Category Databases
How this component scores in each security and reliability category. 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. How we score → Why this is hard to score →
Supply Chain Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 30 of 95 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency5
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 335 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 499 tokens (~166/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "oracle_query" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
oracle_describe_table Oracle Describe Table ~168
Return detailed metadata for a table: table comment; columns with data type, length, precision/scale, nullability, default value, and column comment; primary key columns; unique constraints; foreign keys with referenced owner/table/columns; and indexes with uniqueness and columns. With owner provided, queries ALL_* views (may require privileges); otherwise uses USER_* views. Optional url supports per-call connection. table_name and owner are typically uppercase.
| Name | Type | Req | Description |
|---|---|---|---|
| owner | string | – | Schema/owner of the table. Uses ALL_* views when provided; otherwise USER_*. |
| table_name | string | yes | Target table name. Typically uppercase; quoted mixed-case identifiers require exact case. |
| url | string | – | Per-call connection string. Format: oracle://user:password@host:port/service |
| Name | Type | Req | Description |
|---|---|---|---|
| columns | array | yes | – |
| comment | – | yes | – |

| uniqueConstraints | array | yes | – |
No examples provided.
oracle_list_tables Oracle List Tables ~139
List table names for the current user or the specified schema owner. Without owner, queries USER_TABLES; with owner, queries ALL_TABLES and may require appropriate privileges. Optional url enables per-call connection (oracle://user:password@host:port/service). The owner value is treated case-insensitively but typically uppercase is used. Returns the total count and the table name list.
| Name | Type | Req | Description |
|---|---|---|---|
| owner | string | – | Schema/owner name. Without owner uses USER_TABLES; with owner uses ALL_TABLES (requires privileges). |
| url | string | – | Per-call connection string. Format: oracle://user:password@host:port/service |
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | yes | – |
| message | string | yes | – |
| success | boolean | yes | – |
| tables | array | yes | – |
No examples provided.
oracle_query Oracle SELECT Query ~192
Execute a read-only SELECT/WITH query on Oracle. Rejects non-SELECT statements and enforces a row limit by appending FETCH FIRST when needed. Use max_rows to cap returned rows; when url includes maxRows, it overrides max_rows. Optional url supports per-call connection in the form oracle://user:password@host:port/service?privilege=SYSDBA&maxRows=N. Returns rows as an array of objects keyed by column names. Intended strictly for data retrieval.
| Name | Type | Req | Description |
|---|---|---|---|
| max_rows | integer | – | Maximum rows to return. Enforced by appending FETCH FIRST when needed. |
| sql | string | yes | SQL text of a read-only query. Must start with SELECT or WITH; DML/DDL are rejected. |
