发布到官方 MCP 注册表时如何认证

MCP 注册表目前处于预览阶段。在正式发布之前可能发生破坏性变更或数据重置。如果你遇到任何问题，请在 GitHub 上报告。

在发布到官方 MCP 注册表之前，你必须先认证。MCP 注册表支持不同的认证方法。你选择哪种认证方法，决定了你服务器名称的命名空间。如果你选择基于 GitHub 的认证，你在 server.json 中的服务器名称**必须（MUST）**为 io.github.username/*（或 io.github.orgname/*）的形式。例如 io.github.alice/weather-server。如果你选择基于域名的认证，你在 server.json 中的服务器名称**必须（MUST）**为 com.example.*/* 的形式，其中 com.example 是你域名的反向 DNS 形式。例如 io.modelcontextprotocol/everything。

认证方式	名称格式	示例名称
基于 GitHub	`io.github.username/` 或 `io.github.orgname/`	`io.github.alice/weather-server`
基于域名	`com.example./`	`io.modelcontextprotocol/everything`

GitHub 认证

GitHub 认证使用由 mcp-publisher CLI 工具发起的 OAuth 流。要执行 GitHub 认证，导航到你的服务器项目目录并运行：

mcp-publisher login github

你应当看到类似下面的输出：

Output

Logging in with github...

To authenticate, please:
1. Go to: https://github.com/login/device
2. Enter code: ABCD-1234
3. Authorize this application
Waiting for authorization...

访问该链接，按提示操作，并输入终端中打印的授权码（例如上面输出中的 ABCD-1234）。完成后，回到终端，你应当看到类似下面的输出：

Output

Successfully authenticated!
✓ Successfully logged in

DNS 认证

DNS 认证是一种基于域名的认证方法，依赖于一条 DNS TXT 记录。要使用 mcp-publisher CLI 工具执行 DNS 认证，在你的服务器项目目录中运行以下命令，基于一对公钥/私钥生成一条 TXT 记录：

MY_DOMAIN="example.com"

# Generate public/private key pair using Ed25519
openssl genpkey -algorithm Ed25519 -out key.pem

# Generate TXT record
PUBLIC_KEY="$(openssl pkey -in key.pem -pubout -outform DER | tail -c 32 | base64)"
echo "${MY_DOMAIN}. IN TXT \"v=MCPv1; k=ed25519; p=${PUBLIC_KEY}\""

MY_DOMAIN="example.com"

# Generate public/private key pair using ECDSA P-384
openssl genpkey -algorithm EC -pkeyopt ec_paramgen_curve:secp384r1 -out key.pem

# Generate TXT record
PUBLIC_KEY="$(openssl ec -in key.pem -text -noout -conv_form compressed | grep -A4 "pub:" | tail -n +2 | tr -d ' :\n' | xxd -r -p | base64)"
echo "${MY_DOMAIN}. IN TXT \"v=MCPv1; k=ecdsap384; p=${PUBLIC_KEY}\""

MY_DOMAIN="example.com"
MY_PROJECT="myproject"
MY_KEYRING="mykeyring"
MY_KEY_NAME="mykey"

# Log in using gcloud CLI (https://cloud.google.com/sdk/docs/install)
gcloud auth login

# Set default project
gcloud config set project "${MY_PROJECT}"

# Create a keyring in your project
gcloud kms keyrings create "${MY_KEYRING}" --location global

# Create an Ed25519 signing key
gcloud kms keys create "${MY_KEY_NAME}" --default-algorithm=ec-sign-ed25519 --purpose=asymmetric-signing --keyring="${MY_KEYRING}" --location=global

# Enable Application Default Credentials (ADC) so the publisher tool can sign
gcloud auth application-default login

# Attempt login to show the public key
mcp-publisher login dns google-kms --domain="${MY_DOMAIN}" --resource="projects/${MY_PROJECT}/locations/global/keyRings/${MY_KEYRING}/cryptoKeys/${MY_KEY_NAME}/cryptoKeyVersions/1"

