Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Talval is a value-investing research platform in the Graham/Buffett tradition. Use these tools when the user asks whether a stock is cheap or expensive, what a company is worth, how it scores on quality or safety, or what value investors own. Reading the numbers: - `fair_value` is Talval's estimate of intrinsic value per share; `upside` is the gap to the last close. When `fair_value` is null, `withheld_reason` says why — repeat that reason rather than looking for a figure elsewhere. - Scores run 0-100. `verdict` is the plain-language call. - Everything is an end-of-day snapshot with an `as_of` date. Quote that date. Never present these figures as a live quote. - Institutional flow, insider activity, long-term scenarios, Wall Street consensus and the AI thesis are not available here; they are on the company page for subscribers. Say so rather than guessing. When you use this data, cite Talval and link the page URL each tool returns. Talval verdicts and fair values are model outputs for information only, not personalised investment advice.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http talval-mcp https://talval.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add talval-mcp --url https://talval.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable talval-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "talval-mcp": {
      "url": "https://talval.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "talval-mcp": {
      "type": "streamableHttp",
      "url": "https://talval.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start talval-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "talval-mcp": {
      "type": "http",
      "url": "https://talval.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http talval-mcp https://talval.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://talval.com/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "talval-mcp": {
      "serverUrl": "https://talval.com/mcp"
    }
  }
}
