## 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)

## MCP tools (6)

### `create_decision` (~161 tokens)

Rank named options against weighted criteria and return the winner, full ranking, per-criterion breakdowns, methodology, weights used, and a plain-language explanation. Main tool. method defaults to weighted_sum (also weighted_product, topsis). 100% deterministic.

Input parameters:

- `criteria` (array, required): Weighted criteria. Each: {name, weight (relative, >=0), direction: 'benefit' (higher better, default) | 'cost' (lower better)}.
- `method` (string)
- `options` (array, required): Named alternatives. Strings or {name, scores} objects.
- `scores` (object, required): Score matrix. {"Option A": {"Criterion 1": 8, ...}, ...} or array form or inline on options.

### `score_options` (~135 tokens)

Score options against criteria when the score matrix is supplied separately. Returns the full normalized scored matrix + ranking, without the narrative winner explanation.

Input parameters:

- `criteria` (array, required): Weighted criteria. Each: {name, weight (relative, >=0), direction: 'benefit' (higher better, default) | 'cost' (lower better)}.
- `method` (string)
- `options` (array, required): Named alternatives. Strings or {name, scores} objects.
- `scores` (object, required): Score matrix. {"Option A": {"Criterion 1": 8, ...}, ...} or array form or inline on options.

### `sensitivity_analysis` (~182 tokens)

Test how robust the winner is to criteria-weight changes. Sweeps each weight +/- 'variation' (default 0.2) over 'steps' (default 10), recomputes the ranking, and reports a robustness score, the criteria most likely to flip the result, and flip points.

Input parameters:

- `criteria` (array, required): Weighted criteria. Each: {name, weight (relative, >=0), direction: 'benefit' (higher better, default) | 'cost' (lower better)}.
- `method` (string)
- `options` (array, required): Named alternatives. Strings or {name, scores} objects.
- `scores` (object, required): Score matrix. {"Option A": {"Criterion 1": 8, ...}, ...} or array form or inline on options.
- `steps` (integer)
- `variation` (number)

### `compare_two` (~176 tokens)

Head-to-head comparison of exactly two options. Returns the winner, score margin, how many criteria each option wins, and a per-criterion breakdown. Pass option_a/option_b (names) or a 2-element options array, plus criteria and scores.

Input parameters:

- `criteria` (array, required): Weighted criteria. Each: {name, weight (relative, >=0), direction: 'benefit' (higher better, default) | 'cost' (lower better)}.
- `method` (string)
- `option_a` (string)
- `option_b` (string)
- `options` (array): Named alternatives. Strings or {name, scores} objects.
- `scores` (object, required): Score matrix. {"Option A": {"Criterion 1": 8, ...}, ...} or array form or inline on options.

### `list_methods` (~34 tokens)

List scoring methods (weighted_sum, weighted_product, topsis) with normalization details, score ranges, and when to use each.

### `health_check` (~16 tokens)

Server health, version, and capabilities.

io.github.inity13/decisionmatrix-mcp is listed in the public MCP registry as io.github.inity13/decisionmatrix-mcp. Deterministic multi-criteria decision analysis for AI agents, score, rank & explain options. This page covers its npm package (decisionmatrix-mcp).

### Is the io.github.inity13/decisionmatrix-mcp server safe to use?

io.github.inity13/decisionmatrix-mcp scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 22 September 2026. It declares no install or post-install scripts. 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 io.github.inity13/decisionmatrix-mcp server expose?

io.github.inity13/decisionmatrix-mcp exposes 6 tools: create_decision, score_options, sensitivity_analysis, compare_two, list_methods, health_check. Their descriptions and schemas cost roughly 704 tokens of context every time the server is loaded.

### Is the io.github.inity13/decisionmatrix-mcp server still maintained?

io.github.inity13/decisionmatrix-mcp is still listed as active in the MCP registry. We last reached this channel on 22 September 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 io.github.inity13/decisionmatrix-mcp server under?

io.github.inity13/decisionmatrix-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
