Cisco Umbrella

Cisco Umbrella MCP Service — a stateless HTTP MCP server wrapping the Cisco Umbrella REST API v2 (classic Umbrella, not the newer Secure Access/SASE product), scoped to the 10 endpoints MSPbots currently uses: DNS/proxy/firewall/AMP-retrospective activity reports, roaming computers, app-discovery (applications/protocols/application categories), managed-provider customer list, and the provider console summary.

Tech stack: Python 3.12 + uv + FastMCP (Starlette/Uvicorn)

Authentication method note

Cisco Umbrella's classic REST API supports the OAuth2 client_credentials grant — a pure server-to-server exchange, no user browser redirect. An admin creates an API Key + Key Secret pair in the Umbrella dashboard (Admin > API Keys), and this service exchanges that pair for a short-lived (1 hour) bearer token on every call (no refresh token, so no cross-request caching — same "re-login every call" pattern as covedataprotection-mcp/webroot-mcp/logmein-mcp).

POST https://api.umbrella.com/auth/v2/token
Authorization: Basic base64(apiKey:keySecret)
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials

Region note: MSPbots' own integration config for Cisco Umbrella has a dataCenter field (us/eu). Verified directly against the raw OpenAPI spec embedded in Cisco's own developer docs for all 10 endpoints plus the auth/token endpoint: every one of them lists exactly one host, https://api.umbrella.com — there is no separate EU host for classic Umbrella. (Cisco's newer "Secure Access" product does have its own region concept, but that's a different product from what this service targets.) This service therefore ignores the dataCenter value entirely; it's not needed for any of these 10 endpoints.

from_/to accept epoch milliseconds, ISO-8601, or a relative offset (e.g. "-1days", "-7days", "now"), per Umbrella's reporting API conventions. (from_ has a trailing underscore because from is a Python reserved word — it's mapped to the literal from query parameter internally.)

Known Gaps

Tested against two real Managed Provider (MSSP) accounts. Of the 10 tools, only 2 are confirmed working with verified real data; the other 8 are either blocked or unverified (empty results don't prove correctness — they just mean no error was raised).

✅ Confirmed working (real, non-empty, cross-validated data):

• cisco_umbrella_get_providers_console — real subscription summary on both test accounts (customerCount: 77 and customerCount: 47 respectively).
• cisco_umbrella_list_customers — returned 77 real customer organizations (real company names) on account 1. Failed with 403 Access Forbidden on account 2 — confirmed by decoding that account's token that it genuinely lacks the admin.customers:read scope (20 total scopes vs. 76 on account 1). Not a code bug; a real per-key permission difference.

⚠️ Unverified — returned well-formed but empty results on both accounts, not proven correct: cisco_umbrella_get_activity_dns, _proxy, _firewall, _amp_retrospective, cisco_umbrella_list_roaming_computers. Cross-checked the live OpenAPI parameter definitions for Activity DNS directly against Cisco's own docs (pulled the raw spec, not summarized) — from/to/limit are exactly as implemented, no missing/misnamed parameter. The likely explanation is that both test accounts are Managed Provider root orgs, which have no direct DNS/proxy/firewall/AMP traffic or roaming computers of their own — that data lives under each managed customer org individually. Searched Cisco's docs for a "query as this customer org" scoping parameter/header for classic Umbrella — found none (a "Multi-Org" token-scoping concept exists, but only for the separate Secure Access/SASE product, not classic Umbrella). There's a distinct "Providers" API family (/providers/customers/{customerId}/...) that looks like it might be the intended path to per-customer data, but it's outside the 10-endpoint scope confirmed for this build. Needs a real single-customer-org credential (not provider-level) to actually confirm these 5.

• cisco_umbrella_list_applications, _protocols, _application_categories (App Discovery) — confirmed blocked, not a code bug. Reproduced identically on both test accounts and via direct curl with the same tokens (ruling out request-construction issues): 403 Access Forbidden on account 1, 500/403 on account 2. Both tokens' scope lists included reports.appdiscovery:read, so this is most likely a package/entitlement restriction (App Discovery as a paid add-on not included in either account's "Umbrella for MSSPs" tier), not a permissions or parameter problem.
• cisco_umbrella_get_providers_console returns a single subscription-summary object, not a list — confirmed via both live tests. Despite the plural name in MSPbots' own configured API list ("Providers Consoles"), double-check this against whatever MSPbots' existing collector expects (array vs single object).
• The Applications app-discovery endpoint's optional parameter list may not be fully exhaustive (a couple of parameters near the end of that endpoint's schema were not fully captured during research) — the ones documented here (sources, identity, labels, controllable, categories, subcategory, limit, offset) are confirmed real; there may be one or two more not yet added.
• Scope is limited to the 10 operations MSPbots currently uses (user-confirmed), not Umbrella's full API surface (which also includes Networks, Internal Domains, Sites, Network Tunnels, Policies, Tagging, the separate "Providers" API for per-customer actions, and the Key Admin API for managing API keys themselves).
