Which integrations are available for this server?

Provides tools for payment management, including generating a Stripe checkout URL to add a card and charging a saved card to top up credits.

Potarix MCP Server

MCP wrapper for Potarix Enricher. Lets AI agents resolve company websites, find verified emails, and pull complete company rosters — and (with one human-in-the-loop card capture) sign up and pay for credits entirely from the agent.

Tools

tool	what it does	cost
`lookup_company_website`	company name → website URL	2 credits
`find_person_email`	named person + company/domain → verified email	25 credits
`find_decision_maker_email`	category + domain → likely buyer name + email	25 credits
`find_linkedin_email`	LinkedIn profile URL → verified email	10 credits
`find_company_emails`	domain → public company contact roster	25 credits
`find_all`	one company name → website + DMs + full company email list	sum of above
`check_balance`	credits, email, saved-card status, key count	free
`start_checkout`	get a Stripe URL to add a card the first time	n/a
`topup_credits`	charge the saved card and add credits	n/a

1 credit = $0.01. Trial accounts start with 25 free credits. Every endpoint floors at the worst-case provider COGS — a hit never loses money, and short-circuited waterfall calls earn margin.

Two ways to connect

transport	endpoint	best for
Streamable HTTP (hosted)	`https://api.potarix.com/mcp`	remote agents (Claude, ChatGPT) — no install
stdio (npm package)	`npx -y potarix-mcp`	local/desktop clients

Both expose the same nine tools. The hosted server is stateless and multi-tenant: every request is authorized by its own Authorization: Bearer ptk_live_... header, so there is no per-user deployment.

Hosted (Streamable HTTP)

Point any MCP client that speaks Streamable HTTP at https://api.potarix.com/mcp and send your key as a bearer token:

{
  "mcpServers": {
    "potarix": {
      "url": "https://api.potarix.com/mcp",
      "headers": { "Authorization": "Bearer ptk_live_your_key" }
    }
  }
}

Install (stdio)

npm install -g potarix-mcp

Or run it without a global install:

npx -y potarix-mcp

Configure

Set your Potarix API key:

export POTARIX_API_KEY=ptk_live_your_key

Optional:

export POTARIX_API=https://api.potarix.com/enricher

Claude Code

claude mcp add potarix npx -- -y potarix-mcp

Then add POTARIX_API_KEY to the environment where Claude Code runs.

Development

npm install
npm run build
npm run smoke        # stdio transport: connect + tools/list

# Streamable HTTP transport:
npm run start:http   # serves on http://127.0.0.1:8080/mcp (set PORT to change)
# in another shell:
POTARIX_MCP_URL=http://127.0.0.1:8080/mcp npm run smoke:http

Environment variables:

var	default	purpose
`POTARIX_API_KEY`	—	API key (stdio only; HTTP reads it per-request from the bearer header)
`POTARIX_MCP_TRANSPORT`	`stdio`	`http` to run the Streamable HTTP server (or pass `--http`)
`PORT` / `HOST`	`8080` / `127.0.0.1`	HTTP bind address
`POTARIX_MCP_PATH`	`/mcp`	HTTP request path
`POTARIX_MCP_ALLOWED_HOSTS`	—	comma-separated host allow-list; enables DNS-rebinding protection
`POTARIX_API`	`https://api.potarix.com/enricher`	API base URL override
