Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
Tool Guardian acts as an intelligent intermediary fronting MCP servers and native DSH tools. Instead of injecting dozens of raw tool schemas into the context window on every prompt (which can consume tens of thousands of tokens), it exposes a lightweight discovery router (~300 tokens) with progressive disclosure. It also provides an output shaping ladder that compresses oversized results while archiving originals for on-demand retrieval.

Key Capabilities

  • Reduces prompt context consumption by replacing static tool schema dumps with on-demand discovery (list_capabilities, describe_tool, call_tool)
  • Shapes and truncates large execution outputs across tools with lossless cleaning, sampled diffs, and error summaries
  • Preserves oversized tool output into an archive accessible via retrieve_spill
  • Detects and manages shell tool execution bypasses with configurable logging, nudges, or denials
  • Supports session state persistence and cost-weighted tool grouping for MCP servers and native DSH tools

Useful For

  • Preventing context exhaustion when connecting multiple MCP servers to DeepSeek Harness or local LLMs
  • Controlling context bloat caused by verbose terminal logs, JSON arrays, or diffs during development tasks
  • Tracking and debugging model tool selection behavior with detailed bypass summaries and call logs

Who It Fits

  • DeepSeek Harness users orchestrating multiple MCP servers
  • Developers working with context-constrained local models (e.g., via Ollama)
  • AI agent engineers needing fine-grained token budgeting and output shaping

Documented Limitations

  • Requires Python 3.9+ installed and accessible on PATH or configured in settings
  • Supports stdio MCP servers only; HTTP/SSE endpoints are currently unsupported
  • Relies on the model's ability to proactively discover and invoke tools rather than having them preloaded
  • Does not provide a standalone visual card in the DSH web UI; configured via settings.yaml or Cordis patch
