A Claude Code plugin (and a standalone Agent Skill) that runs MentionAgent link building outreach from your agent: review the drafts it wrote, send the batch, answer the publishers who replied, and close placements, without opening the dashboard.
It wraps the MentionAgent MCP server (https://mentionagent.ai/mcp, 35 tools) with a skill that knows the daily loop, which two tools send real email, which two spend credits, and where to stop and ask you.
Works in Claude Code, Cursor, Windsurf, or any MCP client that can set a request header.
Then set your API key in the environment the agent runs in:
The plugin's .mcp.json reads ${MENTIONAGENT_API_KEY}, so the key never lands in a file. Keys are created in the MentionAgent dashboard under Settings, Agent access, and are shown once.
Cursor reads Agent Skills from .cursor/skills/ (project) or ~/.cursor/skills/ (global), and also from .claude/skills/ for compatibility. Copy the skill folder in, then add the server to .cursor/mcp.json:
Type /link-building-outreach in the Agent chat to invoke it. Full walkthrough: https://mentionagent.ai/cursor-seo-skill/
OpenCode reads Agent Skills from .opencode/skills/ (project) or ~/.config/opencode/skills/ (global), and also from .claude/skills/ and .agents/skills/, so a copy installed for Claude Code or Cursor is already visible. Copy the folder in, then add the server as a remote MCP entry in opencode.json and sign in with OAuth (a browser window opens on the MentionAgent consent page):
The permission rules matter: OpenCode defaults to allow and MCP tools are registered as mentionagent_<tool>, so without them the two tools that send email, and redirect_thread, which opens a thread to an address taken from an email, run without a prompt. Never start OpenCode with --auto in a project that has this server enabled. To use an API key instead of OAuth, set "oauth": false on the server and add "headers": { "Authorization": "Bearer {env:MENTIONAGENT_API_KEY}" } (OpenCode's substitution syntax is {env:NAME}, not ${env:NAME}). There is no slash command: ask the agent what is waiting on MentionAgent and it loads the skill through its skill tool. Full walkthrough: https://mentionagent.ai/opencode-seo-skill/
OpenClaw reads Agent Skills from <workspace>/skills/ and ~/.agents/skills/ (the SKILL.md can sit up to six folders deep). Install the folder, register the server, sign in with OAuth (a browser window opens on the MentionAgent consent page), then probe:
To use an API key instead of OAuth, drop --auth oauth and pass --header "Authorization=Bearer ma_live_..." (the flag takes KEY=VALUE; a colon is rejected). openclaw mcp doctor will then flag the literal token, which is the reason to prefer OAuth on a shared Gateway. The skill answers to /link-building-outreach in any connected channel. Full walkthrough: https://mentionagent.ai/openclaw-seo-skill/
Copy skills/link-building-outreach/ into ~/.claude/skills/ (personal) or .claude/skills/ in a project, then connect the MCP server yourself:
Or, in any client that takes a JSON config:
Ask your agent: "Connect to MentionAgent and show me what is waiting." It calls get_status, lists your sites, and tells you what it can and cannot do on your behalf.
The 35 published tools and nothing else. It cannot see mailbox credentials, billing, domain transfer or account deletion; those stay behind a login. Two tools send email (approve_batch, send_reply) and both are written to be shown to you first. send_reply has no recipient field: the address comes from the thread. The one tool that takes an address is redirect_thread. It sends nothing itself, but it opens a thread to that address, and send_reply on the new thread writes to it. That address usually comes from an inbound email, so the skill shows it to you, with the sentence it came from, and waits for you to confirm before redirecting. set_run_settings with autoSend: true lets future batches go out with no review; the skill only sets it when you ask for it.
