: "editorial_services". One of: editorial_services, generic_b2b.
min_icp_scorestringnoIn full mode, only companies scoring at or above this go on to contact discovery. Default 45: at 25 the filter passed every keyword-discovered editorial posting, because 25 is the floor such a posting can score. Default: "45".
extra_exclude_namesarraynoAny company whose name contains one of these is excluded.
signal_taxonomyarraynoOverride the default signal types. Each entry is an object with type, strength, title_keywords, and optional also_keywords and description_keywords.
include_socialstringnotrue to resolve Facebook, Instagram, X and YouTube alongside LinkedIn. Default: "true".
source_timeout_secsstringno5 to 120. A source that exceeds this is marked degraded and the run continues. Default: "30".
skip_cachestringnotrue to ignore the 7 day cross-run cache and recompute everything. Default: "false".
serper_api_keystringnoYour Serper.dev key. Powers people search in find_contacts, which is the highest-coverage layer. Without it the free fallback is measurably poor.
findymail_api_keystringnoYour Findymail key. First provider in the email waterfall.
icypeas_api_keystringnoYour Icypeas key. Runs on Findymail misses.
prospeo_api_keystringnoYour Prospeo key. Runs on the residual after Findymail and Icypeas.
bounceban_api_keystringnoYour BounceBan key. Second verifier, used for the catch-all case.
serpapi_keystringnoYour SerpApi key. Required by discover_jobs and full. Distinct from a Serper key: different vendor.
claude_api_keystringnoYour own Anthropic key, used for position verification and the personalized opener. Both steps are skipped when it is absent. Never stored.

Billing

You are charged per company enriched, per contact verified and per job posting discovered, at different rates for basic and full enrichment. Vendor API calls are billed to you by those vendors directly. Set max_spend_usd to cap that vendor spend per run, and target_roles to skip paid lookups for contacts outside the roles you want. verify_position and personalize run on your own Anthropic key (claude_api_key) and are skipped without it.

Price per event on the Apify FREE plan, from the live pricing record; paid Apify plans pay less per event.

Pricing is on the actor's Apify page. Running this server consumes Apify credits.

What this server does and does not do

It is a thin client for the Apify actor. It passes your input through and returns the actor's output unchanged. Every behavior described above lives in the actor, not here.

Errors are surfaced, never swallowed. An invalid input, an invalid token, an exhausted balance, a timeout, or a run that returns anything other than a dataset all come back as an explicit tool error rather than as an empty result.

The tool starts the actor run and polls it to a finished status, so a long run is not cut off at 300 seconds. The run is allowed 1,800 seconds. If it is still going two minutes after that, the call stops waiting and returns the run ID with a link to it in the Apify Console, where the results land when it finishes. A run that does not succeed comes back as an error with its run ID and status. A full or find_contacts run over many companies can take several minutes, which is why this matters here.
