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: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency87
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to christianclaudio/mcp-server-taxcode). View diagnostics → Pass
  • License check failed: no license is declared. See how to fix → Fail
  • Actively maintained (last published 0 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability0
  • Schema quality not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to assess.Unverified
Stability & Change Management0
  • Stability not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to compare.Unverified
Tool Coverage0
  • Tool coverage not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool definitions to assess.Unverified
Tool Safety0
  • Tool safety not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool text to scan.Unverified
Capabilities0
  • Protocol version not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we never saw its MCP handshake.Unverified

Unverified: 6 categories

Categories scored 0 because we could not verify them: 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.

MCP tools

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 →

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.

Install

How do I install the io.github.christianclaudio/taxcode MCP server?

io.github.christianclaudio/taxcode runs locally as a container image, launched with docker run --rm -i -e TAXCODE_API_KEY -e TAXCODE_BASE_URL -e TAXCODE_MCP_PROFILE -e TAXCODE_MCP_READONLY ghcr.io/christianclaudio/mcp-server-taxcode:0.7.2. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

# add to Claude Code
claude mcp add christianclaudio-taxcode -- docker run --rm -i -e TAXCODE_API_KEY -e TAXCODE_BASE_URL -e TAXCODE_MCP_PROFILE -e TAXCODE_MCP_READONLY ghcr.io/christianclaudio/mcp-server-taxcode:0.7.2

This image reads TAXCODE_API_KEY, TAXCODE_BASE_URL, TAXCODE_MCP_PROFILE and TAXCODE_MCP_READONLY. Set them in your client's env block for this server; docker run -e passes each one through to the container.
