Report server version and configuration status (lightweight).

Call this at session start (or after a tool-call timeout) to confirm the MCP is up, see which version is running, and verify the device inventory config loads. Lightweight: it only reads and parses config.ini — it does NOT open any eAPI/pyeapi connection to EOS devices, so it is safe to call against a large fleet without touching the network.

Always returns the same keys: status (healthy / degraded / error), service, version, config_path (resolved config.ini path), device_count (EOS hosts in config), tags (sorted distinct tags), and config (ok / error / missing). On a degraded or error result, detail carries the reason.

List EOS devices registered in config, optionally filtered by tags.

Return structured device facts: hostname, model, serial, EOS version, uptime, memory.

Return device facts (model, serial, EOS version, uptime) for multiple devices in parallel.

Return EOS version string for a device (quick connectivity check).

Show config diff on an EOS device.

rollback_id=1 (default) → diff vs most recent rollback checkpoint. rollback_id=N → diff vs Nth rollback checkpoint. Note: diff vs startup-config requires EOS 4.30+; older versions fall back gracefully.

List configure sessions and their state on an EOS device.

Shows pending, pendingCommitTimer, and completed sessions. Useful for tracking in-flight push_config operations.

Run a single enable-mode command on an EOS device and return text output.

Run multiple enable-mode commands on one EOS device and return labelled output.

Run an enable-mode command on multiple EOS devices in parallel.

Specify targets via 'hostnames', 'tags', or both.

Run multiple enable-mode commands on multiple EOS devices in parallel.

Specify targets via 'hostnames', 'tags', or both. Each device's output is labelled by hostname and command.

Retrieve the running-config from an EOS device.

Push configuration to an EOS device via a named configure session.

When dry_run=True (default) shows diffs and aborts — no changes applied. When dry_run=False commits with a rollback timer (default 300 seconds). Call confirm_config_session before the timer expires to finalize.

Confirm (finalize) a pending configure session commit timer on an EOS device.

Abort a pending configure session on an EOS device.

Collect show tech-support from an EOS device (large output, 30+ seconds).

Run health checks on EOS devices and return a Markdown daily brief.

Checks environment (temperature, cooling, fans, PSUs), errdisabled interfaces, device uptime, MLAG status, and recent syslog alerts (BGP/OSPF/STP/LACP/MLAG/ link-down) within the last 'since_hours' hours. Returns CRITICAL/WARNING/OK per device with a summary. Specify targets via 'hostnames', 'tags', or both (default: all configured devices).
