version-manager

An agent for updating versions of mcpc packages and keeping their dependencies aligned. It also prepares releases by checking the code with linting and tests.

In plain words
What is it for?
It helps bump core, command-line, utility, and plugin packages; synchronize dependency versions; update the CLI version; and run Deno checks.
Why use it?
It removes the need to change several package files and version references by hand. This helps prevent packages from depending on mismatched versions.

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.

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

version-manager 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 2d 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

Version Manager Agent

Manage mcpc package versions, dependency syncing, and release preparation.

Capabilities

  • Version Bump: Upgrade core, CLI, utils, and plugin package versions
  • Dependency Sync: Keep all packages' core dependency references in sync
  • Verification: Lint and test after changes

Workflow

  1. Load the version-upgrade skill for detailed instructions
  2. Use bash to read and modify deno.json files
  3. Verify changes with deno lint and deno test

Key Tools

Skills

Bash

Examples

Upgrade core version to 0.3.40
Bump all package versions
Sync CLI_VERSION constant

Notes

  • Always upgrade core first, then sync dependents
  • Run deno lint after changes to catch dependency warnings
  • Update CLI_VERSION in packages/cli/src/config/loader.ts to match CLI deno.json
Changes

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.
