## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (2)

### `kg_validate` (~175 tokens)

Judges a .kg.yaml graph (or .kg.json, with format json) against the current KG-SSOT contract without writing. Returns verdict PASS or FAIL and, per occurrence, code (stable), place, path, line, message and hint (the fix). Fix by the hints and judge again before writing.

Input parameters:

- `format`: the text format: yaml (.kg.yaml, the default) or json (.kg.json, in the contract's JSON profile); with name, the default comes from the extension
- `limit` (integer): occurrences returned (default 50)
- `name` (string): the name the graph would have in the store (verifies the external end as if it were there)
- `text` (string, required): the whole document: YAML in a .kg.yaml, JSON in a .kg.json

### `kg_schema_help` (~52 tokens)

The current contract for writing a graph that passes: the full MUST and SHOULD schemas, a minimal example that passes, the integrity rules and the fix for the most common codes. Call it before writing the first graph.

## Common questions

### What is the KG-SSOT MCP server?

KG-SSOT is an MCP server listed in the public MCP registry as io.github.marciocar/kg-ssot. Company-brain knowledge graphs: confirmed claims cite sources, and decisions get revisited. This page covers its PyPI package (kg-ssot).

### Is the KG-SSOT MCP server safe to use?

KG-SSOT scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the KG-SSOT MCP server expose?

KG-SSOT exposes 2 tools: kg_validate, kg_schema_help. Their descriptions and schemas cost roughly 227 tokens of context every time the server is loaded.

### Is the KG-SSOT MCP server still maintained?

KG-SSOT is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the KG-SSOT MCP server under?

KG-SSOT declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
