Overview

AI-generated overview

Hosted BlitzAPI server that lets an assistant search and enrich B2B companies and people, find work emails and US phone numbers, and search job postings.

What you can do
  • Search and enrich people: ICP-based people search, employee lists, waterfall ICP, LinkedIn profile enrichment, work email and US phone lookup, and reverse lookups by email or phone
  • Search and enrich companies: firmographic search, LinkedIn enrichment, domain-to-LinkedIn and LinkedIn-to-domain mapping, TAM lists from job or people filters, and headcount by country or department
  • Search job postings across all companies or within one company
  • Search and read the live Blitz documentation, so an agent can check endpoint bodies and filter values before calling
  • Check account plan, remaining records and rate limits, read the changelog, get the current date, and send feedback
When to use it
Useful for go-to-market, sales and recruiting workflows where an assistant needs to build lead or target-account lists, enrich contacts, or find verified work emails and US phone numbers. Also handy when an agent should look up Blitz API documentation and call endpoints in the same session.
Requirements
A remote streamable HTTP endpoint; no local package. A Blitz account is required: sign in through OAuth on first use, or pass an API key in the x-api-key header. Usage draws on the plan's record allowance.
Before you install
Tools consume paid records from your plan: searches bill per result returned, lookups and enrichments bill on success, so set max_results deliberately. The server handles personal data such as work emails, phone numbers and LinkedIn profiles, and sends queries to a third-party service. If you use an API key instead of OAuth, keep it out of committed config files.

Installation

In SourceWeft

  1. Open BlitzAPI in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.blitz-api%2Fb2b-data/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Skills for Real GTM

This repo is the home of the BlitzAPI MCP server, a hosted remote server that gives agents B2B data: search and enrich companies and people, verified work emails, US phone numbers, job postings, and the live Blitz docs. It also holds the Blitz agent skills.

These skills are designed to be small, easy to adapt, and composable. They work with any model. Hack around with them. Make them your own.

Blitz MCP server

What it does

Search and enrich B2B companies and people: verified work emails, US phone numbers, job postings. The server exposes one tool per Blitz API endpoint, plus tools to search and read the live Blitz docs, so an agent can look up how an endpoint works and call it in the same session. The plugin installs below ship it preconfigured.

URLhttps://api.blitz-api.ai/mcp
TransportStreamable HTTP
AuthOAuth (sign in with your Blitz account) — or an x-api-key header
Registry nameai.blitz-api/b2b-data (MCP Registry)

The committed configs (.mcp.json for Claude Code and Grok, mcp.cursor.json for Cursor) use OAuth and contain no secrets. If you prefer an API key, pass it as a header in your own local config and never commit it, for example claude mcp add --transport http blitz-api https://api.blitz-api.ai/mcp --header "x-api-key: YOUR_API_KEY". Full per-agent setup: Connect Your AI (MCP).

API tools draw on the records in your plan's allowance. Search tools bill per result returned (set max_results to control it); lookups and enrichments bill when they succeed. Request bodies and valid filter values come from the server itself, so ask your agent to run docs_search before building a query.

Account and pricing

A Blitz account is required. Your client opens an OAuth sign-in on first use, so there is no API key to copy. Plans and pricing are on the Blitz website.

Quickstart (30-second setup)

  1. Run the skills.sh installer:
bash
npx skills@latest add api-blitz/skills

  1. Pick the skills you want, and which coding agents you want to install them on.

  2. You're ready to go.

Install by agent

The skills.sh installer above works for Claude Code, Codex, Cursor, and other Agent Skills-compatible agents. The options below also add the Blitz MCP server.

VS Code (GitHub Copilot)

Add the MCP server with the VS Code CLI:

bash
code --add-mcp '{"name":"blitz-api","type":"http","url":"https://api.blitz-api.ai/mcp"}'

Or add it to .vscode/mcp.json in your project:

json
{ "servers": { "blitz-api": { "type": "http", "url": "https://api.blitz-api.ai/mcp" } } }

Start the server and sign in with your Blitz account when VS Code prompts.

Claude Code

Install the plugin (skills + MCP server as one managed install). Inside Claude Code:

bash
/plugin marketplace add api-blitz/skills/plugin install blitz-api-skills@blitz-api

Or from your shell:

bash
claude plugin marketplace add api-blitz/skillsclaude plugin install blitz-api-skills@blitz-api

Then run /mcp, select blitz-api, and sign in with your Blitz account.

Grok

bash
grok plugin install api-blitz/skills --trust

The first Blitz tool call opens OAuth in the browser.

Cursor

Install the skills with the skills.sh installer above, and add the MCP server to mcp.json (Cmd/Ctrl + Shift + P → Open MCP Settings):

json
{  "mcpServers": {    "blitz-api": {      "url": "https://api.blitz-api.ai/mcp"    }  }}

Claude.ai and ChatGPT

Add https://api.blitz-api.ai/mcp as a custom connector (remote MCP server) and sign in with your Blitz account. In Claude.ai: "+" → Manage Connectors → Add custom Connector.

Layout

Skills live under skills/, grouped into buckets:

  • Blitz — skills that wrap Blitz API directly (Waterfall ICP, People/Company Search, enrichment, integration recipes).
  • GTM — general lead-finding scripts, outreach, content, sales motions, analytics, lifecycle automation, and the engineering that powers them.
  • Productivity — general workflow tools, not GTM-specific.

openai-plugin/ holds the listing metadata, icons, and MCP config for the ChatGPT and Codex plugin. Run scripts/build-openai-plugin.sh to build the ZIP you upload at platform.openai.com/plugins. Its version fields must match .claude-plugin/plugin.json, and the script fails if they don't.

See CLAUDE.md for the governance rules each bucket follows, and CONTEXT.md for the shared language used across these skills.

Reference

Blitz

Skills that wrap Blitz API directly — Waterfall ICP cascades, People Search, Company Search, enrichment, and integration recipes.

  • blitz-gtm-brainstorm — interview a GTM goal into a validated, enum-checked Blitz brief (endpoint choice, ICP filters, enrichment, volume estimate).
  • blitz-create-script — turn a GTM brief into a runnable, install-and-go Blitz SDK script with API-key safety, error handling, and pagination.
  • blitz-reviewer — review a Blitz integration before you run it: MCP installed, SDK & skills current, correct methods/bodies/enums in your code, and per-endpoint RPS/records.

GTM

General go-to-market work — lead-finding scripts, outreach, content, analytics, lifecycle automation, and the engineering that powers them.

Productivity

General workflow tools, not GTM-specific.

Contributing

When you add a skill:

  1. Put it in the right bucket (blitz/, gtm/, or productivity/).
  2. Add the skill to:
    • this README.md (under the matching section above), and
    • .claude-plugin/plugin.json (the skills array), and
    • the bucket's own README.md.
  3. Link any non-obvious design decisions in docs/adr/.
  4. If you deliberately rejected a feature request, document it in .out-of-scope/.
