Amazon Bedrock

OpenClaw can use Amazon Bedrock models via pi-ai’s Bedrock Converse streaming provider. Bedrock auth uses the AWS SDK default credential chain, not an API key.

Property	Value
Provider	amazon-bedrock
API	bedrock-converse-stream
Auth	AWS credentials (env vars, shared config, or instance role)
Region	AWS_REGION or AWS_DEFAULT_REGION (default: us-east-1)

Getting started

Choose your preferred auth method and follow the setup steps.

Access keys / env varsEC2 instance roles (IMDS)

Best for: developer machines, CI, or hosts where you manage AWS credentials directly.

1. Set AWS credentials on the gateway host

   export AWS_ACCESS_KEY_ID="EXAMPLE_AWS_ACCESS_KEY_ID"
   export AWS_SECRET_ACCESS_KEY="..."
   export AWS_REGION="us-east-1"
   # Optional:
   export AWS_SESSION_TOKEN="..."
   export AWS_PROFILE="your-profile"
   # Optional (Bedrock API key/bearer token):
   export AWS_BEARER_TOKEN_BEDROCK="..."

2. Add a Bedrock provider and model to your config

   No apiKey is required. Configure the provider with auth: "aws-sdk":

   {
     models: {
       providers: {
         "amazon-bedrock": {
           baseUrl: "https://bedrock-runtime.us-east-1.amazonaws.com",
           api: "bedrock-converse-stream",
           auth: "aws-sdk",
           models: [
             {
               id: "us.anthropic.claude-opus-4-6-v1:0",
               name: "Claude Opus 4.6 (Bedrock)",
               reasoning: true,
               input: ["text", "image"],
               cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
               contextWindow: 200000,
               maxTokens: 8192,
             },
           ],
         },
       },
     },
     agents: {
       defaults: {
         model: { primary: "amazon-bedrock/us.anthropic.claude-opus-4-6-v1:0" },
       },
     },
   }

Tip

With env-marker auth (AWS_ACCESS_KEY_ID, AWS_PROFILE, or AWS_BEARER_TOKEN_BEDROCK), OpenClaw auto-enables the implicit Bedrock provider for model discovery without extra config.

Best for: EC2 instances with an IAM role attached, using the instance metadata service for authentication.

1. Enable discovery explicitly

   When using IMDS, OpenClaw cannot detect AWS auth from env markers alone, so you must opt in:

   openclaw config set plugins.entries.amazon-bedrock.config.discovery.enabled true
   openclaw config set plugins.entries.amazon-bedrock.config.discovery.region us-east-1

2. Optionally add an env marker for auto mode

   If you also want the env-marker auto-detection path to work (for example, for openclaw status surfaces):

   export AWS_PROFILE=default
   export AWS_REGION=us-east-1

   You do not need a fake API key.

3. Verify models are discovered

   openclaw models list

Warning

The IAM role attached to your EC2 instance must have the following permissions:

• bedrock:InvokeModel
• bedrock:InvokeModelWithResponseStream
• bedrock:ListFoundationModels (for automatic discovery)
• bedrock:ListInferenceProfiles (for inference profile discovery)

Or attach the managed policy AmazonBedrockFullAccess.

Note

You only need AWS_PROFILE=default if you specifically want an env marker for auto mode or status surfaces. The actual Bedrock runtime auth path uses the AWS SDK default chain, so IMDS instance-role auth works even without env markers.

Automatic model discovery

OpenClaw can automatically discover Bedrock models that support streaming and text output. Discovery uses bedrock:ListFoundationModels and bedrock:ListInferenceProfiles, and results are cached (default: 1 hour).

How the implicit provider is enabled:

• If plugins.entries.amazon-bedrock.config.discovery.enabled is true, OpenClaw will try discovery even when no AWS env marker is present.
• If plugins.entries.amazon-bedrock.config.discovery.enabled is unset, OpenClaw only auto-adds the implicit Bedrock provider when it sees one of these AWS auth markers: AWS_BEARER_TOKEN_BEDROCK, AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY, or AWS_PROFILE.
• The actual Bedrock runtime auth path still uses the AWS SDK default chain, so shared config, SSO, and IMDS instance-role auth can work even when discovery needed enabled: true to opt in.

