Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02689 | $0.02689 |
| Opus 5 | $0.01345 | $0.01345 |
| Sonnet 5 | $0.00538 | $0.00538 |
| Haiku 4.5 | $0.00269 | $0.00269 |
Grade A, and why
mockd CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What is mockd?
mockd is a multi-protocol API mock server. It mocks HTTP, GraphQL, gRPC, WebSocket, MQTT, SSE, and SOAP from a single binary. It has a built-in MCP server with 18 tools — you can create, manage, and debug mocks directly via MCP without CLI commands.
MCP Server
mockd has an MCP server. If it's configured in your MCP settings, use the MCP tools directly:
manage_mock— Create, list, get, update, delete, or toggle mocks (action parameter)manage_context— View or switch admin server context (action: get/switch; name for switch)manage_workspace— List, switch, or create workspaces (action: list/switch/create; id, name)import_mocks— Import from OpenAPI, Postman, HAR, WireMock, cURL, WSDL, Mockoon, or YAMLexport_mocks— Export all mocks as YAML/JSONget_server_status— Health check, ports, and statistics (no params)get_request_logs— See all captured traffic (limit, offset, method, pathPrefix, mockId, protocol, unmatchedOnly)clear_request_logs— Remove all captured request/response logs (no params)get_chaos_config— Current chaos fault injection config and statistics (no params)set_chaos_config— Inject latency, errors, apply chaos profiles, or configure advanced rules (circuit breaker, retry-after, progressive degradation)reset_chaos_stats— Reset chaos counters to zero without changing config (no params)get_stateful_faults— View circuit breaker, retry-after, and progressive degradation statemanage_circuit_breaker— Trip or reset circuit breakers manually (action: trip/reset; key)verify_mock— Assert a mock was called N times (id, expected_count, at_least, at_most)get_mock_invocations— See what requests hit a mock (id, limit)reset_verification— Clear invocation records and counters for one mock or all (id optional, omit for all)manage_state— CRUD stateful resources (action: overview/add_resource/list_items/get_item/create_item/reset/delete_resource; resource, item_id, data, seed_data, etc.)manage_custom_operation— Manage custom operations on stateful resources (action: list/get/register/delete/execute; name, definition, input)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mockd CLAUDE.md is an instructions file published in the GitHub repository getmockd/mockd (144 stars, last pushed 15d ago), licensed Apache-2.0. It adds 2,689 tokens to every session, about $0.0134 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
