## 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**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 57/100
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 980 tokens (~122/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 8 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 current MCP spec version (2026-07-28).

## Install

### How do I install the Wikidata + Google Knowledge Graph MCP server?

Wikidata + Google Knowledge Graph MCP is a hosted endpoint at https://wikidata-knowledge-mcp.revanalex.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Wikidata + Google Knowledge Graph MCP is listed in the public MCP registry as com.dondego/wikidata-google-knowledge-mcp. Read-only Wikidata tools and identity evidence. Local optional Google KG; bounded public remote. This page covers its hosted endpoint (https://wikidata-knowledge-mcp.revanalex.workers.dev/mcp).

### Is the Wikidata + Google Knowledge Graph MCP server safe to use?

Wikidata + Google Knowledge Graph MCP scores 75 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 Wikidata + Google Knowledge Graph MCP server expose?

Wikidata + Google Knowledge Graph MCP exposes 8 tools: kg_search, kg_entity, kg_related, kg_resolve, kg_audit_identity, and 3 more. Their descriptions and schemas cost roughly 846 tokens of context every time the server is loaded.

### Does the Wikidata + Google Knowledge Graph MCP server require authentication?

No. We connected to Wikidata + Google Knowledge Graph MCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Wikidata + Google Knowledge Graph MCP server still maintained?

Wikidata + Google Knowledge Graph MCP 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.
