🤖 AI-Native Infrastructure

Your agents talk to our API.
We handle the tokens.

From autonomous coding agents to multi-agent orchestration — every agent workflow needs one-time access tokens, session hand-offs, and revocation. OneLinkToken is built for that world.

MCP-native

Model Context Protocol

Native MCP server exposes token creation, redemption, revocation, and status as discoverable tools. Your AI agent discovers what it can do and calls it directly — no middleware, no glue code.

Agent-to-Agent

Agent Delegation Tokens

Agent A creates a one-time magic link for Agent B. Token encodes the scope: which actions, which data, how long. No shared secrets. No hardcoded credentials. Pure ephemeral delegation.

Zero Trust

Convoy of One-Time Credentials

Every token is single-use by default. Redeemed tokens vanish. Revoked tokens propagate in <100ms. Your agent pipeline never accumulates stale credentials — each step is independently authorized.

⚡ Open Standard

Connect in one line.

Our official MCP server exposes 7 tools your AI agent discovers and calls directly. No REST boilerplate. No SDK. No authentication wrappers.

01
create_magic_link → token_id, magic_link_url, expires_at
02
create_otp / create_bearer_token → token_id, raw_token, expires_at
03
redeem_token / revoke_token → valid, status, reason
04
get_token_status / list_tokens → full token state
