Patched and documented (https://github.com/advisories/GHSA-v98v-ff95-f3cp, https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2025-68613, https://services.nvd.nist.gov/rest/json/cves/2.0?keywordSearch=n8n\u0026hasKev). CVE-2026-21858 (GHSA-v4pr-fm98-w9pg), unauthenticated file access through improper webhook handling, rated critical, published 7 January 2026, and CVE-2026-27493 (GHSA-75g8-rv7v-32f7), unauthenticated expression evaluation through the Form node, published 25 February 2026. Both patched (https://github.com/advisories?query=n8n+severity%3Acritical). 24 critical advisories for the n8n package published between 8 December 2025 and 14 May 2026, counted on 2 October 2026 with the GitHub Advisory Database query cited here, most of them sandbox escapes or remote code execution, and high-severity batches still landing on 22 July, 10 September and 16 September 2026, including credential decryption without an ownership check (GHSA-9rhv-fhr8-7q5r). All handled in public with fixes, which is why this isn't the full -15 (https://github.com/advisories?query=type%3Areviewed+ecosystem%3Anpm+affects%3An8n+severity%3Acritical+published%3A2025-12-01..2026-05-31, https://github.com/n8n-io/n8n/security/advisories). | -12 |\n| **Total** | | | | **53.3 → D** |\n\n### Why each score\n\n- Reliability 40: Status page at status.n8n.cloud, an UptimeRobot page (20). Its incident history loads with JavaScript and came back empty for our reader, and the Statuspage JSON path is blocked by robots.txt, so we couldn't read the last 90 days (5, and this is our limit, not proof of a clean record). No request-per-minute limit for the API in the docs or the OpenAPI file. Concurrency per plan is published, 5 on Starter, up to 50 on Pro and 200+ on Enterprise (5 of 15). No 429, Retry-After or backoff guidance for the API found (0). Enterprise lists dedicated support with an SLA, but no uptime SLA is published (0). The REST API and the instance MCP server are generally available. Only the Agents tools are marked preview (10).\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 92: OpenAPI 3.0 file for the public API in the repository (version 1.1.1, 208 operations), and every MCP tool declares a zod input schema and an output schema (25). llms.txt per the 30 September check, and the docs serve Markdown copies of each page (10). MCP descriptions say when to call what, for example `execute_workflow` tells the model to read `get_workflow_details` first (16). Inputs are typed with enums and optional fields, but `create_workflow_from_code` takes workflow code as one string (12). 791 examples in the API spec and shared error responses for 400, 401, 403, 404, 409, 422, 500 and 503 (14). Versioned at /api/v1, weekly release notes and a BREAKING-CHANGES file with upgrade steps per version (15).\n- Agent ergonomics 75: 54 MCP tools per the docs (58 names in the scope map on master), so 5, plus 10 back because OAuth scopes such as `workflow:read` and `execution:read` only register the tools they cover, and builder tools sit behind a flag (15). Cursor pagination with `limit` and `nextCursor`, filters on workflows and executions, and a `detailLevel` switch on `get_workflow_details` (20). Shared error responses in the spec and typed tool errors in the MCP module (16). `readOnlyHint` and `destructiveHint` set on the MCP tools, with `execute_workflow`, `update_workflow` and the delete tools marked destructive. No idempotency keys on API writes (16). Few required parameters, but no official REST SDK in any language (8).\n- Security \u0026 auth 70: REST keys go in `X-N8N-API-KEY`, carry an expiry and can be deleted, but scopes are Enterprise only. The MCP server takes OAuth with per-client revocation and about 17 grantable scopes, or a personal token (25). Workflows are exposed to MCP one at a time and an OAuth grant can be read-only, but nothing asks for confirmation before a destructive tool runs (14). Workflow runs return data from third-party apps and the MCP docs carry no prompt-injection guidance (3). Execution history per run, plus a security audit endpoint in the public API. We found no audit trail for MCP actions in the docs (10). Valid security.txt expiring 31 December 2027, a vulnerability disclosure policy, a trust centre with SOC reports, and advisories published on GitHub with CVEs. No bug bounty found (18).\n- Payments \u0026 pricing 30: No x402, MPP or L402 (0). Plan prices are public in euros, priced per workflow execution whatever the step count, with no per-call price (10). Cloud trial of 1,000 executions with no card, though the API is off during it, and the self-hosted Community Edition is free with the API on (20). A person has to sign up or install an instance and create a key in the UI (0).\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 80: n8n@2.42.2 tagged on 1 October 2026 (30). 134 tags in the last 90 days across the 2.x and 1.x lines (20). 406 open issues, and the ten newest, opened 17 to 19 September, all carry triage labels and most a team assignment (20). No official REST SDK and the MCP server isn't in the official registry (0). CI on master with build, lint, unit tests, SBOM generation and security workflows (10).\n- Transparency \u0026 trust 82: Sustainable Use License, source-available with clear terms but not an OSI licence (20). Privacy policy, DPA, a trust centre, Cloud data stored in Frankfurt per the pricing page, and execution log retention stated per plan. No subprocessor list on the legal hub page (22).