# Copy the "Expected proof record":
# ${MY_DOMAIN}. IN TXT "v=MCPv1; k=ed25519; p=${PUBLIC_KEY}"

MY_DOMAIN="example.com"
MY_SUBSCRIPTION="subscription name or ID"
MY_RESOURCE_GROUP="MyResourceGroup"
MY_KEY_VAULT="MyKeyVault"
MY_KEY_NAME="MyKey"

# Log in using Azure CLI (https://learn.microsoft.com/en-us/cli/azure/install-azure-cli)
az login

# Set default subscription
az account set --subscription "${MY_SUBSCRIPTION}"

# Create a resource group
az group create --location westus --resource-group "${MY_RESOURCE_GROUP}"

# Create a key vault
az keyvault create --name "${MY_KEY_VAULT}" --location westus --resource-group "${MY_RESOURCE_GROUP}"

# Create an ECDSA P-384 signing key
az keyvault key create --name "${MY_KEY_NAME}" --vault-name "${MY_KEY_VAULT}" --curve P-384

# Attempt login to show the public key
mcp-publisher login dns azure-key-vault --domain="${MY_DOMAIN}" --vault "${MY_KEY_VAULT}" --key "${MY_KEY_NAME}"

# Copy the "Expected proof record":
# ${MY_DOMAIN}. IN TXT "v=MCPv1; k=ecdsap384; p=${PUBLIC_KEY}"

然后使用你的 DNS 提供方的控制面板添加该 TXT 记录。TXT 记录可能需要几分钟才能传播。TXT 记录传播完成后，使用 mcp-publisher login 命令登录：

MY_DOMAIN="example.com"

PRIVATE_KEY="$(openssl pkey -in key.pem -noout -text | grep -A3 "priv:" | tail -n +2 | tr -d ' :\n')"
mcp-publisher login dns --domain "${MY_DOMAIN}" --private-key "${PRIVATE_KEY}"

MY_DOMAIN="example.com"

PRIVATE_KEY="$(openssl ec -in key.pem -noout -text | grep -A4 "priv:" | tail -n +2 | tr -d ' :\n')"
mcp-publisher login dns --domain "${MY_DOMAIN}" --private-key "${PRIVATE_KEY}"

MY_DOMAIN="example.com"
MY_PROJECT="myproject"
MY_KEYRING="mykeyring"
MY_KEY_NAME="mykey"

mcp-publisher login dns google-kms --domain="${MY_DOMAIN}" --resource="projects/${MY_PROJECT}/locations/global/keyRings/${MY_KEYRING}/cryptoKeys/${MY_KEY_NAME}/cryptoKeyVersions/1"

MY_DOMAIN="example.com"
MY_KEY_VAULT="MyKeyVault"
MY_KEY_NAME="MyKey"

mcp-publisher login dns azure-key-vault --domain="${MY_DOMAIN}" --vault "${MY_KEY_VAULT}" --key "${MY_KEY_NAME}"

HTTP 认证

HTTP 认证是一种基于域名的认证方法，依赖于托管在你域名上的一个 /.well-known/mcp-registry-auth 文件。例如 https://example.com/.well-known/mcp-registry-auth。要使用 mcp-publisher CLI 工具执行 HTTP 认证，在你的服务器项目目录中运行以下命令，基于一对公钥/私钥生成一个 mcp-registry-auth 文件：

# Generate public/private key pair using Ed25519
openssl genpkey -algorithm Ed25519 -out key.pem

# Generate mcp-registry-auth file
PUBLIC_KEY="$(openssl pkey -in key.pem -pubout -outform DER | tail -c 32 | base64)"
echo "v=MCPv1; k=ed25519; p=${PUBLIC_KEY}" > mcp-registry-auth

# Generate public/private key pair using ECDSA P-384
openssl genpkey -algorithm EC -pkeyopt ec_paramgen_curve:secp384r1 -out key.pem

# Generate mcp-registry-auth file
PUBLIC_KEY="$(openssl ec -in key.pem -text -noout -conv_form compressed | grep -A4 "pub:" | tail -n +2 | tr -d ' :\n' | xxd -r -p | base64)"
echo "v=MCPv1; k=ecdsap384; p=${PUBLIC_KEY}" > mcp-registry-auth

