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

release-v5-acp 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 9d 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.

Release ACP AI Provider for AI SDK v5

Release @mcpc/acp-ai-provider package for the AI SDK v5 compatibility line (version 0.1.x).

Version Compatibility

ACP Version AI SDK Version Branch
0.2.x v6 main
0.1.x v5 release-v5

When to Use

  • Fix bugs in AI SDK v5 compatibility line
  • Release new 0.1.x versions
  • Backport fixes from main to release-v5

Steps

1. Switch to release-v5 Branch

git checkout release-v5
git pull origin release-v5

2. Apply Fixes (if needed)

Cherry-pick fixes from main:

git cherry-pick <commit-hash>

Or manually apply changes. Note: release-v5 uses AI SDK V2 types (LanguageModelV2StreamPart), main uses V3 (LanguageModelV3StreamPart).

3. Update Version

Edit packages/acp-ai-provider/deno.json:

{
  "version": "0.1.x" // Increment patch version
}

4. Verify Changes

deno fmt packages/acp-ai-provider/
deno check packages/acp-ai-provider/mod.ts
deno test --allow-all packages/acp-ai-provider/tests/

5. Commit

git add packages/acp-ai-provider/deno.json
git commit -m "chore(acp-ai-provider): bump version to 0.1.x"

6. Create and Push Tag

git tag v0.1.x  # Use the new version
git push origin release-v5
git push origin v0.1.x

7. Update Downstream Packages (Optional)

If core or other packages need to use the new version:

  1. Update packages/core/deno.json:

    "@mcpc/acp-ai-provider": "npm:@mcpc-tech/acp-ai-provider@^0.1.x"
    
  2. Bump core version (0.3.x → 0.3.x+1)

  3. Sync all dependent packages to use new core version

  4. Tag core: git tag v0.3.x+1

Key Differences from Main

Aspect release-v5 main
AI SDK V2 V3
Version 0.1.x 0.2.x
Types LanguageModelV2StreamPart LanguageModelV3StreamPart
ACP SDK ^0.4.8 ^0.14.1

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.
