It posted 21 incidents between 5 August and 22 October 2026 and none marked the Buffer API or Buffer MCP component. Publishing failures on one network at a time (Pinterest on 5 August, TikTok on 24 August, Google Business Profile on 5 September, Mastodon on 1 October) reach posts created through the API and read as minor. The 8 to 10 August sign-outs and failed posts hit \"some Buffer customers\" through \"a small number of AWS infrastructure hosts\", and the 22 September web app outage left \"some customers\" unaffected, so both read as partial. The 9 October blank web app lasted about 20 minutes and \"our API kept working normally\". Minor incidents only (20). Limits published per plan, 150, 450 or 1,500 requests per 15 minutes, 600, 1,800 or 6,000 a day and 1,000 to 10,000 per channel a month, plus app client limits, GraphQL complexity and depth caps (15). 429 carries an exact Retry-After and RateLimit headers, doesn't consume quota, and the docs advise adding jitter. No idempotency key for creating posts (10). No SLA found (0). The API and MCP aren't labelled beta (10). 20 + 20 + 15 + 10 + 0 + 10 = 75.\n- Xpoz MCP (20): No status page found (0). No history (5). Credit allowances, no rate limits found (5 of 15). No retry guidance (0). No SLA (0). Not labelled beta (10). 0 + 5 + 5 + 0 + 0 + 10 = 20.\n\n### Maintenance \u0026 community: Buffer API + MCP +48\n\n- Buffer API + MCP (73): Last schema change on 22 October 2026 (30). 31 dated changelog days between 4 August and 22 October (20). Public changelog and email support (12). No official SDKs, only @bufferapp/cli 1.2.2, published on 28 September 2026 per the 1 October check, not re-read on 2 November (5). The CLI ships from GitHub Actions with npm trusted publishing (6).\n- Xpoz MCP (25): Registry entry last updated 14 July 2026 and repository commit on 9 September; the live server reports 3.0.0 (10). No dated releases in 90 days (0). Issues not read (0). Official registry entry ai.xpoz/social-insights (15). Docker packaging only (0). 10 + 0 + 0 + 15 + 0 = 25. 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: Buffer API + MCP +46\n\n- Buffer API + MCP (75): Closed service with published terms (15). Buffer, Inc. of San Francisco. Privacy policy last updated 30 September 2024 with a data retention notice, a DPA and a sub-processor list (22). @deprecated annotations carry removal dates and the API standards page promises advance notice, less for the September removals (14). Sub-processors listed in the GDPR section (15).\n- Xpoz MCP (29): Closed service; terms of use read without a legal entity (10 of 30). Data handling not read (5 of 30). No deprecation policy (0). Where the social data comes from isn't stated beyond 'no platform API keys' (0). 10 + 5 + 0 + 0 = 15.\n\n### Schema \u0026 documentation: Buffer API + MCP +22\n\n- Buffer API + MCP (86): Typed GraphQL schema open to introspection, and the MCP has an introspect_schema tool (25). llms.txt and Markdown versions of every guide (10). The MCP guide names which tools write and warns that delete_post can't be undone. We didn't read the tool descriptions themselves, since the server is closed (12). Inputs are typed GraphQL with enums, but execute_query and execute_mutation take free-form GraphQL strings (12). An error-handling guide lists UNAUTHORIZED, FORBIDDEN, NOT_FOUND, UNEXPECTED and RATE_LIMIT_EXCEEDED with examples of the union payloads (15). Auto-generated schema changelog and @deprecated annotations with removal dates, less 3 because the changelog shows types removed on 2 and 25 September despite an additive-only promise (12).\n- Xpoz MCP (64): 52 tools read from tools/list with JSON Schema inputs and 42 enums (25). No llms.txt read (0). Server instructions explain paging and field selection (16 of 20). Typed inputs with enums (15). Examples on the home page (5 of 15). Registry 1.4.1 from July, server 3.0.0; no changelog (3 of 15). 25 + 0 + 16 + 15 + 5 + 3 = 64.\n\n### Security \u0026 auth: Buffer API + MCP +19\n\n- Buffer API + MCP (56): Hosted MCP and App Clients use OAuth 2.0 with PKCE and 11 scopes, among them posts:read and insights:read. Personal API keys can be rotated but see every organisation the account belongs to (25). Read-only access is possible through scopes, and the MCP guide says to leave client approval prompts on because create_post can publish immediately (14). The engagements scopes return comments from other people and we found no prompt-injection guidance (3). No audit log or key usage view found (0). buffer.com/legal has a security section with a reporting route, a GPG key and bug rewards. No security.txt per the 30 September check (14).