At a Glance & Executive Verdict
Influxdb3 MCP Server
Databases · Local stdio
Quality: 82/100 (Excellent) | Auth: API Key required
Microsoft SQL Server
Databases · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Influxdb3 MCP Server if you need specialized Databases tools running via a local process. Choose Microsoft SQL Server if your workspace requires Databases integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Influxdb3 MCP Server when:
You need dedicated capabilities in the Databases domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: INFLUX_MCP_TOOL_PROFILE.
Influxdb3 MCP Server is categorized under Databases and uses a local stdio subprocess. In contrast, Microsoft SQL Server belongs to Databases using local stdio subprocess. Select Influxdb3 MCP Server when you need capabilities focused on databases and Microsoft SQL Server when you require tools for databases.

list_profiles
List configured connection profiles. Call first when picking a non-default profile. Returns `name`, `description` and `allow_write` per profile.
get_object
Get metadata for one relation (columns, indexes, constraints, relationships) or routine (definition). `name` accepts `Users`, `dbo.Users` or `[dbo].[Users]`. `includes` omitted → `columns`. Relations also carry an approximate `row_count`.
run_query
Execute read-only T-SQL SELECT; only SELECT allowed (no DML/DDL). Returns results as CSV in the `data` field (inline) or a snapshot resource URI when `snapshot=true`. Inline limit: 500 rows (hard ceiling 1000). Snapshot limit: 10 000 rows (hard ceiling 50 000). Prefer `analyze_query` for plan tunin…
analyze_query
Analyze execution plan for a read-only SELECT. Returns compact JSON summary (cost, operators, cardinality, warnings, `missing_indexes`, waits, stats); no result rows, full XML at `plan_uri`.
run_command
Execute write T-SQL (DDL/DML). Advertised only when some profile sets `AllowWrite=true` (off by default); still rejected at call time when the target `profile` is locked. Caller manages transactions. Returns `rows_affected` (−1 for DDL) and server `messages`. Marked destructive; intended for human-…
