Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mcp 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 8d 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.

MCP Skill

When to use

Use this skill when:

  • Deciding which MCP tool to use for a task
  • Combining multiple MCP tools in a workflow
  • Troubleshooting MCP tool errors or unexpected results
  • Building commands or skills that reference MCP tools

Procedure: Use MCP tools

  1. Inspect available MCP servers — List configured servers (Sentry, Jira, GitHub, Playwright, Context7, Sequential Thinking) and confirm credentials/permissions for the task.
  2. Pick the right tool per task — Match user intent to the server table below; prefer the most specific tool over generic search.
  3. Chain tools when needed — Apply the Combining tools in workflows patterns; capture intermediate IDs (org slug, project slug, ticket key) before deeper calls.
  4. Verify and handle errors — Apply Error handling and Permission boundaries; confirm the result answers the original question before moving on.

Sentry (augment-partner-remote-mcp-sentry)

Error tracking and performance monitoring.

Tool Purpose When to use
find_organizations Find org slug First call — needed for all other Sentry tools
find_projects Find project slug When filtering by project
find_teams Find team slug/ID Team-based queries
find_releases Recent releases Check deploy timing, release versions
get_issue_details Full issue: stacktrace, tags Investigating a specific error
get_issue_tag_values Distribution by tag Analyzing who/what is affected
get_trace_details Trace overview Performance investigation
get_event_attachment Download attachments Screenshots, logs on events
search_issues List issues by criteria "Show me unresolved errors"
search_events Count/aggregate events "How many errors today?"
search_issue_events Filter events in an issue "Events from last hour"
analyze_issue_with_seer AI root cause analysis When stacktrace alone isn't enough

Key pattern: Always get org slug first → then use other tools. See: sentry-integration skill for investigation workflow.