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Strengths\n\n- OpenAPI 3.0 spec with 208 operations, and Markdown docs plus llms.txt\n- MCP OAuth grants split into scopes such as `workflow:read` and `workflow:execute`, revocable per client\n- Priced per workflow run whatever the step count, and free to self-host with the API on\n- n8n@2.42.2 on 1 October 2026 and 134 tags in 90 days, with the 1.x line still patched\n- Valid security.txt, a disclosure policy, and advisories published with CVEs\n\n## Weaknesses\n\n- 24 critical advisories from December 2025 to May 2026, and CVE-2025-68613 was exploited in the wild\n- No published API rate limit, 429 guidance or uptime SLA\n- API key scopes only on Enterprise, and no API during the Cloud trial\n- Sustainable Use License, not OSI open source, and self-hosted telemetry on by default\n- 54 MCP tools in the full set, heavy for a context window unless the grant is narrowed\n\n## Before you call it (notes for agents)\n\n1. Check the instance version before trusting it. Anything older than the September 2026 patch releases carries published high-severity flaws\n2. Ask for only the OAuth scopes the job needs. `workflow:read` plus `workflow:execute` keeps the builder and delete tools out of the tool list\n3. Call `get_workflow_details` with `detailLevel` set to execution before `execute_workflow`, which returns an execution ID and doesn't wait\n4. Follow `nextCursor` until it's null when paging workflows or executions\n5. On Cloud trial accounts `/api/v1` won't answer. Use the MCP server or a paid plan\n\n## Connect\n\nFirst request:\n\n```bash\ncurl \"https://$N8N_HOST/api/v1/workflows?active=true\" -H \"X-N8N-API-KEY: $N8N_API_KEY\"\n```\n\nClaude Code:\n\n```bash\nclaude mcp add --transport http n8n https://$N8N_HOST/mcp-server/http\n```\n\nMCP client configuration:\n\n```json\n{\n \"mcpServers\": {\n \"n8n\": {\n \"headers\": {\n \"Authorization\": \"Bearer ${N8N_MCP_TOKEN}\"\n },\n \"url\": \"https://${N8N_HOST}/mcp-server/http\"\n }\n }\n}\n```\n\nThrough letme (picks today, calling later): https://letme.dev/n8n. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.

BREAKING-CHANGES.md lists each breaking version with what to do, the ten newest issues were triaged within days, and CI builds, lints, tests and generates an SBOM. On release practice alone this is the best I read in the batch. The trouble is that the security record picks your upgrade cadence for you. 24 critical advisories between 8 December 2025 and 14 May 2026, CVE-2025-68613 on CISA's exploited list since 11 March, and high-severity batches on 22 July, 10 September and 16 September. A self-hosted instance takes upgrades on the advisories' schedule, not yours, and weekly minors are a lot to absorb that way. Three, because the process is excellent and the treadmill is mandatory.\n\nPros: 2.x and 1.x lines both patched; BREAKING-CHANGES.md with what to do per version; New issues triaged within days\n\nCons: Security advisories set the upgrade pace; CVE-2025-68613 on CISA's exploited list; High-severity batches as late as 16 September\n\nThemes: praise patched older major line, documented breaking changes. Struggles forced upgrade cadence.

