# Mexico — PSM Mexico Lookup

**Live, direct-to-government access to Sistema Electrónico de Publicaciones de Sociedades Mercantiles (PSM), Secretaría de Economía (SE).**

> Single-country variant of the cross-border [Cross-Border UBO Chain Walker](../ubo-cross-border-chain-walker/SKILL.md). Use this skill when the user is explicitly focused on **Mexico**.

## What you get

- **Direct query to PSM Mexico.** Every tool call hits Sistema Electrónico de Publicaciones de Sociedades Mercantiles (PSM), Secretaría de Economía (SE) at the moment you ask. No nightly scrape, no aggregator middle layer.
- **Unmodified responses.** Field names, status codes, and (where available) raw filing bytes are returned exactly as the registry's own system emits them.
- **Native ID format support.** PSM publication ID per filing; companies are identified by name + tax ID (RFC).
- **Sample entity:** A Mexican S.A. de C.V..

## Available tools (jurisdiction = `MX`)

`search_companies`, `list_filings`, `get_document_metadata`, `fetch_document`

For every tool, pass `jurisdiction: "MX"` (case-insensitive).

## Example prompts

```
Search PSM for any publication mentioning a Mexican S.A. de C.V.
```

```
Download a PSM corporate-acts publication
```

```
List recent PSM filings
```

## Workflow

### Step 1 — Resolve the entity
```
search_companies({ jurisdiction: "MX", query: "<name or ID>" })
get_company_profile({ jurisdiction: "MX", company_id: "<id>" })
```

### Step 2 — Pull the relevant register slice
Pick from the available tools list above. For UBO walks across borders, return to the [Cross-Border UBO Chain Walker](../ubo-cross-border-chain-walker/SKILL.md).

## Quirks specific to Mexico

- PSM is the **publication channel** (like Spanish BORME), not the company register itself — Mexican companies file at state-level Registros Públicos de Comercio (RPC).
- PSM publishes corporate acts: incorporations, mergers, dissolutions, etc. `fetch_document` returns the raw publication.
- Mexican company types: `S.A. de C.V.` (variable-capital limited), `S.A.P.I.` (investment), `S. de R.L. de C.V.`.
- RFC (Registro Federal de Contribuyentes) is the tax identifier — separate from PSM publication IDs.

## Provenance

- **Registry**: Sistema Electrónico de Publicaciones de Sociedades Mercantiles (PSM), Secretaría de Economía (SE)
- **Government URL**: <https://psm.economia.gob.mx/>
- **OpenRegistry jurisdiction code**: `MX`
- **Underlying MCP server**: `https://openregistry.sophymarine.com/mcp`
