CREA DDF MCP
Use this skill to run DDF as a governed MCP/CLI integration for downstream analysis and automations.
Workflow
1. Configure DDF credentials
Set environment variables:
DDF_BASE_URLDDF_AUTH_URLDDF_TOKEN_GRANT(client_credentialsorpassword)DDF_CLIENT_ID+DDF_CLIENT_SECRET(for client credentials)DDF_USERNAME+DDF_PASSWORD(for password grant)
Optional operational controls:
DDF_HTTP_TIMEOUT_MS,DDF_HTTP_RETRIES,DDF_HTTP_RPS,DDF_HTTP_BURSTDDF_MEDIA_ENTITY,DDF_MEDIA_RECORD_KEY_FIELD,DDF_MEDIA_ORDER_FIELD
2. Build and run MCP
npm --workspace @fub/crea-ddf-mcp run build
node packages/crea-ddf-mcp/dist/mcp-server.js
3. Validate with CLI
npm --workspace @fub/crea-ddf-mcp run dev:cli -- search-properties --filters-json '{"city":"Toronto"}' --top 5
npm --workspace @fub/crea-ddf-mcp run dev:cli -- get-property --id "<ListingKey>"
npm --workspace @fub/crea-ddf-mcp run dev:cli -- get-metadata
4. Wire into Claude MCP/OpenClaw
Use references/claude-mcp-config.md for Claude setup and references/openclaw-wiring.md for OpenClaw runtime wiring.
Safety Rules
- Prefer typed tools (
ddf.search_properties,ddf.get_property) over raw calls. - Keep field selections to allowlisted safe sets unless governance is updated.
- Treat data licensing/display obligations as upstream policy requirements.
- Never store credentials in plaintext files committed to git.
