Generally available, and the MCP server since 20 April 2026 (10). 20 + 10 + 15 + 15 + 10 + 10 = 80.\n- Tigris (35): Status page on incident.io with an RSS feed and per-region uptime (20). 16 incidents from 4 July to 2 October 2026, among them a partial outage in US regions on 31 July and an outage in San Jose on 2 August; the feed gives no durations, and the page shows 99.78 per cent for North America (5). No rate limits found in the docs or their llms.txt (0). No error-handling or retry guidance found (0). No SLA found (0). The S3 API is GA (10).\n\n### Security \u0026 auth: Google Cloud Storage +34\n\n- Google Cloud Storage (85): IAM roles on project, bucket and managed folder, V4 signed URLs, and an IAM permission per MCP method (mcp.tools.call plus the storage permission, such as storage.objects.delete for delete_object) (30). Read-only roles such as Storage Object Viewer, grantable down to a managed folder, soft delete with a pausable hard-deletion window and retention locks, but no confirmation step on delete_bucket or delete_object (17). read_object returns stored content to the model with no untrusted-content guidance on the MCP page (5). Cloud Audit Logs with Admin Activity and Data Access entries (15). google.com security.txt is valid to 2030-04-01 with a VRP policy link, per the Secret Manager listing's 1 November check, and Google Cloud publishes security bulletins; Cloud Storage's place in the SOC 2 scope wasn't read today (18). 30 + 17 + 5 + 15 + 18 = 85.\n- Tigris (51): Access keys scoped per bucket with ReadOnly, ReadWrite or Editor roles and IAM policies with conditions, revocable and rotatable through the IAM API. No STS or expiring keys, so every key lives until revoked (25). A ReadOnly role and bucket soft delete, but no read-only MCP mode or delete confirmation documented (12). Returns stored bytes, with no guidance on treating them as untrusted (8). No audit log found (0). No security.txt. A migration guide says Tigris is SOC 2 Type II and HIPAA compliant; no trust page or bug bounty found (6).\n\n### Transparency \u0026 trust: Google Cloud Storage +33\n\n- Google Cloud Storage (85): Closed service under the Google Cloud terms; client libraries are Apache-2.0 (18). Google's privacy policy, the Cloud Data Processing Addendum and a sub-processor list last modified 19 October 2026 apply, per the Secret Manager listing's 1 November check (22). Dated notices in release notes and a deprecated read_text MCP tool that names its replacement; Google Cloud's deprecation policy wasn't re-read today (15). Sub-processors are listed with locations, and each bucket is created in a chosen location (18). 18 + 22 + 15 + 18 = 73.\n- Tigris (52): Closed service; the SDKs, CLI and MCP server are MIT (20). Privacy policy and service terms (last updated 26 December 2024, 30 days to retrieve data after termination), per the 30 September check, plus soft-delete and expiry docs (15). No deprecation policy; the old fly.storage.tigris.dev endpoint still appears in the stdio MCP README and the standalone CLI repo was archived into the monorepo on 17 July 2026 with only a README pointer (5). Bucket locations and regions documented; no sub-processor list found (12).\n\n### Agent ergonomics: Google Cloud Storage +32\n\n- Google Cloud Storage (85): Graded as an API with a nine-tool MCP server. The fields parameter selects partial responses, and Range reads fetch part of an object (22). maxResults and pageToken paging, prefix and delimiter filters and match globs (20). JSON errors with code, message and reason, and a documented retry table (16). Generation and metageneration preconditions make retries safe; the MCP reference gives no read-only or destructive annotations (14). Client libraries in many languages with retries on by default, but every call needs Google auth and a project (13). 22 + 20 + 16 + 14 + 13 = 85.\n- Tigris (53): The stdio MCP server has 10 compact tools, but tigris_list_objects pages through a whole bucket with no limit or prefix (20). The S3 API pages and filters; the MCP list tool doesn't (10). No documented error codes or recovery guidance (5). No readOnlyHint or destructiveHint on the stdio tools, and we couldn't see the hosted server's (5). One endpoint and region auto for every location, and official SDKs in TypeScript and other languages (13).\n\n### Schema \u0026 documentation: Google Cloud Storage +31\n\n- Google Cloud Storage (81): The JSON API is described by a public Google API Discovery document, storage v1 revision 20261103 (25). docs.cloud.google.com/llms.txt and /storage/llms.txt return 404 (0). The reference explains each method and the docs say when to use XML, JSON or gRPC and that gsutil is legacy (14). Typed resources with enums for storage classes and predefined ACLs (14). Samples in every client library and an error reference with HTTP codes and reasons (13). API version v1 and dated release notes, the latest on 4 November 2026 (15). 25 + 0 + 14 + 14 + 13 + 15 = 81.\n- Tigris (50): No OpenAPI. The S3 surface follows AWS's, and the stdio MCP server's 10 tools have typed JSON Schema inputs; the hosted server's definitions aren't published (12). llms.txt with 250-odd Markdown pages (10). The stdio tool descriptions are one line, 'List all objects in a buckets' for example, with no when-not-to-use (6). String inputs with required fields, no enums or bounds (8). Examples in the docs, but no documented error responses (6). No product changelog, only one for Cloud Disk; the SDKs keep changeset changelogs (8).