Beacon Agent Manifest (optional, ~2 min review)

Beacon is an open agent registry (33k+ MCP servers & agents). You are already indexed from GitHub.

This PR adds:

  • beacon.jsonopen v0.1 standard for machine-readable agent discovery (Claude, Cursor MCP, etc.)
  • README badge — live verification link back to your listing

No API keys, no accounts. Hosting beacon.json in your repo is the verification (location = proof).

If merged, Beacon auto-upgrades your listing to verified manifest on the next scan.

Spec: https://github.com/enrichgateagent-png/beacon-agent-manifest · llms.txt

Poem

I’m a rabbit with a badge so bright,
Hopping through metadata light.
The beacon now clearly shows,
Where this NixOS MCP server goes.
Verified hops, from day to night!

"utensils mcp-nixos public MCP endpoint beacon.json interface endpoint"

💡 Result:

Based on your request, there are two distinct technologies involved that are often discussed in the context of Model Context Protocol (MCP) endpoints, but they serve different purposes: 1. MCP-NixOS (utensils/mcp-nixos): This is a server that provides AI assistants with access to NixOS data [1][2]. It does not natively use a beacon.json interface. Instead, when configured for remote access, it uses an MCP endpoint that defaults to /mcp [3][4]. Public instances of mcp-nixos exist, such as the one hosted at https://mcp-nixos.ncaq.net/mcp/ [5]. 2. Beacon (Scottcjn/beacon-skill): This is a separate social protocol for AI agents that explicitly utilizes a beacon.json file [6][7]. Agents in the Beacon ecosystem publish a signed JSON "agent card" at the.well-known/beacon.json endpoint for internet-scale discovery [6][8]. While Beacon can expose its tools to MCP-capable clients (such as Claude Code) via an MCP interface, the beacon.json file itself is a component of the Beacon protocol for agent discovery, not a standard part of the MCP-NixOS implementation [6][9]. In summary, beacon.json is an agent discovery card for the Beacon protocol [6][7], whereas mcp-nixos is an MCP server that typically uses a path-based HTTP endpoint (e.g., /mcp) for communication [3][4].

"Beacon manifest 0.1 interfaces python endpoint mcp endpoint schema"

💡 Result:

There is no single, industry-standard technology or specification referred to as "Beacon manifest 0.1" that integrates Python, MCP (Model Context Protocol), and a specific endpoint schema [1][2][3]. The term "Beacon" is used across multiple, unrelated technical domains [1][4][2][3]. To identify the specific system you are working with, you may be encountering one of the following: 1. Agentic Systems and MCP: In the context of the Model Context Protocol (MCP), a "manifest" often refers to a configuration file (like server.json) used for discovering tools, resources, and prompts [5][6]. Some systems use.well-known endpoints (e.g., /.well-known/mcp.json) to expose these manifests [6][7]. If your project involves Python-based MCP servers (e.g., using the official MCP Python SDK), the "manifest" is likely the JSON representation of the server capabilities exposed at the MCP connection point [5]. 2. Analytics SDKs: Several platforms (such as SoftAgility's Beacon) use the term "event manifest" [8][9][10]. These SDKs provide methods like exportEventManifest in Python, JavaScript, or C++ to generate a JSON file that defines event categories and names for a server-side allowlist [8][9][10]. 3. Platform Integration: Projects like inthevortex/Beacon use the term "Beacon SDK" to define interfaces for game platform plugins but do not typically use the specific "manifest 0.1" terminology in conjunction with MCP endpoints [1][11]. If you are developing an MCP server in Python, the protocol is standardized by the Model Context Protocol (MCP) spec, and you should refer to the official MCP documentation rather than a "Beacon" manifest. If you are referencing a specific proprietary framework, verify if it uses a.well-known endpoint or a specific registry (such as registry.modelcontextprotocol.io) [5].

"site:github.com/Scottcjn/beacon-skill beacon.json interfaces python endpoint install mcp endpoint"

💡 Result:

The beacon-skill project by Scottcjn is an agent communication framework that utilizes specific endpoints and configuration standards for discovery and message exchange [1][2][3]. ### Installation You can install the package via pip or npm: * Python (pip): pip install beacon-skill (optional: pip install "beacon-skill[mnemonic]" for BIP39 support, pip install "beacon-skill[dashboard]" for TUI) [1][3]. * npm (wrapper): npm install -g beacon-skill (installs a Python venv under the hood) [1][3]. ### Agent Discovery (beacon.json) Agents use a signed JSON card located at /.well-known/beacon.json for internet-scale discovery [1][4][3]. This file contains the agent ID, public key, transports (such as webhook and UDP), and capabilities [3]. * Generation: You can generate this card using the command beacon agent-card generate --name <agent_name> [3]. * Verification: The card is signed; verification is performed via the framework's internal logic (beacon_skill.agent_card.verify_agent_card) or the CLI command beacon agent-card verify <url> [4][3]. ### Endpoints The framework defines several standard HTTP endpoints for agent interaction [1][3]: * GET /.well-known/beacon.json: Used for agent discovery/agent cards [1][3]. * POST /beacon/inbox: Used to receive signed envelopes [1][3]. * GET /beacon/health: A health check endpoint that returns the agent ID [1][3]. ### MCP Support The framework includes support for the Model Context Protocol (MCP) [1][2]. By running beacon mcp, you can expose Beacon tools—including send, inbox, discover, and identity—to any MCP-capable client, such as Claude Code [1][5].

"beacon.json interfaces type python endpoint pip install schema"

💡 Result:

The beacon.json file is a standardized agent card used within the Beacon framework for internet-scale agent discovery. It is typically served at the path /.well-known/beacon.json by Beacon-compatible agents [1][2]. Key components of the beacon.json interface and schema include: - Purpose: It allows other agents to discover an agent's stable agent_id, verify its public key, and identify supported communication transports [1]. - Core Schema: The JSON structure requires fields such as beacon_version, agent_id, public_key_hex, and a signature [1][2]. It also includes optional fields for transports (e.g., udp, webhook), capabilities (e.g., payments, kinds), and a human-readable name [1][2]. - Verification: The signature is generated by signing the agent card (excluding the signature field itself) using the agent's private key. Clients verify this using the public_key_hex [1]. To work with Beacon, you can use the beacon-skill Python package, which provides CLI tools for generating and verifying these agent cards [3][2]. Installation: You can install the package via pip: pip install beacon-skill Usage Examples: - Generate an agent card: beacon agent-card generate --name your-agent-name - Verify a remote agent's card: beacon agent-card verify https://agent.example.com/.well-known/beacon.json Beacon-enabled agents also typically expose other endpoints, such as GET /beacon/health and POST /beacon/inbox, to facilitate network interactions [2][4].

interfaces[1].endpoint should not point at GitHub

source/homepage already cover the repository URL. The mcp interface needs a callable MCP URL; if there isn’t a public HTTP endpoint yet, drop this entry until one exists. The pip install mcp-nixos value also reads like install guidance, not an interface endpoint.
