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 | $0.02932 | $0.02932 |
| Opus 5.5 | $0.01173 | $0.01173 |
| Sonnet 5.5 | $0.00586 | $0.00586 |
| Haiku 4.5 | $0.00293 | $0.00293 |
Grade A, and why
oculo 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 1mo 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
The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architecture
MCP Transport (HTTP, not stdio)
Electron's <webview> is only accessible from the renderer process, so we use HTTP:
Claude Code → bin/oculo-mcp.mjs (stdio bridge) → HTTP POST :19516/mcp
→ McpServerManager (main) → IPC 'mcp:tool-call' → Renderer → webview.executeJavaScript()
→ IPC 'mcp:tool-result' → HTTP response → stdio bridge → Claude Code
- Electron app starts HTTP server on ports 19516-19520, writes
~/.oculo-port(port:authtoken) bin/oculo-mcp.mjsis the stdio MCP bridge that Claude Code connects to — it reads~/.oculo-portand proxies
Register with Claude Code
claude mcp add oculo -- node ~/Desktop/oculo/bin/oculo-mcp.mjs
Tools are always discoverable (static definitions in bridge), but Oculo must be running for tool calls to succeed.
Minimal prompts (recommended)
claude mcp add oculo --allow-all -- node ~/Desktop/oculo/bin/oculo-mcp.mjs
This lets Claude use Oculo tools without per-call approval prompts. Combined with Autonomous Mode (Settings → Autonomous Mode), this gives zero-friction browser automation.

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.

oculo CLAUDE.md is an instructions file published in the GitHub repository xidik12/oculo (5 stars, last pushed 3mo ago), licensed MIT. It adds 2,932 tokens to every session, about $0.0117 per session on Opus 5.5. 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.
