mcporter

Use mcporter to work with MCP servers directly.

Quick start

  • mcporter list
  • mcporter list <server> --schema
  • mcporter call <server.tool> key=value

Call tools

  • Selector: mcporter call linear.list_issues team=ENG limit:5
  • Function syntax: mcporter call "linear.create_issue(title: \"Bug\")"
  • Full URL: mcporter call https://api.example.com/mcp.fetch url:https://example.com
  • Stdio: mcporter call --stdio "bun run ./server.ts" scrape url=https://example.com
  • JSON payload: mcporter call <server.tool> --args '{"limit":5}'

Auth + config

  • OAuth: mcporter auth <server | url> [--reset]
  • Config: mcporter config list|get|add|remove|import|login|logout

Daemon

  • mcporter daemon start|status|stop|restart

Codegen

  • CLI: mcporter generate-cli --server <name> or --command <url>
  • Inspect: mcporter inspect-cli <path> [--json]
  • TS: mcporter emit-ts <server> --mode client|types

Notes

  • Config default: ./config/mcporter.json (override with --config).
  • Prefer --output json for machine-readable results.

Trustgrade A

  • passBody integrity

    Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.

  • passType matchnot applicable to this artifact type

    Whether the artifact is really the kind of thing its metadata claims it is.

  • passFreshness

    How long since the source repository was last pushed to.

  • passPrompt injection

    Scans the artifact's own text for instructions aimed at your agent rather than at you.

  • passLicense

    Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

  • Aevery check passed
  • Bone warning
  • Ctwo warnings
  • Dprompt injection or body integrity failed, or three warnings
  • Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged โ€” not that the artifact is safe.