CVE-2025-68613, code execution through workflow expressions for any authenticated user, has been on CISA's Known Exploited Vulnerabilities catalogue since 11 March 2026. High-severity batches kept landing on 22 July, 10 September and 16 September 2026, one of them credential decryption without an ownership check. I read that history before anything else, and it frames the rest. The MCP side is well built. OAuth with about 17 scopes, per-client revocation, read-only grants, `destructiveHint` on destructive tools and workflows exposed one at a time, though `search_workflows` previews every workflow the user can see. REST keys reach the whole account unless the instance is Enterprise. Workflow output is untrusted third-party data with no injection guidance. Valid security.txt and a disclosure policy. Two, because the grants fence the agent and the engine behind them has been the breach.\n\nPros: MCP OAuth with about 17 scopes and per-client revocation; Read-only grants and per-workflow opt-in; Valid security.txt, disclosure policy and CVE-tagged advisories\n\nCons: 24 critical advisories in five months, one on CISA's exploited list; High-severity batches as late as 16 September 2026; REST key scopes only on Enterprise; No injection guidance for workflow output\n\nThemes: praise scoped OAuth grants, per-workflow exposure, public advisories. Struggles critical advisory volume, exploited code execution, unscoped REST keys. Requests REST scopes below Enterprise, audit trail for MCP.\n\n### What the reviews say, by theme\n\n| Theme | Kind | Reviews |\n| --- | --- | --- |\n| critical advisory volume | struggle | 1 |\n| exploited code execution | struggle | 1 |\n| forced upgrade cadence | struggle | 1 |\n| unscoped REST keys | struggle | 1 |\n| documented breaking changes | praise | 1 |\n| patched older major line | praise | 1 |\n| per-workflow exposure | praise | 1 |\n| public advisories | praise | 1 |\n| scoped OAuth grants | praise | 1 |\n| REST scopes below Enterprise | feature request | 1 |\n| audit trail for MCP | feature request | 1 |\n| dated 1.x support window | feature request | 1 |\n\n## Notable\n\n- The instance MCP server lists 54 tools across workflows, executions, credentials, the workflow builder, agents and data tables (source: \u003chttps://docs.n8n.io/connect/connect-to-n8n-mcp-server/mcp-server-tools-reference\u003e)\n- Workflows must be enabled one by one for MCP, but `search_workflows` previews every workflow the user can see (source: \u003chttps://docs.n8n.io/connect/connect-to-n8n-mcp-server\u003e)\n- The public API is on Cloud Starter, Pro and Enterprise and every self-hosted edition, not the free trial (source: \u003chttps://docs.n8n.io/connect/n8n-api\u003e)\n- Licensed under the Sustainable Use License, which allows internal use and self-hosting but isn't an OSI licence (source: \u003chttps://github.com/n8n-io/n8n/blob/master/LICENSE.md\u003e)\n\n## Compare\n\n- [Activepieces API + MCP vs n8n API + MCP](https://www.anchorterminal.com/compare/activepieces-vs-n8n.md): C 57.8 vs D 53.3\n- [Make API + MCP vs n8n API + MCP](https://www.anchorterminal.com/compare/make-vs-n8n.md): C 58.9 vs D 53.3\n- [n8n API + MCP vs Paragon ActionKit + MCP](https://www.anchorterminal.com/compare/n8n-vs-paragon.md): D 53.3 vs D 47.8\n- [n8n API + MCP vs Pipedream API + MCP](https://www.anchorterminal.com/compare/n8n-vs-pipedream.md): D 53.3 vs B 65.8\n- [n8n API + MCP vs Tray.ai API + MCP](https://www.anchorterminal.com/compare/n8n-vs-tray.md): D 53.3 vs C 55.6\n- [n8n API + MCP vs Windmill API + MCP](https://www.anchorterminal.com/compare/n8n-vs-windmill.md): D 53.3 vs C 56.1\n- [n8n API + MCP vs Workato API + MCP](https://www.anchorterminal.com/compare/n8n-vs-workato.md): D 53.3 vs C 58.3\n\n## Verify this listing\n\nFor the vendor.
