List the court deadline types 1Court can calculate for a jurisdiction. Available ids: TX; CA (civil), CA-FAM (family), CA-PROB (probate), CA-UD (unlawful detainer), CA-SC (small claims), CA-GOV (government claims), CA-CRIM (criminal), CA-JUV (juvenile dependency and delinquency), CA-PRESUIT (employment, housing and pre-suit clocks: foreclosure, HOA, ADA/Unruh, FEHA, EEOC, PAGA, arbitration fees, med-mal notice, CEQA, mechanics liens), CA-AGENCY (WCAB, OAH, CUIAB, SPB, PERB, Labor Commissioner, Cal/OSHA Appeals Board, Office of Tax Appeals, DMV, CPUC, ALRB, State Bar Court), CA-SPECIAL (eminent domain, elections, LPS, elder abuse, traffic), CA-APP (appeals and writs), CA-SOL (statutes of limitations); US (federal civil and appellate), US-BK (bankruptcy).

Returns each deadline with the governing rule citation for each. Use before calculate_deadline to get valid deadline_type ids.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http 1court-directory-mcp https://state.1court.ai/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add 1court-directory-mcp --url https://state.1court.ai/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable 1court-directory-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "1court-directory-mcp": {
      "url": "https://state.1court.ai/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "1court-directory-mcp": {
      "type": "streamableHttp",
      "url": "https://state.1court.ai/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start 1court-directory-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "1court-directory-mcp": {
      "type": "http",
      "url": "https://state.1court.ai/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http 1court-directory-mcp https://state.1court.ai/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "1court-directory-mcp": {
      "url": "https://state.1court.ai/api/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "1court-directory-mcp": {
      "serverUrl": "https://state.1court.ai/api/mcp"
