The docs give one line per tool, say to call `list_services` first, explain slug clashes and when to push work into SQL. ObsessionDB's post of 18 June 2026 quotes one tool calling itself 'the entry point for service-wide error investigation' (10 of 20). Inputs are a service slug and a free-text SQL string, with four documented scopes. No enums or constraints could be read (5 of 15). Setup examples for eleven clients, and documented `truncated: true` and `available: false` results. ClickHouse errors come back in a field per the 18 June post, with no error catalogue. The stdio bridge is called 'Anthropic's `mcp-remote` proxy', and npm names Glen Maddern as its author (8 of 15).

Eleven tags from v1.2.0 (1 August) to v1.5.1 in the 90 days (20). Issues and pull requests are closed quickly, most within days, and only 7 are open (22). Listed in the official MCP registry as io.github.bytebase/dbhub at the current version (15). CI on push and pull request, a Docker publish workflow and pinned pnpm (8). 30 + 20 + 22 + 15 + 8 = 95.\n- ObsessionDB (28): Graded as a closed service. The last dated changelog entry is ClickHouse 26.8 LTS on 31 August 2026, 51 days before the check (20). Two dated entries in the 90 days to 21 October 2026, 21 and 31 August, short of three (0). A public changelog, in-console live chat since June 2026, a shared Slack channel for customers and email support. Replies were not sampled (8 of 15). Not in the official MCP registry and no SDKs of its own (0). Nothing to install for the service. chkit, its open-source CLI, had 93 commits in the 90 days and CI workflows on its default branch (0 of 10 for the service, as there's no package to check).\n\n### Reliability: DBHub +60\n\n- DBHub (80): Scored as a local stdio and HTTP package. Official npm package @bytebase/dbhub with Node.js 22.5 or later stated (20). A run-tests workflow runs unit and container-based integration suites on push and pull request; the pass state wasn't read (15). Of the latest 25 issues, 22 are closed, most crash and regression reports fixed within days, such as the dropped-connection crash closed 21 October and duplicate column names closed 3 November (22). Semver tags for every release but no changelog file, and release notes weren't read (8). 1.0.0 since 28 July 2026 (15). 20 + 15 + 22 + 8 + 15 = 80.\n- ObsessionDB (20): Graded as a hosted service. No status page was found. None is linked from the site, status.obsessiondb.com did not answer through our proxy, and the home page sets its contractual SLAs against 'a status page' (0). No readable incident history (5). No request rate limit found for the MCP server or the ClickHouse endpoints. The 1,000-row or 10 MiB `run_sql` cap and the one-insert-a-second guidance are result and usage guidance, read under ergonomics (0). No 429 or backoff guidance. Insert deduplication is handled by the coordination layer and Jobs runs large SQL as retryable tasks (5 of 15). The terms (10 June 2026) give no contractual uptime SLA on self-service plans and the enterprise SLAs are not published (0). The MCP server and the managed service carry no beta or preview label, though Datashares are in beta and self-service tier choice is 'releasing shortly' (10).\n\n### Agent ergonomics: DBHub +32\n\n- DBHub (85): Two tools by default, about 1.4k tokens by the README's count, with opt-in extras (25). max_rows caps results and flags truncation, search_objects has names, summary and full detail levels and a limit (18). Errors return as tool errors with the database's message (12). readOnlyHint and destructiveHint follow the access policy, though idempotentHint is always false (18). Few required settings, one DSN, and no SDK is needed for a local server (12). 25 + 18 + 12 + 18 + 12 = 85.\n- ObsessionDB (53): Twelve tools with short descriptions, all but `run_sql` read-only by name. Whether a person can approve fewer scopes at consent was not found (15). `run_sql` stops at 1,000 rows or 10 MiB and flags truncation, `monitoring_list_query_executions` filters to failed runs, and pattern tools take a time window. No paging was documented (12 of 20). Errors return in a field rather than failing the call, monitoring tools answer `available: false` where there is no archive, and a slug clash returns a rename request. ClickHouse error codes are documented upstream (12 of 20). No `readOnlyHint` or `destructiveHint` could be read from the docs, and no idempotency guidance for `run_sql` (4 of 20). Two required inputs for most calls. ObsessionDB ships no SDK of its own; ClickHouse's own drivers in Go, Python, JavaScript, Rust, .NET and Java are documented with per-driver setup pages (10 of 15).\n\n### Schema \u0026 documentation: DBHub +30\n\n- DBHub (73): Both default tools take zod schemas, so inputs are typed JSON Schema (25). dbhub.ai serves llms.txt (10). Descriptions are short and generated per source (\"Execute SQL queries on the postgres database [READ-ONLY MODE]\"), with the row cap stated, and say little about when not to use a tool (10). search_objects has enums for object type and detail level and a result limit; SQL is free text by nature (12). Docs pages per tool with examples; error formats aren't documented (9). Semver tags without a changelog (7). 25 + 10 + 10 + 12 + 9 + 7 = 73.