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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.04042 |
| Opus 5.5 | $0.00022 | $0.01617 |
| Sonnet 5.5 | $0.00011 | $0.00808 |
| Haiku 4.5 | $0.00006 | $0.00404 |
Grade A, and why
upgrade-maintenance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Upgrade Maintenance
Perform a full upgrade maintenance pass on the lfx-mcp codebase. This covers three sequential phases: dependency upgrades, upstream contract fixes, and a query service argument review.
Phase 1 — Upgrade all dependencies
Step 1.1 — Upgrade the Go toolchain version
Compare the local toolchain version against the go directive in go.mod and
update if the local toolchain is newer:
# Extract the version from the local toolchain (e.g. "go1.24.3").
LOCAL=$(go version | awk '{print $3}') # e.g. go1.24.3
GOMOD=$(grep '^go ' go.mod | awk '{print $2}') # e.g. 1.23.0
echo "Local toolchain: $LOCAL"
echo "go.mod go directive: $GOMOD"
If the local toolchain is newer, update go.mod:
# Updates the go directive to match the local toolchain.
go mod tidy -go=${LOCAL#go}
Also update any other files that pin the Go version:
Dockerfile—FROM golang:X.Y.ZorFROM golang:X.Y-alpinebase image..github/workflows/*.yml—go-version:fields in GitHub Actions steps.Makefile— any hardcodedGO_VERSIONvariable.AGENTS.md/README.md— version references in prerequisite tables.
After updating, verify the build still compiles with the new toolchain:
make build
If any deprecated language features or removed stdlib symbols cause errors, fix them before continuing.
Step 1.2 — Upgrade Go module dependencies
# Upgrade all direct dependencies to their latest minor/patch versions.
go get -u ./...
# Tidy the module graph (removes unused indirect deps, syncs go.sum).
go mod tidy
After running, inspect go.mod for version changes. The most impactful upgrades
to watch are the github.com/linuxfoundation/lfx-v2-* packages — they
regularly add, rename, or remove Goa-generated struct fields, which directly
affects tool handler code in internal/tools/ and client wiring in
internal/lfxv2/client.go. Phase 2 is the step that reviews these changes; if
any lfx-v2-* bump lands without a same-session Phase 2 pass (e.g. it was
folded into a larger commit, or maintenance was interrupted), re-run Phase 2
retroactively against that commit — see "Finding OLD and NEW" in Step 2.1.
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.

upgrade-maintenance is a skill published in the GitHub repository linuxfoundation/lfx-mcp (21 stars, last pushed 6d ago), licensed MIT. It adds 56 tokens to every session and 4,042 once invoked, about $0.0002 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 2026-08-30.
