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 | $0.02821 | $0.02821 |
| Opus 5 | $0.01411 | $0.01411 |
| Sonnet 5 | $0.00564 | $0.00564 |
| Haiku 4.5 | $0.00282 | $0.00282 |
Grade A, and why
mcp-server-manager 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 10d 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.
How it starts

Build & Test Commands
cargo build --workspace # Debug build (all crates)
cargo build --release -p mcpsm-cli # Release CLI binary
cargo build --release -p mcpsm-gui # Release GUI binary
cargo run -p mcpsm-cli # Run headless CLI daemon
cargo run -p mcpsm-gui # Run macOS GUI app
cargo test --workspace # Run all 9 unit tests
cargo test -p mcpsm-core config # Run config tests only
cargo test -p mcpsm-core log_buffer # Run log buffer tests only
cargo test -p mcpsm-core templates # Run template tests only
./scripts/build-app.sh # Build MCPSM.app bundle (release, uses mcpsm-gui)
./scripts/generate-icons.sh # Regenerate status bar PNGs + .icns from SVGs
Architecture
Cargo workspace with three crates:
mcpsm-core(library) — all business logic, shared by both binariesmcpsm-cli(binary:mcpsm) — headless CLI daemon, tokio runtime on main threadmcpsm-gui(binary:mcpsm-gui) — macOS status bar app, two-thread design
Two-thread design (GUI only) with a channel bridge:
- Main thread: AppKit status bar (NSStatusItem via objc2)
- Background thread: tokio async runtime via
mcpsm_core::runtime::run_backend()
Communication:
- Web/GUI → Backend:
tokio::sync::mpsc::unbounded_channel<AppCommand> - Backend → Web:
tokio::sync::broadcast::channel<BackendEvent>(SSE streaming) - Shared state:
Arc<RwLock<HashMap<String, ServerInfo>>>for web layer reads - Shared MCP clients:
Arc<RwLock<HashMap<String, Arc<McpClient>>>>for proxy access - Tool changes:
tokio::sync::watch::channel<()>signals proxy when tool lists change - Config watcher:
notifycrate on a dedicated std::thread, sendsReloadConfigIfChangedthrough cmd channel
The bridge contract lives in crates/mcpsm-core/src/bridge/commands.rs — all interaction goes through AppCommand and BackendEvent enums.
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.
