Secure every
MCP tool call
Model Context Protocol servers hand agents the keys to your data and actions. Authenticate every client, authorize every tool call against fine-grained policy, and revoke access the moment something looks wrong.
Capabilities
Identity-aware access for MCP
Everything you need to put authentication, authorization, and audit in front of every Model Context Protocol server you run.
Client Authentication
Every MCP client — IDE, agent, or app — proves who it is before it can list or call a tool. No anonymous connections to your servers.
Per-Tool Authorization
Allow or deny each tool call against fine-grained policy, scoped per agent, per tool, and down to the individual resource it touches.
Scoped Machine Identity
Issue short-lived, least-privilege credentials to agents and MCP servers so a leaked token can never do more than its narrow scope.
Token Vault
Broker the third-party API tokens your tools need centrally, so MCP servers never store raw secrets and access can be cut off instantly.
Drop-In Integration
Wrap any MCP server with identity-aware access without rewriting your tools — the protocol stays standard, the security comes for free.
Full Audit Trail
Every connection and tool call is recorded with the identity behind it, giving you a complete, exportable record of what each agent did.
Authorize every tool call
Identity at the protocol layer
Authdog sits between your MCP client and server. Each request carries a verified identity — human or machine — and is checked against policy before the tool runs. Scope access per agent, per tool, and per resource, and watch every decision land in your audit log.
Why MCP identity matters
MCP servers are execution surfaces: a single tool call can read sensitive data or trigger real actions. Treat them like production endpoints — authenticated, authorized, and fully audited.
Of MCP servers ship without identity enforcement
MCP adoption is outpacing governance. Most servers expose tools with no authentication at all — Authdog adds it without changing your tool code.
Of tool calls authorized at the resource level
Every invocation is checked against fine-grained policy before it runs, so an agent can only reach the tools and data you've explicitly granted.
To revoke a compromised agent's access
Kill a token or flip a policy and the next tool call is denied instantly — no redeploy, no waiting for credentials to expire.
Secure your MCP deployment.
Add client authentication, machine identity, and fine-grained authorization to every MCP server — in minutes, without rewriting your tools.
