This server exhibits severe definition quality issues across all dimensions. Critical defects include: (1) Massive duplicate tool definitions, tools 1-5 are duplicated as 8-12, 15-19, and 23-27 with only minor description changes (demo vs Excel vs MySQL vs PostgreSQL variants). This violates the single-responsibility principle and causes LLM disambiguation failure. (3) Descriptions are vague and lack actionable context (e.g., 'Get Results dimension metrics (D_R)' tells the agent nothing about when to call it vs. similar tools, what fields are returned, or prerequisites). (4) No parameter descriptions, no enums, no constraints, no error guidance. (5) Output schemas completely undocumented, agents cannot know what fields to expect or chain calls. (6) No security hardening, no pagination support, no rate limiting. The codebase snippet shows incomplete implementation (truncated __init__). This server is non-functional for production agent integration.

Massive tool name collision: get_results_metrics, get_process_metrics, get_support_metrics, get_longterm_metrics, get_all_metrics each appear 4 times across different backends (demo, excel, mysql, postgres). LLMs cannot disambiguate and will select unpredictably. Violates naming uniqueness and composition principles.
CRITICAL: Rename all tools to include backend identifier in the tool name, not just the description. E.g., get_results_metrics_demo, get_results_metrics_excel, get_results_metrics_mysql, get_results_metrics_postgres. This prevents LLM disambiguation failures and violates the composition principle.
CRITICAL: Add explicit input schemas to ALL tools. For tools with no parameters (get_results_metrics, list_scenarios, etc.), explicitly declare input as {"type": "object", "properties": {}, "required": []}. For query_custom, add type and description: {"filter_expr": {"type": "string", "description": "Pandas query expression using column names and operators (e.g., 'value > 0.5 and name == "target"'). See pandas.DataFrame.query() documentation."}}
CRITICAL: Document output schemas for ALL tools. Example for get_results_metrics: Return {"type": "object", "properties": {"retention_rate": {"type": "number"}, "target_retention": {"type": "number"}, "customer_satisfaction": {"type": "number"}, "nps_score": {"type": "number"}}, "required": ["retention_rate", "target_retention", "customer_satisfaction", "nps_score"]}. This enables agents to chain calls and extract data.
Expand tool descriptions to 50-200 chars following LLM-optimized patterns: (1) What does it do? (2) When should I call it? (3) What data does it return? Example: 'get_results_metrics_demo: Retrieve key performance indicators for the Results dimension (D_R) from the demo dataset. Returns retention_rate, customer_satisfaction, nps_score, and target metrics. Call this to understand why performance gaps exist in customer outcomes.'

ALL 30 tools have empty input schemas ({}). Per hard scoring rules, schema score MUST be 0. Agents cannot know what parameters to pass, what constraints apply, or what values are valid. Zero tools are actionable without additional documentation.
Tool descriptions are vague, generic, and under 20 characters for most tools (e.g., 'Get Results dimension metrics (D_R)' is 36 chars but provides zero context on when to call it, what data it returns, or dependencies). Most descriptions do not explain WHAT the tool does, WHEN to use it, or WHAT it returns.
No output schemas documented. Agents do not know what fields to expect from any tool response. Cannot chain tool calls or extract required data (e.g., does get_results_metrics return a dict with keys like retention_rate, target_retention, or something else?). Blocks downstream tool composition.
query_custom tools (pandas, mysql, postgres) accept a filter_expr or query parameter with NO type specification, NO description of valid syntax, NO enum constraints, NO examples. LLMs will guess at SQL syntax, pandas syntax, or make up expressions. Violates parameter documentation and constrained input rules.
set_scenario tool description states 'Switch to a different demo scenario' but does not explain: (1) What scenarios are valid? (2) What happens to current state? (3) Is the change persistent? (4) Can this be called during agent reasoning or only before? No enum on scenario param; agent must guess or call list_scenarios first.
connect/disconnect tools (mysql, postgres) have no descriptions explaining: (1) Are connections stateful or do they auto-close? (2) Must connect be called before querying or is it implicit? (3) Is disconnect required or optional? (4) What happens if connect is called twice? Agents cannot plan multi-step workflows without this clarity.
No error handling guidance. Tools declare no error scenarios or recovery paths. If set_scenario is called with an invalid scenario ID, or if query_custom fails due to syntax error, agents have no guidance on what to try next. Violates recovery-guide and error-classification patterns.
Tool definitions appear inferred rather than explicitly registered in visible code. Source code snippet is truncated (__init__ incomplete). Cannot verify actual schema registration, parameter validation, or error handling implementation.
All 30 tools
Add enum constraints to set_scenario's scenario parameter. Document valid options: {"scenario": {"type": "string", "enum": ["banking_retention", "banking_aum", "healthcare_readmission"], "description": "The scenario identifier to switch to. Call list_scenarios to see all options."}}
Add explicit descriptions to query_custom filter_expr and query parameters with syntax guidance: (1) For pandas: 'Pandas query expression (e.g., 'value > 0.5' or 'column_name == "target"'). See pandas.DataFrame.query() docs.' (2) For MySQL/PostgreSQL: 'Standard SQL WHERE clause syntax (e.g., 'value > 0.5 AND name = "target"'). Do not include the WHERE keyword.'
Add dependency documentation to connect/disconnect. Example: 'connect (mysql): Establish a stateful connection to MySQL. Must be called before any query_custom calls. Calling connect multiple times resets the connection. Returns {"status": "connected", "message": "Connected to MySQL as user@host"}.'
Implement error handling with recovery guidance. Tools should return error objects like {"error": "invalid_scenario", "message": "Scenario 'unknown' not found. Available scenarios: banking_retention, banking_aum, healthcare_readmission. Try set_scenario(scenario='banking_retention')"}
Add pagination support to list_scenarios and get_all_metrics if they return large result sets. Include limit and offset parameters and return {"items": [...], "total": N, "limit": limit, "offset": offset}
Document which tools are idempotent (safe to retry) vs. stateful (side effects). E.g., get_results_metrics is idempotent; set_scenario is not (changes agent state). Mark stateful tools in descriptions: 'WARNING: This tool modifies state. Repeated calls with the same input may produce different results.'
Add a discovery tool like get_scenario_schema(scenario_id) that returns the expected structure of data for a scenario, helping agents understand what fields and ranges to expect before querying.
Remove duplicate tool definitions across backends or consolidate them into a single parameterized tool (e.g., get_metrics(dimension, backend='demo|excel|mysql|postgres') with sensible defaults).
