Froglet — Claude Code MCP server: setup
Froglet records agent operations with signatures and hash links, then supports offline checks. It fits local data sharing and bounded Wasm jobs.
claude mcp add froglet -- npx -y froglet-mcpWhat Froglet does
Froglet runs as a local MCP server for selected-data exchange and bounded Wasm computation. An agent can prepare JSON, typed CSV, or SQLite data, run a local example, request publication approval, and return a service share link.
Each operation gets a signed, hash-linked record covering the authorization, limits, and the executor’s attestation. The chain can be checked offline without a node or account. Froglet is listed for Claude Code, Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline, Zed, and Gemini CLI. The host must stay online while the service runs.
What it helps with
- share selected data with another agent
- run a bounded Wasm function locally
- verify a signed operation chain offline
- publish a service and return its share link
- record execution limits and attestation
Example prompts for the agent
- Prepare the selected records from
catalog.jsonand publish them as a Froglet service. - Run a local Wasm function with the given budget and return a verifiable receipt.
- Check the Froglet operation chain offline and report any broken signature.