Note

For explicit models.providers["amazon-bedrock"] entries, OpenClaw can still resolve Bedrock env-marker auth early from AWS env markers such as AWS_BEARER_TOKEN_BEDROCK without forcing full runtime auth loading. The actual model-call auth path still uses the AWS SDK default chain.

Discovery config options

Config options live under plugins.entries.amazon-bedrock.config.discovery:

{
  plugins: {
    entries: {
      "amazon-bedrock": {
        config: {
          discovery: {
            enabled: true,
            region: "us-east-1",
            providerFilter: ["anthropic", "amazon"],
            refreshInterval: 3600,
            defaultContextWindow: 32000,
            defaultMaxTokens: 4096,
          },
        },
      },
    },
  },
}

Option	Default	Description
enabled	auto	In auto mode, OpenClaw only enables the implicit Bedrock provider when it sees a supported AWS env marker. Set true to force discovery.
region	AWS_REGION / AWS_DEFAULT_REGION / us-east-1	AWS region used for discovery API calls.
providerFilter	(all)	Matches Bedrock provider names (for example anthropic, amazon).
refreshInterval	3600	Cache duration in seconds. Set to 0 to disable caching.
defaultContextWindow	32000	Context window used for discovered models (override if you know your model limits).
defaultMaxTokens	4096	Max output tokens used for discovered models (override if you know your model limits).

Quick setup (AWS path)

This walkthrough creates an IAM role, attaches Bedrock permissions, associates the instance profile, and enables OpenClaw discovery on the EC2 host.

# 1. Create IAM role and instance profile
aws iam create-role --role-name EC2-Bedrock-Access \
  --assume-role-policy-document '{
    "Version": "2012-10-17",
    "Statement": [{
      "Effect": "Allow",
      "Principal": {"Service": "ec2.amazonaws.com"},
      "Action": "sts:AssumeRole"
    }]
  }'

aws iam attach-role-policy --role-name EC2-Bedrock-Access \
  --policy-arn arn:aws:iam::aws:policy/AmazonBedrockFullAccess

aws iam create-instance-profile --instance-profile-name EC2-Bedrock-Access
aws iam add-role-to-instance-profile \
  --instance-profile-name EC2-Bedrock-Access \
  --role-name EC2-Bedrock-Access

# 2. Attach to your EC2 instance
aws ec2 associate-iam-instance-profile \
  --instance-id i-xxxxx \
  --iam-instance-profile Name=EC2-Bedrock-Access

# 3. On the EC2 instance, enable discovery explicitly
openclaw config set plugins.entries.amazon-bedrock.config.discovery.enabled true
openclaw config set plugins.entries.amazon-bedrock.config.discovery.region us-east-1

# 4. Optional: add an env marker if you want auto mode without explicit enable
echo 'export AWS_PROFILE=default' >> ~/.bashrc
echo 'export AWS_REGION=us-east-1' >> ~/.bashrc
source ~/.bashrc

# 5. Verify models are discovered
openclaw models list

Advanced configuration

Inference profiles

OpenClaw discovers regional and global inference profiles alongside foundation models. When a profile maps to a known foundation model, the profile inherits that model’s capabilities (context window, max tokens, reasoning, vision) and the correct Bedrock request region is injected automatically. This means cross-region Claude profiles work without manual provider overrides.

Inference profile IDs look like us.anthropic.claude-opus-4-6-v1:0 (regional) or anthropic.claude-opus-4-6-v1:0 (global). If the backing model is already in the discovery results, the profile inherits its full capability set; otherwise safe defaults apply.

No extra configuration is needed. As long as discovery is enabled and the IAM principal has bedrock:ListInferenceProfiles, profiles appear alongside foundation models in openclaw models list.

