# Fidensa

Connects AI assistants to an independent certification registry to evaluate tool trust scores, verify code integrity hashes, and find vetted extensions.

## What it does

This server links coding agents directly to the Fidensa evaluation catalog over MCP. When an agent plans to call an unfamiliar skill, sub-agent, hook, or MCP server, it can inspect official verification grades beforehand. It helps prevent running compromised tools.

Four operations function without registration: status checks (`check_certification`), catalog queries (`search_capabilities`), hash matching (`verify_file`), and submitting outcome logs (`report_experience`). However, side-by-side evaluations with `compare_capabilities`, cryptographic inspection of `.cert.json` signatures, and full contract downloads require a free `FIDENSA_API_KEY`. Without this token, multi-tool comparisons remain unavailable.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `FIDENSA_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

            }
        }
    }
}
```

## When to use it
- verify trust ratings of external tools before execution
- validate local file checksums against certified records
- discover certified alternatives to unvetted utilities
- compare trust metrics between two similar tools
- submit execution telemetry reports to update reliability records

## Example prompts
- Inspect the trust tier of `mcp-server-filesystem` using `check_certification` before running it.
- Find verified SQLite utilities by querying `search_capabilities`.
- Run `compare_capabilities` to benchmark trust scores between `mcp-server-sqlite` and `mcp-server-better-sqlite3`.
