An API key from OpenAI, Anthropic, or Google Gemini is required for LLM-based extraction. Beyond that, no additional API keys are needed. Each MCP runs locally on your machine. Your IP, your requests — no proxy infrastructure, no rate limiting concerns.

You'll need two things installed before starting:
Python 3.10+ — download from python.org or install via brew install python@3.12
An LLM API key — from OpenAI, Anthropic, or Google AI Studio
Then run these commands in your terminal:
# 1. Clone the repo
git clone https://github.com/ekas-io/open-sales-stack.git
cd open-sales-stack
# 2. Run setup (installs everything and prompts you to choose your LLM provider)
bash scripts/setup.sh
# 3. Verify your setup
bash scripts/verify.sh
# 4. Add all MCPs to Claude
bash scripts/add-to-claude.sh --allBy default, the script adds MCPs to Claude Code if the claude CLI is available, otherwise to Claude Desktop. You can override this:
bash scripts/add-to-claude.sh --all --desktop # force Claude Desktop
bash scripts/add-to-claude.sh --all --code # force Claude CodeThe setup script will ask you to choose between OpenAI, Anthropic, or Gemini and prompt for your API key. It configures everything in .env automatically.
If you want to change the default model later, edit the LLM_PROVIDER value in your .env file. See .env.example for supported format.
During setup, you'll also be asked how you'd like to authenticate with LinkedIn (for social-intel):
Skip (default) — configure later; company scraping works without login
Browser login — a browser window opens, you log in manually
Credentials — provide your email + password, saved locally for headless login
See the social-intel README for more details.
If you only want specific MCPs:
bash scripts/add-to-claude.sh --website-intel --social-intel --hiring-intelOnce added, ask Claude:
"What MCP tools do you have access to?"
You should see your installed tools listed.
Each MCP is independent — use one or use all. But they're designed to chain naturally in Claude. Here's what a typical company research flow looks like:
You: "Research Acme Corp for me"
Claude calls: website-intel → scrapes acmecorp.com, extracts product info, pricing, team
Claude calls: techstack-intel → detects they use HubSpot, Drift, Segment
Claude calls: hiring-intel → finds 3 open SDR roles on their Greenhouse page
Claude calls: social-intel → finds their VP Sales on LinkedIn, pulls bio and recent posts
Claude calls: review-intel → pulls G2 rating (4.2/5, 47 reviews), Glassdoor sentiment
Claude calls: ad-intel → 12 active LinkedIn ad campaigns, 5 on Meta
Claude calls: funding-intel → Series B, $24M raised, led by Accel
Claude calls: firmographic-intel → 320 employees, 40% headcount growth YoY
Claude calls: news-intel → 3 recent press mentions, product launch last month
Claude: "Here's what I found about Acme Corp..."You don't need to orchestrate this. Claude reads the tool descriptions and decides which to call based on your request.
Skills are instruction files that teach Claude how to use research data for sales workflows. Drop them into your Claude project knowledge or reference them in prompts.
Skill | What it teaches Claude |
Evaluate whether a company matches your ICP based on research signals | |
Full account + contact level research methodology | |
Read a prospect's LinkedIn profile and posts for outreach signals | |

MCPs get the data. Skills tell Claude what to do with it.

Scrape or crawl a webpage and extract structured data as JSON using a custom schema. Use this tool when you know the specific URL of a website and need to extract particular information in a well-defined, structured format.
Two modes are available: • 'scrape' (default) — single-page extraction with full JS rendering. • 'crawl' — multi-page extraction that follows links up to a page limit.
You MUST provide three things:
The target URL
A JSON Schema object defining the exact shape of the data you want returned
A natural-language prompt describing what to extract
Inputs: url (required), prompt (required), schema (required), mode, +1 more. Returns: result
Recent tool additions, removals, and schema changes observed during successful MCP inspections.

Scored across 1 tool
With only one tool, there is no possibility of ambiguity or confusion. The tool's purpose is clearly defined.
The single tool uses a clear snake_case name that follows a verb_noun pattern, which is consistent and readable.
The server is named 'open-sales-stack', implying a broad sales automation toolkit, but provides only a single web scraping tool. This is a severe mismatch between scope and tool count.
The server offers only webpage extraction, leaving out essential sales stack functionalities such as lead management, CRM integration, or deal tracking. The tool surface is severely incomplete for the implied domain.
