mcaxl/README.md
Ryan Malloy ca6956e826 Rename to mcaxl + scrub for public PyPI release
Renames the package from `mcp-cucm-axl` to `mcaxl` to fit the
operator's mc<interface> naming convention (mcusb, mcaxl, …),
and scrubs Bingham-specific defaults so the package works for
anyone, anywhere.

Rename:
  - pyproject.toml: name, scripts entry point, description
  - src/mcp_cucm_axl/ → src/mcaxl/ (git mv preserves history)
  - All Python imports updated via sed
  - Cache directory: ~/.cache/mcp-cucm-axl/ → ~/.cache/mcaxl/
  - Log prefix [mcp-cucm-axl] → [mcaxl]
  - Package version lookup: importlib.metadata.version("mcaxl")
  - .mcp.json command updated to invoke `mcaxl` script
  - All 155 tests pass under the new name (verified)

Bingham-specific scrubs:
  - docs_loader._DEFAULT_INDEX_DIR: hardcoded /home/rpm/bingham/...
    path removed; defaults to None. Operators set CISCO_DOCS_INDEX_PATH
    env var; without it, prompts gracefully degrade with a fallback
    notice instructing the LLM to use the cisco-docs MCP search_docs
    tool instead.
  - prompts/_common.docs_or_empty_msg: removed the explicit
    /home/rpm/bingham/... path from the fallback message text.
  - server.py: removed dead-code copy of _docs_or_empty_msg() that
    was leftover from before the prompts package extraction.
  - README.md: completely rewritten as a public-facing readme. Lead
    paragraph names CUCM as the target platform, install instructions
    cover uvx / pip / Claude Code MCP add. Recommends cisco-cucm-mcp
    as the operations counterpart.

PyPI metadata:

# mcaxl
Read-only MCP server for **Cisco Unified Communications Manager (CUCM)**
exposes the AXL SOAP API and RisPort70 real-time registration state to
LLMs for dial-plan analysis, configuration auditing, and impact analysis.
> Tested against CUCM 15.0.1.12900. Should work on any CUCM 12.5+.
## Why this exists
CUCM's admin UI is great for one-config-at-a-time work but painful for
audit / discovery questions like:
- *"Which translation patterns rewrite the calling party number, and why?"*
- *"Which CSSs include the `Internal-PT` partition, in what order?"*
- *"Show me every route pattern targeting our PSTN carrier."*
- *"Are there partitions defined but unreachable from any CSS?"*
- *"Which phones are configured but not currently registered?"*
`mcaxl` gives an LLM SQL access to CUCM's Informix data dictionary,
schema-aware joins for common audit questions, and RisPort70
cross-reference for live registration state. Then a set of curated
prompts orchestrates the tools toward audit *findings*, not just data.
## Read-only by structural guarantee
The server **never registers** AXL write methods. There is no
`executeSQLUpdate`, no `add*` / `update*` / `remove*` / `apply*` /
`reset*` / `restart*` tool. Read-only is enforced by *absence* of write
operations, not by runtime sanitization. Defense-in-depth: SQL queries
are also client-side validated to begin with `SELECT` or `WITH`.
For operations that require write access (service control, packet capture,
log download, perfmon, etc.), install
[`@calltelemetry/cisco-cucm-mcp`](https://github.com/calltelemetry/cisco-cucm-mcp)
alongside this server. The two are complementary — `mcaxl` answers
"what does the config say?", `cisco-cucm-mcp` answers "what's happening
right now?".
## Install
```bash
# Run directly from PyPI:
uvx mcaxl
# Or as a pinned dev install:
pip install mcaxl
# Or via Claude Code's MCP registry:
claude mcp add cucm-axl -- uvx mcaxl
```
## Configure
Set these env vars (most operators use a `.env` file in the working directory):
```env
AXL_URL=https://your-cucm-pub:8443/axl/
AXL_USER=your-axl-service-account
AXL_PASS=your-password
# Optional:
AXL_VERIFY_TLS=false # CUCM ships self-signed certs; default off
AXL_CACHE_TTL=3600 # response cache TTL in seconds; 0 disables
AXL_RATE_LIMIT_RETRIES=3 # 502/503/504 retry count with backoff
AXL_WSDL_PATH= # explicit WSDL location override
AXL_WSDL_ZIP= # explicit toolkit zip path
CISCO_DOCS_INDEX_PATH= # for prompt enrichment (see Prompts section)
```
The AXL service account needs the **`Standard AXL Read Only API Access`**
role at minimum. It does *not* need the full `Standard AXL API Access`
role (read-write) — `mcaxl` is structurally incapable of using write
permissions even if granted.
## AXL WSDL bootstrap
CUCM's AXL toolkit is Cisco-licensed and not redistributable, so it's
not bundled. Download from your CUCM admin UI:
> Application → Plugins → Find → "Cisco AXL Toolkit" → Download
Drop the resulting `axlsqltoolkit.zip` into your working directory. On
first launch, the server auto-extracts `schema/15.0/` (or whichever
version matches your cluster) into `~/.cache/mcaxl/wsdl/15.0/`.
Alternative resolution paths (in order):
```bash
export AXL_WSDL_ZIP=/path/to/axlsqltoolkit.zip # explicit zip
export AXL_WSDL_PATH=/path/to/schema/15.0/AXLAPI.wsdl # explicit WSDL
# Or pre-populate the cache:
mkdir -p ~/.cache/mcaxl/wsdl/15.0/
cp /path/to/schema/15.0/* ~/.cache/mcaxl/wsdl/15.0/
```

