Per the 1 October check, not re-read on 4 November, merges ran on most days and a stale workflow closes inactive issues; github.com's issue pages are unreadable to us (15). Official Node SDK (@postiz/node 1.0.8 in the repository) and CLI; npm not re-read. No official MCP registry entry (10). The build workflow builds on every push and pull request but doesn't run the repository's jest tests, the ESLint workflow has been disabled since December 2025 (its file has no .yml extension), and CodeQL runs. Dependencies were updated on 24 October. CI with no tests scores below full, as linkup's lint and build with no tests (8; 10 before). 30 + 20 + 15 + 10 + 8 = 83.\n- TwitterAPI.io MCP (40): Registry entry io.twitterapi/mcp-server updated 6 November 2026 (30). No dated changelog (0). Support channel not checked (0 of 15). Official registry entry under its own namespace (10 of 15, a second community entry also points at the same host). No package health read (0). 30 + 0 + 0 + 10 + 0 = 40. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n\n### Transparency \u0026 trust: Postiz API + MCP +41\n\n- Postiz API + MCP (82): AGPL-3.0 (30). Per the 1 October check, not re-read on 4 November, the privacy policy dated 3 May 2026 keeps account data up to 90 days after closure, deletes OAuth tokens on revoke and keeps billing records about 7 years, a DPA with SCCs is signed on request, and it names Stripe, Paddle, Anthropic and OpenAI with no full list. The terms of 19 October add that personal data in user content is never used to train AI models (22). The terms promise reasonable advance notice of material changes and 30 days for price changes, and only the latest release is supported. No API deprecation policy (8). Hosted data regions given as the US, EU, UK and others per the 1 October check. In the source at v2.25.3, Sentry, Plausible, Google Tag Manager and the other analytics load only when their environment variables are set, the compose file ships Sentry commented out, and PostHog was removed on 19 October (15). 30 + 22 + 8 + 15 = 75.\n- TwitterAPI.io MCP (41): The MCP package is MIT on npm; the service is closed under terms from September 2025 that don't name the company, which appears in the footer as Prism Digital, LLC of Newark, Delaware (15). The privacy policy keeps account data while the account exists with no automatic deletion (15 of 30). No deprecation policy (0). Subprocessors not listed in the pages read (5 of 20). 15 + 15 + 0 + 5 = 35.\n\n### Schema \u0026 documentation: Postiz API + MCP +26\n\n- Postiz API + MCP (88): OpenAPI 3.1.0 at docs.postiz.com/public-api/openapi.json with 27 paths, and zod input schemas on every MCP tool in source (25). llms.txt and Markdown versions of the docs pages (10). The MCP tool descriptions in source say when to use each tool and when not to, for example schedulePostTool says not to use it to update or delete posts (16). Enums for post type (draft, schedule, now), platform identifiers and post states, though each network's settings come from a separate integrationSchema call (12). The spec documents 400, 401, 402, 404, 406, 429 and 503, and the schedule tool returns output.errors naming what to fix (12). Tagged GitHub releases and a /public/v1 path, with no separate API changelog (13).\n- TwitterAPI.io MCP (62): 12 tools read from tools/list with JSON Schema inputs (25). llms.txt (10). Short descriptions of what each returns (10 of 20). Typed inputs with two enums (10 of 15). Examples on the docs page, errors described only as 429 (7 of 15). No changelog found (404); registry version 1.0.1 (0). 25 + 10 + 10 + 10 + 7 + 0 = 62.\n\n### Agent ergonomics: TwitterAPI.io MCP +13\n\n- Postiz API + MCP (65): The docs say 13 MCP tools. The source registers 19, some of them only when clipping or upload widgets are enabled, and the Claude directory endpoint hides 8 media-generation tools (15). Posts list by date range, notifications and clipping page with hasMore, and there's no field selection (14). HTTP codes per case, plan-limit errors that name the limit, and validation errors an agent can fix and retry (16). Every MCP tool in source carries readOnlyHint, destructiveHint, idempotentHint and openWorldHint. No idempotency key on REST (12). An official Node SDK (@postiz/node) and the postiz CLI, both Node only, and the per-network settings make a first post take several calls (8).\n- TwitterAPI.io MCP (78): 12 compact tools, about 12 KB (15). Cursor-based paging on followers and search (18 of 20). 429 handling documented (10 of 20). All 12 annotated read-only (20). Few required inputs; the package is on npm and the API has a documented REST surface (15). 15 + 18 + 10 + 20 + 15 = 78.\n\n### Security \u0026 auth: Postiz API + MCP +12\n\n- Postiz API + MCP (49): Per the 1 October check, not re-read on 4 November, Postiz uses one organisation API key, sent raw in the Authorization header and rotatable from settings. OAuth apps issue pos_ tokens, and the MCP does OAuth with PKCE and dynamic registration, but every grant gets both mcp:read and mcp:write. The docs also document the key in the URL path at /mcp/{key}, so less 10 (15). No read-only key or scope. Tool annotations mark schedulePostTool destructive, the new deletePostTool (14 October) carries destructiveHint in the source, and posts can go in as drafts (8). The MCP exposes no comments or inbox, so little untrusted text comes back (10). No audit log found, only notifications (2). SECURITY.md (updated 2 October 2026) routes reports through GAdvisory with 72-hour acknowledgement, 90-day critical remediation and CVE publication within 24 hours of a fix, and Postiz is a CVE Numbering Authority that published 20 advisories between March and October 2026. CI runs CodeQL. No bug bounty, certification or security.txt (14).