## 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**: 93/100
  - No malware found by supply-chain analysis.
  - Known CVEs were checked across the 4 of 5 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Dependency health was assessed across the 4 of 5 dependencies we could resolve, so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 4 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 79/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 206 tokens (~103/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 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).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (2)

### `contacts_find_duplicates` (~149 tokens)

Find duplicate contacts

Finds rows in a contact or customer CSV that are probably the same person, using emails, phone numbers, names and companies. Use to clean a CRM export, mailing list or customer list. Read-only, and never uses the network. Results include names from the file, so they reach the model. Report review pairs to the user instead of deciding them.

Input parameters:

- `columns` (object): Column names by field (email, phone, name, first, last, company, city), when detection fails
- `limit` (null|integer): Most groups and review pairs to return, default 100. 0 returns only the counts
- `path` (string, required): Path to the contact CSV file

Output parameters:

- `contacts` (integer)
- `extra_rows` (integer)
- `group_count` (integer)
- `groups` (null|array)
- `review` (null|array)
- `review_count` (integer)
- `skipped_rows` (null|array)
- `truncated` (boolean)
- `warnings` (null|array)

### `contacts_inspect_csv` (~57 tokens)

Inspect a contact CSV

Shows which columns samecontact detects in a CSV and how many rows it can read, without returning row contents. Use if the file is unfamiliar or a search found nothing.

Input parameters:

- `path` (string, required): Path to the contact CSV file

Output parameters:

- `columns` (object)
- `contacts` (integer)
- `header_row` (integer)
- `skipped_rows` (integer)

## Common questions

### What is the io.github.GillMacedo/samecontact MCP server?

io.github.GillMacedo/samecontact is an MCP server listed in the public MCP registry as io.github.GillMacedo/samecontact. Find duplicate customers and contacts in CSV exports. Your data stays on your machine. This page covers its npm package (samecontact).

### Is the io.github.GillMacedo/samecontact MCP server safe to use?

io.github.GillMacedo/samecontact scores 70 out of 100 on VerifyMCP. 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.GillMacedo/samecontact MCP server expose?

io.github.GillMacedo/samecontact exposes 2 tools: contacts_find_duplicates, contacts_inspect_csv. Their descriptions and schemas cost roughly 206 tokens of context every time the server is loaded.

### Is the io.github.GillMacedo/samecontact MCP server still maintained?

io.github.GillMacedo/samecontact is still listed as active in the MCP registry. We last reached this channel on 5 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 io.github.GillMacedo/samecontact MCP server under?

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

### What did VerifyMCP test on the io.github.GillMacedo/samecontact MCP server?

VerifyMCP ran 15 checks on io.github.GillMacedo/samecontact, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about io.github.GillMacedo/samecontact: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
