The universal context engine connecting agents to data, tools, and models
One normalized API connects your product to hundreds of HRIS, payroll, ATS, CRM, accounting, ticketing, and file storage systems with read and write access.
Give agents secure, authenticated access to thousands of pre-built tools across third-party services, with scoped permissions and audit logs.
Route every model through one API with automatic failover, pre-built or custom routing rules, and spend and performance controls.
Distribute approved MCP connectors, models, and skills to employee AI tools with per-team budgets, DLP scanning, and audit logging.
Design, test, and govern APIs — now with AI agents in the loop
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.
