Connect AI agents to databases, data warehouses, cloud storage, and SaaS apps to query, analyze, join, validate, and transform data across multiple sources.
OpenClaw is a self-hosted agent gateway. It connects to remote MCP servers over streamable HTTP, configured in one file.
This guide connects Marcopolo MCP to OpenClaw through MewCP, so OpenClaw can use Marcopolo MCP's 5 tools, like workspace_shell, connections_list and data_query, without your Marcopolo MCP credentials ever reaching the app.
Marcopolo MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Marcopolo MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Marcopolo MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
Edit ~/.openclaw/openclaw.json. Create it if it doesn't exist.
Restart OpenClaw. Sign in when the browser window opens.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Run a shell command in the persistent /workspace runtime. Use for all agent-side work: query authoring, analytics, DuckDB joins, workspace files, scripts, git, diagnostics, and cron. The `connection` and `cron` CLIs exist only inside this runtime and must be invoked through this tool.
List visible Marcopolo connections and their provider authorization state. Use only entries with `queryable: true` for `data_query`. Entries with `authorization_state: "authorization_required"` need user authorization from Connections in Marcopolo; follow `next_actions`. Capabilities and workspace paths describe supported commands for authorized connections.
Run a bounded governed query against a visible connection. Use this tool in generated code that re-queries live data at view or load time: Remote Artifacts, external web apps, scheduled scripts, and any other programmatic interface that fetches fresh data on each run. Do NOT use it for agent-side analytics or one-off snapshot visualizations — use the `workspace_shell` tool with the connection query CLI instead. Pass the full workspace-relative `query_file` path including the connection prefix, e.g. `connections/<name>/queries/<file>`. Paths resolve from `/workspace`, not from any current directory. Author new query files through `workspace_shell` before calling this tool so query text is durable and reusable. Returns `rows` as a parsed list of record dicts and `row_count` as the total — no JSON parsing needed. Results are capped by `max_rows` (1–5000).
Create a browser setup URL for a credentialed connection. Use a canonical `type` when known; otherwise pass `intent_text`. For hosted demo data with no credentials, use `install_demo_connection`.
Install hosted demo data with no user credentials. Pass a demo id or natural-language request. Use `connection_setup` for real user-owned connections.
