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 | $0.00864 | $0.00864 |
| Opus 5 | $0.00432 | $0.00432 |
| Sonnet 5 | $0.00173 | $0.00173 |
| Haiku 4.5 | $0.00086 | $0.00086 |
Grade A, and why
pararam-nexus-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 11d 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.

Architecture
UV workspace monorepo with two independent PyPI packages. Python 3.14+, fully async.
Package: pararam-nexus-mcp (packages/pararam-nexus-mcp/)
FastMCP server providing tools for pararam.io (messaging/collaboration platform).
Entry point: server.py creates FastMCP instance, registers tools from three modules, runs server on stdio transport.
Client: client.py — singleton PararamClient wrapping AsyncPararamio. In full mode it uses cookie-based session persistence + optional TOTP 2FA; in limited mode it passes user_token= through to AsyncPararamio and the cookie manager is never created.
Config: config.py — Pydantic BaseSettings loading from .env. Either set PARARAM_LOGIN/PARARAM_PASSWORD (+ optional PARARAM_2FA_KEY/PARARAM_COOKIE_FILE) for full mode, or set PARARAM_USER_TOKEN for limited mode. The two sets are mutually exclusive; Config.validate_credentials() enforces XOR.
Modes:
full(default) — every registered tool is available.limited(set whenPARARAM_USER_TOKENis present) — the server prunes its tool list to the allow-list defined asLIMITED_MODE_TOOLSinserver.py. User tools (users.py) aren't registered at all in limited mode.
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.
