## Connection (mcpServers)

```json
{
  "mcpServers": {
    "upgradelens": {

```


## Trust

- hygiene: 80
- liveness: 28
- freshness: 100
- provenance: 45
- drivers: +website -unreachable(1 failures) +updated-6d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 100/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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: 100 (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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,164 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: 4, about 1,164 tokens to load them all
- tool set hash: 93627b64eeab6b9b8f9f7bc2c80dd54c
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.mattpicone/upgradelens.svg)](https://protogrid.dev/servers/io.github.mattpicone/upgradelens)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `check_dependency_upgrade`: Use when a coding agent needs a cited go/no-go risk decision without steps before changing an existing npm or PyPI dependency between two exact versions. Returns action_allowed, vulnerability delta, compatibility, EOL, and breaking-change evidence. Use plan_dependency_upgrade instead for ordered migration work. Do not use to choose a target, install a new package, search general docs, or analyze another ecosystem. Read-only and safe to retry.
- `find_safe_upgrade_target`: Use only when an existing npm or PyPI dependency has an exact current version but no chosen target. Ranks candidates; candidates are not declared safe and require check_dependency_upgrade or plan_dependency_upgrade. Do not use when a target is stated, for a new install, or as authorization to edit files. Read-only and safe to retry.
- `plan_dependency_upgrade`: Use when a coding agent needs a migration checklist, refactor actions, ordered review actions, changelog links, or test steps for exact current and target npm/PyPI versions. Use check_dependency_upgrade instead for a go/no-go without steps. Do not use to choose a target, install a package, or provide a general tutorial. Read-only and safe to retry.
- `review_dependency_upgrade`: Use when an agent reviews a Dependabot, Renovate, npm, or PyPI version change before merge. One cited result combines security delta, runtime compatibility, breaking changes, go/no-go risk, and ordered migration actions for exact current and target versions. Do not use for new installs, unknown versions, general documentation, or other ecosystems. Read-only and safe to retry.
