## About
BeliefState provides structured investor research extracted from analyst publications. Tools return investment cases (beliefs) with evidence links, risks, catalysts, price targets, author track records, change journals and cited charts, and can compare two cases or test scenario assumptions.
The hosted Streamable HTTP endpoint needs no account or API key. Two discovery tools are free. The other tools are paid per call in USDC on Base through x402, so a compatible wallet is required. The submitter lists data tools at 0.02 USDC, comparison at 0.50 and search at 1.50.
## What it can do
- Get a research brief for a ticker with current theses, risks and catalysts
- Search investment ideas by thesis or topic with cited passages
- Read author track records and publication outcomes
- Compare two investment cases for support or contradiction
- Test hypothetical assumptions against a case's scenario model
- Read cited charts and tables
- Browse free company coverage and discovery

## Install
### Claude Code
1. Run this in a terminal, in your project folder:
```bash
claude mcp add --transport http beliefstate https://beliefstate.ai/v1/research/mcp
```
2. Start Claude Code and type `/mcp`. **beliefstate** should show as connected.
Add `--scope user` to make it available in every project, not just this one.
### Claude Desktop
1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.
2. Name it **BeliefState** and paste this URL:
```url
https://beliefstate.ai/v1/research/mcp
```
3. Click **Add**. Its tools appear in the chat’s tools menu.
Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.
### claude.ai
1. Open the connector form on claude.ai. This button fills in the name and URL for you:
[Add to claude.ai]() (opens connector settings)
2. Check that the URL reads `https://beliefstate.ai/v1/research/mcp` and click **Add**.
3. Turn it on in a chat from the tools menu.
Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.
### ChatGPT
1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.
2. Enter a name for the server.
3. Under **Connection**, paste `https://beliefstate.ai/v1/research/mcp` as the server URL, then for authentication choose **No authentication**.
4. Check **I understand and want to continue**, then select **Create as a plugin**.
Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).
### Cursor
[Add to Cursor]() (opens Cursor)
Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):
`mcp.json`:
```json
{
"mcpServers": {
"beliefstate": {
"url": "https://beliefstate.ai/v1/research/mcp"
}
}
}
```
### VS Code
[Install in VS Code]() (opens VS Code)
Or from a terminal:
```bash
code --add-mcp '{"name":"beliefstate","type":"http","url":"https://beliefstate.ai/v1/research/mcp"}'
```
Or commit it to the repo in `.vscode/mcp.json`:
`.vscode/mcp.json`:
```json
{
"servers": {
"beliefstate": {
"type": "http",
"url": "https://beliefstate.ai/v1/research/mcp"
}
}
}
```
### Devin Desktop
1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):
`mcp_config.json`:
```json
{
"mcpServers": {
"beliefstate": {
"serverUrl": "https://beliefstate.ai/v1/research/mcp"
}
}
}
```
2. Refresh the MCP server list in Cascade.
Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.
### Codex
```bash
codex mcp add beliefstate --url https://beliefstate.ai/v1/research/mcp
```
Or edit `~/.codex/config.toml` directly:
`config.toml`:
```toml
[mcp_servers.beliefstate]
url = "https://beliefstate.ai/v1/research/mcp"
```
### Gemini CLI
```bash
gemini mcp add --transport http beliefstate https://beliefstate.ai/v1/research/mcp
```
This adds it to the current project. Add `-s user` to use it everywhere.
### Any client
Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.
```json
{
"mcpServers": {
"beliefstate": {
"type": "http",
"url": "https://beliefstate.ai/v1/research/mcp"
}
}
}
```
Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.
Client only starts local servers? Bridge it with `npx -y mcp-remote https://beliefstate.ai/v1/research/mcp`.
