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 | $0.00254 | $0.00254 |
| Opus 5.5 | $0.00102 | $0.00102 |
| Sonnet 5.5 | $0.00051 | $0.00051 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
seq-mcp seq-mcp-server.instructions.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.
What it actually says
Seq MCP Server Instructions
Goal
Build and maintain an MCP server that enables AI agents to safely query and inspect data from Datalust Seq and its OpenTelemetry-backed events.
Design Requirements
- Define MCP tools with strict schemas and clear intent boundaries.
- Keep tool responses concise, structured, and deterministic when possible.
- Prevent unbounded or unsafe queries through input validation, limits, and defaults.
- Implement robust error mapping so agent clients receive actionable failures.
Seq Integration Requirements
- Keep Seq endpoint and API credentials externalized in configuration.
- Use least-privilege access patterns for Seq API keys.
- Sanitize and validate all user/agent-provided filters or query fragments.
- Apply paging/time-window constraints by default to avoid excessive data pulls.
Container Requirements
- Ensure the service runs cleanly as a containerized workload.
- Expose configuration through environment variables.
- Keep image/runtime surface minimal and secure.
Quality Bar
- Prioritize correctness, security, and contract clarity.
- Keep naming and module boundaries straightforward.
- Add/update tests for parsing, validation, and Seq client behavior when code exists.
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.

seq-mcp seq-mcp-server.instructions.md is an instructions file published in the GitHub repository MCLifeLeader/seq-mcp (3 stars, last pushed 10d ago), licensed MIT. It adds 254 tokens to every session, about $0.0010 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.
