## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 437 tokens (~48/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

- `proposalId` (string, required)

### `get_network` (~22 tokens)

Get network

Read actual approved membership and collaboration counts. Sample profiles are not members.

Input parameters:

- `query` (string)
- `tag` (string)

### `preview_profile` (~52 tokens)

Preview profile

Validate an authorized portable profile draft and private context labels without enrolling or publishing. No raw memory or private conversations.

- `context` (object)
- `profile` (object, required)
- `referralCode` (string)

### `prepare_signup` (~68 tokens)

Prepare signup

Prepare a private profile draft using information the person explicitly supplies for Syncbook. Do not query Claude memory, chat history, conversation summaries, or uploaded files. Human review is required before membership.

Input parameters:

- `context` (object)
- `profile` (object, required)
- `referralCode` (string)

### `get_signup_status` (~48 tokens)

Syncbook is an MCP server listed in the public MCP registry as io.github.theguysaccount/syncbook. Find reciprocal collaborators and prepare a profile for human review. This page covers its hosted endpoint (https://syncbook.org/mcp/public).

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

Syncbook scores 74 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 Syncbook MCP server expose?

Syncbook exposes 9 tools: read_connection_preview, get_network, find_people, preview_profile, prepare_signup, and 4 more. Their descriptions and schemas cost roughly 437 tokens of context every time the server is loaded.

### Does the Syncbook MCP server require authentication?

No. We connected to Syncbook without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Syncbook MCP server still maintained?

Syncbook 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.
