# Coupler.io Read-only data access via Coupler.io's MCP server. **Author:** Coupler.io Team **Homepage:** [coupler.io](https://coupler.io) ## Prerequisites - [mcporter](https://github.com/openclaw/mcporter) CLI installed and on PATH - Coupler.io account with at least one data flow configured to OpenClaw destination ## Quick Reference ```bash mcporter call mcp-coupler-io-mcp.list-dataflows mcporter call mcp-coupler-io-mcp.get-dataflow dataflowId=<uuid> mcporter call mcp-coupler-io-mcp.get-schema executionId=<exec-id> mcporter call mcp-coupler-io-mcp.get-data executionId=<exec-id> query="SELECT * FROM data LIMIT 10" ``` --- ## Connection Setup > **Endpoint verification:** This skill connects to `auth.coupler.io` (OAuth) and `mcp.coupler.io` (MCP data). These are official Coupler.io endpoints. You can verify them via your Coupler.io account (AI integrations page). > **Transport:** This MCP uses **streamable HTTP**, not SSE. If you see "SSE error" in output, ignore the misleading label — it's still HTTP. ### 1. Authenticate and add server in one step **Do not** use `mcporter config add` followed by `mcporter auth` separately — this creates a config entry without auth metadata and causes a 401 loop. Instead, do it all in one command: ```bash mcporter auth --http-url https://mcp.coupler.io/mcp --persist config/mcporter.json ``` This auto-detects OAuth, opens the browser for Coupler.io login (PKCE flow), and saves the server definition + tokens on success. To re-authenticate or clear stale tokens: ```bash mcporter auth --http-url https://mcp.coupler.io/mcp --persist config/mcporter.json --reset ``` ### 2. Ensure `"auth": "oauth"` is in config After auth, check `config/mcporter.json`. mcporter won't use cached tokens unless the entry has `"auth": "oauth"`. It should look like: ```json { "mcpServers": { "mcp-coupler-io-mcp": { "baseUrl": "https://mcp.coupler.io/mcp", "auth": "oauth" } } } ``` If `"auth": "oauth"` is missing, add it manually. ### 3. Verify ```bash mcporter list mcp-coupler-io-mcp ``` Should return 4 tools: `get-data`, `get-schema`, `list-dataflows`, `get-dataflow`. > **Note:** The server name is auto-generated as `mcp-coupler-io-mcp` from the URL. Use this name in all subsequent commands. --- ## Token Refresh mcporter handles token refresh automatically on 401 errors. No manual intervention needed. If you need to force a fresh token: `mcporter auth mcp-coupler-io-mcp --reset` --- ## MCP Tools ### list-dataflows List all data flows with OpenClaw destination. ```bash mcporter call mcp-coupler-io-mcp.list-dataflows --output json ``` ### get-dataflow Get flow details including `lastSuccessfulExecutionId`. ```bash mcporter call mcp-coupler-io-mcp.get-dataflow dataflowId=<uuid> --output json ``` ### get-schema Get column definitions. Column names are in `columnName` (e.g., `col_0`, `col_1`). ```bash mcporter call mcp-coupler-io-mcp.get-schema executionId=<exec-id> ``` ### get-data Run SQL on flow data. Table is always `data`. ```bash mcporter call mcp-coupler-io-mcp.get-data executionId=<exec-id> query="SELECT col_0, col_1 FROM data WHERE col_2 > 100 LIMIT 50" ``` **Always sample first** (`LIMIT 5`) to understand structure before larger queries. --- ## Typical Workflow ```bash # 1. List flows, find ID mcporter call mcp-coupler-io-mcp.list-dataflows --output json # 2. Get execution ID mcporter call mcp-coupler-io-mcp.get-dataflow dataflowId=<id> --output json # 3. Check schema mcporter call mcp-coupler-io-mcp.get-schema executionId=<exec-id> # 4. Query mcporter call mcp-coupler-io-mcp.get-data executionId=<exec-id> query="SELECT * FROM data LIMIT 10" ``` --- ## Constraints - Read-only: cannot modify flows, sources, or data - Only flows with OpenClaw destination are visible - Tokens expire in 2 hours (mcporter refreshes automatically)
