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.

Input	Type	Required	Notes
`sequencer`	string	yes	`instantly`, `smartlead` or `heyreach`. HeyReach is LinkedIn native and keys a lead on `linkedin_person_url` rather than on email
`campaign_id`	string	yes	The target campaign. It must already exist. Instantly campaign IDs are UUIDs; Smartlead and HeyReach campaign IDs are numeric.
`api_key`	string	see note	Your Instantly v2 key, your Smartlead key, or your HeyReach key
`leads`	array	one of	Lead rows. Each needs an `email` at minimum, or a `linkedin_person_url` on HeyReach.
`dataset_id`	string	one of	An Apify dataset ID from an upstream run
`min_icp_score`	number	no	Drop leads scoring below this. Default 0.
`deduplicate`	boolean	no	Check the campaign first. Default true.
`dry_run`	boolean	no	Preview without sending. Default false.
`field_mapping`	object	no	Override the default column map
`custom_variables`	array	no	Extra columns to pass through
`max_charge_usd`	number	no	Optional 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.

Event	Price (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

Sequencer	API	Notes
Instantly	v2	Needs a v2 key. Keys from v1 do not work: Instantly deprecated v1 on January 19, 2026.
Smartlead	v1	Current. Smartlead has no v2.
HeyReach	public API	LinkedIn 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.
