How Do AI Agents Spend Your Money? (And How Synapse MCP Saves It)

A research paper reveals agentic coding tasks consume 1,000x more tokens than standard code reasoning. We break down why — and how Synapse MCP's precision retrieval, AST outliner, and SmartCrusher tackle each root cause.

Why LLMs Code Better with Knowledge Graphs — AST vs. Grep for Frontier AI Agents

Real data from our R&D: How replacing blind grep/read loops with AST-backed caller/callee graphs saves 30-60% of context tokens, eliminates false confidence, and solves multi-app refactoring.

How Local Code Knowledge Graphs Work — Inside the Microsecond BEAM Engine

How Synapse MCP uses ETS, GenServer-per-repo supervision, pure Elixir BM25F embeddings, and in-memory Shadow Graph safe writes to give AI agents microsecond codebase context on the BEAM.

Benchmarks

We Ran a Three-Arm Benchmark. We Lost On Per-Query Tokens. Here's Why We Still Win.

We installed shell tools, Synapse MCP, and codebase-memory-mcp on the same machine, indexed the same codebase, and ran five identical queries. We lost on per-query token count. We're publishing the results anyway — here's why total session cost is what matters.

Synapse MCP vs. Graphify — A Live Head-to-Head Benchmark

We installed both tools on the same machine, indexed the same codebases, and ran the same queries — including the Linux kernel. Synapse is faster, leaner, and safer across every dimension. Full results, raw timing, token counts.

Karpathy's LLM Wiki vs. Synapse MCP: Why Code Needs a Graph, Not Prose

Andrej Karpathy's LLM Wiki gist is brilliant for prose —but code isn't prose. Applied to a codebase,the wiki pattern collides with a live, structured artifact. Here's where a persistent code graph — not a folder of summaries — is the right tool,and the honest reasoning behind every trade-off.
