About nab

nab is an MCP server published by the GitHub account MikkoParkkola. Token-optimized HTTP client for LLMs: fetches any URL as clean markdown. CLI and MCP server.

It runs on your own machine: your AI client starts it from the cargo package nab at version 0.12.6.

It asks for no keys or passwords.

Version 0.12.6 was published on 24 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 3 pass, 1 warn, 0 fail, 3 info. How we check.

What it asks for

Variable	Required	Secret	Description
`NAB_SSRF_ALLOW_PRIVATE`	No	No	Set to allow fetching private/internal IP addresses (corporate dashboards). Never unblocks loopback, link-local/cloud-metadata, or other always-denied ranges. Off by default.
`NAB_SSRF_ALLOWLIST`	No	No	Comma-separated list of private IP/CIDR ranges to exempt from the SSRF guard (e.g. 10.252.0.0/16,192.168.1.5). Narrower, preferred alternative to NAB_SSRF_ALLOW_PRIVATE. Empty by default.
`NAB_WEBMCP_STRICT`	No	No	Set to a truthy value to require fetched pages advertising a WebMCP manifest to match NAB_WEBMCP_OPT_IN before ingestion is allowed (defense against prompt injection via fetched content). Off by default.
`NAB_WEBMCP_OPT_IN`	No	No	Comma-separated allowlist consulted when NAB_WEBMCP_STRICT is enabled. Empty by default.
`NAB_STATE_DIR`	No	No	Overrides the directory used to persist session/cookie state (default: ~/.nab).
`NAB_KEYCHAIN_INTERACTION`	No	No	Controls whether cookie extraction may prompt macOS Keychain for authorization. Set to 'never' in automated/headless callers so a background fetch cannot open a GUI dialog.
`NAB_OP_BIN`	No	No	Path to the 1Password CLI binary used for credential retrieval during the login tool (default: op).
`NAB_MCP_CLI_BIN`	No	No	Path to the mcp-cli binary used for MCP-based credential retrieval (default: mcp-cli).
`NAB_NO_TELEMETRY`	No	No	Set to anything other than 0 or false to skip the daily heartbeat. NO_TELEMETRY and DO_NOT_TRACK do the same.
`NAB_TELEMETRY_ENDPOINT`	No	No	Replace the daily heartbeat URL. An empty value leaves the default.
