Overview

AI-generated overview

Local MCP server that monitors a company domain for hiring, tech stack, funding, firmographic and social changes and returns only deltas since the last run.

What you can do
  • Monitor one or several company domains for changes across hiring, tech stack, funding, firmographics and social presence
  • Return only deltas as typed change events with severity, confidence, old and new values, and the source actor ID
  • Record a baseline on the first run per domain, then diff later runs against the stored snapshot or a supplied previous snapshot
  • Filter results by minimum severity and limit which sources run
  • Cap run cost in USD and set per-source timeouts
When to use it
Useful for RevOps, outbound and account-monitoring work where an assistant should report what changed at target companies since the last check rather than re-describing their current state. Also fits agents that want to keep delta state outside Apify by passing a previous snapshot.
Requirements
Runs locally over stdio via npx, requiring Node.js 18 or newer. Needs an Apify account and an APIFY_TOKEN environment variable; all work is executed by an Apify actor, so network access and Apify credits are required.
Before you install
The APIFY_TOKEN is a paid-account credential passed in the environment. Runs are billed per event on Apify, so cost depends on selected sources and result volume; use max_charge_usd and the sources filter to limit spending. Company domains and monitoring data are sent to Apify. Long runs may return only a run ID and link instead of finished results.

Installation

In SourceWeft

  1. Open Mcp Company Change Event Feed in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

[Company Change Event Feed MCP server]

Company Change-Event Feed monitors a company domain for changes across hiring, tech stack, funding, firmographics, and social presence, then diffs the current state against your last run and returns only what changed as typed change events. Flat, Clay-ready JSON, one row per company, built for RevOps teams, outbound agencies, Clay users, and AI agents that need delta intelligence on target accounts.

What's Inside

What it does

This server gives an AI client one tool:

  • get_company_changes: monitor a company domain for changes across hiring, tech stack, funding, firmographics, and social since the last run. The first run for a domain records a clean baseline (no changes); every run after that returns only the deltas as typed change events, each with a severity, a confidence, an old and new value, and the immutable Actor ID of the source that produced it.

All of the work runs on Apify. This package is a thin client that routes the tool call to the actor and hands back the result.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config:

json
{  "mcpServers": {    "company-change-event-feed": {      "command": "npx",      "args": ["-y", "@mambalabsdev/mcp-company-change-event-feed"],      "env": {        "APIFY_TOKEN": "your-apify-token"      }    }  }}

Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The tool will be available.

Prerequisites

  • Node.js 18 or newer
  • An Apify account with an API token

Example prompts

  • "What changed at stripe.com since the last check across hiring, tech stack, and firmographics?"
  • "Monitor hubspot.com and tell me only the high-severity changes."
  • "Run a baseline for deel.com (company name Deel), then check it next week for deltas."
  • "Did anything change in the GTM signals for notion.so?"

Tool and inputs

get_company_changes:

  • domain (string, required unless domains is set): company domain to monitor, without https or www, e.g. stripe.com.
  • domains (array, optional): batch mode, several company domains in one run with one output row each. When set and non-empty it overrides domain.
  • company_name (string, optional): company name hint, used when the domain does not match the brand name, e.g. Deel for deel.com.
  • sources (array, optional): which sources to monitor: hiring, tech_stack, firmographic, funding, social. Omit for all five. A source you do not select is not run and not charged, so this is the largest lever on cost.
  • min_severity (string, optional): low (default, everything), medium (drops small noise), high (funding, acquisitions, exec moves, CRM changes and large hiring ramps only).
  • previous_snapshot (object, optional): the snapshot object returned by a prior run. Supply it and it is used as the baseline instead of the stored snapshot, so you can hold delta state outside Apify. Ignored in batch mode.
  • sub_actor_timeout_secs (integer, optional): per source run timeout in seconds, 5 to 300, default 300. The sources run in parallel, so total wall time is about the slowest source. Lower it to keep a quick test short.
  • max_charge_usd (optional): a cost cap in USD for this run. The actor stops before an item that could take its charges past this amount. Omit it to rely on the maximum cost per run set in Apify.

sources and sub_actor_timeout_secs are the two controls on how long and how much a call costs: each selected source is one sub actor run.

The output is one row per company: company_domain, company_name, run_date, is_baseline, total_changes, has_high_severity, latest_change_date, a changes array of typed change events, a source_status object (ok / degraded / skipped / not_selected per source), and a snapshot object carrying the current state for the next run's comparison. Each change event has event_type, severity, confidence, old_value, new_value, and the source_actor immutable Actor ID.

The funding source runs the Funding and Press Signal Scanner, so funding, exec move, product launch, and acquisition events are reported like any other source.

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.

Get Company Changes

Monitor a company domain for changes across hiring, tech stack, funding, firmographics, and social since the last run. The first run for a domain records a baseline and reports no changes (is_baseline true); every later run diffs against the stored snapshot, or against previous_snapshot when you pass one, and returns only what changed as typed change events, each with severity, confidence, old and new value, and the source actor ID. One flat Clay-ready row per company, with source_status per source and a snapshot object for the next comparison. Use it on a schedule to watch target accounts for deltas. Do not use it for a one-time profile of a company (the Company Firmographic Enricher or a single source actor is cheaper), because each selected source is one sub actor run. Pass domains for a batch. Requires an APIFY_TOKEN and consumes Apify credits per source run. Reads public data only and writes nothing.
