Keyward is the secure-by-default platform for building and running MCP servers. Every tool call gets a scoped, short-lived credential, a per-agent identity, and a full audit trail — automatically. Ship your first secure server in under five minutes.
Built for the way agents work today
// the problem
Builders wire agents to tools with raw API keys in plaintext files. No expiry, no scope, no idea which agent did what. It's the exact problem the rest of software solved a decade ago — reborn, at machine scale.
built-in provider catalogs with route-level scopes — Stripe, OpenAI, GitHub, Notion, and more — plus custom APIs and native AWS STS.
of brokered calls audited — allow and deny both, tied to the agent that acted and the human who authorized it.
from signup to your first brokered call. Keys leave your .env for good — and every agent stays scoped, expiring, revocable.
// the product
Not a gateway you bolt on after an incident. The place you build your MCP server — where least privilege is the default, not a project.
One line of SDK swaps a static key for a scoped, short-lived credential minted at call time. Delete your .env for good.
Every agent gets its own identity. Every action ties back to the agent and the user who authorized it. Revoke one without breaking the rest.
An append-only log of every tool call: who, on whose behalf, what scope, allowed or denied. Compliance-ready, and your own peace of mind.
keyward init scaffolds a brokered agent. keyward wrap adopts your existing MCP server with zero rewrite.
Grant exactly the access a task needs, no more. 14 built-in provider catalogs with route-level scopes — plus native short-lived AWS credentials via STS, with more native providers on the roadmap.
Open-source SDK and CLI. Works with the frameworks you already use. No lock-in, no rewrite, auditable client.
// how it works
npx @keyward.dev/cli init and connect a project. Add your upstream secrets once — Keyward vaults them with envelope encryption + KMS.
Replace direct provider calls with kw.gateway(...). Same request, but the key stays in Keyward — scoped, audited, revocable.
Every call streams to your audit log and dashboard. See, scope, and revoke any agent in one click.
// pricing
The whole "aha" is free — one developer can ship one genuinely-secure server end to end. You only pay when you add a team, environments, and compliance.
For solo devs, labs, and side projects.
For startups running agents in production.
For security & platform organizations.
Join the builders shipping MCP servers that are secure from the first line of code.
