Functions

func NewAuthTransport added in v0.3.2 

func NewAuthTransport(spec AuthConfig) (*mcp.StreamableClientTransport, error)

Configures MCP transport with Bearer token authentication.

Types

type AuthConfig added in v0.3.2 

type AuthConfig struct {
	// Endpoint URL of MCP server
	Endpoint string

	// Resource Config file (default is ~/.iqrc) to read credentials from.
	RC string

	// Custom HTTP client (if nil, default client will be used)
	Client *http.Client
}

type Native added in v0.5.0 

type Native interface {
	Bind(*mcp.Server)
	Spec() *mcp.Tool
}

func From added in v0.5.0 

func From[A, B any](spec *mcp.Tool, f mcp.ToolHandlerFor[A, B]) Native

type Registry 

type Registry struct {
	// contains filtered or unexported fields
}

func NewRegistry 

func NewRegistry() *Registry

NewRegistry creates a new registry of MCP servers.

func (*Registry) Attach added in v0.3.0 

func (r *Registry) Attach(id string, server Server) error

Attach MCP server to the registry, making its tools available to the agent. The server is identified by a unique prefix, which is used to namespace tool names (e.g., fs_read). Tool names use underscore separator (prefix_toolname) due to AWS Bedrock constraints which only allow [a-zA-Z0-9_-] characters. The first token before underscore is always the server prefix. Each server runs independently, and its tools are registered with the prefix to avoid naming conflicts.

func (*Registry) ConnectCmd added in v0.3.2 

func (r *Registry) ConnectCmd(id string, cmd []string) error

func (*Registry) ConnectUrl added in v0.3.2 

func (r *Registry) ConnectUrl(id string, url string) error

func (*Registry) Context added in v0.0.20 

func (r *Registry) Context() chatter.Registry

Context returns the registry as LLM embeddable schema. It fetches the list of available tools from all attached MCP servers.

func (*Registry) Invoke added in v0.0.20 

func (r *Registry) Invoke(reply *chatter.Reply) (thinker.Phase, chatter.Message, error)

Invoke executes the tools requested by the LLM via the appropriate MCP server.

func (*Registry) WithNative added in v0.5.0 

func (r *Registry) WithNative(id string, fs ...Native) *Registry

Connect native function as a tool to the registry with the given id.

type SeqRegistry added in v0.5.0 

type SeqRegistry struct {
	// contains filtered or unexported fields
}

func NewSeqRegistry added in v0.5.0 

func NewSeqRegistry() *SeqRegistry

func (*SeqRegistry) Bind added in v0.5.0 

func (r *SeqRegistry) Bind(reg *Registry)

func (*SeqRegistry) Context added in v0.5.0 

func (r *SeqRegistry) Context() chatter.Registry

func (*SeqRegistry) Invoke added in v0.5.0 

func (r *SeqRegistry) Invoke(reply *chatter.Reply) (phase thinker.Phase, msg chatter.Message, err error)

type Server added in v0.3.0 

type Server interface {
	ListTools(ctx context.Context, params *mcp.ListToolsParams) (*mcp.ListToolsResult, error)
	CallTool(ctx context.Context, params *mcp.CallToolParams) (*mcp.CallToolResult, error)
	Close() error
}
