## 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 2026-11-04.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - 1 of 35 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to cloudwise-app/cloudcostwise).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 0 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 391 tokens (~97/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 70/100
  - Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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 (4)

### `scan` (~134 tokens)

Scan the user's AWS account for waste with their local credentials (read-only; any non-read AWS call is refused). Takes 30-60 s per region; up to 4 regions run at once. COST: the RI/Savings Plans checks call Cost Explorer, billed by AWS at $0.01 per request (a few cents a scan); tell the user before running, and pass include_cost_explorer=false to skip them. regions: comma-separated, or 'all'; default us-east-1 plus the profile's region.

Input parameters:

- `include_cost_explorer` (boolean)
- `profile`
- `regions`

Output parameters:

- `result` (string)

### `list_findings` (~49 tokens)

List findings from the last scan, with ids, optionally filtered by waste type or a minimum monthly saving in USD.

Input parameters:

- `min_monthly_savings` (number)
- `waste_type`

Output parameters:

- `result` (string)

### `explain_finding` (~49 tokens)

Explain one finding: what was detected, the threshold, the pricing used, why it is waste, the risk of acting, and how validated this check is.

Input parameters:

- `finding_id` (string, required)

Output parameters:

- `result` (string)

### `fix_guidance` (~48 tokens)

How to fix one finding: the recommended action and, where known, the AWS CLI command, as text for the user to review. Never executes anything.

Input parameters:

- `finding_id` (string, required)

Output parameters:

- `result` (string)

## Common questions

### What is the cloudcostwise MCP server?

cloudcostwise is an MCP server listed in the public MCP registry as io.github.cloudwise-app/cloudcostwise. Find AWS waste with your own read-only credentials. Runs locally. Nothing is sent unless you opt in. This page covers its PyPI package (cloudcostwise).

### Is the cloudcostwise MCP server safe to use?

cloudcostwise scores 88 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 cloudcostwise MCP server expose?

cloudcostwise exposes 4 tools: scan, list_findings, explain_finding, fix_guidance. Their descriptions and schemas cost roughly 280 tokens of context every time the server is loaded.

### Is the cloudcostwise MCP server still maintained?

cloudcostwise 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 cloudcostwise MCP server under?

cloudcostwise 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.
