# How to Integrate MCP Servers with OpenClaw Agents

MCP integration lets OpenClaw agents connect to external tools like file storage servers. Access Fastio's consolidated MCP toolset for uploads, workspaces, AI queries, and shares.

This how-to guide walks through setup, authentication options (API key, PKCE), core workflows, and troubleshooting. Includes code examples, agent use cases, and production tips. Fastio offers a 14-day Business Trial at /pricing/.

## What Is OpenClaw MCP Integration?

OpenClaw MCP integration connects OpenClaw agents to Model Context Protocol servers for standardized tool access. MCP standardizes how AI agents call external APIs, handling authentication and session state automatically.

Fastio runs a production remote MCP server at `https://mcp.fast.io/mcp` with a consolidated MCP toolset mapped to its full REST API. These cover account management, organization creation, workspace operations, storage, and shares.

Fastio supports Streamable HTTP at `/mcp` and legacy SSE at `/sse`. OpenClaw agents gain persistent collaboration without managing database instances or S3 configurations.

### Key Components

- **Remote MCP Server**: Connect to `https://mcp.fast.io/mcp` with Streamable HTTP or SSE transports. Exposes Fastio's consolidated MCP toolset.

- **Fastio API**: Full REST backend for storage operations.

## Prerequisites for Setup

Gather these for OpenClaw MCP integration:

* OpenClaw installed in your runtime environment
* Node.js or Python environment for agent workflows
* Fastio account with an API key from organization settings
* Access to Fastio's remote MCP endpoint at `https://mcp.fast.io/mcp`

Fastio offers a 14-day Business Trial (credit card required), with plans scaling from Starter to Business and Growth at [/pricing/](/pricing/). Agents connect using scoped, long-lived API keys.

## How to Install Fastio MCP Skill in OpenClaw

Connect OpenClaw to Fastio's remote MCP server:

Add the Fastio MCP endpoint to your OpenClaw agent configuration:
```json
{
  "mcpServers": {
    "fastio": {
      "url": "https://mcp.fast.io/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_FASTIO_API_KEY"
      }
    }
  }
}
```

No local packages or container setups are required. The remote server handles tool execution and session state.

Restart your OpenClaw agent to establish the connection and verify that workspace and storage tools are active.

## How to Authenticate Your Agent

Authenticate your agent using Fastio credentials or API keys:

### Scoped API Key (Recommended)
Generate a long-lived, scoped API key from [Fastio Settings > API Keys](https://go.fast.io/settings/api-keys) and append it to your MCP URL (`https://mcp.fast.io/mcp/key`) or pass it in the authorization header.

### PKCE Browser Login
For human-in-the-loop and supervised interactive sessions, agents can initiate PKCE login to request temporary scoped access through a browser approval window.

Sessions remain active with scoped API keys, providing dependable authentication for unattended agent workflows.

## How to Use Core MCP Tool Workflows

Common workflows using Fastio's consolidated MCP toolset:

**1. Create Workspace**
Agents create project workspaces and enable Intelligence for automatic indexing:
- Specify workspace name and organization ID.
- Toggle Intelligence on to enable RAG indexing and search.

**2. Upload Files and Media**
Agents upload text documents, spreadsheets, PDFs, or media files directly into workspace folders. Fastio supports resumable chunked uploads for large assets.

**3. Document Chat and Semantic Search**
Once Intelligence is enabled on the workspace, agents can perform natural-language queries across documents with source citations.

**4. Branded Shares and Human Handoff**
Create branded Send, Receive, or Exchange portals with expiration dates and password protection. When project tasks wrap up, agents can generate an organization claim link (`https://go.fast.io/claim?token=...`) to hand off complete ownership to a human stakeholder while retaining administrative access.

## How to Troubleshoot Common Issues

Common issues and fixes:

* **No tools visible**: Verify that the remote MCP URL is reachable and that your OpenClaw configuration points to `https://mcp.fast.io/mcp`.
* **Auth fails**: Check that your scoped API key is active in Fastio settings and passed correctly in the URL or request header.
* **Storage limits**: Check your plan quota in the Fastio dashboard and upgrade your plan if storage or credit limits are reached.
* **RAG returns empty results**: Confirm that Intelligence is toggled ON for the workspace. Backlog indexing takes a few moments for newly added files.
* **Handoff link expired**: Transfer tokens expire if not claimed within the designated window. Generate a new claim link to complete the transfer.

## Frequently asked questions

### How do I integrate MCP with OpenClaw?

Connect OpenClaw to Fastio's remote MCP server at `https://mcp.fast.io/mcp`. Authenticate with a scoped API key to access workspaces, files, and AI search.

### What OpenClaw MCP server examples exist?

Examples include creating workspaces, uploading deliverables, running semantic search with citations, creating branded share links, and handing off organizations.

### What are Fastio's pricing and trial options?

Fastio offers a 14-day Business Trial (credit card required). Plans scale from Starter ($29/mo, 1 TB) to Business ($99/mo, 10 TB) and Growth ($299/mo, 50 TB) at /pricing/.

### Can OpenClaw agents collaborate real-time?

Yes, shared workspaces show presence, anchored comments (video timestamps/images), and activity feeds. File version history and audit logs coordinate updates.

### What tools are included in Fastio's MCP server?

Fastio provides a consolidated MCP toolset covering auth, orgs, workspaces, storage, versioning, shares, AI chat, and comments.

Yes, Fastio supports large file uploads with chunking and resumable streaming via the API and MCP server.

### How to hand off to human?

Create an organization transfer token and share the claim link (https://go.fast.io/claim?token=...). The human claims ownership while the agent retains admin access.

### RAG setup in OpenClaw?

Enable Intelligence on the workspace. Query files with Ripley AI chat scoped to folders or documents, with citations included.

## About Fast.io

Fast.io provides shared workspaces where people and AI agents work on the same files, with built-in semantic search and citation-backed chat over what they hold. Agents reach it through a remote MCP server at https://mcp.fast.io/mcp, a REST API at https://api.fast.io/current/, and a command line client published on npm as @vividengine/fastio-cli.
