Read-only MCP server for Cisco Unified CM 15 AXL — built for LLM-driven
cluster auditing, with a particular focus on the Route Plan Report:
partitions, calling search spaces, route patterns, translation patterns,
called/calling party transformations, and digit-discard instructions.
Pairs intentionally with the sibling mcp-cisco-docs server (live
cluster state + vendor docs in one LLM context).
Architecture:
- zeep SOAP client to CUCM AXL
- WSDL bootstrap from Cisco's axlsqltoolkit.zip (auto-extract on
first launch; zip is gitignored, vendor-licensed)
- SQLite response cache at ~/.cache/mcp-cucm-axl/responses/
- Schema-grounded prompts that pull chunks from the sibling
cisco-docs index (docs_loader.py)
Read-only by structural guarantee — never registers AXL write methods
(no executeSQLUpdate, no add*/update*/remove*/apply*/reset*/restart*
tools). SQL queries also client-side validated (sql_validator.py) to
begin with SELECT or WITH.
Tools exposed:
Foundational: axl_version, axl_sql, axl_list_tables,
axl_describe_table, cache_stats, cache_clear
Route plan: route_partitions, route_calling_search_spaces,
route_patterns, route_inspect_pattern,
route_lists_and_groups, route_translation_chain,
route_digit_discard_instructions
Prompts (schema-grounded):
route_plan_overview, investigate_pattern, audit_routing,
cucm_sql_help
Tests cover cache, docs_loader, normalize, sql_validator, wildcard.
