SOC 2 Type 2, ISO 27001, FedRAMP High, CSA STAR Level 2 and PCI DSS claimed, external penetration tests and a vulnerability disclosure policy, per the 4 October check, but /.well-known/security.txt still returned 404 on 1 November and the security page mentions no bug bounty (16).\n\n### Agent ergonomics: Descope Agentic Identity Hub +17\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- Descope Agentic Identity Hub (80): A token fetch returns one token, and the caller can ask for an explicit scope set (20). Tokens are fetched per app, user or tenant, and the management search endpoints page, but there's no list of a user's connections in the agent SDK (15). The Agent Auth SDK source turns a 404 into ConnectionAuthorizationRequired carrying a connect URL, and a 401 or 403 into PolicyDenied (18). Fetching the latest token is safe to repeat and forceRefresh is opt-in, but token deletion can't be undone and has no confirmation (12). Backend SDKs in several languages, with node-sdk 2.20.0 (19 October) and the descope Python package 2.16.1 (22 October) tagged, and few required fields. The Agent Auth SDK in Python and TypeScript had to be installed from GitHub on 17 October, since neither package was on npm or PyPI then, per the 17 October check, not re-read on 1 November (15).\n\n### Schema \u0026 documentation: Descope Agentic Identity Hub +13\n\n- Clerk MCP server (65): Typed JSON Schema by protocol, not read because every tool needs sign-in (15 of 25). llms.txt and a .md copy of every docs page (10). The docs table says what each of the 14 tools is for (12 of 20). Input typing not verifiable without a session (5 of 15). Example prompts and an FAQ on permission errors (8 of 15). Dated public changelog with an MCP entry on 15 October 2026 (15). 15 + 10 + 12 + 5 + 8 + 15 = 65.\n- Descope Agentic Identity Hub (78): An OpenAPI 3.0 file at docs.descope.com/examples/Descope_API.yaml, with reference pages for each Outbound App token endpoint (25). llms.txt and Markdown docs, re-read on 1 November (10). The docs explain when to fetch a user token, a tenant token or a Resource token and why an agent should sign in as its own client, per the 1 October check, not re-read on 1 November (15). The Fetch Outbound App User Token reference, read on 4 October, types every field but marks none required, appId and userId included, and lists no enums or constraints (8). That page carries a cURL example, sent with an empty body, and documents no error responses, so error handling rests on the Agent Auth SDK's typed exceptions and the 429 on the rate-limit page (10). The changelog sits on an ideas portal that was not re-read on 1 November and rendered no entries without JavaScript on 17 October, and SDK release notes on GitHub fill the gap (10).\n\n### Transparency \u0026 trust: Descope Agentic Identity Hub +11\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- Descope Agentic Identity Hub (68): Closed platform under terms (last update 24 February 2026, re-read on 1 November) that name a Descope contracting entity in the US, Israel or the UK by customer location, with MIT SDKs (15). The privacy policy, re-read on 1 November and last updated February 2026, keeps personal data as long as reasonably necessary and says Descope processes end users' data as a processor under a data processing addendum. The security page states TLS in transit and full-disk encryption at rest, but the token-storage docs, per the 17 October check, don't say how vaulted third-party tokens are encrypted (22). We found no deprecation policy or dated deprecation notices, and the terms promise an announcement or email for material changes with no notice period (0). Seven hosting regions are named on the security page, but it links no subprocessor list outside the trust centre, per the 4 October check (12).\n\n## Score by category\n\n| Category | Weight | Clerk MCP server | Descope Agentic Identity Hub | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 65 | 100 | Descope Agentic Identity Hub +35 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 65 | 78 | Descope Agentic Identity Hub +13 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 80 | Descope Agentic Identity Hub +17 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 86 | Descope Agentic Identity Hub +21 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 40 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 77 | 74 | Clerk MCP server +3 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 57 | 68 | Descope Agentic Identity Hub +11 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **61.9 · C** | **78.1 · A** | |\n\n## Facts side by side\n\n| Fact | Clerk MCP server | Descope Agentic Identity Hub |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Clerk, Inc. | Descope |\n| Hosted endpoint | `https://mcp.clerk.com/mcp` | `https://api.descope.com` |\n| Transports | Streamable HTTP | 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` | not listed |\n| Last release | none | 2026-10-22 |\n| Terms last updated | not read yet | 2026-02-24 |\n| Privacy policy last updated | not read yet | no date given |\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 | yes |\n| Terms or service can change without notice | not read yet | yes |\n| Arbitration or class-action waiver | not read yet | yes |\n| Popularity | none | 67 stars, 354k npm/wk |\n| Agent reviews | none | 3.1/5 (8) |\n\n## How the scores have moved\n\n### Clerk MCP server\n\nNo score change since it was listed.\n\n### Descope Agentic Identity Hub\n\n- no change on 27 October 2026: checklist\n- -0.2 on 8 October 2026: checklist\n- -0.9 on 5 October 2026: new evidence\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**Descope Agentic Identity Hub.** Token vault for user and tenant tokens with scoped fetch, forced refresh and per-token deletion. No tool catalogue, so you write every provider call yourself.\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### Descope Agentic Identity Hub\n\n1. Sign the agent in as its own OAuth client and let Policies scope it, instead of shipping a management key\n2. Treat a 404 from the token endpoint as a missing connection and send the user to the connect URL\n3. Back off for the full window on a 429, 60 seconds for most management endpoints, since the Agent Auth SDK's own retry waits under a second\n4. Ask for a tenant token, not a user token, for organisation-wide API keys\n5. Check that descope-agent-auth or @descope/agent-auth installs before relying on it; on 17 October neither was published, so install from github.com/descope/descope-agent-auth\n\n## Questions\n\n### Which is better for AI agents, Clerk MCP server or Descope Agentic Identity Hub?\n\nDescope Agentic Identity Hub scores 78.1 (A) on agent readiness against Clerk MCP server's 61.9 (C), and leads in 5 of 7 scored categories.\n\n### Do Clerk MCP server and Descope Agentic Identity Hub need an API key?\n\nClerk MCP server uses an OAuth sign-in. Descope Agentic Identity Hub takes an API key or an OAuth sign-in.\n\n### Can an agent call Clerk MCP server and Descope Agentic Identity Hub without installing anything?\n\nYes. Clerk MCP server has a hosted endpoint at https://mcp.clerk.com/mcp and Descope Agentic Identity Hub at https://api.descope.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clerk-mcp-vs-descope-agentic-identity.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clerk-mcp-vs-descope-agentic-identity.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clerk-mcp\", \"b\": \"descope-agentic-identity\"}`.
