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.

Maintenance & community Repostit +56

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.

SocialCannon 0

No dated release history, official registry identity, support-response sample or dependency audit established (0). This is an evidence gap, not a claim of inactivity.

Agent ergonomics SocialCannon +55

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.

SocialCannon 80

Cursor pagination and compact response envelopes (20), filters and output controls (20), detailed failure and conflict states (20), idempotency on selected write routes (15), client examples and automatic MCP token refresh (5).

Schema & documentation SocialCannon +28

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.

SocialCannon 55

No public machine-readable contract verified (0) and no Markdown index established (0). Endpoint purposes and platform constraints (20), parameter descriptions and validation rules (15), examples and actionable errors (15), versioned v1 routes but no dated changelog verified (5).

Security & auth SocialCannon +21

Repostit 44

OAuth with dynamic client registration and no client secret, per Repostit's Claude connector page, with offline access that renews for up to 90 days from the first authorisation; social-network sign-ins stay in Repostit and provider tokens are not passed to the assistant. PKCE S256 is stated only in third-party metadata. No scopes are named; the page lists the permissions shown at sign-in (read accounts, create workflows and Briefs, schedule or publish, read delivery status). Revocation is by disconnecting in the client or asking support (18 of 30). A Brief is saved as a draft, Manual workflows wait for approval, and the help article says the assistant shows each step for confirmation before publishing (on ChatGPT 'may ask', depending on the client); no read-only mode, and an activated future-content workflow publishes on its own (8 of 20). Tools return the user's own accounts, Briefs and delivery results and read no comments or messages (10). Assistant-created posts appear under Post with a Comments & Activity log of each step, and Post History shows each network's response; no per-call log for the connector (8 of 15). security.txt did not load through our reader, and no disclosure policy, bug bounty or certification appears on any page read (0 of 20). 18+8+10+8+0 = 44.

SocialCannon 65

Scoped client credentials and short-lived JWTs (25), separate read/write/delete scopes (20), no prompt-injection mitigation established (0), post and engagement state visible to the operator (10), documented encryption and secret hashing without independent certification established (10).

Transparency & trust SocialCannon +20

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.

SocialCannon 49

Closed service with terms (15), privacy and data deletion disclosures (15 of 30), no minimum deprecation period established (0), named hosting and payment processing (10 of 20).

Reliability SocialCannon +19

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.

SocialCannon 45

No public incident history established (5). Numeric per-plan rate limits (15), Retry-After and bounded scheduler retry guidance (15), production API documented (10). No public standard SLA established (0).

SocialCannon

Verdicts

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.

SocialCannon

Scoped credentials and published rate limits. X quotas remain on paid plans with unlimited posts.

Before you call either

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.

SocialCannon

  1. Use the sandbox before publishing to a real account.
  2. Check X quota separately from the general post allowance.
  3. Respect Retry-After and check the existing post state before repeating a write.
