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 | $0.00309 | $0.00309 |
| Opus 5 | $0.00154 | $0.00154 |
| Sonnet 5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
sablier-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 12d 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.
What it actually says
Sablier MCP Server — Instructions for Claude
PyPI Versioning
Version is in pyproject.toml. CI auto-publishes to PyPI on push to main — but only if the version changed (duplicates are silently skipped).
When to bump the version: Only when changes affect the local/stdio experience (new tools, tool changes, bug fixes, dependency changes). Cloud Run-only changes (auth, remote transport, deployment config) don't need a PyPI bump.
How to bump:
- Patch (0.2.1 → 0.2.2): bug fixes, small tool tweaks, description changes
- Minor (0.2.2 → 0.3.0): new tools added, tools removed, breaking parameter changes
- Major (0.x → 1.0.0): first stable release (not yet)
If unsure, use patch. Don't bump on every push — only when the change is user-facing for uvx sablier-mcp users.
Transport Modes
- stdio (local): auto-selected when
SABLIER_API_KEYenv var is set. No auth server needed. - streamable-http (Cloud Run): default when no API key. Uses OAuth 2.0, stateless sessions.
Branches
main= production Cloud Run + PyPI publishdev= staging Cloud Run (keep in sync with main)
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.
