## Connection (mcpServers)

```json
{
  "mcpServers": {
    "registry-mcp": {
      "type": "http",
      "url": "https://ads.getlulu.dev/registry/mcp"
    }
  }

```


## Trust

- hygiene: 80
- liveness: 100
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% ~updated-61d-ago -duplicate-repo(8 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_mcps (destructiveHint, idempotentHint, openWorldHint); get_mcp (destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 295 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 2, about 295 tokens to load them all
- tool set hash: 418234e64986353a453b78d6869766e4
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Lulu-The-Narwhal/registry-mcp.svg)](https://protogrid.dev/servers/io.github.Lulu-The-Narwhal/registry-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `get_mcp`: Full details for one MCP server from the unified index, by slug
(as returned by search_mcps): description, per-client install commands
(Claude Code / Claude.ai / JSON config), transports, categories, the
registries it's listed on with links, and its trust score. Use after
search_mcps when the user wants to install or inspect a specific
server.
- `search_mcps`: Search every major MCP registry at once — the official registry,
Glama, PulseMCP and Smithery, deduplicated and ranked by a cross-
registry trust score. Use whenever you need to FIND an MCP server for
a capability: "find me a weather MCP", "is there an MCP for Stripe?",
"MCP servers for browsing the web". Returns ranked servers with
install one-liners and links. `category` narrows (e.g. "security",
"data"); `limit` caps results (1-10, default 8).
