The CLI, MCP server, and npm library that turns any website into an API — no docs, no SDK, no browser.
ApiTap is a CLI, MCP server, and npm library that lets AI agents (and you) browse the web through APIs instead of browsers. Point it at a site: it captures the internal API from real traffic, generates a portable signed skill file, and replays requests directly with fetch(). Credentials never live in the file — they stay in encrypted storage and are injected at replay — and replays are matched against the captured route shapes, so your agent learns an endpoint drifted before it fails mid-task. No DOM, no selectors, no flaky waits. Token costs drop 20-100x compared to browser automation. Sites that publish OpenAPI specs can skip capture entirely via apitap import (APIs.guru directory built in).
The web was built for human eyes; ApiTap makes it native to machines.
# Capture a site's private API once... apitap capture https://polymarket.com # ...then replay it forever — no browser in this path apitap replay gamma-api.polymarket.com get-events # Read page content without a browser apitap read https://en.wikipedia.org/wiki/Node.js ✓ Wikipedia decoder: ~127 tokens (vs ~4,900 raw HTML) # Or import published OpenAPI specs directly apitap import --from apis-guru --search stripe apitap replay api.stripe.com get-listcharges limit=5
No scraping. No browser. Just the API.
How It Works
ApiTap has three ways to build its API knowledge:
- Capture (30 seconds) — Launch a browser, visit a site, browse normally. ApiTap intercepts all network traffic v

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions
What is the ApiTap MCP server?
CLI, MCP server, and npm library that turns any website into an API — no docs, no SDK, no browser.
What tools does ApiTap expose?
14 in total: 13 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is ApiTap safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (33/100) and found 7 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does ApiTap need?
It reads APITAP_ALLOW_LEGACY_KEYS and GITHUB_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does ApiTap run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @apitap/core at 2.3.0.
How current is this page?
The grade is for one exact copy of the source (d36e98153c94), read on 2026-10-07. The repository is watched and re-audited when it changes.
