Why the edge:
- Maintenance & community, MCP Toolbox for Databases +60: MCP Toolbox for Databases 95 (v1.16.0 on 5 November 2026, one day before this check (30). Eight releases from v1.10.0 (27 August) to v1.16.0 in the 90 days (20). Pull requests merge daily and new tools land in each fortnightly release, though 432 issues and pull requests are open (20). io.github.googleapis/mcp-toolbox is in the official registry at 1.16.0 (15). Release automation, lint, tests and conformance workflows (10). 30 + 20 + 20 + 15 + 10 = 95.); Snowflake-managed MCP server 35 (Per the 9 October check, not re-read on 4 November (snowflake.com's site terms bar robots). The last dated change to the MCP server is the SSE note of 20 August 2026, 76 days before 4 November, and platform release notes ran to 9 October (20). Of the three dated MCP entries recorded (22 July, 7 August and 20 August 2026), two fall in the 90 days from 6 August, and newer entries couldn't be looked for (0, cause time). A public changelog and a support route through cases and the community, whose answers were not sampled (10). The managed server is not in the official MCP registry, which lists only the separate open-source `io.github.Snowflake-Labs/mcp` (0). Nothing to install. The REST API specification repository was last updated on 10 September 2026 (5). 20+0+10+0+5 = 35.)
- Agent ergonomics, MCP Toolbox for Databases +36: MCP Toolbox for Databases 82 (The PostgreSQL prebuilt set lists 29 tools (15), split into five toolsets a client can load one at a time, and write tools disappear in read-only mode (plus 8). Results are bounded per tool, some prebuilt tools take limits, and BigQuery tools compact empty schema fields (14). Errors come back as tool errors; paths are sanitised from file errors since 1.15.0 (12). readOnlyHint and destructiveHint are set per tool and switch with the source's read-only state (18). Prebuilt sets need only environment variables, and SDKs exist in Python, JavaScript, Go and Java (15). 23 + 14 + 12 + 18 + 15 = 82.); Snowflake-managed MCP server 46 (The tool list is whatever the operator declares, up to 50 a server, and Snowflake recommends one Cortex Agent tool per server with further servers for other uses (18). The search tool takes `columns` and `limit`. SQL and custom tool responses are cut at 250 KB with no paging, and agent tool responses carry every intermediate step and can pass 200 KB (8). Errors are documented as a symptom table, and `invalid_client` covers both wrong credentials and a network policy block (6). The SQL tool is read-only by default. No `readOnlyHint` or `destructiveHint` annotations and no idempotency support are documented (6). Few required arguments and standard MCP clients work with no SDK, but each client needs a hand-made OAuth integration and some clients can't choose a role (8). Per the 9 October check, not re-read on 4 November.)
- Reliability, MCP Toolbox for Databases +30: MCP Toolbox for Databases 80 (Scored as local software the owner runs. A Go binary, a container in Artifact Registry and @toolbox-sdk/server on npm, with install paths per platform (20). Tests, lint, conformance and nightly tier-report workflows in the repository; the pass state wasn't read (15). 432 open issues and pull requests on a repository with 16,818 stars and releases every two weeks, triaged with labels, though the backlog is large (15). Semantic versioning with a published policy, release-please CHANGELOG and an UPGRADING.md (15). 1.x since well before this check, v1.16.0 now (15). 20 + 15 + 15 + 15 + 15 = 80.); Snowflake-managed MCP server 50 (Graded as a hosted service. Snowflake's site terms (14 April 2025) bar robots, spiders and scrapers on snowflake.com, so the docs, the status page and www.snowflake.com were not re-read on 4 November and the 9 October readings stand. Statuspage at status.snowflake.com with components by cloud region, and no component for Cortex or the MCP server was recorded (15, the value for a vendor status page with no component for the product). Only the front page's 15 days to 9 October were read, with two incidents marked critical (one region for 68 minutes on 25 September 2026, other regions for 35 minutes on 27 September), one marked major (Snowsight connectivity, 6 October) and one minor (8 October). The rest of the window from 6 August is unread and gets no credit, so the incident line is held at the recorded 10. No rate limit for the MCP endpoint found (0). The REST API's OpenAPI files describe 429 and retry with backoff, but the MCP page gives no retry or idempotency guidance (5, partial value held). 99.9 per cent monthly SLA with service credits (10). Generally available since 4 November 2025 (10). 15+10+0+5+10+10 = 50.)
- Payments & pricing, MCP Toolbox for Databases +25: MCP Toolbox for Databases 60 (Free, self-hosted, nothing to buy, so 20 + 20 + 20. No payment protocol (0).); Snowflake-managed MCP server 35 (No x402, MPP or L402 (0). Per-credit prices by region and edition and per-unit AI rates are public in the Service Consumption Table of 2 October 2026, though the MCP server has no line of its own (20). A 30-day trial needs only an email address, and Cortex tools stay off until a card is added (15). A person signs up in a browser and an administrator creates the server and the OAuth integration (0). Per the 9 October check, not re-read on 4 November.)
- Schema & documentation, MCP Toolbox for Databases +24: MCP Toolbox for Databases 85 (Every tool's parameters are typed in tools.yaml and published as JSON Schema over MCP (25). mcp-toolbox.dev serves llms.txt (10). Prebuilt descriptions vary from one line ("Use this tool to execute a single SQL statement.") to detailed, and few say when not to use a tool (12). Typed parameters with required flags; execute_sql takes free SQL (12). Many examples, samples and codelabs; error responses are thinly documented (11). Semver, a dated CHANGELOG and versioned docs (15). 25 + 10 + 12 + 12 + 11 + 15 = 85.); Snowflake-managed MCP server 61 (No OpenAPI or published schema covers the MCP endpoint, and the snowflake-rest-api-specs repository has no MCP server file. Custom tools carry a JSON Schema the operator writes in `input_schema`, and built-in tools take fixed arguments shown only as examples. The schemas `tools/list` returns were not read (15). llms.txt and a Markdown copy of every docs page (10). Tool names and descriptions are written by the operator, and Snowflake's own examples are one line each, such as "cortex search service for all products" (8). Typed inputs for custom tools, with free-text SQL and a single `message` string for the analyst and agent tools (8). Request and response examples for two tool types, a troubleshooting table and OAuth failure modes, with no JSON-RPC error codes and an empty object as the search response example (8). Dated release notes, behaviour change notes and a stated protocol revision of 2025-11-25 (12). Per the 9 October check, not re-read on 4 November.)
- Transparency & trust, Snowflake-managed MCP server +20: MCP Toolbox for Databases 64 (Apache-2.0 (30). A self-hosted server; data goes only to the configured sources and to a telemetry exporter if one is set. There is no data-handling statement of its own (15). A versioning policy defining breaking changes, UPGRADING.md and a notice for the repository rename; prebuilt tool removals are listed in the changelog (16). Telemetry is off unless --telemetry-otlp or --telemetry-gcp is set, and the docs say so (16). 30 + 15 + 16 + 16 = 77.); Snowflake-managed MCP server 84 (Closed service with clear published terms, an acceptable use policy and a consumption table (15). A DPA and Security Addendum of 11 January 2026 with 72-hour incident notice and customer-chosen regions. The DPA says leftover data is deleted promptly after termination without a day count, and the Privacy Notice excludes Customer Data (22). A written behaviour change policy with an eight-week bundle period and dated notes, though the August 2026 MCP change shipped outside it (15). Four sub-processors and 28 affiliates listed with locations and 28 days' notice of additions. AI model providers are not named on the list (16). Per the 9 October check, not re-read on 4 November.)
