What is Clerk?

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

What is Redocly?

Redocly ships a built-in MCP server page across its entire docs platform, with public and authenticated endpoints

Redocly just landed a coordinated 0.137.0 release across Reef, Realm, Revel, and Redoc, anchored by a structural addition: every developer portal now ships a `/mcp` page with setup instructions for Claude, ChatGPT/Codex, and raw JSON config, plus an opt-in `/mcp-public` endpoint for serving anonymous-accessible content without authentication. The MCP code mode got reliability improvements, OAuth discovery was fixed to spec (RFC 8414), and four CVEs were patched in the same release. The breadth of the drop — 20 features and 67+ bug fixes across packages — reflects a team that released a major capability and simultaneously cleared accumulated UX debt.

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

◆ Current state

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

◆ Where it's heading

Clerk is extending from human sign-in toward credentials for software acting on a user's behalf, and pricing that surface by the call rather than by the seat. The CLI framing makes the direction explicit: the control plane should be operable by an agent, not only by a person in a dashboard. Meanwhile SCIM, logs, and billing controls are the enterprise checklist that lets it sell upmarket while that bet plays out.

◆ Prediction

Expect the machine authentication suite to deepen around delegated and scoped access for agents — finer-grained key permissions or short-lived credentials — with usage-based pricing extended to whatever ships next.

Redocly ships a built-in MCP server page across its entire docs platform, with public and authenticated endpoints

◆ Current state

Redocly just landed a coordinated 0.137.0 release across Reef, Realm, Revel, and Redoc, anchored by a structural addition: every developer portal now ships a `/mcp` page with setup instructions for Claude, ChatGPT/Codex, and raw JSON config, plus an opt-in `/mcp-public` endpoint for serving anonymous-accessible content without authentication. The MCP code mode got reliability improvements, OAuth discovery was fixed to spec (RFC 8414), and four CVEs were patched in the same release. The breadth of the drop — 20 features and 67+ bug fixes across packages — reflects a team that released a major capability and simultaneously cleared accumulated UX debt.

◆ Where it's heading

Redocly is repositioning every hosted API portal as a first-class AI agent resource, not just a human-readable docs site. The public MCP endpoint especially matters: it enables AI coding assistants to read API docs without credentials, which removes the main friction for developers integrating via LLM tools. Security hardening (audience validation, OAuth compliance, CVE patching) in the same release signals this isn't a prototype feature — it's going into production. The next logical step is deeper programmatic authoring via the MCP surface, not just reading.

◆ Prediction

Expect Redocly to add MCP write-path features — letting AI agents update API documentation or sync specs directly — once the read-path is fully stable. The visual review check in Reunite suggests a git-workflow integration direction.
