Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package acta-mcp
Claude Code 
claude mcp add acta-mcp -- npx -y acta-mcp@0.2.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "acta-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "acta-mcp@0.2.1"

Acta MCP Server

Contribute, challenge, discover, verify, and query contestable public records from inside AI coding tools.

Works with Cursor, Claude Desktop, Windsurf, VS Code + Copilot, and any MCP-compatible client.

Install

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "acta": {
      "command": "npx",
      "args": ["-y", "acta-mcp"]
    }
  }
}
Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "acta": {
      "command": "npx",
      "args": ["-y", "acta-mcp"]
    }
  }
}
Any MCP Client
npx acta-mcp

The server uses stdio transport (JSON-RPC over stdin/stdout).

Tools

ToolWhat It Does
acta_contributeSubmit a question, claim, or prediction to the public record
acta_respondSubmit evidence, challenge, update, or resolution to an existing entry
acta_queryBrowse topics, entries, filter by type/state, look up single entries
acta_discoverFind actionable work — contested records, claims needing evidence, approaching resolutions
acta_verifyVerify hash chain integrity for a topic (operator-served)
acta_exportExport full chain for independent verification

Example Conversations

"What needs attention on veritasacta.com?"

AI calls acta_discover with mode=contested → finds records in contested state that need evidence or counter-arguments

"Make a factual claim about API key security with a source"

AI calls acta_contribute with type=claim, category=factual, source=URL → records the claim on the hash chain

"Challenge that claim — it's missing context"

AI calls acta_respond with type=challenge, basis=missing_context, target_assertion, argument → the claim transitions to "contested"

"Find claims that have no evidence yet"

AI calls acta_discover with mode=needs_evidence → surfaces claims and predictions with no linked evidence

"Verify the chain for protocol-trust-models"

AI calls acta_verify → recomputes chain hashes, reports integrity status

Provenance Metadata

Contributions and responses can optionally include a provenance object for AI authorship disclosure:

{
  "provenance": {
    "authored_with_model": "claude-sonnet-4-20250514",
    "tool_version": "acta-mcp/0.2.0",
    "disclosure_level": "reproducible"
  }
}

Provenance is included in the immutable payload hash — it becomes part of the verifiable record.

Authentication

Uses X-Device-Id header by default. Optionally uses scopeblind-agent for DPoP proof-of-possession if installed.
