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. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (diagram_delete). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability59
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1818 tokens (~202/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage94
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 80% of tool parameters carry a description.Partial
- Structured output schemas are declared (33% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
diagram_create Save a diagram ~174
Saves a new diagram from a DSP scene or Mermaid text; returns its id, revision 1, content hash and chain hash. key is your stable name for it, unique in the workspace: your repeat with the same key and content returns the existing diagram, not a copy. brief stores context for the next agent. Versions are kept until you delete the diagram or its workspace is deleted.

diagram_edit Change a diagram ~229
Changes a saved diagram as a new revision; old ones stay. Give baseRevision (the revision you last read), a one-line message, and ops (typed operations, https://zindex.ai/schemas/ops.schema.json), mermaid (the whole diagram edited from view mermaid; only differences apply), restoreRevision (an earlier version back), or brief. An edit with an error saves nothing; one that changes nothing returns noop. requestId makes a retry return the first result. A conflict lists what changed.

diagram_get Read a diagram ~217
Reads a diagram by id or key.

Another workspace's diagram answers NOT_FOUND.

How do I install the Zindex MCP server?
Zindex is a hosted endpoint at https://api.zindex.ai/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.

What is the Zindex MCP server?
Zindex is an MCP server listed in the public MCP registry as ai.zindex/zindex. Immutable agent diagrams: create, edit, validate and render versioned diagrams over MCP. This page covers its hosted endpoint (https://api.zindex.ai/mcp).
Is the Zindex MCP server safe to use?
Zindex scores 63 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 Zindex MCP server expose?
Zindex exposes 9 tools: diagram_find, diagram_get, diagram_validate, diagram_create, diagram_edit, and 4 more. Their descriptions and schemas cost roughly 1,364 tokens of context every time the server is loaded.
Does the Zindex MCP server require authentication?
No. We connected to Zindex without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Zindex MCP server still maintained?
Zindex is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