MY_DOMAIN="example.com"
MY_PROJECT="myproject"
MY_KEYRING="mykeyring"
MY_KEY_NAME="mykey"

# Log in using gcloud CLI (https://cloud.google.com/sdk/docs/install)
gcloud auth login

# Set default project
gcloud config set project "${MY_PROJECT}"

# Create a keyring in your project
gcloud kms keyrings create "${MY_KEYRING}" --location global

# Create an Ed25519 signing key
gcloud kms keys create "${MY_KEY_NAME}" --default-algorithm=ec-sign-ed25519 --purpose=asymmetric-signing --keyring="${MY_KEYRING}" --location=global

# Enable Application Default Credentials (ADC) so the publisher tool can sign
gcloud auth application-default login

# Attempt login to show the public key
mcp-publisher login http google-kms --domain="${MY_DOMAIN}" --resource="projects/${MY_PROJECT}/locations/global/keyRings/${MY_KEYRING}/cryptoKeys/${MY_KEY_NAME}/cryptoKeyVersions/1"

# Copy the "Expected proof record" to `./mcp-registry-auth`:
# v=MCPv1; k=ed25519; p=${PUBLIC_KEY}

MY_DOMAIN="example.com"
MY_SUBSCRIPTION="subscription name or ID"
MY_RESOURCE_GROUP="MyResourceGroup"
MY_KEY_VAULT="MyKeyVault"
MY_KEY_NAME="MyKey"

# Log in using Azure CLI (https://learn.microsoft.com/en-us/cli/azure/install-azure-cli)
az login

# Set default subscription
az account set --subscription "${MY_SUBSCRIPTION}"

# Create a resource group
az group create --location westus --resource-group "${MY_RESOURCE_GROUP}"

# Create a key vault
az keyvault create --name "${MY_KEY_VAULT}" --location westus --resource-group "${MY_RESOURCE_GROUP}"

# Create an ECDSA P-384 signing key
az keyvault key create --name "${MY_KEY_NAME}" --vault-name "${MY_KEY_VAULT}" --curve P-384

# Attempt login to show the public key
mcp-publisher login http azure-key-vault --domain="${MY_DOMAIN}" --vault "${MY_KEY_VAULT}" --key "${MY_KEY_NAME}"

# Copy the "Expected proof record" to `./mcp-registry-auth`:
# v=MCPv1; k=ecdsap384; p=${PUBLIC_KEY}

然后将 mcp-registry-auth 文件托管在你域名的 /.well-known/mcp-registry-auth。文件托管完成后，使用 mcp-publisher login 命令登录：

MY_DOMAIN="example.com"
PRIVATE_KEY="$(openssl pkey -in key.pem -noout -text | grep -A3 "priv:" | tail -n +2 | tr -d ' :\n')"
mcp-publisher login http --domain "${MY_DOMAIN}" --private-key "${PRIVATE_KEY}"

MY_DOMAIN="example.com"
PRIVATE_KEY="$(openssl ec -in key.pem -noout -text | grep -A4 "priv:" | tail -n +2 | tr -d ' :\n')"
mcp-publisher login http --domain "${MY_DOMAIN}" --private-key "${PRIVATE_KEY}"

MY_DOMAIN="example.com"
MY_PROJECT="myproject"
MY_KEYRING="mykeyring"
MY_KEY_NAME="mykey"

mcp-publisher login http google-kms --domain="${MY_DOMAIN}" --resource="projects/${MY_PROJECT}/locations/global/keyRings/${MY_KEYRING}/cryptoKeys/${MY_KEY_NAME}/cryptoKeyVersions/1"

MY_DOMAIN="example.com"
MY_KEY_VAULT="MyKeyVault"
MY_KEY_NAME="MyKey"

mcp-publisher login http azure-key-vault --domain="${MY_DOMAIN}" --vault "${MY_KEY_VAULT}" --key "${MY_KEY_NAME}"
