entrascope

Observability and diagnostics for Microsoft Entra ID and Azure Monitor, helping engineers troubleshoot authentication and authorisation failures.

Entra directory operations do not appear in the Azure subscription activity log. They are recorded in the Entra audit logs, under the category ApplicationManagement. entrascope reads them through Microsoft Graph and through Azure Monitor.

What it does

• Discovery. Enumerate application registrations and enterprise applications of every type, and project sign in audience, redirect URIs, requested and granted permissions, owners, credentials and their expiry, federated identity credentials, SAML configuration and the assignment requirement.
• Log interrogation. Read Entra audit logs, interactive and non interactive user sign ins, service principal and managed identity sign ins, Microsoft Graph activity and provisioning logs.
• Capability detection. Report when the logging you need is not enabled, which licence tier it requires and how to switch it on.
• Error explanation. Map AADSTS and Microsoft Graph error codes to meaning, likely cause and remediation.

Three surfaces, one core

Installation

pip install entrascope

From a clone, for development:

python3.14 -m venv .venv && .venv/bin/pip install -e ".[dev]"

Authentication

The quickest route needs nothing but an Azure CLI session:

az login
entrascope doctor --auth azure-cli

For unattended use, place client credentials at ~/.entra/provisioner-credentials.json with the keys ClientID, Secret and TenantID. The file must be mode 0600 inside a directory of mode 0700, and entrascope refuses to run otherwise.

Using it

Run entrascope with no arguments and it tells you what it can do. Every group and every command carries its own help and worked examples, so --help is always the next step.

Terminology, used the same way throughout

Diagnosing a failure

Start wide, then narrow. investigate gathers credentials, directory changes and sign in failures, applies a set of rules and ranks what it finds worst first, with the remediation for each.

entrascope doctor                          # can entrascope see what it needs
entrascope investigate                     # what is wrong in this tenant
entrascope investigate --severity error    # only what is already broken
entrascope investigate my-api              # narrow to one application
entrascope investigate my-api --full       # and show the evidence behind it

The argument to investigate is an application id, an object id or part of a display name, whichever the error message gave you. The same value works as --app on every other command. Findings are ranked error for something already broken, warning for something that will break, and note for the context that explains a result.

Looking at one thing at a time

entrascope discover applications --expiring          # credentials about to expire
entrascope discover applications --type single-page-application
entrascope discover enterprise-apps --type managed-identity
entrascope discover applications --app my-api --output json

entrascope logs audit --failures-only                # failed directory changes
entrascope logs audit --app my-api
entrascope logs signins --kind service-principal --failures-only
entrascope logs signins --app my-api --hours 6
entrascope logs graph-activity --workspace <workspace-id>
entrascope logs kinds                                # which sign in kinds exist

entrascope errors explain AADSTS7000215
entrascope errors explain "AADSTS50011: The redirect URI does not match"
entrascope errors search consent
entrascope errors list

discover apps and discover sps still work as short forms.

Reading the same data two ways

Audit events and sign ins can be answered by Microsoft Graph or by Azure Monitor, and both return the same fields.

entrascope logs audit --route graph                        # any tenant
entrascope logs audit --route monitor --workspace <id>     # longer retention

The Graph route needs only the right permission. The Monitor route needs a diagnostic setting and the Log Analytics Reader role, and gives longer retention. Microsoft Graph activity exists only through Azure Monitor. Sign in logs of any kind need an Entra ID P1 or P2 licence; audit logs do not.

Output and identity

--output json and --output yaml work on every command and are quiet, so the output can be piped straight into another tool. --auth chooses the identity: file, env, azure-cli or default. errors explain, errors list and errors search need no credentials at all, because the mapping is configuration.

As an MCP server

entrascope serve stdio

Register it with an assistant that speaks the Model Context Protocol. stdio has no OAuth, so credentials come from the environment or the credential file exactly as they do for every other command, and the server runs with your privileges. Every tool reads. None of them changes the directory.

The tool surface mirrors the commands: doctor, discover_applications, discover_service_principals, audit_events, sign_ins, graph_activity, explain_error, list_error_codes and sign_in_kinds. A tool result and the corresponding --output json payload are the same bytes, which a test enforces.

As a remote server

entrascope serve http --host 0.0.0.0 --port 8000

An OAuth 2.1 protected resource validating Entra issued bearer tokens. Terminate TLS at a reverse proxy and set ENTRASCOPE_BASE_URL to the canonical https URI, which appears in the protected resource metadata and which clients bind their tokens to. Set ENTRASCOPE_TENANT_ID and ENTRASCOPE_CLIENT_ID for the application registration this server presents.

The audience must equal the application id URI, a token issued for anything else is refused, and the caller's token is never forwarded to Microsoft Graph: Graph is called with the server's own credentials, because the data is tenant scoped rather than caller scoped.

A container image is built from the Dockerfile, running as a non root user on python:3.14-slim.

Corporate networks

entrascope honours a forward web proxy from HTTPS_PROXY, HTTP_PROXY, ALL_PROXY and NO_PROXY, and verifies TLS against a private certificate authority named in ENTRASCOPE_CA_BUNDLE, REQUESTS_CA_BUNDLE, SSL_CERT_FILE, CURL_CA_BUNDLE or the SSL_CERT_DIR directory. The same trust reaches the token endpoint and Azure Monitor. Run entrascope doctor to see exactly which proxy and which certificate authority are in force.

Documentation

Steering documents live in docs/steering: product, technology stack, repository structure, coding standards, configuration, credentials and security, Graph and Monitor, MCP server, testing strategy, release and publishing and the phased task plan.

Contributing

One change is one pull request, and every check must pass before it merges. The gate is ruff check, ruff format --check, mypy --strict src and pytest, plus five structural guards: no endpoint or table name written into code, no class without a framework contract comment, no secret in any output, one HTTP stack, one logger.

python3.14 -m venv .venv
.venv/bin/pip install -e ".[dev]"
.venv/bin/ruff check src/ tests/ && .venv/bin/mypy --strict src && .venv/bin/pytest

The rules the code follows, and why, are in docs/steering. Read coding-standards.md first.
