Glama MCP Gateway
Connect through Glama MCP Gateway for full control over tool access and complete visibility into every call.
Full call logging
Every tool call is logged with complete inputs and outputs, so you can debug issues and audit what your agents are doing.
Tool access control
Enable or disable individual tools per connector, so you decide what your agents can and cannot do.
Managed credentials
Glama handles OAuth flows, token storage, and automatic rotation, so credentials never expire on your clients.
Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4/5 across 5 of 5 tools scored.
The tools are mostly distinct with clear purposes: drug overdoses, infant mortality, leading causes, state comparisons, and provisional data. However, 'get_leading_causes_of_death' and 'get_mortality_by_state' both use the same underlying dataset (NCHS Leading Causes of Death) and could cause confusion about which to use for state-level mortality analysis, creating minor overlap.
All tools follow a consistent 'get_[specific_data_type]' naming pattern using snake_case. This predictable structure makes it easy for agents to understand what each tool retrieves without ambiguity in naming conventions.
With 5 tools, this server is well-scoped for accessing CDC mortality data. Each tool covers a distinct aspect of mortality statistics (drug overdoses, infant mortality, leading causes, state comparisons, provisional data), providing comprehensive coverage without being overwhelming or too sparse.
The toolset provides excellent coverage of key mortality data domains with clear retrieval capabilities. Minor gaps exist in update/delete operations (which may not be applicable for read-only public health data) and potentially in demographic breakdowns beyond state and race/ethnicity, but agents can effectively work with the available data for most mortality analysis tasks.
Available Tools
5 toolsget_drug_overdose_deathsInspect
Get provisional drug overdose death data by state.
Returns provisional counts and rates of drug overdose deaths from the
National Vital Statistics System (NVSS). Includes data on opioid,
synthetic opioid, and other drug-involved deaths. Updated monthly.
Args:
state: Filter by state name (e.g. 'West Virginia', 'Ohio').
Case-insensitive. Returns all states if not specified.
year: Filter by year. Returns all available years if not specified.
limit: Maximum number of records to return (default 25, max 1000).
| Name | Required | Description | Default |

| result | Yes |
get_infant_mortalityInspect
Get infant mortality rates by state and race/ethnicity.
Returns infant mortality data including rates per 1,000 live births,
broken down by state and race/ethnicity. Infant mortality is a key
indicator of community health status used in CHNAs.
Args:
state: Filter by state name (e.g. 'Ohio', 'Georgia'). Case-insensitive.
Returns all states if not specified.
year: Filter by year. Returns all available years if not specified.

get_leading_causes_of_deathInspect
Get leading causes of death with death counts and age-adjusted rates.
Returns data from the NCHS Leading Causes of Death dataset, which provides
national and state-level mortality statistics by cause of death, year, and
age-adjusted death rate per 100,000 population. Data spans 1999-2017.
Args:
state: Filter by state name (e.g. 'California', 'Texas'). Case-insensitive.
Returns all states if not specified.
year: Filter by year (e.g. 2017). Returns all available years if not specified.
limit: Maximum number of records to return (default 25, max 1000).
| Name | Required | Description | Default |

get_mortality_by_stateInspect
Compare mortality rates across states for a specific cause or all causes.
Returns age-adjusted death rates by state, useful for comparing mortality
burdens across geographies. Data from NCHS Leading Causes of Death.
Args:
cause: Cause of death to filter by (e.g. 'Heart disease', 'Cancer',
'Unintentional injuries', 'Alzheimer\'s disease'). Partial match
supported. Returns all causes if not specified.
year: Filter by year (e.g. 2017). Defaults to most recent available year
if not specified.
| Name | Required | Description | Default |

get_provisional_mortalityInspect
Get most recent provisional mortality data including COVID and other causes.
Returns provisional death counts from the NVSS, covering major cause
groups including COVID-19, respiratory diseases, circulatory diseases,
and more. Data is updated weekly and covers the most recent periods.
Args:
state: Filter by state/jurisdiction name (e.g. 'New York', 'Florida').
Case-insensitive. Returns all jurisdictions if not specified.
cause_group: Filter by cause group (e.g. 'COVID-19', 'Respiratory',
'Circulatory', 'Malignant neoplasms'). Partial match supported.
Returns all cause groups if not specified.
limit: Maximum number of records to return (default 50, max 1000).
