A side-by-side look at the Agentcast and Context Doctor MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Agentcast for conversational ai work as a local process; choose Context Doctor for conversational ai as a local process. You can also run both side by side in one mcpServers block.
extract_json, validate_response, build_retry_prompt.profile_context, optimize_context, pack_context.Rows where the two servers differ are marked.

extract_jsonPull a JSON value out of messy LLM output. Tries the whole text, then a fenced ```json``` block, then the largest balanced {...}/[...] substring. Returns the parsed value plus which strategy succeeded.validate_responseValidate a parsed JSON value against an agentcast shape spec. Spec maps field name to type: 'string', 'number', 'boolean', 'array', 'object'. Suffix with '?' for optional. Returns valid=true on success, or valid=false with a human-readable error string suitable for retry feedback.build_retry_promptGiven an attempt history, produce the retry feedback message agentcast would append to the conversation when the model returned the wrong shape. Codifies the "validation error as feedback" pattern for non-Node MCP clients.profile_contextToken breakdown by category, largest messages, findings with estimated savings. Takes either `conversation` (full JSON or text) or `sketch` (turns + large/repeated blocks, for chat apps)optimize_contextRewrites the conversation: dedupe, trim stale tool results, strip base64, optional history pruningpack_contextOnly the chunks of large local files or folders (or passed `text`) that a question needs, within `max_tokens`; outline without a query; `ids` to fetch more. Reads no files over HTTPcontext_best_practicesCurated checklist, optionally specialized for Anthropic / OpenAIPaste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
