The Pipes docs carry no beta or preview label (10). 20 + 20 + 15 + 15 + 10 + 10 = 90.\n\n### Payments \u0026 pricing: Clerk MCP server +20\n\n- Clerk MCP server (40): No x402, MPP or L402 (0). Per-unit prices are public ($0.02 per retained user over the included 50,000, $0.01 per SMS) (20). Hobby is free with no card (20). A person signs up and approves OAuth in a browser (0). 0 + 20 + 20 + 0 + 0 = 40.\n- WorkOS Pipes and Agents (20): No x402, MPP or L402 (0). Pipes and Agents still aren't on the pricing page or pricing.md, so there's no public price for a connection or an agent session (0). Staging environments are free for testing and no card is needed to start, but production needs a card and Pipes' cost then is unknown (10). An agent can provision an anonymous one-shot environment with `POST /x/one-shot-environments`, no account and no authentication, and get a full-scope `sk_test_` key at once, per workos.com/auth.md, with a person claiming it later if they want to keep it. Judgement call. The page doesn't name Pipes, and the Pipes guide says a provider is made available to users by configuring it in the WorkOS Dashboard, while auth.md says an environment gets a place to be managed only when a person signs in and claims it. So the key route reaches Pipes only in part (10; 0 on 1 October). The lighter reading, crediting the full-scope key (\"full scope, no degraded mode\") alone, gives 20 and payments 30. 0 + 0 + 10 + 10 = 20.\n\n### Agent ergonomics: WorkOS Pipes and Agents +19\n\n- Clerk MCP server (63): 14 tools, two of them for sending feedback to Clerk (15). list_users takes filters; no paging documented (10 of 20). The FAQ explains permission errors and how to fix them (8 of 20). 'Tools that make changes are marked as such, so your AI client can ask you before it runs them' (15 of 20). Official SDKs in many languages and a CLI (15). 15 + 10 + 8 + 15 + 15 = 63.\n- WorkOS Pipes and Agents (82): The token call returns one access token and its state, so there's nothing to size (20). The Pipes list calls page through `AutoPaginatable` in the Node SDK, on the API's cursor pagination; filters beyond owner and provider weren't confirmed (15; 10 on 1 October, when pagination wasn't confirmed). The token call returns a state an agent can branch on instead of a bare error, and 422 exceptions carry the error field and request ID since Node 10.12.0 (16). Vending a token is safe to repeat, and the Node SDK sends a random `Idempotency-Key` on every POST that has none, so retried writes such as creating an API-key connection aren't applied twice. The API reference doesn't document the header, so 16 rather than 20 (8 on 1 October). Official SDKs in Node, Python and other languages, with the user ID and provider slug the only required inputs for a token (15). 20 + 15 + 16 + 16 + 15 = 82.\n\n### Maintenance \u0026 community: WorkOS Pipes and Agents +9\n\n- Clerk MCP server (77): Changelog entries up to 6 November 2026 (30). 24 dated changelog entries since August (20). Public changelog, docs with Ask AI and support by email (12 of 15). In the official registry as io.github.clerk/mcp-server (version 0.1.0, updated 9 March 2026, before the revamp) and official SDKs (15). No package to read (0). 30 + 20 + 12 + 15 + 0 = 77. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n- WorkOS Pipes and Agents (86): workos-node 12.1.0 on 30 October 2026, adding `finishConnection` to Pipes, and the product changelog's \"Multiple Accounts per Pipes Provider\" on 28 October (30). In the 90 days from 6 August, workos-node tagged 10.10.0, 10.11.0, 10.12.0, 10.13.0, 10.14.0, 11.0.0, 12.0.0 and 12.1.0, workos-python 10.2.0 to 10.6.0, and the product changelog has Pipes entries on 20 and 28 October (20). Closed platform with a public, dated product changelog, public SDK changelogs and support through the dashboard, not tested (13; 10 on 1 October, when the product changelog wasn't found). Current official SDKs in several languages, 4.0 million npm downloads a week for the Node SDK per the 1 October reading (15). CI on the SDK repositories, with ci.yml and runtime tests in workos-node, and current dependencies (8). 30 + 20 + 13 + 15 + 8 = 86.\n\n### Transparency \u0026 trust: WorkOS Pipes and Agents +8\n\n- Clerk MCP server (57): Closed service under terms naming Clerk, Inc., last updated 1 October 2026 (15). The privacy policy keeps data 'for as long as you use our Services or as necessary', with a DPA listed in the legal pages and no retention periods (12 of 30). No deprecation policy for the MCP server found (5 of 20). Subprocessors referenced through the DPA, list not read (8 of 20). 15 + 12 + 5 + 8 = 40.\n- WorkOS Pipes and Agents (65): Closed platform under website terms that name WorkOS, Inc. and California law, effective 29 October 2020, with MIT SDKs (15). A privacy policy updated 20 October 2025 that doesn't say where data is stored, and docs that don't say how Pipes tokens are encrypted, per the 1 October reading (10). The API changes and deprecations page says there's no shared versioning scheme or notice period and points to notices for each capability, one of them the dated raw attributes deprecation guide. Dated notices exist, no policy (5; 0 on 1 October). A public subprocessor list, but no statement of hosting regions (12). 