How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 6 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 426 tokens (~142/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

Background: How many MCP packages publish verified provenance →
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_budget Check whether there is usage budget left ~156
Checks if a provider is below a usage threshold, so you can decide whether to start a long or expensive task now or postpone it until the limit resets. Without `window`, checks every window and reports the tightest one. Returns ok, usedNow, resetsInSeconds and advice.
| Name | Type | Req | Description |
|---|---|---|---|
| max_percent | number | – | Budget threshold in percent (default 80). ok = usedNow < max_percent. |
| provider | string | yes | Provider id, e.g. "claude" or "codex". |
| window | string | – | Limit window: "5h" (short window, the first) or "7d" (long window, the second). Labels like "1d" or "30d" also work. |
No output schema declared.
No examples provided.
get_usage Get AI usage limits ~114
Current usage of AI subscription limits (Claude Code, Codex, GitHub Copilot, Windsurf and any AI the user added to TokenBar). For each AI: windows (usually 5h and 7d) with usedNow (% used right now, 0 after the reset time), resetsAt (unix s) and resetsInSeconds.
| Name | Type | Req | Description |
|---|---|---|---|
| provider | string | – | Optional provider id: "claude", "codex", "copilot", "windsurf" or another id. Omit for all. |
No output schema declared.
No examples provided.
time_until_reset Time until a usage limit resets ~99
Seconds (and human text) until a provider's usage window resets. Default window: the first (5h).
| Name | Type | Req | Description |
|---|---|---|---|
| provider | string | yes | Provider id, e.g. "claude" or "codex". |
| window | string | – | Limit window: "5h" (short window, the first) or "7d" (long window, the second). Labels like "1d" or "30d" also work. |
No output schema declared.
No examples provided.
How do I install the TokenBar MCP server?
TokenBar ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 3832d2a22db011858c8492aa3ab3083952abaf0d80e64887d7c4daa670a28c57; the commands to do that are on this page. If it does not match, do not open it.

What is the TokenBar MCP server?
TokenBar is an MCP server listed in the public MCP registry as io.github.ChaconLucas/tokenbar. AI usage limits (Claude Code, Codex, Copilot, Windsurf): check budget and time until reset. This page covers its MCPB bundle (https://github.com/ChaconLucas/tokenbar/releases/download/v0.5.3/TokenBar.mcpb).
Is the TokenBar MCP server safe to use?
TokenBar scores 43 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the TokenBar MCP server expose?
TokenBar exposes 3 tools: get_usage, time_until_reset, check_budget. Their descriptions and schemas cost roughly 369 tokens of context every time the server is loaded.
What licence is the TokenBar MCP server under?
TokenBar declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
