          "2026-06-30. A public issue reports non-blind SSRF from workflow `http_request` and file download blocks to loopback, private and metadata addresses in version 1.0.39, with a reproduction (https://github.com/Skyvern-AI/skyvern/issues/6915). The issue is still open on 8 October 2026 and no advisory is published, but the 1.0.55 source routes these requests through an SSRF-guarded resolver, so we deduct 3 and not more. We didn't reproduce it, and whether Skyvern Cloud was exposed isn't stated."
        ],
        "verdict": "The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.",
        "bestFor": "Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.",
        "strengths": [
          "Every MCP tool carries readOnlyHint, destructiveHint and openWorldHint annotations, 117 registrations in the 1.0.55 source",
          "Hosted MCP scopes cut the advertised tools from 114 to 29 (`operate`) or 32 (`lean`) by URL or `X-Skyvern-Scope` header",
          "Written deprecation policy with six months' notice, 12 for a major version, and `Deprecation` and `Sunset` response headers",
          "OpenAPI 3.1.0 with 94 operations, llms.txt, Markdown twins of every docs page and a weekly dated changelog",
          "Stored passwords, cards and TOTP secrets are injected into the browser and replaced by placeholders in prompts, recordings and logs, per the docs"

        "weaknesses": [
          "Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys",
          "No request rate limits in the docs. Responses carry `ratelimit-policy: \"submit-run\";q=50;w=60`, and only plan concurrency is published",
          "What a credit buys is stated three ways (one credit an action, 5,000 credits for about 170 or about 200 actions, by run complexity)",
          "An SSRF report against 1.0.39 from 30 June 2026 is still open with no advisory, though 1.0.55 source has SSRF guards",
          "Retention is \"as long as necessary\", anonymised data may train models unless you opt out by email, and no subprocessor list was readable"

          "Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send `X-Skyvern-Scope`, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions",
          "Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows",
          "Never pass passwords to `skyvern_act` or `skyvern_type`. Store them as credentials and call `skyvern_login`",
          "Set `max_steps` on tasks, or `x-max-steps-override` on agent runs, to cap credits. A run that reaches the cap ends as `timed_out`",

The docs state there are no read-only, per-endpoint or per-resource keys\n\n\n## Score by category\n\n| Category | Weight | Functionize MCP server | Skyvern | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 50 | 57 | Skyvern +7 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 29 | 88 | Skyvern +59 |\n| Agent ergonomics | 13% (16.2 this run) | 43 | 76 | Skyvern +33 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 59 | Skyvern +3 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 32 | Skyvern +2 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 49 | 85 | Skyvern +36 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 59 | 72 | Skyvern +13 |\n| Negative events | ≤15 | 0 | -3 | |\n| **Total** | | **44.7 · E** | **63.1 · B** | |\n\n## Facts side by side\n\n| Fact | Functionize MCP server | Skyvern |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Functionize, Inc. | Ikonomos Inc.

It uses OAuth with read and write scopes and has a no-card free plan. Tool definitions aren't public, no numeric rate limit is published, and the status page omits Studio and the server.\n\n**Skyvern.** The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.\n\n## Before you call either\n\n### Functionize MCP server\n\n1. Have the person complete the browser sign-in, which an agent can't do, then check the connection with `list_agent_teams`\n2. Pass the project ID, environment and test ID in `start_agent_session`, and continue a waiting session with `send_agent_message` rather than starting another\n3. Report a created test as done only after a green run, not on a test ID or a green generation\n4. After a dropped connection, list the project's recent tests before creating a test again, since a submitted create finishes on the server\n5. Send the `X-Functionize-Team-Id` header to pin a team, and keep credentials in masked Studio variables, never in prompts\n\n### Skyvern\n\n1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send `X-Skyvern-Scope`, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions\n2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows\n3. Never pass passwords to `skyvern_act` or `skyvern_type`. Store them as credentials and call `skyvern_login`\n4. Set `max_steps` on tasks, or `x-max-steps-override` on agent runs, to cap credits. A run that reaches the cap ends as `timed_out`\n5. On 503 from POST /v1/run/agents, wait `Retry-After` seconds. No run was created, so resubmitting is safe\n\n## Questions\n\n### Which is better for AI agents, Functionize MCP server or Skyvern?\n\nSkyvern scores 63.1 (B) on agent readiness against Functionize MCP server's 44.7 (E), and leads in every scored category.\n\n### Do Functionize MCP server and Skyvern need an API key?\n\nFunctionize MCP server uses an OAuth sign-in. Skyvern takes an API key or an OAuth sign-in.\n\n### Can an agent call Functionize MCP server and Skyvern without installing anything?\n\nYes. Functionize MCP server has a hosted endpoint at https://mcp.functionize.com/mcp and Skyvern at https://api.skyvern.com/v1.\n\n### Are Functionize MCP server and Skyvern open source?\n\nNo open-source release is listed for Functionize MCP server. Skyvern is open source (AGPL-3.0 for the open-source server, SDKs and MCP server. Skyvern Cloud is a proprietary service under Skyvern's terms, and its anti-bot measures aren't in the repository).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/functionize-mcp-vs-skyvern.json, and with the fewest tokens: https://www.anchorterminal.com/compare/functionize-mcp-vs-skyvern.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"functionize-mcp\", \"b\": \"skyvern\"}`.
