What it does
Mcporter is an agent skill from trpc-group/trpc-agent-go. Use the mcporter CLI to list, configure, auth, and call MCP servers/tools directly (HTTP or stdio), including ad-hoc servers, config edits, CLI/type generation, and MCP-backed skills that need a durable command path.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: A Go framework for building production agent systems with graph workflows, tools, memory, A2A, AG-UI, MCP, evaluation, and observability. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/mcporter”
What it can do on your machine
Read from SKILL.md and the folder at commit 9bb1c42. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mcporter loads about 1k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 444 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

mcporter
Use mcporter to work with MCP servers directly.
In OpenClaw, treat mcporter as the execution substrate for MCP-backed
skills. When a user wants to keep an MCP capability for future work, prefer
creating or updating a skill that describes when to use the capability and
stores the repeatable mcporter command path. Do not create a separate runtime
registry when a skill can carry the durable behavior.
Skill-first MCP shape
SKILL.md: triggers, workflow, constraints, examples, and recovery steps.mcp.json: mcporter-native server config when the skill needs a dedicated server definition.references/: schemas, API notes, or longer operation guides.scripts/: wrappers for fragile multi-step calls or post-processing.
Credential handling
- Keep shared, bundled, published, or repo-tracked skills free of raw secrets. Reference environment variables, token helper commands, OAuth login state, runtime config, or platform-managed credentials instead.
- If the user explicitly provides a complete private MCP config or a
credential-bearing endpoint and asks to keep or use it, save it in a local
private config file such as skill-local
mcp.jsonin a writable user-managed skill root, or a dedicated user-managed private mcporter config file. Keep it non-shared and excluded from source control and packaging. Set file permissions to0600when possible. Do not ask the user to re-enter the same value as an environment variable, and do not edit shell startup or trusted env files just to persist it. Do not echo the secret value back in CLI output, logs, or errors; redact or omit token and secret fields from displayed tool results. - For bot-global OpenClaw MCP capabilities, prefer a local skill plus
skill-local
mcp.json. Usemcporter --config path/to/skill/mcp.json ...as the durable command path. Treat~/.mcporter/mcporter.jsonas an interoperability copy when useful, not as the capability boundary. The credential-bearing source of truth for a durable skill run is the explicit--configfile you pass.

For a durable MCP skill, first inspect the server schema:
mcporter --config path/to/skill/mcp.json list <server> --schema --output jsonThen call the selected tool with explicit arguments:
mcporter --config path/to/skill/mcp.json call <server.tool> key=valueQuick start
mcporter listmcporter list <server> --schemamcporter 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
- Prefer explicit
--configfor skills. mcporter can also use its default project or user config paths for local ad-hoc CLI work, but shared or packaged skills and automation should always pass an explicit--config. - Prefer
--output jsonfor machine-readable results.

When should I use Mcporter?
Mcporter fits situations like: tasks that involve MCP servers.
How do I install Mcporter in Claude Code?
Run `npx skills add trpc-group/trpc-agent-go --skill mcporter -a claude-code`. Or copy the skill folder (openclaw/skills/mcporter in trpc-group/trpc-agent-go) into .claude/skills/mcporter in your project. Claude Code loads it when a task matches its description.
How do I install Mcporter in Codex?
Run `npx skills add trpc-group/trpc-agent-go --skill mcporter -a codex`. Or copy the skill folder (openclaw/skills/mcporter in trpc-group/trpc-agent-go) into .agents/skills/mcporter in your project. Codex loads it when a task matches its description.
Can I use Mcporter in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add trpc-group/trpc-agent-go --skill mcporter -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mcporter, .gemini/skills/mcporter, .github/skills/mcporter and .opencode/skills/mcporter in your project.
What does Mcporter need to run?
SKILL.md names no scripts, command-line tools or credentials: Mcporter is instructions for the agent only.
Does Mcporter access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Mcporter safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Mcporter use?
Mcporter is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Mcporter use?
About 1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Mcporter?
Skills that share tags, products or a category with Mcporter: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 38k stars) and Fastmcp Client CLI (PrefectHQ/fastmcp, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
