Why the edge:
- Reliability, Cosmic +43: Cosmic 90 (Graded on the hosted service with the hosted lines. Statuspage at cosmicstatus.com with API and Web Dashboard components (20). The history page shows no incidents in September, October or November 2026, and the newest incident in the feed is from 26 May 2025. The MCP server isn't a component, so 25 of 30. 100 requests a second with a burst of 200, timeouts and size limits are documented (15). 429 is documented and the error page says which codes to fix and not retry; no Retry-After guidance was found. Agent signup is idempotent (12 of 15). The security page says Enterprise has an SLA from 99.95 per cent uptime; the SLA page itself wasn't read (8 of 10). Hosted MCP is announced as available now, with no beta label (10). 20+25+15+12+8+10 = 90.); dotCMS 47 (Read with the local-software lines, since the MCP server is a stdio package the owner runs against their own instance. Official npm package with Node 20 or later and Bun stated (20). The monorepo has CI and the MCP app has vitest tests and smoke tests; whether they pass on main wasn't read (12 of 25). Open issues weren't read because the GitHub API refused us for its rate limit (10 of 25). 0.1.0 and 0.1.1 without release notes for the package (5 of 15). Pre-1.0, and the dev docs still call it beta (0). 20+12+10+5+0 = 47.)
- Schema & documentation, Cosmic +23: Cosmic 88 (openapi.json at www.cosmicjs.com covers 21 operations on 12 paths, each with a summary, a description and documented 401, 402, 404, 429 and 500 responses, though the docs describe more endpoints than it covers (revisions, AI, search); MCP tools have typed inputs (20 of 25). llms.txt and every docs page as Markdown (10). Tool descriptions say when to use each tool and when not to, such as never calling delete speculatively (18 of 20). 11 enums in the spec, typed metafields and validation messages (11 of 15). Examples on every API page and an error model with a sample (14 of 15). API v3 paths and a dated changelog (15). 20+10+18+11+14+15 = 88.); dotCMS 65 (The search tool exposes the instance's own OpenAPI spec, so the contract is machine-readable, though the tools themselves take JavaScript code (20 of 25). llms.txt and Markdown pages on dev.dotcms.com (10). The README says what each tool is for and gives examples; when not to use them isn't stated (12 of 20). Code strings rather than typed parameters for search and execute (4 of 15). Examples for both tools; error behaviour of the sandbox isn't documented (9 of 15). dotCMS changelogs are dated; the MCP package has no changelog (10 of 15). 20+10+12+4+9+10 = 65.)
- Security & auth, dotCMS +16: Cosmic 47 (Separate read and write keys per bucket, rotatable independently (25), less 10 because the docs give `read_key` as a query parameter on GET (15 of 30). Read-only MCP access by leaving out the write key, four user roles on every plan, and a delete tool told not to run speculatively; no approval step (14 of 20). Objects hold text written by people and AI generation writes into the bucket; no prompt-injection guidance was found (3 of 15). An append-only audit log of security-relevant actions on Workspace or Pro plans (10 of 15). No SOC 2, ISO 27001 or HIPAA by the security page's own statement, no security.txt, reports to support email (5 of 20). 15+14+3+10+5 = 47.); dotCMS 63 (JWT API tokens per user with role permissions and an expiry, created only by administrators (25 of 30). A read-only token can be made through a restricted role, but the MCP server asks for write permission; workflows support multiple-approval steps (14 of 20). Content returned from the CMS reaches the agent, and the sandbox isolates the token, with no prompt-injection guidance (5 of 15). Audit logging for API calls wasn't established in the pages read (5 of 15). A valid security.txt with PGP, a responsible disclosure policy with bounties, LTS security backports and a public list of known security issues, which is drawn by script and couldn't be read. No certification was found (14 of 20). 25+14+5+5+14 = 63.)
- Agent ergonomics, Cosmic +14: Cosmic 82 (24 tools, in the 11 to 30 band (15), plus 5 because omitting the write key gives a read-only subset (20 of 25). limit, props, depth, cursor pagination with `after`, status and locale filters (20). Status codes with specific messages and fix-or-retry guidance per code (17 of 20). readOnlyHint and destructiveHint on the MCP tools; no idempotency keys for writes, though agent signup is idempotent (14 of 20). Few required parameters, a TypeScript SDK and a CLI, no SDK in a second language found (11 of 15). 20+20+17+14+11 = 82.); dotCMS 68 (7 tools in code mode, so the definitions stay small (25). Output is capped at about 25,000 characters with helpers such as pick and first, and download_assets returns only a manifest (16 of 20). Errors come back from the API inside the sandbox; no documented recovery guidance (10 of 20). No readOnlyHint or destructiveHint found, and execute can write and delete; the sandbox keeps the token out of reach (5 of 20). Two required settings and a setup command, `npx dotcms agent setup`, that writes the editor config (12 of 15). 25+16+10+5+12 = 68.)
- Maintenance & community, Cosmic +11: Cosmic 86 (MCP server v1.7.1 was tagged on 2 November 2026 (30). v1.7.0 on 9 September and v1.7.1, plus changelog entries on 14 and 31 August, 1, 8, 10, 22 and 23 September and 5 and 9 October 2026 (20). A dated changelog, a Discord server and support email; GitHub issue activity wasn't read because the GitHub API refused us for its rate limit (12 of 25). com.cosmicjs/mcp in the official MCP registry under a domain namespace, though the registry has 1.6.0 while the repository is at 1.7.1 (15). CI, deploy and publish workflows in the MCP repository (9 of 10). 30+20+12+15+9 = 86.); dotCMS 75 (dotCMS core tagged v26.11.06-03 on 6 November 2026; the MCP package's last release was 0.1.1 on 2 September (30). Core tags several times a week (20). GitHub issues and a community forum; response times weren't read because the GitHub API refused us for its rate limit (10 of 25). Not in the official MCP registry; official JavaScript client libraries (8 of 15). The MCP package's dependencies and CI state weren't read (7 of 10). 30+20+10+8+7 = 75.)
- Payments & pricing, Cosmic +10: Cosmic 45 (No x402, MPP or L402 (0). Plan prices and quotas are public, with add-ons; no per-call price (10). Free plan with no card (20). Agent signup returns working bucket keys with no human signup; the human claims the project by emailed code within 14 days, so partial (15 of 20). 0+10+20+15 = 45.); dotCMS 35 (Scored with the self-hosted rule, with prices from the cloud plans. No x402, MPP or L402 (0). Cloud prices are on request only (0). Free with every capability under $5 million in revenue under the BSL, with no card (20). Self-hosting needs no dotCMS account, and tokens can be minted by API on one's own instance (15 of 20). 0+0+20+15 = 35.)
