BCMS vs Payload

BCMS 16

@thebcms/client 2.0.3 was published on 16 March 2026, more than 180 days ago, and no dated API or MCP change was found. The terms of 30 July 2026 and the 3.0.0 server card show the product is current, so 5 of 30. No dated releases or changelog entries in the last 90 days (0). No public changelog; support by contact form (4 of 25). Not in the official MCP registry; one current JavaScript client (4 of 15). The client hasn't been released since March (3 of 10). 5+0+4+4+3 = 16.

Payload 78

3.92.1 is tagged on 27 October 2026, 8 days before this check (30). Nine stable releases from 3.87.1 on 6 August to 3.92.1 on 27 October 2026, with 4.0.0 betas alongside, which don't count (20). 225 issues opened against 116 closed since 10 July, 140 open issues awaiting triage and 763 open pull requests, per the 8 October check (12 of 25). @payloadcms/sdk ships with each release but is beta and TypeScript only, and the official MCP registry has no Payload entry, which fits a plugin that runs inside each install (8 of 15). CI runs on every push. The latest 3.x run had failed on 8 October 2026, and runs couldn't be read on 4 November (8 of 10).

BCMS 15

Graded on BCMS Cloud with the hosted lines. No status page was found (0) and no incident history could be read (5). The terms refer to rate limits, but no numbers were found in the docs (0). No 429 or retry guidance was found (0). No SLA; Enterprise is by quote (0). The MCP server card says version 3.0.0 and nothing is labelled beta (10). 0+5+0+0+0+10 = 15.

Payload 76

Read with the local-software lines, since the graded surface is software its owner hosts. Official npm packages, with Node.js ^22.23.4 || >=24.22.1 in engines and in the installation docs since 3.92.0 (20). A public ci workflow runs unit, type, integration and end-to-end tests on every push to 3.x. GitHub's pages and API couldn't be read on 4 November, so the result is unread (15 of 25). 499 issues were open on 8 October, 140 of them awaiting triage, with 225 opened and 116 closed since 10 July 2026, not re-read (12 of 25). A written semver policy marks breaking commits with ! and lists them in release notes, but lets security fixes and experimental APIs change in minor releases (14 of 15). 3.x is the stable line, with 4.0 in beta (15).

BCMS 36

45 MCP tools, more than 30 (5). We added 3 because keys without schema permission hide the schema tools (8 of 25). No pagination or filter parameters were found in the docs read (6 of 20). Error guidance covers 403 and permission errors only (8 of 20). Annotations weren't readable; entry history and trash give a way back, and the docs say to list and confirm ids before deletes (6 of 20). One JavaScript client and a CLI (8 of 15). 8+6+8+6+8 = 36.

Payload 64

Four MCP tools per enabled collection and two per global, so five collections give 20 tools, the 11 to 30 band (15). We added 7 because the owner enables collections and operations one by one, each key narrows the list again, and find tools default to 10 documents at depth 0 with select (22 of 25). Page-based pagination with limit and page, 17 where operators, sort, select and populate (20). REST errors come back in an errors array and MCP tools return a text line beginning Error:. Neither format is documented as a list an agent can match on (10 of 20). No idempotency keys, and no readOnlyHint or destructiveHint in the plugin source. An update by id is repeatable (4 of 20). Few required parameters and sensible defaults. The one official client, @payloadcms/sdk for TypeScript, is labelled beta (8 of 15).

BCMS 50

The docs link an OpenAPI reference at app.thebcms.com/open-api-docs, but that host's robots.txt disallows every path, so it wasn't read. The MCP tool schemas need a session (10 of 25). llms.txt, docs llms.txt, llms-full.txt, Markdown pages and a public SKILL.md (10). llms.txt says when to use BCMS and when not to, and the MCP page gives each tool group's purpose (12 of 20). Input typing couldn't be checked (5 of 15). Curl and JavaScript examples, and troubleshooting for 403 and permission errors (7 of 15). API v3 paths and a 3.0.0 server card, with no changelog found (6 of 15). 10+10+12+5+7+6 = 50.

Payload 70

No OpenAPI file is published or generated by the core packages, because endpoints depend on each project's config. Every MCP tool carries a typed input schema built from the collection's fields, and the GraphQL schema is generated from the same config (20 of 25). llms.txt per major version, llms-full.txt and a Markdown copy of every docs page (10). Default MCP tool descriptions are one line, such as Create a document in a collection., unless the owner writes one in the plugin config. The docs tell owners to do so (10 of 20). Field inputs are typed with bounds on limit and depth, but where is JSON passed as a string. select became an object in the MCP find tools in 3.91.0 (10 of 15). REST operations show a request and a response each. No reference page for error responses or status codes was found (8 of 15). Semver, release notes on GitHub and separate docs per major version. REST paths carry no version (12 of 15).

BCMS 39

Keys are scoped per template and media and can be revoked and rotated (25), less 10 because the MCP key is accepted only as ?mcpKey= in the URL and REST examples pass apiKey the same way (15 of 30). Scoped keys, schema tools gated by key, and scoped delete permission; no approval step (12 of 20). Entries hold text written by people and no prompt-injection guidance was found (3 of 15). Entry history and log history (2 days on Hobby, 30 on Pro) let the operator see what an agent changed (9 of 15). No security.txt, disclosure policy or certification was found (0). 15+12+3+9+0 = 39.

Payload 57

REST keys are per user, revocable and regenerable, shown once, and limited by that user's access control down to field level. MCP keys carry per-collection, per-operation switches. Both travel only in the Authorization header. Neither expires, and there is no OAuth (24 of 30). A find-only MCP key is a config switch away and the collection's access control still runs under it. Nothing asks a person to approve a delete or a publish in the free edition (14 of 20). Documents hold text written by other people, and no prompt-injection guidance was found. overrideResponse can strip fields before they reach a model (3 of 15). Versions record each change, and onEvent and verboseLogs expose MCP calls to the owner's own logging. No built-in audit log (7 of 15). SECURITY.md gives a reporting address and, since 16 October 2026, says Payload pays no monetary rewards and runs no bug bounty. Advisories are published on GitHub with affected versions, patches and workarounds. No security.txt or SOC 2 statement was found (9 of 20).

BCMS 30

No x402, MPP or L402 (0). Plan and seat prices are public; no per-call prices (10). 14-day trial with no card on every plan (20). Signup with GitHub or Google in a browser, keys made in the dashboard (0). 0+10+20+0 = 30.

Payload 45

Scored with the self-hosted rule. No x402, MPP or L402 (0). The software is free under MIT, which the get-started page states. The only paid option, Enterprise, is priced by sales, and Payload Cloud is closed to new projects, so 15 of 20. No card and no account at Payload are needed (20). npx create-payload-app installs it, but the docs create REST and MCP API keys in the admin panel, so half (10).