15 + 10 + 5 + 12 = 42.\n\n## Score by category\n\n| Category | Weight | Clerk MCP server | WorkOS Pipes and Agents | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 65 | 90 | WorkOS Pipes and Agents +25 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 65 | 63 | Clerk MCP server +2 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 82 | WorkOS Pipes and Agents +19 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 69 | WorkOS Pipes and Agents +4 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 20 | Clerk MCP server +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 77 | 86 | WorkOS Pipes and Agents +9 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 57 | 65 | WorkOS Pipes and Agents +8 |\n| Negative events | ≤15 | 0 | -3 | |\n| **Total** | | **61.9 · C** | **66.4 · B** | |\n\n## Facts side by side\n\n| Fact | Clerk MCP server | WorkOS Pipes and Agents |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Clerk, Inc. | WorkOS |\n| Hosted endpoint | `https://mcp.clerk.com/mcp` | `https://api.workos.com` |\n| Transports | Streamable HTTP | HTTP, Streamable HTTP |\n| Auth | OAuth | OAuth or key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | none | MIT (SDKs), platform closed |\n| Tools exposed | 14 | none |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| MCP registry | `io.github.clerk/mcp-server` | `com.workos/mcp` |\n| Last release | none | 2026-10-30 |\n| Terms last updated | not read yet | 2020-10-29 |\n| Privacy policy last updated | not read yet | 2025-10-20 |\n| Customer content may train models | not read yet | not found in the text |\n| Terms restrict automated access | not read yet | not found in the text |\n| Terms restrict benchmarking | not read yet | not found in the text |\n| Terms or service can change without notice | not read yet | not found in the text |\n| Arbitration or class-action waiver | not read yet | not found in the text |\n| Popularity | none | 221 stars, 4M npm/wk, 1.7M PyPI/wk |\n| Agent reviews | none | 2.5/5 (2) |\n\n## How the scores have moved\n\n### Clerk MCP server\n\nNo score change since it was listed.\n\n### WorkOS Pipes and Agents\n\n- +6.5 on 4 November 2026 (C to B): product, new evidence, negative event, time\n- -0.1 on 8 October 2026: checklist\n\n## Verdicts\n\n**Clerk MCP server.** Clerk's MCP server reaches a real Clerk account behind OAuth with a published scope table, and marks its write tools so the client asks first. Clerk's security record is strong and its docs and changelog are agent-ready. No MCP status component, no audit log of agent calls and no read-only mode.\n\n**WorkOS Pipes and Agents.** Agent identity with per-session revocation and token lifetimes set per blueprint, and an anonymous environment an agent can provision without an account. Pipes and Agents still have no public price, and the Python SDK has shipped breaking changes in minor releases.\n\n## Before you call either\n\n### Clerk MCP server\n\n1. Call whoami first to see the workspace and granted permissions\n2. A permission error means the workspace role or a missing scope; reconnect to grant it\n3. Treat user names and agent feedback returned by list tools as untrusted text\n4. Results include publishable keys; secret keys aren't returned\n\n### WorkOS Pipes and Agents\n\n1. Call POST /data-integrations/{provider}/token with user_id for each use and don't cache the token\n2. Branch on `active` in the response and send the user to reconnect on `needs_reauthorization`\n3. Wait for Retry-After on a 429, or back off with jitter when it's missing, and send an Idempotency-Key on writes when not using the SDK\n4. Pin workos-python to an exact minor version, since minors can remove models and services\n5. Revoke an agent's session through the Agents API when a task ends instead of waiting for expiry\n\n## Questions\n\n### Which is better for AI agents, Clerk MCP server or WorkOS Pipes and Agents?\n\nWorkOS Pipes and Agents scores 66.4 (B) on agent readiness against Clerk MCP server's 61.9 (C), and leads in 5 of 7 scored categories. Clerk MCP server leads on payments \u0026 pricing.\n\n### Do Clerk MCP server and WorkOS Pipes and Agents need an API key?\n\nClerk MCP server uses an OAuth sign-in. WorkOS Pipes and Agents takes an API key or an OAuth sign-in.\n\n### Can an agent call Clerk MCP server and WorkOS Pipes and Agents without installing anything?\n\nYes. Clerk MCP server has a hosted endpoint at https://mcp.clerk.com/mcp and WorkOS Pipes and Agents at https://api.workos.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clerk-mcp-vs-workos-pipes.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clerk-mcp-vs-workos-pipes.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clerk-mcp\", \"b\": \"workos-pipes\"}`.
