+**code-reason** is an MCP server that gives coding agents real program-analysis primitives — data-flow reachability, call-graph traversal, evidence-chain construction — so they verify code behavior from ground truth instead of speculation.
+
+## Why code-reason
 
 Coding agents are good at reading code, but they struggle with whole-program questions:

 - *Who really invokes this function across the codebase?*
 - *What is the complete evidence chain from source to sink?*
 
-These are program-analysis questions. Answering them with grep-and-guess, or with ever-larger context windows, scales poorly and produces false confidence. They are better answered with a code property graph and a few well-chosen graph queries — exposed as MCP tools the agent drives directly.
+Without a code-analysis tool, the agent answers these by **manual grep-based tracing.** It can read code, but it can't actually trace data flow, walk a control graph, or verify that user input reaches a sink. Ask any modern coding agent how it traces taint without a tool, and the answer is some variant of *"I read files and follow string matches."*
+
+That works for simple cases. The cracks show on anything non-trivial — aliased variables, inter-procedural flow, sanitization checks, framework-injected inputs. The agent still produces an answer, often with high confidence, but it's reading 6+ files to confirm a single chain, burning context on speculation, and silently missing flows it never thought to grep for. For security-sensitive work, a confident wrong answer is more dangerous than no answer at all — and that's exactly what grep-based tracing produces at scale.
+
+code-reason closes the gap. The agent stays in charge of *what's interesting*; code-reason answers *what's actually true* — backed by a code property graph parsed once and queried cheaply. The result: agents that are more deterministic, more token-efficient, and faster — and agentic security workflows you can actually trust.
+
+Where traditional SAST tools produce findings reports for humans to triage, code-reason exposes the underlying analysis primitives for an agent to drive its own investigation.

+Built on [Fraunhofer AISEC's Code Property Graph](https://github.com/Fraunhofer-AISEC/cpg) for multi-language data-flow, control-flow, and taint analysis, and the [Kotlin MCP SDK](https://github.com/modelcontextprotocol/kotlin-sdk) to expose those capabilities as agent-callable tools.

+## What you get
 
-**Tech stack.** code-reason uses [Fraunhofer AISEC's Code Property Graph](https://github.com/Fraunhofer-AISEC/cpg) for multi-language data-flow, control-flow, and taint analysis, and the [Kotlin MCP SDK](https://github.com/modelcontextprotocol/kotlin-sdk) to expose those capabilities as agent-callable tools.
+From dogfood sessions on real Java and Python codebases:
 
-**Long-term vision.** Make program-analysis primitives a first-class capability for coding agents — sharpening vulnerability detection precision, eliminating tokens wasted on speculative grep-and-guess exploration, and turning vulnerability hunting into a directed, evidence-driven workflow.
+- **30-40% fewer agent tokens** on multi-step security reviews, mostly from call-graph queries that would otherwise take 5-10 grep iterations to confirm by hand.
+- **Compact structured answers, not file dumps.** A call-graph query returns reachable methods in JSON; the grep-and-read equivalent forces the agent to read 6+ files to confirm one chain.
+- **One analysis pass per service, unlimited queries.** `reason_analyze_project` builds the CPG once; every other `reason_*` tool queries it cheaply.
+- **Real evidence chains.** `reason_trace_taint_path` returns the full source-to-sink path with intermediate steps and code context — not "looks like SQLi maybe."

+
+The marquee value is the **navigation** and **data flow** primitives — the agent composes them to answer whole-program questions on its own. The **catalog scan** tools are a convenience baseline for quick first-pass triage; the agent's own reasoning over the primitives is what makes the difference on real codebases.
