Talarion Acumen MCP
Connect OpenClaw, Hermes, Claude, Cursor, and other AI agents to Talarion’s knowledge base — recent, verified, sourced facts about the world that would be surprising to an LLM.
Installation
Sign into Claude, then add the connector:
Add to ClaudeOr open Claude, go to Connectors, search for Talarion, and click Add.
Tip: toggle Always Allow so Claude.ai doesn’t prompt on every call — you’ll get more use out of the tool. With only one tool exposed, it’s also context-efficient to set Tool access mode → Tools already loaded in Claude.ai’s connector settings.
Sign into ChatGPT, then add the app:
Add to ChatGPTOr open ChatGPT, click Apps, search for Talarion, and hit Connect.
-
Go to dashboard.talarion.com → API Keys → Create key and copy the key.
-
Add Talarion as an MCP server, replacing
YOUR_KEYwith the key you created:
openclaw mcp set talarion \
'{"url":"https://mcp.talarion.com/mcp","transport":"streamable-http","headers":{"Authorization":"Bearer YOUR_KEY"}}'That’s it — Talarion will be available in your next OpenClaw session.
Add Talarion and authorize in the browser:
hermes mcp add talarion --url https://mcp.talarion.com/mcp --auth oauthRun hermes mcp login talarion if you ever need to re-authorize.
On a headless machine, use a workspace API key instead. Create one at
dashboard.talarion.com → API Keys, put it in
~/.hermes/.env as TALARION_API_KEY, then add Talarion to ~/.hermes/config.yaml:
mcp_servers:
talarion:
url: "https://mcp.talarion.com/mcp"
headers:
Authorization: "Bearer ${env:TALARION_API_KEY}"$ claude mcp add --scope user --transport http talarion https://mcp.talarion.com/mcpRun once. Then, open Claude Code, type /mcp, and click Authorize next to Talarion.
Add Talarion to ~/.gemini/settings.json:
{
"mcpServers": {
"talarion": {
"httpUrl": "https://mcp.talarion.com/mcp"
}
}
}Or add manually to ~/.cursor/mcp.json:
{
"mcpServers": {
"talarion": {
"url": "https://mcp.talarion.com/mcp"
}
}
}
