Sequencer Lead Push MCP Server

MCP server for the Mamba Labs Sequencer Lead Push actor on Apify.

Push enriched lead rows into an existing Instantly, Smartlead, or HeyReach campaign. ICP score gating and deduplication are built in, and a dry run shows you the exact payload before you send anything.

Install

npx -y @mambalabsdev/mcp-clay-to-instantly-smartlead-push

Tool

push_leads_to_sequencer

Maps your column names onto the sequencer's field names, drops leads below your ICP score threshold, drops leads already in the campaign, and sends the rest in batches.

InputTypeRequiredNotes
sequencerstringyesinstantly, smartlead or heyreach. HeyReach is LinkedIn native and keys a lead on linkedin_person_url rather than on email
campaign_idstringyesThe target campaign. It must already exist. Instantly campaign IDs are UUIDs; Smartlead and HeyReach campaign IDs are numeric.
api_keystringsee noteYour Instantly v2 key, your Smartlead key, or your HeyReach key
leadsarrayone ofLead rows. Each needs an email at minimum, or a linkedin_person_url on HeyReach.
dataset_idstringone ofAn Apify dataset ID from an upstream run
min_icp_scorenumbernoDrop leads scoring below this. Default 0.
deduplicatebooleannoCheck the campaign first. Default true.
dry_runbooleannoPreview without sending. Default false.
field_mappingobjectnoOverride the default column map
custom_variablesarraynoExtra columns to pass through
max_charge_usdnumbernoOptional cost cap in USD for this run. The actor stops before an item that could take its charges past this amount. Omit to rely on the maximum cost per run set in Apify.

api_key is required for any run that calls the sequencer. A dry run with deduplicate false makes no calls at all and needs no key.

Returns one flat summary row: leads received, dropped for no usable identity (an email, or a LinkedIn profile URL on HeyReach), dropped by the ICP gate, dropped as duplicates, eligible, created by the sequencer, skipped by the sequencer, and failed, with the vendor's own message per failed address.

Dry run

dry_run: true runs every step, returns the exact request batches that would have been sent, and creates nothing. Nothing is billed.

Use it the first time you point at a new campaign. The payload you see is the real one, and your API key is never included in it.

Billing

You are charged per lead the sequencer confirms it created. Leads dropped by the gate, dropped as duplicates, with no usable email, skipped or rejected by the vendor, and every lead in a dry run are all free.

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

EventPrice (USD)
Actor Start (apify-actor-start)0.00005
Lead pushed to sequencer (lead-pushed)0.01

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

Supported sequencers

SequencerAPINotes
Instantlyv2Needs a v2 key. Keys from v1 do not work: Instantly deprecated v1 on January 19, 2026.
Smartleadv1Current. Smartlead has no v2.
HeyReachpublic APILinkedIn native. Keys a lead on linkedin_person_url, so rows with no LinkedIn profile URL are dropped and rows with no email are kept.

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. The field mapping, the ICP gate, the deduplication and everything each vendor's API needs all live in the actor, not here.

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.

It writes to your sequencer campaign unless dry_run is true. It does not create campaigns and it does not write sequence copy.

Part of the Mamba Labs GTM actor fleet. The same tool is available alongside twenty others in @mambalabsdev/mcp-gtm-suite.
