# Changelog

This project uses [CalVer](https://calver.org/) — version numbers
encode the date the package was tested against the upstream Cisco APIs
and published. Format: `YYYY.MM.DD` with optional `.N` post-release
suffix for same-day fixes.

## 2026.04.27 — initial public release

First public release on PyPI as `mcaxl`. Renamed from the internal
working name `mcp-cucm-axl` to fit the operator's `mc<interface>`
naming convention.

### Tools (19 total)

**Foundational**: `axl_version`, `axl_sql`, `axl_list_tables`,
`axl_describe_table`, `cache_stats`, `cache_clear`, `health`.

**Route plan**: `route_partitions`, `route_calling_search_spaces`,
`route_patterns`, `route_inspect_pattern`, `route_lists_and_groups`,
`route_translation_chain`, `route_digit_discard_instructions`,
`route_device_pool_route_groups`, `route_devices_using_css`,
`route_filters`.

**Real-time registration (RisPort70)**: `device_registration_status`,
`device_registration_summary`.

### Prompts (10 total)

Schema-grounded conversation seeds: `route_plan_overview`,
`investigate_pattern`, `audit_routing`, `cucm_sql_help`,
`sip_trunk_report`, `phone_inventory_report`, `user_audit`,
`inbound_did_audit`, `hunt_pilot_audit`, `whoami`.

### Engineering rigor

- **Read-only by structural guarantee**: no AXL write methods are
  registered; the SQL validator rejects non-SELECT/WITH queries as
  defense-in-depth.
- **Hamilton-style review closed**: 7 findings (2 Critical, 3 Major,
  2 Minor) addressed during pre-release hardening, each with a
  regression test.
- **Live-cluster verified**: every tool path verified against a
  live CUCM 15 cluster before release.
- **155 unit tests**, schema drift guard for all 71 known
  `fkcallingsearchspace_*` columns (via
  `test_complete_schema_coverage_against_known_columns`).

### Known limitations

- `route_translation_chain` evaluates CUCM wildcards (`X`, `!`,
  `[0-9]`, `@`, `\\+`) but does not model route-filter constraints on
  `@` patterns — use as guidance, not authoritative.
- AXL WSDL must be supplied externally (Cisco-licensed; not bundled).
  See `README.md` for bootstrap instructions.
- RisPort `state_info` cursor pagination is implemented but not yet
  stress-tested on clusters with > 1000 devices in a single class.

### Acknowledgments

Borrowed two ideas from
[`@calltelemetry/cisco-cucm-mcp`](https://github.com/calltelemetry/cisco-cucm-mcp)
(MIT licensed): the RisPort70 SOAP envelope shape and the
exponential-backoff retry policy on HTTP 503. Their tool covers
operational debugging (logs, perfmon, packet capture) — install both
side-by-side for compound questions like *"audit found CSS X
unreferenced AND RisPort confirms zero phones registered against it."*