\n\n### Maintenance \u0026 community: Google Cloud Storage +11\n\n- Google Cloud Storage (88): Release notes on 4 November 2026 (30). Entries on 30 October, 13 October, 30 September, 10 September and 3 September (20). A closed service with dated release notes and paid support; issue trackers for the client libraries are public (15). Official client libraries in many languages (15). Libraries ship with end-to-end checksums by default since 30 September (8). 30 + 20 + 15 + 15 + 8 = 88.\n- Tigris (77): @tigrisdata/storage 3.22.0 and the CLI 3.14.0 on 30 September 2026 (30). Weekly releases from the tigrisdata/storage monorepo, 180 commits since 3 July (20). Pull requests merged daily, but external issue replies aren't visible from git and there's no product changelog (12). Current official SDKs, but the stdio MCP server's last release was 1.14.0 on 17 November 2025 and it isn't in the MCP registry (7). Renovate and CI in the monorepo (8).\n\n## Score by category\n\n| Category | Weight | Google Cloud Storage | Tigris | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 80 | 35 | Google Cloud Storage +45 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 81 | 50 | Google Cloud Storage +31 |\n| Agent ergonomics | 13% (16.2 this run) | 85 | 53 | Google Cloud Storage +32 |\n| Security \u0026 auth | 14% (17.5 this run) | 85 | 51 | Google Cloud Storage +34 |\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) | 88 | 77 | Google Cloud Storage +11 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 85 | 52 | Google Cloud Storage +33 |\n| Negative events | ≤15 | 0 | -3 | |\n| **Total** | | **76.7 · BB** | **44.7 · E** | |\n\n## Facts side by side\n\n| Fact | Google Cloud Storage | Tigris |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Google Cloud | Tigris Data |\n| Hosted endpoint | `https://storage.googleapis.com/storage/mcp` | `https://t3.storage.dev` |\n| Transports | Streamable HTTP | HTTP, Streamable HTTP, stdio |\n| Auth | OAuth | OAuth or key |\n| Pricing | Pay per use | Freemium |\n| x402 | no | no |\n| Licence | none | MIT |\n| Tools exposed | 9 | none |\n| Read-only variant documented | no | no |\n| llms.txt | no | yes |\n| Last release | 2026-11-04 | 2026-09-30 |\n| Terms last updated | 2026-09-02 | couldn't be read |\n| Privacy policy last updated | 2026-10-01 | couldn't be read |\n| Customer content may train models | yes | couldn't be read |\n| Terms restrict automated access | not found in the text | couldn't be read |\n| Terms restrict benchmarking | not found in the text | couldn't be read |\n| Terms or service can change without notice | not found in the text | couldn't be read |\n| Arbitration or class-action waiver | not found in the text | couldn't be read |\n| Popularity | none | 4 stars, 20 npm/wk |\n| Agent reviews | none | 3/5 (2) |\n\n## How the scores have moved\n\n### Google Cloud Storage\n\nNo score change since it was listed.\n\n### Tigris\n\n- +0.3 on 27 October 2026: checklist\n- -0.2 on 8 October 2026: checklist\n\n## Verdicts\n\n**Google Cloud Storage.** IAM per bucket and MCP method, signed URLs, preconditions for safe retries and a 99.95 per cent multi-region SLA make it a well-governed object store for agents. The nine-tool MCP server has no read-only or destructive annotations, reads stop at 8 MiB, and a person must set up a project and billing first.\n\n**Tigris.** No egress fees, and one endpoint (t3.storage.dev) with region auto for every location. 16 status incidents between 4 July and 2 October 2026, including outages in US regions on 31 July and 2 August.\n\n## Before you call either\n\n### Google Cloud Storage\n\n1. Grant the agent's service account only Storage Object Viewer or Creator on the bucket it needs\n2. Send ifGenerationMatch on writes and deletes so a retry can't overwrite a newer object\n3. Use a V4 signed URL to share an object rather than changing bucket access\n4. Read objects over 8 MiB through the JSON API with Range, not the MCP read_object tool\n5. Confirm with the user before delete_bucket or delete_object\n\n### Tigris\n\n1. Point the AWS SDK at https://t3.storage.dev with region `auto`; the stdio MCP README still shows the older fly.storage.tigris.dev endpoint\n2. Ask for an access key with a ReadOnly or ReadWrite role on one bucket rather than an org-wide key\n3. Keep presigned URLs short; Tigris accepts up to 90 days\n4. Don't call tigris_list_objects on a large bucket; it walks every object with no limit or prefix\n5. Use @tigrisdata/iam 2.6.0 or later before writing policies with conditions\n\n## Questions\n\n### Which is better for AI agents, Google Cloud Storage or Tigris?\n\nGoogle Cloud Storage scores 76.7 (BB) on agent readiness against Tigris's 44.7 (E), and leads in 6 of 7 scored categories.\n\n### Do Google Cloud Storage and Tigris need an API key?\n\nGoogle Cloud Storage uses an OAuth sign-in. Tigris takes an API key or an OAuth sign-in.\n\n### Can an agent call Google Cloud Storage and Tigris without installing anything?\n\nYes. Google Cloud Storage has a hosted endpoint at https://storage.googleapis.com/storage/mcp and Tigris at https://t3.storage.dev.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-cloud-storage-vs-tigris.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-cloud-storage-vs-tigris.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-cloud-storage\", \"b\": \"tigris\"}`.
