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 | $0.03580 | $0.03580 |
| Opus 5.5 | $0.01432 | $0.01432 |
| Sonnet 5.5 | $0.00716 | $0.00716 |
| Haiku 4.5 | $0.00358 | $0.00358 |
Grade A, and why
edge-browser-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 2mo 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 — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI agents and human contributors working on edge-history-mcp. Read this before making changes; it captures the architecture, conventions, design decisions, and the build/test workflow.
What this project is
A stdio Model Context Protocol (MCP) server, written in Python, that exposes Microsoft Edge browsing history to MCP clients. It provides three tools:
list_profiles()— list Edge browsing profiles (friendly names).get_history(profile, date, start_time=None, end_time=None, limit=10000, offset=0)— a paginated page of per-visit history entries for one profile on one day, with an optional intra-day time window.get_history_summary(profile, date, start_time=None, end_time=None, group_by="hour", limit=10000, offset=0)— a privacy-preserving, domain-only aggregation of the same window, bucketed by local hour (no full URLs, query strings or fragments;http/httpsonly).
It is read-only with respect to Edge's data and targets Windows + Edge.
Tech stack & conventions
- Language: Python,
requires-python = ">=3.12". Uses modern typing (X | None,list[...]) andfrom __future__ import annotations. - Package/run tool: uv (Astral). Always use
uv—uv run,uv sync,uv add. Do not callpip/pythondirectly or hand-manage a venv. - MCP framework: official MCP Python SDK, FastMCP (
mcp[cli]). Tools are plain functions decorated with@mcp.tool(); FastMCP derives the JSON schema from type hints and the docstring (Args section matters — it surfaces to clients). - Build backend:
uv_build. Console script entry pointedge-history-mcp = "edge_history_mcp.server:main". - Style: Comment only where clarification helps; rely on docstrings for the public API. Module-level docstrings explain the "why". Keep functions small and pure where possible (conversions are pure and unit-tested directly).
- Errors: Raise
EdgeHistoryErrorfor all expected, user-facing failures (unknown profile, bad date, unreadable DB). The server layer convertsEdgeHistoryErrortoValueErrorso FastMCP returns a clean tool error instead of leaking internals/tracebacks. Never let rawsqlite3/OSErrorescapeedge.py.
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.
