## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__devops-status__devops_check_certs` `mcp__devops-status__devops_check_dns` `mcp__devops-status__devops_get_incidents` `mcp__devops-status__devops_status_check` `mcp__devops-status__devops_watch_stack` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `devops_watch_stack`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Check the health of a named vendor stack — a saved list of vendors representing your infrastructure dependencies. On the first call, provide vendors to define the stack; subsequent calls can omit vendors to reuse the saved list. Stacks are saved per authenticated caller, or per local server process; a shared deployment that does not authenticate callers saves nothing, so there vendors is required on every call and the response says so. Up to 20 vendors are saved per stack and checked per call; use several stack names for a larger set. Returns a unified health snapshot with an aggregate rollup plus per-vendor detail. A vendor that cannot be resolved or reached is reported in its own row and left out of the saved stack, so one bad entry never discards the sweep. Every vendor with an active problem gets a pre-filled devops_suggest_action call in nextToolSuggestions. Ideal for morning status checks or pre-deploy sweeps. Multiple stacks can coexist (e.g., "production", "staging").
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `devops_check_certs`

- The description's first verb is "inspect": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Inspect SSL/TLS certificate health for one or more domains by performing a real TLS handshake. Works for any internet-accessible domain — no vendor registry required. Reports days to expiry (flagged at < 30 days warning and < 7 days critical), certificate subject and SANs, issuer, hostname coverage, chain-trust verification, TLS protocol version negotiated (flags TLS 1.0/1.1 as insecure — a server offering only those is still inspected), cipher suite, and HSTS presence when the port answers HTTP. The handshake completes even for a certificate clients would reject, so a broken certificate is reported rather than hidden behind a connection error: a hostname mismatch surfaces in cert.hostname_verification_error and a chain-trust failure (self-signed, untrusted root) in cert.authorization_error, both status "critical". Non-HTTP TLS ports (IMAPS 993, SMTPS 465, DNS over TLS 853) are graded the same way, with HSTS reported as not checked. If a domain fails to connect at all, check devops_check_dns first — the name may not resolve. When a certificate fails to issue or renew, run devops_check_dns with record_types ["CAA"] to see which certificate authorities the domain allows.
```

### `devops_check_dns`

- The description's first verb is "resolve": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Resolve DNS records for one or more domains across multiple public resolvers and compare what each resolver returned. Works for any domain — no vendor registry required. Reports records found (A/AAAA/CNAME/MX/TXT/NS/CAA/SOA), resolution latency per resolver, and a typed outcome per resolver and record type so "the domain does not exist" (nxdomain), "the resolver could not answer" (servfail), and "no record of this type" (nodata) stay distinguishable. Resolver disagreements are reported without asserting a cause: partial_resolution (some resolvers answered, others returned nothing) points at a real propagation or resolver problem, while value_variation (every resolver answered with different values) is the normal steady state for anycast and geo-steered domains. Pair with devops_check_certs when a domain resolves but TLS to it is failing.
```

### `devops_get_incidents`

- The name "devops_get_incidents" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Fetch incident history and scheduled maintenance windows for a vendor. Returns full incident timeline — each investigator update, affected components, and resolution. Filter by status to focus on active incidents (use before deploy), resolved history (for postmortem), or upcoming maintenance windows, and narrow further with match (words in the title or affected component names) and since/until (a start-date range) — all applied before paging, so totals count only what they keep. Page through long histories with limit + offset — a truncated result discloses the total and returns the value to page with in nextOffset. Each response is held to 64,000 bytes per surface: a page can stop short of limit at that budget (the paging fields and notice say so), and an incident too large on its own keeps only its newest updates, with updates_omitted counting the rest — full_updates: true returns them all. Some vendor feeds cap their own history: when upstreamCeiling is present the vendor API returned everything it will serve, and older incidents are not reachable at a higher offset. On Atlassian Statuspage vendors, since (a date) also reads the status page's quarterly history archive back to that date, or 24 months back at most, where the page publishes one — not on a vendor that covers only part of a shared page, such as "sendgrid"; those records are marked source: "history" and carry the title, impact, start and end times, and final update message only. An empty result, or a history read that stopped short of since, explains itself in notice.
```

### `devops_list_vendors`

- The name "devops_list_vendors" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List vendors in the built-in registry, optionally filtered by category or name search. Returns slug, display name, category, and status page URL for each entry. Use to discover the correct slug to pass to other tools, or to see which vendors are available before configuring a stack.
```

### `devops_status_check`

- The name "devops_status_check" says "status": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Check the current health status for one or more vendors. Accepts registered vendor slugs (e.g., "github", "aws", "gcp", "gitlab") or raw Atlassian Statuspage base URLs. Registry entries are served by each vendor's native status API (Statuspage, Status.io, Slack, AWS Health, Google Cloud Service Health, Azure status, Azure DevOps status, Firehydrant) and normalized to one shape. Returns per-vendor operational indicator (none = all clear, minor, major, critical, maintenance = scheduled window), degraded components, and active incidents. Use mode: "detailed" for component lists and maintenance windows, narrowed with component_filter and bounded by component_limit. Batch-friendly — pass a list to check your full stack in one call; up to 20 vendors are checked per call, and any past the 20th come back in deferred_vendors to resend. A vendor that cannot be resolved or reached is reported in its own result row, so one bad entry never discards the rest. Every vendor with an active problem gets a pre-filled devops_suggest_action call in nextToolSuggestions.
```

### `devops_suggest_action`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return an incident-response playbook tailored to a vendor degradation, with pre-filled follow-up tool calls. Synthesizes category-specific guidance (cloud, CDN, dev-platform, auth, etc.) from built-in incident knowledge and the provided context. Use after devops_status_check or devops_get_incidents surfaces a problem to determine what to investigate next.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `devops-status`:

```json
{
  "permissions": {
    "allow": [
      "mcp__devops-status__devops_list_vendors",
      "mcp__devops-status__devops_status_check",

      "mcp__devops-status__devops_suggest_action"
    ],
    "ask": [
      "mcp__devops-status__devops_watch_stack"
    ],
    "deny": []
  }
}
```
