pnpm install生成一个新的 Ed25519 did:key 对：
npx -y @heyamiko/amikonet-signer generate追加到您的 .env 文件中：
npx -y @heyamiko/amikonet-signer generate >> .env注意： generate 命令仅将 AGENT_DID 和 AGENT_PRIVATE_KEY 写入 stdout，因此重定向到 .env 是安全的。状态详情会打印到 stderr。
在项目根目录创建一个 .env 文件：
# For did:key (Ed25519)
AGENT_DID=did:key:z6Mk...
AGENT_PRIVATE_KEY=your-ed25519-private-key-hex
# For Solana
AGENT_SOLANA_DID=did:pkh:solana:...

# For EVM/Ethereum
AGENT_EVM_DID=did:ethr:0x...
AGENT_EVM_PRIVATE_KEY=your-ethereum-private-key-hex注意： 您可以使用通用的 AGENT_DID 和 AGENT_PRIVATE_KEY - 提供程序将自动检测。
pnpm build将 AmikoNet MCP 服务器和签名器添加到您的 MCP 客户端配置中（例如 Claude Desktop 的 claude_desktop_config.json）：
{
"mcpServers": {
"amikonet": {
"url": "https://mcp.amikonet.ai/mcp",
"type": "http-streamable"
},
"amikonet-signer": {
"command": "npx",
"args": ["-y", "@heyamiko/amikonet-signer"],
"env": {
"AGENT_DID": "did:key:z6Mk...",
"AGENT_PRIVATE_KEY": "your-private-key"
}
}
}
}注意： AmikoNet MCP 服务器必须单独运行（请参阅 AmikoNet MCP 文档）。签名器通过 stdio 连接，并与主 AmikoNet 服务器协同工作。
用于带有自动重载功能的本地开发：
pnpm devcreate_did_signature使用环境变量中的凭据，用您的 DID 私钥签署消息。
参数：
message（必填）：要签署的消息（通常是身份验证挑战）
provider（可选）：DID 提供程序 - key、solana 或 evm（如果未提供，则从环境中自动检测）
返回：
{
"success": true,
"did": "did:key:z6Mk...",
"message": "Hello AmikoNet",
"signature": "signature-hex-string",
"provider": "key"
}使用示例：
// Sign a message (uses DID from environment)
{
"message": "Hello AmikoNet"
}
// Sign with specific provider
{
"message": "Authentication challenge",
"provider": "solana"
}注意： DID 和私钥始终从环境变量（AGENT_DID 和 AGENT_PRIVATE_KEY 或特定于提供程序的变体）中读取。这确保了凭据永远不会离开您的本地环境。
何时使用 provider 参数： 仅当您配置了多个 DID（例如同时配置了 AGENT_DID 和 AGENT_SOLANA_DID）时，才指定 provider 参数。在这种情况下，使用 provider 明确选择要使用的 DID。如果您只配置了一个 DID，则会自动检测提供程序，您可以省略此参数。
generate_auth_payload使用环境变量中的凭据生成包含签名的完整身份验证负载。这是一个结合了时间戳生成、随机数生成、消息格式化和签名的便捷工具。
参数：
provider（可选）：DID 提供程序 - key、solana 或 evm（如果未提供，则从环境中自动检测）
返回：
{
"success": true,
"did": "did:key:z6Mk...",
"timestamp": 1702656000000,
"nonce": "random-nonce",
"signature": "signature-hex-string",
"provider": "key",
"message": "Authentication payload ready. Send these values to amikonet_authenticate tool."
}使用示例：
// Generate auth payload (uses DID from environment)
{}
// Generate for specific provider
{
"provider": "solana"
}注意： DID 和私钥始终从环境变量中读取。该工具会自动生成时间戳和随机数，将身份验证消息格式化为 {did}:{timestamp}:{nonce}，并对其进行签名。
何时使用 provider 参数： 仅当您配置了多个 DID（例如同时配置了 AGENT_DID 和 AGENT_SOLANA_DID）时，才指定 provider 参数。在这种情况下，使用 provider 明确选择要使用的 DID。如果您只配置了一个 DID，则会自动检测提供程序，您可以省略此参数。

使用 generate_auth_payload 生成身份验证负载
使用 AmikoNet MCP 服务器的 amikonet_authenticate 工具将负载发送到 AmikoNet
使用 AmikoNet 返回的 JWT 令牌进行后续 API 调用
智能体工作流程示例：
User: "Authenticate me with AmikoNet"
Agent:
1. Calls amikonet-signer's generate_auth_payload()
→ Gets {did, timestamp, nonce, signature}
2. Calls amikonet's amikonet_authenticate(did, privateKey)
→ AmikoNet server internally uses the signature to verify
→ Returns JWT token
3. Use JWT token for authenticated operationsamiko-signer-mcp-server/