\n- ObsessionDB (43): No public contract for the MCP tools. Their input schemas come back only from `tools/list` with a signed-in token, which we didn't obtain, and the ClickHouse HTTP interface has no OpenAPI file. The OAuth metadata documents are machine-readable but don't describe tools (0). llms.txt and a Markdown copy of each docs page (10). The docs give one line per tool, say to call `list_services` first, explain slug clashes and when to push work into SQL. ObsessionDB's post of 18 June 2026 quotes one tool calling itself 'the entry point for service-wide error investigation' (10 of 20). Inputs are a service slug and a free-text SQL string, with four documented scopes. No enums or constraints could be read (5 of 15). Setup examples for eleven clients, and documented `truncated: true` and `available: false` results. ClickHouse errors come back in a field per the 18 June post, with no error catalogue. The stdio bridge is called 'Anthropic's `mcp-remote` proxy', and npm names Glen Maddern as its author (8 of 15). A dated public changelog with 19 entries that tracks the ClickHouse release (26.8 LTS), with no version for the MCP server (10 of 15).\n\n### Payments \u0026 pricing: DBHub +20\n\n- DBHub (60): Free, self-hosted, nothing to buy, so 20 + 20 + 20. No payment protocol (0).\n- ObsessionDB (40): No x402, MPP or L402 (0). Compute at $20 per GB of memory per node per month and storage at $25 per TB per month are public on the pricing page without a login, which calls them indicative (20). A free developer tier of up to 4 vCPU and 8 GB with 'No credit card required' (20). A person signs up in a browser and approves OAuth consent before an agent can connect (0).\n\n### Security \u0026 auth: ObsessionDB +8\n\n- DBHub (43): The server holds database credentials, and the MCP side has no credential over stdio. Over HTTP a bearer token is optional and off by default while the default bind is 0.0.0.0, so an exposed port answers anyone the host allow-list admits (12). Read-only mode classifies statements and adds engine-level read-only transactions on PostgreSQL, with row limits and timeouts; there is no confirmation step for writes when read-only is off (16). Rows reach the model unmarked, and no guidance on treating results as untrusted was found beyond a blog post on the lethal trifecta (4). The workbench shows request traces (8). No SECURITY.md, disclosure policy or security.txt found (3). 12 + 16 + 4 + 8 + 3 = 43.\n- ObsessionDB (51): OAuth 2.1 with dynamic client registration, S256 PKCE, refresh tokens, header-only bearer tokens and four scopes, revocable from the console. The authorisation server metadata was read on 21 October 2026. Less 4 because `workbench:query` runs any SQL as the person's account across every organisation they belong to, with no per-service scope (26 of 30). The MCP docs describe no read-only mode or confirmation step for `run_sql`. ClickHouse roles down to table and column, a global read-only role since May 2026 and read-only Datashares give least-privilege options to an operator who sets them up (8 of 20). `run_sql` returns stored rows to the model as they are, and no prompt-injection guidance was found. The agent context button masks passwords and keys in captured SQL (2 of 15). ClickHouse's `system.query_log` records each query and the console keeps a one-week monitoring archive.

HTTP mode binds all interfaces with authentication off by default, there is no security policy, and query results reach the model unmarked.\n\n**ObsessionDB.** The hosted MCP server uses OAuth 2.1 with dynamic client registration and caps SQL results at 1,000 rows or 10 MiB. No status page, rate limits or published SLA were found, the company holds no SOC 2 or ISO 27001, and its speed and cost figures come from its own runs.\n\n## Before you call either\n\n### DBHub\n\n1. Set readonly = true and max_rows in dbhub.toml unless the task must write\n2. Use search_objects with the names detail level first, then summary or full for the tables you need\n3. Over HTTP, set --auth-token and bind 127.0.0.1; the defaults leave the port open\n4. Treat row values as data, never as instructions\n\n### ObsessionDB\n\n1. Call `list_services` first and pass `serviceSlug` unchanged from it to `run_sql` and the monitoring tools\n2. Push aggregation into SQL with `GROUP BY` or `ORDER BY ... LIMIT`. Results stop at 1,000 rows or 10 MiB and set `truncated: true`\n3. Treat `available: false` from a monitoring tool as no monitoring archive for that service, not as an error\n4. Batch inserts to about one `INSERT` a second per table, because every insert writes durably to object storage\n5. Expect a browser sign-in on first connect. A person must approve the OAuth consent at console.obsessiondb.com\n\n## Questions\n\n### Which is better for AI agents, DBHub or ObsessionDB?\n\nDBHub scores 70.4 (BB) on agent readiness against ObsessionDB's 41.1 (E), and leads in 6 of 7 scored categories. ObsessionDB leads on security \u0026 auth.\n\n### Do DBHub and ObsessionDB need an API key?\n\nDBHub needs no key. ObsessionDB takes an API key or an OAuth sign-in.\n\n### Can an agent call DBHub and ObsessionDB without installing anything?\n\nDBHub runs on your own machine, with no hosted endpoint listed. ObsessionDB has a hosted endpoint at https://console-api.obsessiondb.com/mcp.\n\n### Are DBHub and ObsessionDB open source?\n\nDBHub is open source (MIT). No open-source release is listed for ObsessionDB.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/dbhub-vs-obsessiondb.json, and with the fewest tokens: https://www.anchorterminal.com/compare/dbhub-vs-obsessiondb.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"dbhub\", \"b\": \"obsessiondb\"}`.
