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- 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).\n\n### Schema \u0026 documentation: Scalekit AgentKit +22\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- Scalekit AgentKit (87): OpenAPI 3.1.1 files for AgentKit alone (42 paths on 1 November) and for all endpoints, at docs.scalekit.com/api/agentkit.scalar.json (25). llms.txt with full and small variants, and a Markdown twin for each page (10). Connector pages and the API reference say what each endpoint and connector type is for (15). Filters are typed and constraints stated, for example a search query of at least 3 characters, top_k up to 50 and MCP session tokens from 60 seconds to 24 hours (13). Status codes 400, 401, 403, 404, 409 and 500 are documented, but many response examples are null placeholders (9).

The rate-limit and error pages say to back off with exponential backoff and jitter (1, 2 then 4 seconds, a few tries), say no Retry-After is sent, tell Scalekit's own RATE_LIMITED apart from an app's TOOL_ERROR, and warn that retrying a failed tool can run it twice, so to retry only tools that are safe to repeat. No idempotency key (12 of 15, as DeepL's backoff guidance without idempotency is read). Enterprise lists a 99.99 per cent uptime SLA on the pricing page (10). No beta labels on the AgentKit endpoints (10). 20+20+0+12+10+10 = 72.\n\n## Score by category\n\n| Category | Weight | Clerk MCP server | Scalekit AgentKit | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 65 | 72 | Scalekit AgentKit +7 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 65 | 87 | Scalekit AgentKit +22 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 88 | Scalekit AgentKit +25 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 66 | Scalekit AgentKit +1 |\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 | 80 | Scalekit AgentKit +3 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 57 | 66 | Scalekit AgentKit +9 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **61.9 · C** | **72.2 · BB** | |\n\n## Facts side by side\n\n| Fact | Clerk MCP server | Scalekit AgentKit |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Clerk, Inc. | Scalekit |\n| Hosted endpoint | `https://mcp.clerk.com/mcp` | `https://{env}.scalekit.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, self-hosted on Enterprise |\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 | 2026-10-30 |\n| Terms last updated | not read yet | 2026-01-01 |\n| Privacy policy last updated | not read yet | 2026-01-01 |\n| Customer content may train models | not read yet | not found in the text |\n| Terms restrict automated access | not read yet | yes |\n| Terms restrict benchmarking | not read yet | yes |\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 | yes |\n| Popularity | none | 6 stars, 11k npm/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### Scalekit AgentKit\n\n- +0.2 on 1 November 2026: reliability, product\n- +0.1 on 27 October 2026: checklist\n- -0.2 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**Scalekit AgentKit.** 600+ connectors, including remote MCP servers over OAuth 2.1 with DCR, and a free tier of 10,000 tool calls a month without a card. Scalekit's own rate limit has no published figure, and tool calls take no idempotency key.\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### Scalekit AgentKit\n\n1. Use the exact dashboard Connection Name, not the connector slug, in every call\n2. Call `POST /api/v1/tools:search` with top_k instead of listing every tool\n3. When a connected account isn't ACTIVE, send the user the magic link and stop until they finish\n4. On a 429, read error_code (RATE_LIMITED is Scalekit, TOOL_ERROR is the app), back off 1, 2 then 4 seconds, and log the executionId\n5. Mint a fresh virtual MCP session token per user per run and let it expire\n6. Retry a failed tool call only when the tool is safe to repeat, since a retry can run it twice\n\n## Questions\n\n### Which is better for AI agents, Clerk MCP server or Scalekit AgentKit?\n\nScalekit AgentKit scores 72.2 (BB) on agent readiness against Clerk MCP server's 61.9 (C), and leads in 6 of 7 scored categories.\n\n### Do Clerk MCP server and Scalekit AgentKit need an API key?\n\nClerk MCP server uses an OAuth sign-in. Scalekit AgentKit takes an API key or an OAuth sign-in.\n\n### Can an agent call Clerk MCP server and Scalekit AgentKit without installing anything?\n\nYes. Clerk MCP server has a hosted endpoint at https://mcp.clerk.com/mcp and Scalekit AgentKit at https://{env}.scalekit.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clerk-mcp-vs-scalekit-agentkit.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clerk-mcp-vs-scalekit-agentkit.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clerk-mcp\", \"b\": \"scalekit-agentkit\"}`.