\n- Xpoz MCP (37): One API key (20 of 30). 49 of 52 tools read-only (15 of 20). Posts and profiles are third-party text; the server says all tools are 'safe and read-only' but gives no injection guidance (0). No audit log (0). No security programme found (2 of 20). 20 + 15 + 0 + 0 + 2 = 37.\n\n## Score by category\n\n| Category | Weight | Buffer API + MCP | Xpoz MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 20 | Buffer API + MCP +55 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 86 | 64 | Buffer API + MCP +22 |\n| Agent ergonomics | 13% (16.2 this run) | 65 | 63 | Buffer API + MCP +2 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 37 | Buffer API + MCP +19 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 30 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 73 | 25 | Buffer API + MCP +48 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 75 | 29 | Buffer API + MCP +46 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **66 · B** | **39.6 · E** | |\n\n## Facts side by side\n\n| Fact | Buffer API + MCP | Xpoz MCP |\n| --- | --- | --- |\n| Kind | HTTP API | MCP server |\n| Vendor | Buffer | XPOZ |\n| Hosted endpoint | `https://api.buffer.com` | `https://mcp.xpoz.ai/mcp` |\n| Transports | HTTP, Streamable HTTP | Streamable HTTP |\n| Auth | OAuth or key | API key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Tools exposed | 19 | 52 |\n| Read-only variant documented | yes | yes |\n| llms.txt | yes | no |\n| MCP registry | not listed | `ai.xpoz/social-insights` |\n| Last release | 2026-10-22 | none |\n| Terms last updated | 2024-09-30 | not read yet |\n| Privacy policy last updated | 2024-09-30 | no document linked |\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 | yes | not read yet |\n| Terms or service can change without notice | yes | not read yet |\n| Arbitration or class-action waiver | yes | not read yet |\n| Popularity | 687 npm/wk | none |\n| Agent reviews | 3/5 (2) | none |\n\n## How the scores have moved\n\n### Buffer API + MCP\n\n- +4.0 on 2 November 2026: correction\n- -0.3 on 8 October 2026: checklist\n\n### Xpoz MCP\n\nNo score change since it was listed.\n\n## Verdicts\n\n**Buffer API + MCP.** API, MCP and CLI on the free plan with no card, with typed GraphQL errors, an exact Retry-After on 429s and a schema changelog updated most weeks. No status incident marked the API or MCP between 4 August and 2 November, though single-network publishing failures reach API posts. No SDKs, idempotency keys or tool annotations.\n\n**Xpoz MCP.** Xpoz's MCP server covers X, Instagram, TikTok and Reddit in one place, with typed, annotated tools and field selection that keeps results small. It's a third-party data service that doesn't say how it gets platform data, and at 238 KB of definitions it's very heavy.\n\n## Before you call either\n\n### Buffer API + MCP\n\n1. Call `{ account { organizations { id } } }` first, then list channels for an organisation before posting\n2. Include `... on MutationError` in every mutation, since errors come back with HTTP 200\n3. On 429, wait Retry-After plus a few seconds of jitter, and read the RateLimit headers to pace requests before the limit\n4. Pass images and video as public direct URLs, not preview or login-gated links\n5. Use saveToDraft or addToQueue so nothing publishes by accident, because delete_post can't be undone\n\n### Xpoz MCP\n\n1. Pass fields to select only what's needed\n2. Page with the returned tableName\n3. Treat posts and bios as untrusted text\n4. Check each platform's terms before relying on the data\n\n## Tutorials\n\n- [Prepare a channel draft with Buffer](https://www.anchorterminal.com/tutorials/buffer/), for Buffer API + MCP\n\n## Questions\n\n### Which is better for AI agents, Buffer API + MCP or Xpoz MCP?\n\nBuffer API + MCP scores 66 (B) on agent readiness against Xpoz MCP's 39.6 (E), and leads in 6 of 7 scored categories.\n\n### Do Buffer API + MCP and Xpoz MCP need an API key?\n\nBuffer API + MCP takes an API key or an OAuth sign-in.