Service tier

Some Bedrock models support a service_tier parameter to optimize for cost or latency. The following tiers are available:

Tier	Description
default	Standard Bedrock tier
flex	Discounted processing for workloads that can tolerate longer latency
priority	Prioritized processing for latency-sensitive workloads
reserved	Reserved capacity for steady-state workloads

Set serviceTier (or service_tier) via agents.defaults.params for Bedrock model requests, or per-model in `agents.defaults.models[”

“].params`:

```json5
{
  agents: {
    defaults: {
      params: {
        serviceTier: "flex", // applies to all models
      },
      models: {
        "amazon-bedrock/mistral.mistral-large-3-675b-instruct": {
          params: {
            serviceTier: "priority", // per-model override
          },
        },
      },
    },
  },
}
```

Valid values are `default`, `flex`, `priority`, and `reserved`. Not all
models support all tiers — if an unsupported tier is requested, Bedrock will
return a validation error. Note: the error message is somewhat misleading;
it may say "The provided model identifier is invalid" rather than indicating
an unsupported service tier. If you see this error, check whether the model
supports the requested tier.

Claude Opus 4.7 temperature

Bedrock rejects the temperature parameter for Claude Opus 4.7. OpenClaw omits temperature automatically for any Opus 4.7 Bedrock ref, including foundation model ids, named inference profiles, application inference profiles whose underlying model resolves to Opus 4.7 via bedrock:GetInferenceProfile, and dotted opus-4.7 variants with optional region prefixes (us., eu., ap., apac., au., jp., global.). No config knob is required, and the omission applies to both the request options object and the inferenceConfig payload field.

Guardrails

You can apply Amazon Bedrock Guardrails to all Bedrock model invocations by adding a guardrail object to the amazon-bedrock plugin config. Guardrails let you enforce content filtering, topic denial, word filters, sensitive information filters, and contextual grounding checks.

{
  plugins: {
    entries: {
      "amazon-bedrock": {
        config: {
          guardrail: {
            guardrailIdentifier: "abc123", // guardrail ID or full ARN
            guardrailVersion: "1", // version number or "DRAFT"
            streamProcessingMode: "sync", // optional: "sync" or "async"
            trace: "enabled", // optional: "enabled", "disabled", or "enabled_full"
          },
        },
      },
    },
  },
}

Option	Required	Description
guardrailIdentifier	Yes	Guardrail ID (e.g. abc123) or full ARN (e.g. arn:aws:bedrock:us-east-1:123456789012:guardrail/abc123).
guardrailVersion	Yes	Published version number, or "DRAFT" for the working draft.
streamProcessingMode	No	"sync" or "async" for guardrail evaluation during streaming. If omitted, Bedrock uses its default.
trace	No	"enabled" or "enabled_full" for debugging; omit or set "disabled" for production.

Warning

The IAM principal used by the gateway must have the bedrock:ApplyGuardrail permission in addition to the standard invoke permissions.

Embeddings for memory search

Bedrock can also serve as the embedding provider for memory search. This is configured separately from the inference provider — set agents.defaults.memorySearch.provider to "bedrock":

{
  agents: {
    defaults: {
      memorySearch: {
        provider: "bedrock",
        model: "amazon.titan-embed-text-v2:0", // default
      },
    },
  },
}

Bedrock embeddings use the same AWS SDK credential chain as inference (instance roles, SSO, access keys, shared config, and web identity). No API key is needed. When provider is "auto", Bedrock is auto-detected if that credential chain resolves successfully.

Supported embedding models include Amazon Titan Embed (v1, v2), Amazon Nova Embed, Cohere Embed (v3, v4), and TwelveLabs Marengo. See Memory configuration reference — Bedrock for the full model list and dimension options.

Notes and caveats

• Bedrock requires model access enabled in your AWS account/region.
• Automatic discovery needs the bedrock:ListFoundationModels and bedrock:ListInferenceProfiles permissions.
• If you rely on auto mode, set one of the supported AWS auth env markers on the gateway host. If you prefer IMDS/shared-config auth without env markers, set plugins.entries.amazon-bedrock.config.discovery.enabled: true.
• OpenClaw surfaces the credential source in this order: AWS_BEARER_TOKEN_BEDROCK, then AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY, then AWS_PROFILE, then the default AWS SDK chain.
• Reasoning support depends on the model; check the Bedrock model card for current capabilities.
• If you prefer a managed key flow, you can also place an OpenAI-compatible proxy in front of Bedrock and configure it as an OpenAI provider instead.