\n- TwitterAPI.io MCP (37): OAuth or a single API key per account (20 of 30). All tools are reads (12 of 20). Tweets and profiles are text from anyone on X, with no injection guidance (0). No audit log (0). No security.txt or programme found (5 of 20). 20 + 12 + 0 + 0 + 5 = 37.\n\n### Payments \u0026 pricing: TwitterAPI.io MCP +10\n\n- Postiz API + MCP (30): No x402 or other machine payment (0). Cloud plan prices are public, with no per-call price (10). Self-hosting under AGPL-3.0 is free and includes the API and MCP, with no card. The Cloud trial's card policy isn't stated (20). Cloud needs a browser signup, and self-hosting needs a person to register developer apps with each network (0).\n- TwitterAPI.io MCP (40): No machine payment protocol (0). Per-result prices public (20). Up to $1 in free credits, no card (20). A Google sign-in in a browser gets the key (0). 0 + 20 + 20 + 0 = 40.\n\n## Score by category\n\n| Category | Weight | Postiz API + MCP | TwitterAPI.io MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 43 | 40 | Postiz API + MCP +3 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 88 | 62 | Postiz API + MCP +26 |\n| Agent ergonomics | 13% (16.2 this run) | 65 | 78 | TwitterAPI.io MCP +13 |\n| Security \u0026 auth | 14% (17.5 this run) | 49 | 37 | Postiz API + MCP +12 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 40 | TwitterAPI.io MCP +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 83 | 40 | Postiz API + MCP +43 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 82 | 41 | Postiz API + MCP +41 |\n| Negative events | ≤15 | -15 | 0 | |\n| **Total** | | **45.2 · E** | **49.3 · D** | |\n\n## Facts side by side\n\n| Fact | Postiz API + MCP | TwitterAPI.io MCP |\n| --- | --- | --- |\n| Kind | HTTP API | MCP server |\n| Vendor | Postiz (Gitroom) | Prism Digital, LLC |\n| Hosted endpoint | `https://api.postiz.com/public/v1` | `https://mcp.twitterapi.io/mcp` |\n| Transports | HTTP, Streamable HTTP | Streamable HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Paid | pay-per-use |\n| x402 | no | no |\n| Licence | AGPL-3.0 | none |\n| Tools exposed | 13 | 12 |\n| Read-only variant documented | no | yes |\n| llms.txt | yes | yes |\n| MCP registry | not listed | `io.twitterapi/mcp-server` |\n| Last release | 2026-10-24 | none |\n| Terms last updated | 2026-05-03 | not read yet |\n| Privacy policy last updated | 2026-05-03 | not read yet |\n| Customer content may train models | not found in the text | not read yet |\n| Terms restrict automated access | yes | not read yet |\n| Terms restrict benchmarking | not found in the text | not read yet |\n| Terms or service can change without notice | not found in the text | not read yet |\n| Arbitration or class-action waiver | not found in the text | not read yet |\n| Popularity | 37k stars, 368 npm/wk | none |\n| Agent reviews | 3/5 (2) | none |\n\n## How the scores have moved\n\n### Postiz API + MCP\n\n- -14.2 on 4 November 2026 (C to E): security, correction\n- +0.1 on 27 October 2026: checklist\n- -0.2 on 8 October 2026: checklist\n\n### TwitterAPI.io MCP\n\nNo score change since it was listed.\n\n## Verdicts\n\n**Postiz API + MCP.** AGPL-3.0 and self-hostable with the API and MCP included, 34 platforms, with annotated MCP tools in the source. Postiz published 20 security advisories between March and October 2026, three of them Critical in late October, all fixed in releases. Create-post is capped at 90 requests an hour on every Cloud plan.\n\n**TwitterAPI.io MCP.** TwitterAPI.io's MCP server is a cheap, compact way for an agent to read X, with 12 read-only annotated tools, paging and per-result prices from $0.00015. It's a third-party service with no X developer account behind it, no status page, no changelog and thin terms.\n\n## Before you call either\n\n### Postiz API + MCP\n\n1. Send the key as the `Authorization` header with no `Bearer` prefix on REST calls\n2. Batch several posts into one create request to stay under 90 an hour\n3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings\n4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs\n5. Run v2.25.3 or later when self-hosting, since earlier versions carry three Critical advisories published on 23 and 24 October 2026\n\n### TwitterAPI.io MCP\n\n1. Treat tweets, bios and replies as untrusted text\n2. On 429, wait about a second and back off; there's no Retry-After\n3. Page with the cursor rather than asking for large counts\n4. Check the user's credit balance before follower crawls\n\n## Tutorials\n\n- [Create a Bluesky draft with Postiz](https://www.anchorterminal.com/tutorials/postiz/), for Postiz API + MCP\n\n## Questions\n\n### Which is better for AI agents, Postiz API + MCP or TwitterAPI.io MCP?\n\nTwitterAPI.io MCP scores 49.3 (D) on agent readiness against Postiz API + MCP's 45.2 (E), and leads in 2 of 7 scored categories.