### Route plan
| Tool | Purpose |
|---|---|
| `route_partitions()` | All partitions with pattern + CSS-member counts |
| `route_calling_search_spaces(name=None)` | CSS list with ordered partitions |
| `route_patterns(kind=None, partition=None, filter=None)` | Route Plan Report — patterns + transformations |

## Prompts (10 total)
Each prompt orchestrates multiple tool calls toward a specific
audit narrative. They appear in Claude Code's slash menu under
`/mcp__cucm-axl__<name>`:
- `route_plan_overview` — fresh audit conversation seed
- `investigate_pattern(pattern, partition=None)` — single-pattern deep dive
- `audit_routing(focus="full")` — comprehensive walkthrough with checklist
- `cucm_sql_help(question)` — catch-all SQL helper
- `sip_trunk_report(name_filter=None)` — SIP trunk inventory + findings
- `phone_inventory_report(filter=None)` — phone fleet aggregates with anomaly findings (cross-references RisPort)
- `user_audit(focus="full")` — end users + app users + role assignments
- `inbound_did_audit()` — XFORM-Inbound-DNIS inventory + screening pipeline
- `hunt_pilot_audit()` — hunt pilots, queue settings, line group membership
- `whoami(userid=None)` — single-user role chain (defaults to AXL service account)
### Optional: schema-grounded prompt enrichment
Set `CISCO_DOCS_INDEX_PATH` to a directory containing `chunks.jsonl`
and `index_meta.json` (produced by the
[`mcp-cisco-docs`](https://github.com/...) indexer or any compatible
embedding pipeline) to have prompts pull relevant Cisco documentation
chunks inline. Without this, prompts gracefully degrade to a fallback
notice instructing the LLM to use the sibling cisco-docs server's
`search_docs` tool.
## Cache
Responses are cached in SQLite at
`~/.cache/mcaxl/responses/axl_responses.sqlite`. The cache is
**cluster-isolated** by SHA-256 of `AXL_URL` — pointing the server
at a different cluster never serves stale data from a previous one.
Cache survives restarts. Clear with `cache_clear()` after a known
config change.
## Caveats
- `route_translation_chain` evaluates CUCM wildcards (`X`, `!`, `[0-9]`,
`@`, `\+`) but does *not* model route-filter constraints on `@`
patterns. Use as guidance, not authoritative.
- The package's `recordingprofile` / `usageprofile` / `vipre164transformation`
reference categories were schema-verified against CUCM 15. If a future
CUCM version adds new `fkcallingsearchspace_*` columns,
`route_devices_using_css`'s coverage will lag until the package is
updated. The
`test_complete_schema_coverage_against_known_columns` test enforces
the current snapshot — failing red surfaces the drift loudly.
