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 Security100

Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "memory_delete" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail

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 →

What is the io.github.Mibayy/token-savior MCP server?
io.github.Mibayy/token-savior is an MCP server listed in the public MCP registry as io.github.Mibayy/token-savior. Structural codebase MCP server with persistent memory: navigate by symbol, recall across sessions. This page covers its PyPI package (token-savior-recall).
Is the io.github.Mibayy/token-savior MCP server safe to use?
io.github.Mibayy/token-savior scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 November 2026. 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 io.github.Mibayy/token-savior MCP server expose?
io.github.Mibayy/token-savior exposes 69 tools: list_projects, switch_project, get_git_status, get_changed_symbols, build_commit_summary, and 64 more. Their descriptions and schemas cost roughly 6,320 tokens of context every time the server is loaded.
Is the io.github.Mibayy/token-savior MCP server still maintained?
io.github.Mibayy/token-savior is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the io.github.Mibayy/token-savior MCP server under?
io.github.Mibayy/token-savior declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the io.github.Mibayy/token-savior MCP server?
VerifyMCP ran 16 checks on io.github.Mibayy/token-savior, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
