Ahead on

  • Payments & pricing, 30 against 10

Also in its favour

  • A hosted endpoint, with nothing to install

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Schema & documentation Mixpost API + MCP +49

Mixpost API + MCP 76

OpenAPI 3.1 linked from the API docs (25). No llms.txt found (0). The MCP tools page groups 30 tools and labels each read, write or destructive (12). Inputs typed in the spec (12). A dedicated errors page, consistent JSON error shapes, and 422 with errors.limit for plan limits (12). Public release notes for every Pro version (15).

Repostit 27

MCP reading, since the connector is the only surface an outside agent reaches; no public REST API, developer page, OpenAPI file, SDK or package was found in the help centre, /whats-new/, the sitemap, llms.txt, GitHub, npm or the MCP registry. No tool names or input schemas are published anywhere, and no session was opened to read them (0 of 25). llms.txt exists, but it is a Rank Math index of site URLs that includes theme placeholder entries, and help articles are HTML only (5 of 10). The Claude connector page says what each step is for and when not to use it, list accounts before choosing a destination, a Brief saves a draft and neither publishes nor schedules, publishing applies to every destination in a Brief, Queued is not delivery, future-content workflows publish once active while existing-content ones import for review (8 of 20). Inputs are described in prose only, formats per destination, JPEG, PNG or WebP up to 20 MB, carousel caps of 4, 10 and 20 by network, media at a downloadable HTTPS URL and a timezone with every scheduled time (4 of 15). Plain-language example requests and per-network failure reasons written for people; no example tool call, response or error shape (5 of 15). The endpoint path carries v1.1 and the registry holds 2026.10.17 and 2026.10.23; /whats-new/ is undated and no changelog was found (5 of 15). 0+5+8+4+5+5 = 27.

Reliability Mixpost API + MCP +44

Mixpost API + MCP 70

Scored on the checklist for software you run yourself, since Pro installs into your own Laravel app and its uptime is whatever your server gives it. Mixpost Cloud has no status page we could find. Installs from Inovector's Composer repository with PHP 8.2 or later stated (20). Lite runs a public test workflow on PHP 8.2 and 8.3, and Pro's CI isn't public (10). The Lite repo has 27 open issues, including bug reports from December 2025 to June 2026 with no maintainer replies visible, and Pro's tracker is private (10). Release notes per version, with v7.0.0 flagged as breaking (15). Past 1.0, at Pro v7.0.3 (15).

Repostit 26

Hosted reading, for the connector and the service behind it. No status page was found. None is linked from the help centre, the contact page, the footer or the troubleshooting articles, and https://repostit.io/status/ did not load through our reader, which also fails on the home page (0). No readable incident history, so the floor (5). Repostit publishes posting quotas rather than request limits, 10 posts on the trial, 10 video posts a month on Basic, existing-content workflows up to 5 posts a day, plus per-network rules and 20 MB images through the connector; no request rate for the connector, and the terms only bar automated access faster than a human (6 of 15). No 429 or overload handling is documented. The Claude connector page says Queued means accepted, not delivered, and to check the existing result before retrying to avoid duplicate posts, and Brief locks queued posts against a second send; no idempotency key and no page says failed posts are retried (5 of 15). No SLA; the terms (7 March 2025) let Repostit modify or discontinue the service at any time and say nothing on uptime (0). The connector carries no beta label and its registry entry is active (10). 0+5+6+5+0+10 = 26.

Agent ergonomics Mixpost API + MCP +28

Mixpost API + MCP 53

30 MCP tools with no toolsets (15). Some list endpoints paginate and some don't, per the API docs (12). Laravel-style JSON errors with field messages and 422 for validation (15). No idempotency keys, and the read, write and destructive labels live in the docs rather than as MCP annotations. unschedule-post and restore-post give safe ways back (6). No official SDKs, only an n8n community node (5).

Repostit 25

MCP reading. The tool count is not published. The connector pages describe seven actions (list accounts, create, schedule and publish a Brief, check delivery, create a workflow, send a connection link), which suggests a small set, but the definitions were not read, so a middle reading rather than full marks (10 of 25). No pagination, filtering or output-size controls are documented (0 of 20). Delivery checks report a result per destination with public links when the network gives one, and the help centre lists failure reasons per network, but no error codes or connector error messages are documented (5 of 20). No idempotency key and no readOnlyHint or destructiveHint seen; Briefs start as drafts, queued Briefs are locked against a second send, Manual workflows hold posts for approval and the guidance says to check before retrying (6 of 20). Requests are made in plain language with few stated requirements (an HTTPS media URL, a timezone); no SDK in any language (4 of 15). 10+0+5+6+4 = 25.

Transparency & trust Mixpost API + MCP +22

Mixpost API + MCP 51

The API and MCP live in Pro and Enterprise, which are proprietary with clear licence terms and a perpetual fallback licence. Lite is MIT (15). Privacy policy from INOVECTOR DIGITAL S.R.L. of Moldova names Hetzner, DigitalOcean, PayPal and Sentry, but has no date, no DPA and vague retention (12). v7.0.0 is flagged breaking and the MIXPOST_CORE_PATH default change is documented, with no formal deprecation policy (8). Cloud subprocessors and countries named. We found no statement on whether self-hosted installs report anything back (10).

