Model routing for AI agents: delegate bulk reads & boilerplate to cheap worker models.

67 Trust /100
Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency32
Schema Quality & AI Usability80
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 365 tokens (~121/item across 3 items; 3 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
  • Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Install

How do I install the io.github.yasmanycastillo/model-shunt MCP server?

io.github.yasmanycastillo/model-shunt runs locally as a PyPI package, launched with uvx model-shunt. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~365 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
bulk_read ~132

Reads multiple or large files and answers a targeted question using a cheap, fast worker model (e.g. Gemini Flash, Groq, Ollama). Saves ~90% tokens by returning only structured bullet points.

NameTypeReqDescription
file_pathsarrayyesList of file paths to analyze
modelstring–Optional model override (or 'auto' to select the best available reader model)
providerstring–Optional provider override (gemini, groq, openai, deepseek, anthropic, ollama, openrouter)
questionstringyesThe specific question to answer about the files

No output schema declared.

No examples provided.

code_write ~148

Generates boilerplate code (tests, mocks, stubs, configs) matching the patterns of a reference file. Can write directly to disk without consuming frontier output tokens.

NameTypeReqDescription
modelstring–Optional model override (or 'auto' to select the best available writer model)
providerstring–Optional provider override (gemini, groq, openai, deepseek, anthropic, ollama, openrouter)
reference_pathstringyesPath to reference file whose conventions, style, and structure should be replicated
specstringyesDescription of what code to generate
target_pathstring–Optional path where generated code should be written directly on disk

No output schema declared.

No examples provided.

get_available_models ~85

Discovers active models from the worker provider and recommends the best model for reading (high context / low cost) and writing (code intelligence). Enables calling agents to delegate dynamically to the best model.

NameTypeReqDescription
providerstring–Optional provider to query (gemini, groq, openai, deepseek, anthropic, ollama, openrouter). Defaults to active provider.

No output schema declared.

No examples provided.
