Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-08-03. - **Supply Chain Security**: 0/100 - Malware scan not yet available for this package. - CVE data not yet available for this package. - Install-script risk not yet assessed. - Dependency-health data not yet available. - **Provenance & Transparency**: 32/100 - Source repository is publicly reachable at the declared URL. - Provenance check failed: no build-provenance attestation is published. - License check failed: no license is declared. - Actively maintained (last published 108 days ago). - Disclosure check failed: no security disclosure policy was found in the source repository. - **Schema Quality & AI Usability**: 49/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 746 tokens (~373/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 27/100 - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 67/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 0% of tool parameters carry a description. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. **Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm. ## Install ### Claude ```bash claude mcp add optisol-business-db-metadata-extractor-mcp -- docker run --rm -i docker.io/optisolbusinesssol/db-metadata-extractor-mcp:0.1.6 ``` ### Codex ```bash codex mcp add optisol-business-db-metadata-extractor-mcp -- docker run --rm -i docker.io/optisolbusinesssol/db-metadata-extractor-mcp:0.1.6 ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "optisol-business-db-metadata-extractor-mcp": { "type": "local", "command": [ "docker", "run", "--rm", "-i", "docker.io/optisolbusinesssol/db-metadata-extractor-mcp:0.1.6" ], "enabled": true } } } ``` ### Hermes ```yaml mcp_servers: optisol-business-db-metadata-extractor-mcp: command: "docker" args: ["run", "--rm", "-i", "docker.io/optisolbusinesssol/db-metadata-extractor-mcp:0.1.6"] ``` ### Other ```json { "mcpServers": { "optisol-business-db-metadata-extractor-mcp": { "command": "docker", "args": [ "run", "--rm", "-i", "docker.io/optisolbusinesssol/db-metadata-extractor-mcp:0.1.6" ] } } } ``` ## Changelog Every change recorded for this component, newest first.

Returns a lightweight summary (never the full JSON). The output_path MUST be an absolute directory path where the JSON file will be written. If the directory does not exist it will be created. Args: db_type: Database type — one of: 'postgres', 'snowflake', 'sqlserver', 'bigquery', 'oracle' output_path: Absolute directory path to save the extracted JSON. Example: /Users/you/project/outputs or C:\Users\you\project\outputs database_name: Database / catalog name host: Hostname or IP (postgres, sqlserver, oracle) port: Port number (postgres=5432, sqlserver=1433, oracle=1521) username: Login username password: Login password schema_name: Schema to extract (postgres default 'public', sqlserver default 'dbo') tables: Optional list of table names to limit extraction account: Snowflake account identifier warehouse: Snowflake warehouse name role_name: Snowflake role name project_id: BigQuery GCP project ID service_account_key: BigQuery service-account JSON key (as string) Example — PostgreSQL: { "db_type": "postgres", "output_path": "/home/user/metadata_output", "host": "10.0.0.5", "port": 5432, "username": "admin", "password": "secret", "database_name": "mydb", "schema_name": "public" } Example — Oracle: { "db_type": "oracle", "output_path": "C:\\metadata_output", "host": "20.168.23.183", "port": 152… Input parameters: - `account` (string) - `database_name` (string) - `db_type` (string, required) - `host` (string) - `output_path` (string, required) - `password` (string) - `port` (integer) - `project_id` (string) - `role_name` (string) - `schema_name` (string) - `service_account_key` (string) - `tables` - `username` (string) - `warehouse` (string) ### `query_metadata` (~139 tokens) Query a previously-saved metadata JSON file on disk without loading everything into context. Args: filepath: Absolute path to the JSON file saved by extract_metadata table_name: Filter by table name (substring match, optional) field_name: Filter by column/field name (substring match, optional) page: Page number (default 1) page_size: Records per page (default 20) Input parameters: - `field_name` (string) - `filepath` (string, required) - `page` (integer) - `page_size` (integer) - `table_name` (string) ## Diagnostics Captured diagnostic sections: Provenance.
