## Connection (mcpServers)

```json
{
  "mcpServers": {
    "estatetrace-mcp": {
      "type": "sse",
      "url": "https://api.estatetrace.ai/mcp/sse"

## Trust

- hygiene: 100
- liveness: 28
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo -unreachable(1 failures) ~updated-46d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 70/100 (needs work)

### protocol: 50 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- warn `protocol.transport`: only the legacy HTTP+SSE transport, deprecated until 2027-07-28
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: estatetrace_a2a_inventory (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); estatetrace_a2a_settle (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); estatetrace_a2a_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 626 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`: 1 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: 5, about 626 tokens to load them all
- tool set hash: 2f161471ec4be3ee3f48cf990941c89b
- tools last changed: 2026-10-08T22:58:42.531Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.palunallc/estatetrace-mcp.svg)](https://protogrid.dev/servers/io.github.palunallc/estatetrace-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