Repostit 29

Closed service. The terms of service (effective 7 March 2025, no revision since) name Repostit LLC of Newark, Delaware, with Delaware law and arbitration, take a non-exclusive licence to content only to run the service and say fees are non-refundable; every footer says Repostit, Inc., and the terms do not mention the connector (12 of 30). The privacy policy (29 July 2026) keeps data until the account is deleted or as needed, with no periods, deletes Pinterest credentials on disconnect but says nothing of other networks' tokens, names no DPA, and does not mention the connector or its 90-day offline access; the account deletion article gives no timeline and leaves network-side access to the user (10 of 30). No deprecation policy or dated notices; the terms promise notice of significant changes and the ChatGPT page names a pending version 1.1 without a date (3 of 20). Subprocessors are 'hosting providers, analytics services', unnamed, with transfers outside the user's country and no locations; the Tawk.to chat on the contact page and the Google Cloud Run host of the connector are not named in the policy (2 of 20). 12+10+3+2 = 27.

Payments & pricing Repostit +20

Mixpost API + MCP 10

No x402 (0). Pro is $299 once and Enterprise $1,199 once, both public, with no per-call price (10). Lite is free but has no API or MCP, and Pro has a 14-day money-back guarantee rather than a trial (0). A person has to buy a licence and install the software (0).

Repostit 30

No x402, MPP or L402 on any page read (0). Plan prices are public without a login, Basic $5 a month, Starter $14 or $10 yearly, Influencer $29 or $20, Agency $149 or $99, with no per-call or per-post price (10 of 20). A 14-day trial with no credit card on every plan, stated on the pricing page, the trial article and the refund page (20). A person signs up in a browser, connects each network in Repostit and approves the connector; no keyless or programmatic route (0). 0+10+20+0 = 30.

Maintenance & community Mixpost API + MCP +7

Mixpost API + MCP 63

Pro v7.0.3 on 30 September 2026 (30). v7.0.0, v7.0.1, v7.0.2 and v7.0.3 between 26 and 30 September, after v6.3.0 and v6.3.1 in July and August (20). The public Lite tracker shows no maintainer replies on recent issues, and Pro support is private (8). No official SDKs or registry entry (0). Lite has CI but last released 2.6.0 on 13 March 2026 (5).

Repostit 56

Closed service. The latest registry version is 2026.10.23, published 23 October 2026, and the connector article was updated 22 October 2026 (30). Dated changes in the last 90 days are the two registry versions of 17 and 23 October 2026; /whats-new/ is undated and the ChatGPT app's 1.1.0 (per the 3 November listing check) carries no date, so fewer than three dated releases (10 of 20). Support is email and weekday chat, 9am to 5pm Eastern, with replies within 24 hours; no public changelog with dates, forum or issue tracker (6 of 15). In the official MCP registry as io.github.hax98/repostit, a GitHub-verified namespace of a personal account; the entry links Repostit's own pages and its address matches the vendor's connector page, but no first-hand page ties the account to the company, so partial credit (10 of 15). No packages, public code or CI to judge (0 of 10). 30+10+6+10+0 = 56.

How the scores have moved

Verdicts

Mixpost API + MCP

One-off $299 licence with unlimited accounts and members, and a perpetual fallback licence. No API or MCP in the free Lite edition.

Repostit

An OAuth connector lets an agent list accounts, draft and schedule posts, build reposting workflows and check delivery, with drafts saved before anything publishes and a 14-day trial without a card. Tool names, schemas, scopes and error shapes are unpublished, the endpoint sits on a Cloud Run host, and there is no status page, public API or named subprocessor.

Before you call either

Mixpost API + MCP

  1. Call list-workspaces first. Workspace endpoints sit under /api/{workspaceUuid}
  2. Check MIXPOST_CORE_PATH. It's empty by default from Pro v7 but defaults to mixpost in older versions and Lite
  3. Create the token as a Viewer-role user when the agent only needs to read
  4. Use unschedule-post rather than delete-post when a person wants a post pulled back to draft
  5. Expect HTTP 422 with an errors.limit entry when a Cloud plan limit is hit

Repostit

  1. List connected accounts first and confirm names and platforms with the user before choosing destinations; a missing account must be connected in Repostit Connections, not through the agent.
  2. Pass media as a downloadable HTTPS URL, never a local filename, and give every scheduled time with an explicit timezone.
  3. Treat Queued as accepted, not published; check delivery status and public links before reporting success, and check the existing result before any retry to avoid duplicate posts.
  4. Creating a future-content workflow makes it publish on its own once active; prefer existing-content workflows or Manual mode when the user wants to review first.
  5. On the trial, each destination counts as one of 10 posts and Basic allows 10 video posts a month; ask before fanning one Brief out to many networks.
