Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01725 | $0.01725 |
| Opus 5 | $0.00863 | $0.00863 |
| Sonnet 5 | $0.00345 | $0.00345 |
| Haiku 4.5 | $0.00172 | $0.00172 |
Grade A, and why
forge-mcp AGENTS.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 3d 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

forge-mcp — Agent Guide
What this repo is
forge-mcp is a pre-implementation MCP server project. Only design docs and reference files exist until milestones land — no runnable source yet.
README.md— architecture overview, tool surface, guaranteesimplementation_plan.md— the source of truth: LLM-executable build plan (M0–M7), gates, rollbacksreference_files/— nav-mcp source to port (READ-ONLY; never edit)forge.example.json— config template (liveforge.jsonis gitignored)
Target runtime & locations
- Language: TypeScript (strict) · Runtime: Bun ≥ 1.3.x — not Node · OS: Windows 11, PowerShell 7
- Code root: this repo. All source is committed here.
- Runtime state:
%LOCALAPPDATA%\forge-mcp\—daemon.json(contains the bearer token),boot.lock,logs/. Never in the repo. Ifdaemon.jsonever appears under the repo root, that is a bug (and a secret leak) — stop and fix.
Key constraints (from implementation_plan.md §0)
| Constraint | Detail |
|---|---|
bun build --compile |
BANNED — run TS source directly (SDK subpath-export issues) |
| Dependencies | EXACT pins only. No ^/~. bun.lock committed. Manual bumps. Re-run M0 spike after any Bun bump. |
| Never-throw | Every tool returns a NavEnvelope (ok:false on error; transport never sees exceptions) |
reference_files/ |
Read-only port source. Live nav-mcp install untouched until M7 cutover. |
opencode.json |
NEVER modified by agent. Snippets delivered for manual user apply. |
| Security floor | 127.0.0.1 bind · bearer token · Origin validation/403 · .env* guard · canonical+realpath path jail · cmd-shim metachar gate |
| Invalidation authority | Fingerprints (mtime-in-key) = correctness. Watcher events = eviction accelerator only. |
| Fallback floor | Worst case == nav-mcp parity (embedded mode, stat invalidation, CLI/ripgrep ast). Below that = build failure. |
Build order (sequential, gated — do not skip)
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.

forge-mcp AGENTS.md is an instructions file published in the GitHub repository fuwadog/forge-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 1,725 tokens to every session, about $0.0086 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.
