Cloudflare Workers OAuth Provider vs Scalekit AgentKit

Cloudflare Workers OAuth Provider 86

MIT (30). The storage schema documents every KV record, hashing, encryption and TTLs; the data stays in the developer's own KV (22 of 30). The migration guide covers every change since 0.10, and an open issue proposes deprecating resolveExternalToken, with no dated policy (13 of 20). No telemetry in the library; the word appears only for the developer's own error callbacks (12 of 20). Total 77.

Scalekit AgentKit 66

Closed platform under terms that name ScaleKit, Inc. and Delaware law (effective 1 January 2026), with MIT SDKs (15). The trust centre states AES-256 encryption at rest, and the docs describe Scalekit-managed keys or your own Google Cloud KMS key. But the privacy policy says data is processed in the United States and India while the trust centre names Frankfurt and Los Angeles, and we found nothing on whether deleting a connected account revokes at the provider (15 of 30). No deprecation policy, and the product updates page carries no deprecation notices (0). Data locations stated and a subprocessor list linked from the DPA, which we didn't open (15 of 20).

Cloudflare Workers OAuth Provider 74

Framework reading. Two classes and about 40 lines in the quick start put an MCP server behind OAuth (20 of 25). Required scopes and step-up per request (16 of 20). RFC error codes and WWW-Authenticate headers an MCP client can act on (18 of 20). Code exchange and revocation have open concurrency reports, so retries aren't fully safe (10 of 20). TypeScript on Workers only, with sensible defaults (10 of 15). Total 74.

Scalekit AgentKit 88

Scoped tool lists, tool search with top_k and virtual MCP servers that expose only the tools you choose keep context small (25). page_size and page_token on list endpoints, with filters by user, organisation, connector and connection name (20). Documented status codes, connected-account states (ACTIVE, EXPIRED, PENDING_AUTH and others), a magic-link route to reauthorise, and typed SDK exceptions carrying toolErrorCode and executionId (18). No idempotency keys. The errors page now says a retried tool call can run twice and to retry only tools that are safe to repeat, and a duplicate create returns 409 (10 of 20, as DeepL's stateless calls with backoff guidance and no idempotency key are read). Official Node and Python SDKs and few required fields (15).

Cloudflare Workers OAuth Provider 80

OAuth 2.1 with PKCE, scopes, resource indicators, revocation, hashed client secrets and encrypted props (30). Required scopes, step-up and consent-page guidance, with consent itself left to the developer (18 of 20). Returns no untrusted content (10). No audit log of grants or token use built in (5 of 15). Cloudflare's HackerOne programme, security@cloudflare.com and a valid security.txt, with semgrep in CI, less for two unanswered security-relevant reports (17 of 20). Total 80.

Scalekit AgentKit 66

Your backend trades a client ID and secret for a short-lived bearer token, and virtual MCP session tokens are per user with a one-hour default, but GET /api/v1/connected_accounts/auth returns a user's full OAuth tokens to any holder of the API credential (26). Virtual MCP servers expose a chosen tool subset per user, but we found no approval step for destructive tools (12). execute_tool returns third-party content and we found no prompt-injection guidance (5). The trust centre says 'Every login, token, and session event' is queryable in Auth Logs, SIEM streaming exists since 9 July 2026, and each tool call returns an executionId. We found no AgentKit-specific audit log (8 of 15). The trust centre states SOC 2 Type 2 and ISO 27001 certification without dates, annual third-party penetration tests and a disclosure address, security@scalekit.com. /.well-known/security.txt returns 404 and we found no bug bounty (15 of 20).

Cloudflare Workers OAuth Provider 50

Self-hosted rule. No x402, MPP or L402 (0 of 40). Free under MIT, with Workers prices public (20). Workers has a free plan (20). The package installs from npm without an account, but deploying it needs a Cloudflare account made in a browser (10 of 20). Total 50.

Scalekit AgentKit 40

No x402, MPP or L402 (0). Per-call price published, $0.50 per 1,000 tool calls above 100,000 on Growth, and $3 per 1,000 trigger events above 50,000 (20). Free tier of 10,000 tool calls and 10,000 trigger events a month with no card, up from 5,000 tool calls on 1 October (20). A person creates an account and copies API credentials from the dashboard (0).

Cloudflare Workers OAuth Provider 87

1.2.4 on 22 October 2026 (30). Nine npm releases in 90 days (20). Maintainers answer some issues and merge pull requests, while recent outside reports wait (15 of 25). Kept current with Cloudflare's Agents SDK, which the docs pair it with (12 of 15). npm provenance, changesets, semgrep and conformance CI (10). Total 87.

Scalekit AgentKit 80

scalekit-sdk-node 2.21.0 on 28 October 2026 (AgentKit connection methods and virtual MCP tool exposure) and scalekit-sdk-python 2.23.0 on 30 October (AgentKit triggers) (30). 11 Node and 8 Python SDK releases in the 90 days from 3 August (20). Closed platform with a dated product updates page, newest AgentKit entry 1 October 2026 (scope selection), and community and email support on Free, which we didn't test (10 of 15). Official Node and Python SDKs are current (15). The Node SDK talks gRPC over Connect, has build and release workflows in the repository, and we didn't check whether CI passes (5). 30+20+10+15+5 = 80.