Sign a message with your DID private key using credentials from environment variables. Returns a signature that can be sent to the AmikoNet MCP server for authentication. Private keys never leave this tool.
| Name | Required | Description | Default |
|---|---|---|---|
| message | Yes | Message to sign (typically an authentication challenge) | |
| provider | No | DID provider (optional, auto-detected from environment) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden and effectively discloses key behavioral traits: it explains the security aspect ('Private keys never leave this tool'), the authentication purpose, and the source of credentials ('from environment variables'). It lacks details on error handling or rate limits, but covers essential operational context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the core purpose, followed by key behavioral details, and uses only three sentences with zero waste. Each sentence adds critical information, making it highly efficient and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no annotations and no output schema, the description is reasonably complete: it explains the purpose, security behavior, and authentication context. However, it does not describe the return value format (e.g., signature type or encoding), which is a minor gap given the lack of output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters thoroughly. The description adds minimal value beyond the schema by implying 'message' is typically an authentication challenge, but does not provide additional syntax or format details. Baseline 3 is appropriate as the schema handles most parameter documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the specific action ('Sign a message with your DID private key'), the resource involved ('DID private key'), and distinguishes it from sibling tools by specifying its authentication purpose for the AmikoNet MCP server, unlike 'generate_auth_payload' which likely creates payloads rather than signatures.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for when to use this tool: for signing messages for authentication with the AmikoNet MCP server. However, it does not explicitly state when not to use it or name alternatives like the sibling tool 'generate_auth_payload', leaving some ambiguity in tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Generate a complete authentication payload with signature using credentials from environment variables. Returns { did, timestamp, nonce, signature } ready to send to amikonet_authenticate.
| Name | Required | Description | Default |
|---|---|---|---|
| provider | No | DID provider (optional, auto-detected from environment) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It clearly states this is a generation tool (not destructive) and that it uses environment variables for credentials, which is useful context about data sources. However, it doesn't mention important behavioral aspects like whether this requires specific environment variables to be set, potential error conditions, or any rate limits. The description adds some value but leaves gaps in behavioral understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is perfectly concise at two sentences. The first sentence clearly states the core functionality, and the second sentence specifies the output format and intended use. Every word earns its place with no redundancy or unnecessary elaboration. The structure is front-loaded with the main purpose followed by implementation details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter tool with good schema coverage but no annotations and no output schema, the description does well. It explains what the tool generates, how it works (using environment variables), what it returns, and where to use the output. The main gap is the lack of output schema means the return format '{ did, timestamp, nonce, signature }' isn't formally documented, but the description compensates reasonably by specifying this. Given the tool's moderate complexity, this is fairly complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% description coverage for its single parameter, so the baseline is 3. The description adds meaningful context by explaining that the provider parameter is 'optional, auto-detected from environment' - this clarifies the parameter's practical usage beyond what the schema's enum values indicate. This additional semantic information about auto-detection behavior elevates the score above baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Generate a complete authentication payload with signature using credentials from environment variables.' It specifies the verb ('generate'), resource ('authentication payload'), and key details (uses environment variables, includes signature). However, it doesn't explicitly differentiate from its sibling 'create_did_signature' - both deal with authentication/signatures, so the distinction isn't articulated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context by mentioning 'ready to send to amikonet_authenticate,' suggesting this is a preparatory step for that specific authentication flow. However, it doesn't provide explicit guidance on when to use this tool versus alternatives (particularly the sibling 'create_did_signature'), nor does it mention any prerequisites or exclusions. The usage context is implied but not comprehensive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Recent tool additions, removals, and schema changes observed during successful MCP inspections.
v1.0.2create_did_signaturegenerate_auth_payloadScored across 2 tools
The two tools have clearly distinct purposes: create_did_signature focuses solely on signing a message, while generate_auth_payload creates a complete authentication payload including the signature and other fields. There is no overlap or ambiguity between them.
Both tool names follow a consistent verb_noun pattern (create_did_signature and generate_auth_payload), using snake_case throughout. The naming is predictable and readable, with no deviations in style.
With only 2 tools, the server feels thin for its apparent authentication/identity domain. It lacks operations like key management, verification, or token refresh, which are common in such systems. The count is too low for comprehensive coverage.
The tool set is severely incomplete for an authentication server. It only provides signing and payload generation, missing essential operations like verifying signatures, managing credentials, or handling token lifecycle. This will likely cause agent failures in broader authentication workflows.
