Sinim

Pull Chilean municipal data from SINIM without memorizing variable codes or wrestling with raw exports. Search the catalog, build tidy municipal panels, and use the same package from Python or any MCP-compatible client.

What You Can Do

• Search roughly 480 SINIM variables by natural language instead of memorizing id_dato codes.
• Pull one or many municipal indicators as tidy pandas panels in one call.
• Discover available years and municipality codes directly from the live portal.
• Use the same package in notebooks, scripts, or MCP clients.
• Work with an offline catalog snapshot plus optional metadata caching.

Installation

pip install mcp-sinim

Python Example

from mcp_sinim import SINIMClient

client = SINIMClient(corrmon=True)

# 1) Find the right variable code
hits = client.search("patentes municipales")
print(hits[["code", "name"]].head(3).to_string(index=False))

# 2) Pull a tidy municipal panel
df = client.get(
    ["4173", "1311"],
    years=[2024],
    municipios=["13101", "13114", "13119"],  # Santiago, Las Condes, Providencia
)
print(df.head().to_string(index=False))

# 3) Explore metadata when needed
print(client.years()[-5:])
print(client.search_municipios("providencia"))

Main things you will use:

• search(...) to find variable codes
• get(...) to pull municipal data
• municipios(...) and search_municipios(...) to work with legal municipality codes
• years() to see what is currently available

MCP Server

Use mcp-sinim when you want an MCP client to search SINIM variables, inspect their metadata, and fetch municipal data without writing a custom wrapper.

Run the server after installation:

mcp-sinim

Typical MCP configuration:

{
  "mcpServers": {
    "sinim": {
      "command": "mcp-sinim"
    }
  }
}

Optional environment variable:

• MCP_SINIM_CACHE_DIR for the metadata disk cache

MCP tools

Tool	Description
search_variables	Search the SINIM variable catalog by keyword.
get_variable_info	Return metadata for one SINIM variable code.
get_data	Retrieve tidy municipal records for one or many variables.
list_areas	List the 9 catalog subject areas.
list_municipios	List municipalities, optionally filtered by region.
list_years	List currently available SINIM years.

Important Notes

• cod_municipio matches the official SUBDERE CUT codes for the 345 municipalities present in SINIM.
• corrmon=True requests SINIM's real-value series, expressed in pesos of the most recent published year.
• This is an independent open-source client for the public SINIM portal. It is not affiliated with SUBDERE or the Gobierno de Chile.
