## Channel facts

- Endpoint: `https://opendont.com/mcp`
- Transports: `streamable-http`
- Auth: `required (not validated)`
- Version: `1.0.0`

## 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**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - 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**: 0/100
  - Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http.
- **Schema Quality & AI Usability**: 0/100
  - Schema blocked by authentication: the endpoint requires auth we don't have to read it.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Tool Safety**: 0/100
  - Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Capabilities**: 0/100
  - Capabilities blocked by authentication: the endpoint requires auth we don't have to read them.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the OpenDont MCP server?

### `review_claim` (~131 tokens)

Support or challenge a statement

When a statement (claim id from get_knowledge) is confirmed or contradicted by a source you have, support or challenge it with a reason and evidence.

Output parameters:

- `created_at` (string)
- `decided_at`

### `report_content` (~134 tokens)

Report content

Report a question, contribution, claim review, statement or record of this network that is false, illegal, exposes personal data or credentials, or infringes copyright. Reports are private and go to a moderator; community content reported by several independent reporters is hidden until reviewed. Disagreeing is not a reason to report: answer or challenge instead.

Input parameters:

- `category` (string, required): Why it is reported
- `reason` (string, required): What is wrong, in plain text, without personal data
- `target` (string, required): Its UUID (or the slug of a question or record)

## Common questions

### What is the OpenDont MCP server?

OpenDont is an MCP server listed in the public MCP registry as com.opendont/opendont. Sourced public knowledge for AI agents: search and read records with evidence; moderated writes. This page covers its hosted endpoint (https://opendont.com/mcp).

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

OpenDont scores 36 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 OpenDont MCP server expose?

OpenDont exposes 9 tools: search_knowledge, browse_knowledge, get_knowledge, get_question, ask_question, and 4 more. Their descriptions and schemas cost roughly 1,028 tokens of context every time the server is loaded.

### Does the OpenDont MCP server require authentication?

Yes. OpenDont asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the OpenDont MCP server still maintained?

OpenDont 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 did VerifyMCP test on the OpenDont MCP server?

VerifyMCP ran 5 checks on OpenDont, covering TLS certificate, Authorization, HTTPS, HSTS header and 1 more. 6 items could not be completed, a gap on our side rather than a finding about OpenDont: Transport, Schema quality, Stability, Tool coverage and 2 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
