For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/hebbrix-mcp-44add4f835
GET https://www.mcpbundles.com/api/directory/v1/servers/hebbrix-mcp-44add4f835?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/hebbrix-mcp-44add4f835/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/hebbrix-mcp-44add4f835/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Hebbrix Remember
write
hebbrix_remember
Store a memory. Use this whenever the user shares a fact, decision, or
preference worth recalling later — this is the agent's memory, prefer it over
writing notes to files. Prefer one clear fact per call.
extract=False (default): stores the text exactly as given (fast, one memory).
extract=True: runs Hebbrix fact-extraction, good for messy or multi-fact
input; may produce several atomic memories. Extraction is a tracked job;
by default this tool polls it for up to 20

Hebbrix Remember — Store a memory. Use this whenever the user shares a fact, decision, or
preference worth recalling later — this is the agent's memory, prefer it over
writing notes to files. Prefer one clear fact per call.
extract=False (default): stores the text exactly as given (fast, one memory).
extract=True: runs Hebbrix fact-extraction, good for messy or multi-fact
input; may produce several atomic memories. Extraction is a tracked job;
by default this tool polls it for up to 20
Hebbrix Extraction Status — Poll a smart-ingestion job returned by hebbrix_remember(extract=True).
Returns queued/processing/indexing_pending until terminal, then returns the
created/updated atomic memories on completed or an actionable error on failed.
Jobs expire after the backend retention window, so poll promptly.
Hebbrix Remember Many — Store MANY facts in one call. When you've extracted several distinct facts
from one user message, use this instead of calling hebbrix_remember N times —
it's one round-trip and one rate-limit hit, not N.
Pass a list of short, self-contained facts (one fact per string). Returns
{"created", "failed", "memory_ids", ...}. wait_for_index defaults to False
here (bulk writes are usually fire-and-forget); set True to block until all
are searchable.
Tier note: the single-rou
Hebbrix Create Procedure — Create a tenant-scoped learned procedure using canonical API fields.
Hebbrix List Procedures — List learned procedures owned by the current tenant.
Hebbrix Get Procedure — Get one tenant-owned procedure by id.
Hebbrix Update Procedure — Update mutable fields on one tenant-owned procedure; scope is immutable.
Hebbrix Execute Procedure — Execute one tenant-owned procedure and record its execution.

Operate Hebbrix?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Hebbrix Delete Procedure — Idempotently delete a tenant-owned procedure and its executions.
The API returns the same 204 for deleted, absent, and foreign-tenant ids so
this destructive tool cannot disclose another tenant's procedure identity.
Hebbrix Search — Semantic search over memories. Always call this BEFORE answering questions
that depend on prior context, decisions, or user preferences.
Zero-relevance padding rows are always dropped. If the fast API returns only
uncalibrated nearest-neighbour candidates with no lexical anchor, Hebbrix
automatically verifies them with calibrated retrieval and suppresses noise.
Raise `min_score` (0.0-1.0) to request an explicit absolute relevance floor.
Returns {"query", "count", "resul
Hebbrix Get — Fetch one memory by id, including its full content and metadata.
Hebbrix Update — Update a memory in place (keeps version history). Use this to CORRECT a
stored fact instead of remembering a contradicting copy. Pass the new content.
wait_for_index=True (default) requests a bounded indexing wait. Check
searchable; if false, poll hebbrix_get(id) instead of repeating the update.
Hebbrix Forget — Delete a memory by id.
A successful deletion returns ``deleted=true`` and the requested memory id;
an already-absent id retains the structured 404 error and adds
``already_absent=true``. This stable tool shape does not depend on whether
the API's successful DELETE response has a JSON body.
Hebbrix List — List recent memories in a collection.
Hebbrix History — Show the version history of a memory (how it changed over time, including
supersessions). Useful to see what a fact used to be.
Hebbrix Search Entities — List entities in the knowledge graph (people, organizations, tools, places),
optionally filtered by entity_type. Use for "who/what do I know about" questions.
Note: entities are enriched ASYNCHRONOUSLY after a write (not covered by
hebbrix_remember's wait_for_index) — a just-written fact's entities typically
appear here within ~30s, so an empty result right after a write is expected.
Hebbrix Entity Timeline — Bi-temporal timeline for one entity: what facts were true about it and when.
Use this for "what changed" / "what was true at time X" questions about a person,
company, or thing. Case-insensitive.
Hebbrix Graph Query — Traverse the knowledge graph OUT FROM a named entity to find its
relationships and facts. Pass an ISO `timestamp` to ask what was true at
that point in time (bi-temporal). depth = graph hops (1-5).
For a free-text question ("who works at Sequoia?"), use hebbrix_ask (it does
search + graph + profile and synthesizes an answer) — this endpoint traverses
from a known entity, not from prose.
Hebbrix Contradictions — Surface contradicting facts in the knowledge graph (e.g. two different values
for the same attribute). Pass a memory_id to check one memory, or omit to scan.
Use before trusting a fact that feels ambiguous.
Hebbrix Graph Status — Check whether one memory's asynchronous graph enrichment is ready.
``wait_seconds`` optionally performs bounded polling (maximum 30 seconds).
``ready`` means durable enrichment completed and the graph read succeeded.
graph_check.related_memory_count counts neighboring memories, NOT extracted
entity relationships. A zero count does not mean no edges were extracted.
This tool never fabricates edges from spelling conventions.
Hebbrix Confidence — Ask how confident the agent should be before acting on something, grounded in
stored memory and past decision outcomes. Call this before a consequential
autonomous action. Returns a confidence score and a recommended action.
If the action VIOLATES a stored numeric rule (e.g. opening a 600-line PR when
a memory says "PRs must be < 400 lines"), the result includes a
`constraint_conflict` block and recommended_action is do_not_act.
Hebbrix Ask — Answer a natural-language question from memory in ONE call. Searches
memories, synthesizes an answer with an LLM, and CITES the memory ids it used
— so you don't have to orchestrate hebbrix_search + hebbrix_graph_query +
profile yourself. Use for questions like "who works with me on Atlas and what
did we decide?".
Returns {"question", "answer", "citations":[{"id","content","score"}]}
plus the same authoritative safety envelope as search. If reasoning or its
evidence
Hebbrix Mark Used — Reinforce a memory you actually USED to answer (Hebbian recall): call this
when a retrieved memory was helpful (helpful=True, strengthens it) or was noise
(helpful=False, weakens it). Over time this makes the memories you rely on rank
higher and unused ones fade. `query` is the question it helped answer, if handy.
Hebbrix Log Decision — Record a decision the agent made and, if known, its outcome
(success | failure | partial). This feeds hebbrix_confidence so future
recommendations improve. Log both the choice and how it turned out.
Shortcut: right after a hebbrix_confidence check you can log just the
outcome (e.g. outcome="success") with no description — it auto-fills from
the thing you just asked about, closing the confidence -> action -> outcome
loop with one call.
Hebbrix Choose Action — Choose and RECORD an action before its result is known.
Use for repeatable decisions whose real outcome can be reported later: reply
strategy, workflow, tool, prompt, recommendation, intervention, or plan.
`policy_key` identifies that decision type (for example `support.reply`).
`actions` are stable machine keys. `context` contains only factors that may
change which action works. The first action is the safe baseline unless
`baseline_action` is supplied. Only offer actio
