Which one, for what

Cloudflare Workers OAuth Provider BB

Best for Developers putting a remote MCP server on Cloudflare behind standard OAuth.

Ahead on

  • Payments & pricing, 50 against 40
  • Maintenance & community, 87 against 81
  • Transparency & trust, 86 against 77

Also in its favour

  • Open source
  • No incidents deducted, where Vercel Connect loses 3 points for them

Watch for

Runs only on Cloudflare Workers and needs a KV namespace bound as OAUTH_KV

Vercel Connect BB

Best for Teams already deploying on Vercel whose agents need user or app tokens for Slack, GitHub, Microsoft, Linear, Snowflake or an MCP server without storing provider secrets, and providers behind IP allowlists through Secure Compute.

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

Vercel's SLA says it does not apply to the APIs or CLI, so token requests carry no uptime commitment

Payments & pricing Cloudflare Workers OAuth Provider +10

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.

Vercel Connect 40

No x402, MPP or L402 (0). Unit prices are public without a login, re-read on 1 November 2026, $3.00 per 1,000 token requests and $0.95 per 1,000 triggers on Pro, and MCP Events deliveries are billed as triggers (20). Hobby includes 500 token requests and 1,000 triggers a month at no charge, for non-commercial use. The Hobby plan page, read on 17 October, calls the plan free with no billing cycles and asks for card details only when upgrading to Pro (20). A person signs up in a browser, and connectors and user consent also pass through a browser (0).

Transparency & trust Cloudflare Workers OAuth Provider +9

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.

Vercel Connect 77

Closed service under the Terms of Service last updated 19 October 2026, with the Connect product terms now in Vercel's Service Terms (last updated 15 October 2026), and an Apache-2.0 SDK and CLI (20). A privacy notice (last updated 1 June 2026) and a DPA exist. The DPA, read on 17 October, is effective 31 March 2026, covers Pro and Enterprise only and has customer data deleted within a commercially reasonable time after termination. The docs say refresh tokens are stored on Vercel's infrastructure and give event retention by plan. We found no retention period or encryption statement for stored provider credentials (18). No deprecation policy found. The Service Terms still let Vercel "add or remove Third Party Platforms to Vercel Connect without notice", though the beta price change was announced with a date of 25 September 2026 (5). The DPA points to a subprocessor list on security.vercel.com and says primary processing is in the United States. We saw the list's page but could not read its entries (12).

Maintenance & community Cloudflare Workers OAuth Provider +6

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.

Vercel Connect 81

@vercel/connect 2.7.0 was published on 31 October 2026, per npm's search API (30). The Vercel changelog has Connect entries on 11 and 25 August, 11, 21, 24 and 29 September, three on 15 October, and on 23, 26 and 29 October 2026 (managed Stripe API keys, service discovery in the CLI, webhook triggers for five more providers) (20). Closed service with a dated public changelog. The public copy of the SDK in vercel/vercel was synced from Vercel's internal repository on 27 October at 2.5.6, behind npm, and we didn't read issue replies (10). One current official SDK (15). One runtime dependency (@vercel/oidc 4.0.5 at 2.7.0) and a test folder in the package. We didn't confirm CI status on the default branch (6).

How the scores have moved

Verdicts

Cloudflare Workers OAuth Provider

Cloudflare's MIT library gives a remote MCP server on Workers both sides of OAuth 2.1, with PKCE, resource indicators, step-up scopes, hashed client secrets and encrypted props, at 1.2.4 with a conformance suite. It runs only on Workers with KV, 1.2.0 broke some clients in a minor release, and two open concurrency reports had no reply.

Vercel Connect

Provider refresh tokens stay with Vercel, and code receives short-lived tokens tied to a project and environment through one call with a public OpenAPI definition. Vercel's SLA excludes its APIs, Connect had elevated errors for some customers on 10 and 18 September 2026, and the only SDK is TypeScript.

Before you call either

Cloudflare Workers OAuth Provider

  1. Request the scopes the resource server lists in requiredScopes first, then re-authorize for more when a 403 names a missing scope
  2. Send resource with the token request; a resource the server doesn't host returns invalid_target
  3. Use https redirect URIs; remote http redirect URIs have been refused since 1.2.0
  4. Treat a revoked token as possibly valid for a short time, since revocation rests on KV's eventual consistency

Vercel Connect

  1. Call getToken at request time and don't store the result. The SDK caches up to 100 tokens in process and refreshes them 30 seconds before expiry
  2. Pass scopes on every request. Since SDK 1.0.0 an omitted scopes defaults to ['*'], the connector's default scopes
  3. Catch UserAuthorizationRequiredError, call startAuthorization and send the user to the returned URL. Consent needs a person in a browser
  4. Outside Vercel, pass a Vercel access token as vercelToken. It can request only the app subject or its own user, not another user
  5. On a 429 wait one minute for the window to reset. Limits are 200 token requests a minute per team
