agentity-mcp 0.1.1

Agentity MCP protocol plugin for Anthropic

agentity-mcp

MCP (Model Context Protocol) plugin for Agentity. Wrap any MCP server to inject Agentity identity into tool calls — enabling scoped, verifiable agent-to-tool requests.

Installation

pip install agentity-mcp

Usage

from agentity_mcp import McpServerWrapper

# Wrap an MCP server with Agentity identity
wrapper = McpServerWrapper()

print(f"Agent DID: {wrapper.agent_did}")
print(f"Scopes: {wrapper.agent_scope}")

# Get signed headers for any MCP request
headers = wrapper.get_headers(method="POST", path="/tools/call", body=b'{}')
# {
#   "Agentity-Token": "<base64(AID)>.<base64(sig)>",
#   "Agentity-Nonce": "<uuid-v4>",
#   "Agentity-Timestamp": "<ISO-8601>",
# }

Custom keypair and identity

from agentity_sdk import AgentKeyPair
from agentity_mcp import McpServerWrapper

kp = AgentKeyPair()
aid = kp.create_identity(
    owner_did="did:agentity:human:alice",
    scopes=["mcp:tool:call", "mcp:resource:read"],
    ttl_days=30,
)

wrapper = McpServerWrapper(keypair=kp, identity=aid)

Default scopes

When no identity is provided, McpServerWrapper auto-creates one with scopes:

• mcp:tool:call
• mcp:resource:read
