Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.01002 |
| Opus 5.5 | $0.00016 | $0.00401 |
| Sonnet 5.5 | $0.00008 | $0.00200 |
| Haiku 4.5 | $0.00004 | $0.00100 |
Grade A, and why
mcp-server-operations 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Operate an MCP Server
Everything after the server works on your machine.
Distribution
How people get it determines how they upgrade it.
| Shape | Install | Upgrade path |
|---|---|---|
| npm / PyPI / NuGet package | Registry install, pinned version | User bumps the pin |
| Repository + local build | Clone and build | User pulls |
| Container image | Pull a tag | Retag and repull |
| Bundled in a plugin | Arrives with the plugin | Plugin release |
Publishing to a registry is the only shape where a consumer can pin a version and know what they are running. A server installed from a branch is a server whose behaviour changes without anyone deciding it should.
Versioning
A tool signature is an API. Agents bind to names and schemas, and prompts written against your tools are code you do not control.
Breaking, needs a major version:
- Removing a tool, or renaming one
- Removing a parameter, or making an optional one required
- Narrowing an accepted value range
- Changing the shape of a returned payload consumers parse
Not breaking:
- Adding a tool
- Adding an optional parameter
- Widening an accepted range
- Improving a description
That last one deserves emphasis: descriptions are the agent's interface, and improving them is both safe and the highest-leverage change you can ship. Most "the server got worse" reports are a description that drifted vaguer.
Keep a changelog a consumer can read before upgrading. "Various improvements" tells someone running it in production nothing.
Deployment Shapes
| Transport | Where it runs | Operational burden |
|---|---|---|
| stdio | On the user's machine, launched by the host | None — the host owns the lifecycle |
| HTTP | A service you deploy | Everything: uptime, scaling, certificates, auth |
Choosing HTTP means signing up to run a service. Choose it when the server must be reachable by many users or hold central state — not because it felt more modern.
For HTTP, prefer stateless sessions. Stateless servers scale horizontally and survive restarts without coordination; stateful ones need session affinity, which is a load-balancer problem you inherit forever.
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.

mcp-server-operations is a skill published in the GitHub repository fabioc-aloha/Alex_Skill_Mall (5 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 1,002 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 2026-09-14.

windows-image-updater
Automates Windows container image migration for OneBranch pipelines. Bumps AdoPipelineGeneration package, regenerates pipeline configs via ConfigGen, and verifies old image reference is removed. Use for LTSC2019 to LTSC2022 migration, container image updates, OneBranch pipeline image upgrades.
infra-ci-cd-docker
Docker containerization patterns for Node.js/TypeScript development and production.
apply-change-leadership
Use when a manager's team is experiencing a significant organizational change — restructuring, strategy shift, leadership change, layoffs, or major process transition — and needs leadership that maintains team stability, preserves trust, and converts uncertainty into direction.
apply-cross-functional-leadership
Use when a manager needs to lead a project or initiative that depends on team members or stakeholders they do not formally manage — to build voluntary cooperation, alignment, and momentum across organizational boundaries through influence rather than authority.
apply-distributed-team-practices
Use when managing a team where members work in different locations, time zones, or on hybrid schedules — to adapt management practices so remote members have equal access to information, relationships, and advancement opportunities as in-office members.
apply-grow-coaching
Use when a manager wants to help a direct report solve a problem, develop a skill, or reach a goal through structured questioning rather than advice-giving — because telling people answers builds dependency while coaching builds self-sufficiency.
