Compatible with every major AI agent and IDE
What is the Filebase (Web3 Storage) MCP Server?
Connect your Filebase account to any AI agent and take full control of your decentralized Web3 storage workflows through natural conversation.
What you can do
- IPFS Operations — Add text files, fetch content by CID, and manage raw blocks directly on the IPFS network using the RPC API.
- Pinning Management — Use the Pinning Service API (PSA) or RPC to pin, list, and remove content identifiers (CIDs) for persistent storage.
- IPNS & Keys — Generate keypairs, publish CIDs to IPNS, and resolve names to IPFS paths for mutable decentralized websites.
- Usage & Infrastructure — Monitor storage usage, manage dedicated gateways, and track bucket metrics across the platform.
How it works
- Subscribe to this server
- Enter your Filebase API Key and Platform Token
- Start managing your Web3 assets from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — interact with IPFS and IPNS directly from your coding environment without switching to CLI or web dashboards.
- DevOps Engineers — automate pinning and storage monitoring as part of your infrastructure workflows.
- Content Creators — manage decentralized assets and metadata for NFTs or dApps using simple natural language commands.

Why Cursor?
Cursor's Agent mode turns Filebase (Web3 Storage) into an in-editor superpower. Ask Cursor to generate code using live data from Filebase (Web3 Storage) and it fetches, processes, and writes. all in a single agentic loop. 29 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Filebase (Web3 Storage) for Cursor
Every tool call from Cursor to the Filebase (Web3 Storage) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I pin a specific CID to ensure it stays on the network?
You can use the rpc_pin_add tool by providing the CID. This ensures the content is persistently stored on Filebase's IPFS infrastructure.
Can I check my current storage usage and limits?
Yes! Use the platform_get_usage tool. It will return your total storage used, bandwidth metrics, and current subscription limits.
How do I publish a CID to a mutable IPNS name?
Use the rpc_name_publish tool with the target CID. This maps your content to an IPNS address that stays the same even when the content updates.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
