What is conduit_mcp CLAUDE.md?

Repository guidance for Claude Code when working on ConduitMCP, an Elixir library for building Model Context Protocol (MCP) servers that connect tools and data to AI applications.

Building, testing, formatting, linting, analyzing, documenting, benchmarking, and checking code coverage for ConduitMCP.

It puts the project overview, architecture, request flow, and standard development commands in one place, so an agent can work consistently in the repository.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02352	$0.02352
Opus 5	$0.01176	$0.01176
Sonnet 5	$0.00470	$0.00470

Security

Grade A, and why

conduit_mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

ConduitMCP is an Elixir library implementing the Model Context Protocol (MCP) specification (version 2025-06-18). It lets developers build MCP servers that expose tools, resources, and prompts to LLM applications like Claude Desktop and VS Code. The library is published on Hex as conduit_mcp.

Build & Test Commands

mix test test/conduit_mcp/dsl_test.exs:42        # Run a specific test line
mix format                # Format code

Requires Elixir ~> 1.18. No config directory exists; validation config is set via Application.put_env(:conduit_mcp, :validation, [...]) in tests or application config.

Architecture

MCP server modules are stateless — just compiled functions. Each HTTP request runs in its own Bandit process for maximum concurrency. Rate limiting uses a user-supplied Hammer module.

The library itself does start a supervision tree (ConduitMcp.Application, mod: in mix.exs). It is deliberately small: it owns the long-lived ETS tables that must outlive short-lived request processes, plus the session janitor.

Always: ConduitMcp.Cancellation.Owner, ConduitMcp.Session.EtsStore.Owner, ConduitMcp.Transport.SSE.Owner, ConduitMcp.Session.Janitor (as ConduitMcp.Session.Janitor.Default; disable with config :conduit_mcp, :session_janitor, false), and a second ConduitMcp.Session.Janitor sweeping the cancellation table (as ConduitMcp.Cancellation.Janitor; disable with config :conduit_mcp, :cancellation_janitor, false).
Conditionally: ConduitMcp.Tasks.EtsStore.Owner (default tasks store only), ConduitMcp.OAuth.KeyProvider.JWKS.Owner (only when Req is compiled in).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

conduit_mcp CLAUDE.md is an instructions file published in the GitHub repository nyo16/conduit_mcp (9 stars, last pushed 13d ago), licensed Apache-2.0. It adds 2,352 tokens to every session, about $0.0118 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
