Why the edge:
- Reliability, MCP Toolbox for Databases +50: 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.); ReqRes MCP server 30 (status.reqres.in wasn't reachable (0). No history (5). Free-plan limits published with numbers (250 requests a day, 3 collections, 100 records) (15). No retry guidance (0). No SLA found (0). Not labelled beta (10). 0 + 5 + 15 + 0 + 0 + 10 = 30.)
- Maintenance & community, MCP Toolbox for Databases +45: 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.); ReqRes MCP server 50 (Registry entry in.reqres/reqres updated 16 October 2026 (30). No dated releases found (0). Blog and docs; no changelog (5 of 15). Official registry entry under its own namespace (15). No package to read (0). 30 + 0 + 5 + 15 + 0 = 50. 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.)
- Security & auth, MCP Toolbox for Databases +42: MCP Toolbox for Databases 75 (Source credentials stay in Toolbox, Google sources use IAM, and optional MCP authorisation validates OAuth 2.1 JWTs with required scopes. --allowed-origins and --allowed-hosts default to *, which the CLI docs themselves call unsafe even on localhost, though the default bind is 127.0.0.1 (20). Read-only mode is enforced at the engine, write tools are suppressed, and custom tools can fix SQL and bind parameters to the signed-in user (18). The security docs cover prompt injection and screening through Model Armor (12). OpenTelemetry traces and metrics per call when exported (10). Google's vulnerability intake with a stated response time and GitHub advisories (15). 20 + 18 + 12 + 10 + 15 = 75.); ReqRes MCP server 33 (No credential to start, and project keys returned by the tool (15 of 30). Writes on the agent's own project only (12 of 20). Every successful result ends with a sponsored message, labelled and 'never written as an instruction', which still puts third-party text in the model's context (3 of 15). No audit log (0). No security programme found (3 of 20). 15 + 12 + 3 + 0 + 3 = 33.)
- 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.); ReqRes MCP server 61 (Seven tools read from tools/list with JSON Schema inputs (25). llms.txt (10). A tool table says what each does (12 of 20). Records and fields are free-form objects (5 of 15). Worked flow on the MCP page, no error docs (6 of 15). Registry 1.0.0, no changelog (3 of 15). 25 + 10 + 12 + 5 + 6 + 3 = 61.)
- Transparency & trust, MCP Toolbox for Databases +17: 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.); ReqRes MCP server 47 (Closed service under readable terms; operating company not named in the parts read (10 of 30). You own your data, unclaimed agent projects are deleted after 72 hours, and the terms say the free service can end with reasonable notice (22 of 30). That notice clause and the 72-hour rule are dated commitments (10 of 20). Subprocessors not found (5 of 20). 10 + 22 + 10 + 5 = 47.)
- Payments & pricing, MCP Toolbox for Databases +10: MCP Toolbox for Databases 60 (Free, self-hosted, nothing to buy, so 20 + 20 + 20. No payment protocol (0).); ReqRes MCP server 50 (No machine payment protocol (0). Plan prices public (10). Free plan (20). An agent creates a project with no person (20). 0 + 10 + 20 + 20 = 50.)
