## 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)

Scored 2026-11-05.

- **Supply Chain Security**: 12/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 28 of 28 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - Install-script risk not yet assessed.
  - 1 of 28 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 39/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Maintenance history not yet determined.
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 80/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1715 tokens (~41/item across 41 items; 41 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 41 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 42 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).

## Install

### How do I install the Steam (read-only) MCP server?

Steam (read-only) ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

## Common questions

### What is the Steam (read-only) MCP server?

Steam (read-only) is an MCP server listed in the public MCP registry as io.github.Sarg338/steam-mcp. Read-only Steam: friends, games, achievements, sales, plus game recommendations and co-op nights. This page covers its MCPB bundle (https://github.com/Sarg338/steam-mcp/releases/download/v1.19.0/steam-mcp.mcpb).

### Is the Steam (read-only) MCP server safe to use?

Steam (read-only) scores 55 out of 100 on VerifyMCP. 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 Steam (read-only) MCP server expose?

Steam (read-only) exposes 41 tools: steam_get_deck_compatibility, steam_resolve_vanity_url, steam_get_player_summary, steam_get_steam_level, steam_get_player_bans, and 36 more. Their descriptions and schemas cost roughly 1,662 tokens of context every time the server is loaded.

### What licence is the Steam (read-only) MCP server under?

Steam (read-only) declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
