Crate ironcontext_core 

IronContext — security & optimization engine for the Model Context Protocol.

ironcontext-core is the pure-CPU, offline-by-default library that powers the sentinel CLI, the Python wrapper and the GitHub Action. It exposes four cohesive subsystems:

• manifest — strict deserializer for MCP initialize / tools/list payloads.
• rules — May 2026 CVE pattern detectors (SEN-001 … SEN-010).
• ris — the Reasoning-Impact Score (0..100 hallucination grade).
• optimizer — heuristic description pruner + pluggable LLM trait.

Everything is glued together by report::Report / scan.

Modules

manifest

Strict deserializer for MCP manifests.

optimizer

Description token-pruning.

report

Top-level orchestrator: glue the parser, rule engine, RIS, and (optionally) the optimizer into one Report.

ris

Reasoning-Impact Score (RIS).

rules

May 2026 CVE pattern pack for MCP manifests.

sarif

Minimal SARIF 2.1.0 emitter.

Enums

SentinelError

Errors surfaced by the library.

Functions

optimize

Convenience: parse + run only the optimizer pass.

scan

Convenience: parse an MCP manifest from raw JSON bytes and produce a full report.
