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 | $0.00463 | $0.00463 |
| Opus 5.5 | $0.00185 | $0.00185 |
| Sonnet 5.5 | $0.00093 | $0.00093 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
honeybadger-mcp-server 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 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
Contributor notes
Adding a new MCP tool
Every tool registered with the server must declare, in this order inside
mcp.NewTool(...):
-
mcp.WithTitleAnnotation("Title Case Name")— a short, human-readable title. Required by the Anthropic Connectors Directory; a missing title is an automatic review rejection. -
mcp.WithDescription(...)— what the tool does. -
mcp.WithReadOnlyHintAnnotation(...)andmcp.WithDestructiveHintAnnotation(...)— both are required on every tool. Read-only tools:mcp.WithReadOnlyHintAnnotation(true)/mcp.WithDestructiveHintAnnotation(false). Tools that create, update, or delete:mcp.WithReadOnlyHintAnnotation(false)/mcp.WithDestructiveHintAnnotation(true). -
Delete tools must not delete on the first call. Declare
withConfirmParam(), appendconfirmNoteto the description, and gate the handler ondeletionConfirmed(...); when it returns false, look up the resource and returndeletionPreview(...)so the user sees what will be deleted. Pass the same tool name and ids to both (seehandleDeleteProjectinprojects.go).destructiveHintis only a hint to the client; it doesn't stop the call.TestDeleteToolsRequireConfirmationininternal/hbmcp/confirm_test.gofails for anydelete_*tool that deletes without a valid token or isn't listed in itsdeleteToolArgs.
TestAllToolsHaveTitleAndAnnotations in internal/hbmcp/server_test.go fails
the build if any tool (including hidden aliases) is missing a title,
readOnlyHint, or destructiveHint. Run go test ./... before committing.
Tools live in internal/hbmcp/ grouped by domain (faults.go, alarms.go,
projects.go, dashboards.go, checkins.go, insights.go, streams.go, reference.go)
and are registered from internal/hbmcp/server.go.
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.
