mcp-hub

io.github.ni-c/mcp-hubv0.6.0Docker & Containers

Serve many stdio MCP servers from one container over HTTPS, with a built-in OAuth 2.1 login

In-path gate · all MCP tools

Using mcp-hub in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

uv tool install mcpindex-gate && mcpindex-config-wire

Trust verdict · v1 advisory · method

NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-08-14).

Contracts can change after screening, with no version bump. The gate pins mcp-hub’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Verdict API

curl -s mcpindex.ai/api/v1/trust/server/io-github-ni-c-mcp-hub

Free-tier verdict as JSON: decision + dimensions + severity. Call it from your agent before it invokes a tool it just discovered.

Details

version: v0.6.0
category: Docker & Containers
quality: 90 / 100
operator: ni-c

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 962,376). Verify it yourself.
