Streamparse

Overview

Streamparse is a Model Context Protocol server that handles partial, truncated, or malformed JSON data for LLM tool calls and structured outputs. Any MCP-compatible AI assistant can invoke Streamparse's tools directly during conversations or agent workflows, letting the model decide when to apply robust JSON parsing to messy input.

The server runs locally via the npm package @mukundakatta/streamparse-mcp, communicating over stdio without requiring any credentials or authentication. Version v1.0.1 is available now under the MIT license, with full source code at MukundaKatta/streamparse-mcp on GitHub.

Streamparse belongs in the AI & Agents category on mcp.site and integrates with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. Maintainers are invited to claim this listing to verify ownership, display the Verified badge, and ensure information stays accurate.
